During this time,all patients were stable without any specific drug therapy.Results There was moderate correlation between Doppler echocardiographic and right heart catheteriza- tion measurements of PASP(r =0.642,P【0.001).Using Bland-Altman analytic methods,the bias for the echocardio-graphic estimates of PASP was 6.65 mm Hg with 95%limits of agreement ranging from -47.62 to 34.30 mm Hg.There were 58.8%cases with absolute differences over 10 mm Hg between the two methods.Overestimation and underestimation of PASP by Doppler echocardiography occurred in 15.7% (16/102) and 43.1%(44),respectively.The magnitude of pressure underestimation and overestimation was insignificant (24.52±12.15 vs.25.69±16.09,P=0.765),while the corresponding diagnostic categories of severity that each subject would fall into for each technique are not in good agreement. The diagnostic categories of 16 overestimated patients were in accordance.During 44 underestimated patients,20.5%of patients had their pressure underestimated within one diagnostic category(minor error);4.5%of the underestimates were with two diagnostic categories(major error).Conclusions Transthoracic Doppler echocardiography may frequently be inaccurate in estimating PASP and could not replace the right heart catheterization.展开更多

Thirty healthy and adult rats were randomly divided into Warfarin group (n=10), Atorvastatin group (n=10) and normal control group (n=10). Caudal arterial pressure of rats was measured once a week, and 4 weeks later, aorta was obtained. Elastic fiber, collagen fiber and calcium accumulation in tunica media of cells were measured by Von Kossa staining. The results showed that warfarin treatment led to elevation of systolic blood pressure and aortic medial calcification. The chronic treatment also increased collagen, but decreased elastin in the aorta. However, the atorvastatin treatment had adverse effects. It was concluded that treatment with atorvastatin presented evidence of blood pressure lowing and calcification reducing. These data demonstrate that atorvastatin protected aortic media from warfarin-induced calcification and elevation of systolic blood pressure.展开更多

A previous study reported that an inter-arm systolic blood pressure difference (ΔSBP) of ≥10 mm Hg is associated with an increased risk of mortality. Aim: The aim was to identify the associations with absolute values of ΔSBP (|ΔSBP|) ≥10 mm Hg. Subjects and Methods: This study included 2481 patients. Patients with a body mass index ≥25 kg/m<sup>2</sup> were defined as obese. The group of A was defined as following: ankle-brachial index (ABI) was <0.9 or ≥1.3. ΔSBP was expressed as right arm BP minus left arm BP. |ΔSBP| ≥10 mm Hg were analyzed using multivariate logistic analysis. Results: |ΔSBP| ≥10 mm Hg was found in 6.0% of patients and |ΔSBP| < 5 mm Hg in 80.4%. In multivariate analysis, the odds ratios (ORs) of the associations with |ΔSBP| ≥10 mm Hg were significantly associated with abnormal ABI and obesity regardless of sex and age. Moreover, the OR of the combined effects of abnormal ABI and obesity was higher than that of abnormal ABI and obesity alone. Conclusion: |ΔSBP| ≥10 mm Hg was associated with abnormal ABI and obesity. In a primary care setting, blood pressure should be actively measured in both arms. This study suggests that the associations with |ΔSBP| ≥10 mm Hg may be a useful part of screening for abnormal ABI.展开更多

Me...Objectives This study sought to evaluate the diagnostic value of abnormal increase of postexercise systolic blood pressure (SBP) for detecting coronary artery disease (CAD) in patients with or without hypertension. Methods Treadmill exercise testing (TET) was conducted in 88 patients (40 CAD patients, 48 control subjects) with or without hypertension, each of whom underwent selective coronary angiography (CAG). The abnormal increase of postexercise SBP was defined as 10mmHg higher than earlier periods during the recovery phase (6 minutes) of exercise testing. Results The abnormal increase of postexercise SBP had higher sensitivity, specificity, and accuracy for detecting CAD than those of ST - segment depression in patients with or without hypertension. Its accuracy increased with the severity of CAD while decreased in patients with hypertension, and the increase value of SBP had a positive correlation with the extent of coronary artery lesion. The combination of ST - segment depression and abnormal increase of postexercise SBP diagnosed CAD most accurately in patients with hypertension. Conclusions Abnormal increase of postexercise SBP may be a useful index for diagnosing CAD.展开更多

Correlation analysis showed that APACHE II scores correlated significantly with SBPV and DBPV(P<0.01, r=0.732 and P<0.01, r=0.762). SBPV and DBPV were correlated with COR(P=0.018 and r=0.318; P=0.008 and r=0.353 respectively). However, SBPV and DBPV were not correlated with TNF-α, IL-10, and PCT(P>0.05). Logistic regression analysis of SBPV, DBPV, APACHE II score, and LAC was used to predict prognosis in terms of survival and non-survival rates. Receiver operating characteristics curve(ROC) showed that DBPV was a better predictor of survival rate with an AUC value of 0.890. However, AUC of SBPV, APACHE II score, and LAC was 0.746, 0.831 and 0.915, respectively.CONCLUSIONS: The values of SBPV, DBPV and non-dipper percentage are higher in patients with sepsis. DBPV and SBPV can be used to predict the survival rate of patients with sepsis.展开更多

The presence and severity of DR were determined by grading fundus photographs according to the Early Treatment Diabetic Retinopathy Study(ETDRS) retinopathy scale. Systolic and diastolic blood pressure(SBP and DBP) were recorded using an electronic sphygmomanometer. Intraocular pressure(IOP) was measured using an iCare rebound tonometer. MOPP was calculated using the formula MOPP = 2/3 [DBP + 1/3(SBP-DBP)]-IOP.Results In total, 1,857 patients who had gradable fundus photography and MOPP data were enrolled in this study. Male patients had a higher MOPP than female patients(52.25 ± 8.75 vs. 50.96 ± 8.74 mmHg, P = 0.002). Overall, both male and female patients with any type of DR, non-proliferative DR(NPDR), or non-sight-threatening DR(non-STDR) had significantly higher MOPP relative to patients without DR. Increased MOPP(per 1 mmHg) was in turn associated with the presence of any type of DR[odds ratio(OR) = 1.03, 95% confidence interval(CI) : 1.02–1.04], NPDR(OR = 1.03 95% CI: 1.02–1.04),and non-STDR(OR = 1.03, 95% CI: 1.01–1.04) after adjusting for confounders. Increased MOPP(per 1 mmHg) was also associated with an increased likelihood of macular edema(OR = 1.02, 95% CI:1.01–1.04).Conclusions The results suggest that increased MOPP was associated with DR and macular edema in northeastern Chinese patients with T2 DM.展开更多

The former can be measured by pressure pain sensitivity (PPS) of the sternum, and the latter by the PPS and systolic blood pressure (SBP) response to a tilt table test (TTT). Beta-blocker treatment reduces the efferent beta-adrenergic ANS function, and thus, the physiological stress response. Objective: To test the effect of beta-blockers on changes in depression score in patients with IHD, as well as the influence on persistent stress and ANS dysfunction. Methods: Three months of non-pharmacological intervention aiming at reducing PPS and depression score in patients with stable IHD. Beta-blocker users (N = 102) were compared with non-users (N = 75), with respect to signs of depression measured by the Major Depressive Inventory questionnaire (MDI), resting PPS, and PPS and SBP response to TTT. Results: MDI score decreased 30% in non-users (p = 0.005) compared to 4% (p > 0.1) among users (between-group p = 0.003;effect size = 0.4). Resting PPS decreased in both the groups. Among most vulnerable patients with MDI ≥ 15, reductions in MDI score and resting PPS score correlated in non-users, only (r = 0.69, p = 0.007). Reduction in resting PPS correlated with an increase in PPS and SBP response to TTT. Conclusions: Stress intervention in patients with IHD was anti-depressive in non-users, only. Similarly, the association between the reduction in depression, reduction in persistent stress, and restoration of ANS dysfunction was only seen in non-users, suggesting a central role of beta-adrenergic receptors in the association between these factors.展开更多

Hence, we sought to measure the effect of almond milk on body measurements such as body weight, body mass index and waist and hip circumference, in addition to diastolic and systolic blood pressures. Thirty volunteers of both sexes participated in the study, with a mean age of 23.27 ± 6.20 years. The study was conducted over 4 weeks, and the results showed that daily substitution of one serving of dairy product with one cup (240 ML) of almond milk significantly decreased body weight, body mass index and waist and hip circumference, However, no effects were observed on blood pressures.展开更多

Methods: Data analysis was performed in 95 healthy normotensive premeno-pausal women at baseline and 84 after 5-year follow-up (age, 49.9 ± 1.9 years;BMI, 23.3 ± 2.2 kg/m2;resting BP, 117/73 ± 11.8/7.6 mmHg). Blood pressure was measured at rest and during a progressive exercise test on treadmill. Women were divided into two groups according to their peak ESBP <190 mmHg vs. ≥190 mmHg. Other outcome measures were: cardiorespiratory fitness (VO2 peak), body composition, body fat distribution and fasting plasma lipids, glucose and insulin levels. Results: 15% and 27% of women presented an exaggerated peak ESBP response (≥190 mmHg) at baseline and year 5 respectively. Linear mixed model repeated measures analysis revealed higher values of fasting glucose, resting systolic and diastolic BP in women with an exaggerated peak ESBP (≥190 mmHg) compared to women with a peak ESBP (<190 mmHg). No significant difference was observed between the two groups for VO2 peak, body composition and body fat distribution indices and other cardiometabolic risk factors. Finally, baseline peak ESBP was not a significant risk factor for future resting hypertension (OR: 2.96, 95%CI [0.48 - 18.12];P = 0.24). Conclusion: Our results, despite being non significant, are of great interest because in healthy and active premenopausal women, exaggerated peak ESBP is not predictive of future hypertension after 5-year follow-up throughout menopause transition.展开更多

The aim of this study was to determine the prevalence and associated factors of ALL in diabetic patients in treatment at the Oueme-Plateau Provincial Teaching Hospital. Methods: This was a cross-sectional, descriptive, and analytical study from July 12 to October 10, 2021, at the Oueme-Plateau Provincial Teaching Hospital in Porto-Novo. ALL was screened by performing systolic pressure index (SPI) in all diabetic patients aged at least 18 years, seen in consultation or hospitalization during the study period and who had given their consent. Results: The study registered 165 diabetics and 98.2% of them were type 2. Subjects aged between 55 and 65 years were the most represented (33.9%), with an average age of 59.4 years. Women were in the majority (61.2%), with a sex ratio of 0.6. High blood pressure was associated with diabetes in 61.2% of patients. The prevalence of ALL was 48.5% (80 patients). Obliterative arteriopathy of the lower limbs (OALL) was observed in 70 patients (42.4%), mediacalcosis in 8 patients (4.8%), and mixed arteriopathy in 2 patients (1.2%). In 88.5% of patients, the pathology was symptomless. Factors significantly associated with ALL included advanced age (p = 0.01), the age of the glycemic imbalance (p = 0.03), lack of regular physical activity (p = 0.001) and dyslipidemia (p = 0.008). Conclusion: Pelvic limb arteriopathy is usual among diabetics at Oueme-Plateau Provincial Teaching Hospital. The use of SPI, which enables diagnosis, requires simple, low-cost means, and should be encouraged.展开更多

文摘Background Transthoracic Doppler echocardiography is recommended for screening the presence of pulmonary hypertension(PH).However,the accuracy of pulmonary artery systolic pressure(PASP) estimated by Doppler echocardiographic is still unknown.Methods We conducted a retrospective study on 102 patients with idiopathic pulmonary arterial hypertension who underwent Doppler echocar-diography within 72 hours before right heart catheterization. During this time,all patients were stable without any specific drug therapy.Results There was moderate correlation between Doppler echocardiographic and right heart catheteriza- tion measurements of PASP(r =0.642,P【0.001).Using Bland-Altman analytic methods,the bias for the echocardio-graphic estimates of PASP was 6.65 mm Hg with 95%limits of agreement ranging from -47.62 to 34.30 mm Hg.There were 58.8%cases with absolute differences over 10 mm Hg between the two methods.Overestimation and underestimation of PASP by Doppler echocardiography occurred in 15.7% (16/102) and 43.1%(44),respectively.The magnitude of pressure underestimation and overestimation was insignificant (24.52±12.15 vs.25.69±16.09,P=0.765),while the corresponding diagnostic categories of severity that each subject would fall into for each technique are not in good agreement. The diagnostic categories of 16 overestimated patients were in accordance.During 44 underestimated patients,20.5%of patients had their pressure underestimated within one diagnostic category(minor error);4.5%of the underestimates were with two diagnostic categories(major error).Conclusions Transthoracic Doppler echocardiography may frequently be inaccurate in estimating PASP and could not replace the right heart catheterization.

文摘Background:No convenient,inexpensive,and non-invasive screening tools exist to identify pulmonary hypertension(PH)-left heart disease(LHD)patients during the early stages of the disease course.This study investigated whether different methods of lung ultrasound(LUS)could be used for the initial investigation of PH-LHD.Methods:This was a single-center prospective observational study which was performed in the Zigong Fourth People’s Hospital.We consecutively enrolled patients with heart failure(HF)admitted to the emergency intensive care unit from January 2018 to May 2020.Transthoracic echocardiography and LUS were performed within 24 h before discharge.We used the Spearman coefficient for correlation analysis between ultrasound scores and pulmonary arterial systolic pressure(PASP).Bland-Altman plots were generated to inspect possible bias,and receiver operating characteristic(ROC)curves were calculated to assess the relationship between ultrasound scores and an intermediate and high echocardiographic probability of PH-LHD.Results:Seventy-one patients were enrolled in this study,with an overall median age of 79(interquartile range:71.5–84.0)years.Among the 71 patients,36(50.7%)cases were male,and 26(36.6%)had an intermediate and high echocardiographic probability of PH.All four LUS scores in patients with an intermediate and high probability of PH were significantly higher than in patients with a low probability of PH(P<0.05).The correlation coefficient(r)between different LUS scoring methods and PASP was moderate for the 6-zone(r=0.455,P<0.001),8-zone(r=0.385,P=0.001),12-zone(r=0.587,P<0.001),and 28-zone(r=0.535,P<0.001)methods.In Bland-Altman plots,each of the four LUS scoring methods had a good agreement with PASP(P<0.001).The 8-zone and 12-zone methods showed moderately accurate discriminative values in differentiating patients with an intermediate and high echocardiographic probability of PH(P<0.05).
文摘Background:High blood pressure(BP)is a major contributor to mortality and cardiovascular diseases.Despite the known benefits of exercise for reducing BP,it is crucial to identify the most effective physical activity(PA)intervention.This systematic review and network meta-analysis(NMA)aimed to evaluate the available evidence on the effectiveness of various PA interventions for reducing BP and to determine their hierarchy based on their impact on BP.Methods:A search of PubMed,SPORTDiscus,PsycINFO,Web of Science,CINAHL,Cochrane,and Eric databases was conducted up to December 2022 for this systematic review and NMA.Randomized controlled trials and quasi-experimental studies targeting healthy children and adolescents aged 6-12 years old were included in this study.Only studies that compared controlled and intervention groups using PA or exercise as the major influence were included.We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)guidelines.Three independent investigators performed the literature screening,data extraction,and risk of bias assessment.We used Bayesian arm-based NMA to synthesize the data.The primary outcomes were systolic BP and diastolic BP.We calculated the mean differences(MDs)in systolic BP and diastolic BP before and after treatment.Mean treatment differences were estimated using NMA and random-effect models.Results:We synthesized 27 studies involving 15,220 children and adolescents.PA combined with nutrition and behavior change was the most effective intervention for reducing both systolic BP and diastolic BP(MD=-8.64,95%credible interval(95%CI):-11.44 to-5.84;MD=-6.75,95%CI:-10.44 to-3.11),followed by interventions with multiple components(MD=-1.39,95%CI:-1.94 to-0.84;MD=-2.54,95%CI:-4.89 to-0.29).Conclusion:Our findings suggest that PA interventions incorporating nutrition and behavior change,followed by interventions with multiple components,are most effective for reducing both systolic BP and diastolic BP in children and adolescents.

文摘Background:Pulmonary artery systolic pressure(PASP)has often been evaluated as an indicator of heart failure,but the relationship between PASP and the prognosis of elderly patients with acute myocardial infarction(AMI)is not well understood.Methods:The medical data of 3460 hospitalized elderly patients diagnosed with AMI between January 2013 and June 2018 were reviewed.PASP was calculated usingtransthoracic color Doppler ultrasonography.Patients were grouped accordingtotheir admission PASP results as follows:Group A,PASP≤30 mmHg;Group B,30 mmHg<PASP≤50 mmHg;and Group C,PASP≥51 mmHg.The primary endpoint was all-cause death 6 months following AMI.Multiple Cox regression analysis was used to identify independent risk factors for 6-month mortality in elderly patients with AMI.Results:PASP was associated with age,Killip classification,AMI site,and decreased ejection fraction in elderly patients.After adjusting for clinical and echocardiographic parameters in the Cox model,PASP was found to be significantly related to all-cause mortality.In receiver operating characteristic analysis,a PASP of>34 mmHg had a sensitivity of 62.3%and specificity of 65.7%for predicting 6-month all-cause death after AMI.Conclusion:PASP at admission is a useful marker for predicting short-term mortality in elderly patients with AMI.This finding could be used to help identify high-risk patients and make appropriate clinical decisions.
文摘The effect of atorvastatin on warfarin-induced aortic medial calcification and systolic blood pressure (SBP) of rats induced by warfarin was studied. Thirty healthy and adult rats were randomly divided into Warfarin group (n=10), Atorvastatin group (n=10) and normal control group (n=10). Caudal arterial pressure of rats was measured once a week, and 4 weeks later, aorta was obtained. Elastic fiber, collagen fiber and calcium accumulation in tunica media of cells were measured by Von Kossa staining. The results showed that warfarin treatment led to elevation of systolic blood pressure and aortic medial calcification. The chronic treatment also increased collagen, but decreased elastin in the aorta. However, the atorvastatin treatment had adverse effects. It was concluded that treatment with atorvastatin presented evidence of blood pressure lowing and calcification reducing. These data demonstrate that atorvastatin protected aortic media from warfarin-induced calcification and elevation of systolic blood pressure.
文摘Dear editor, We read with pleasure the well-designed study by Butler et al of electrical cardioversion of emergency department patients with atrial fibrillation. We appreciate their analysis of the distinctives of procedural sedation when employed for this indication. Understanding the dosing adjustments to propofol undertaken by their sedationists will help us more carefully evaluate our own approach to sedating patients undergoing electrical cardioversion of atrial fibrillation.
文摘Background: In new outpatients, blood pressure should be measured in both arms. A previous study reported that an inter-arm systolic blood pressure difference (ΔSBP) of ≥10 mm Hg is associated with an increased risk of mortality. Aim: The aim was to identify the associations with absolute values of ΔSBP (|ΔSBP|) ≥10 mm Hg. Subjects and Methods: This study included 2481 patients. Patients with a body mass index ≥25 kg/m<sup>2</sup> were defined as obese. The group of A was defined as following: ankle-brachial index (ABI) was <0.9 or ≥1.3. ΔSBP was expressed as right arm BP minus left arm BP. |ΔSBP| ≥10 mm Hg were analyzed using multivariate logistic analysis. Results: |ΔSBP| ≥10 mm Hg was found in 6.0% of patients and |ΔSBP| < 5 mm Hg in 80.4%. In multivariate analysis, the odds ratios (ORs) of the associations with |ΔSBP| ≥10 mm Hg were significantly associated with abnormal ABI and obesity regardless of sex and age. Moreover, the OR of the combined effects of abnormal ABI and obesity was higher than that of abnormal ABI and obesity alone. Conclusion: |ΔSBP| ≥10 mm Hg was associated with abnormal ABI and obesity. In a primary care setting, blood pressure should be actively measured in both arms. This study suggests that the associations with |ΔSBP| ≥10 mm Hg may be a useful part of screening for abnormal ABI.
文摘Objectives This study sought to evaluate the diagnostic value of abnormal increase of postexercise systolic blood pressure (SBP) for detecting coronary artery disease (CAD) in patients with or without hypertension. Methods Treadmill exercise testing (TET) was conducted in 88 patients (40 CAD patients, 48 control subjects) with or without hypertension, each of whom underwent selective coronary angiography (CAG). The abnormal increase of postexercise SBP was defined as 10mmHg higher than earlier periods during the recovery phase (6 minutes) of exercise testing. Results The abnormal increase of postexercise SBP had higher sensitivity, specificity, and accuracy for detecting CAD than those of ST - segment depression in patients with or without hypertension. Its accuracy increased with the severity of CAD while decreased in patients with hypertension, and the increase value of SBP had a positive correlation with the extent of coronary artery lesion. The combination of ST - segment depression and abnormal increase of postexercise SBP diagnosed CAD most accurately in patients with hypertension. Conclusions Abnormal increase of postexercise SBP may be a useful index for diagnosing CAD.
文摘Virtual reality(VR)seems to have the potential to provide opportunities to promote physical activity(PA)in a fun way.This paper aimed to examine the acute effects of three different virtual reality-based exercise bikes on young adults’blood pressure(BP)and feelings compared to a traditional exercise cycling session.Four exercise sessions(immersive VR cycling,two non-immersive VR cycling,and traditional cycling)were completed by 36 young adults(22 females;Mage=23.6 years).BP was measured immediately before and after each session using a BP cuff and exercise-induced feelings were assessed via an established survey immediately after each session.Parti-cipants’previous experience with VR was used as the covariate in the ANCOVA with repeated measures.Signif-icant main effects were observed across cycling sessions for systolic blood pressure[F(2,29)=3.04,p=0.02,(η^(2)=0.38)]and feelings[F(3,32)=7.74,p<0.01,η^(2)=.42].In particular,immersive VR and traditional cycling signif-icantly increased systolic blood pressure compared to the two non-immersive VR sessions.Moreover,immersive VR significantly increased feelings compared to the two non-immersive VR sessions,whereas these two non-immersive VR exercises had significantly greater increased feelings compared to traditional cycling,respectively.Findings suggest immersive VR-based exercise cycling may lead to higher exercise intensities compared to non-immersive VR cycling.Further,immersive VR cycling yielded higher feelings compared to non-immersive VR and traditional cycling.Thus,immersive VR-based exercise can be a fun and physically active health promotion tool among young adults.
文摘Objective:This study aims to investigate the impact of tricuspid regurgitation(TR)severity on the accuracy of echocardiographic estimation of systolic pulmonary arterial pressure(sPAP)in patients with pulmonary arterial hypertension(PAH).Methods:Patients who were diagnosed with PAH and had a right heart catheterization(RHC)and echocardiography examination were selected retrospectively from May 2018 to December 2021.sPAP measured by RHC is used as the gold standard.A difference in sPAP of less than 10 mmHg between echocardiographic estimation by peak TR velocity and RHC measurement was defined as accurate,with a difference≥10 mmHg considered inaccurate.The factors affecting the accuracy of echocardiographic sPAP estimation were analyzed by univariate and multivariate analysis.Results:A total of 138 patients aged(45.57±15.97)years with PAH were enrolled.sPAP measured by echocardiography and RHC were(80.83±23.46)and(81.62±30.05)mmHg,respectively.The values of the 2 methods were highly correlated(r=0.809,P<0.01)and Bland-Altman plots showed good consistency.The accuracy rate of sPAP estimation by echocardiography was 42.03%(58/138).In the 57.97%(80/138)of patients where echocardiography was inaccurate,sPAP was overestimated in 28.26%(39/138)and underestimated in 29.71%(41/138).Univariate analysis showed that there was a statistically significant difference between the accurate and inaccurate groups in World Health Organization-Function Class,N-terminal pro-B-type natriuretic peptide,severity of TR,tricuspid annular plane systolic excursion(TAPSE),sPAP-RHC,mean pulmonary artery pressure,pulmonary vascular resistance(P<0.05).Multivariate logistic regression analyses identified the TR severity(odds ratio=2.292,95%confidence interval:1.126–4.667,P=0.022)and TAPSE(odds ratio=0.733,95%confidence interval:0.621–0.865,P<0.001)as independent predictors for the accuracy of echocardiographic sPAP estimation.Conclusion:Higher TR severity and lower TAPSE values reduce the accuracy of sPAP estimated by echocardiography.Therefore,TR severity and right heart function should be considered when echocardiography is used to estimate sPAP by the TR velocity.
文摘Objective:To evaluate the efficacy of combination perindopril/amlodipine tablets in patients with high-altitude hypertension who were previously unable to control their blood pressure with monotherapy.Methods:A total of 151 patients with high-altitude hypertension whose blood pressure remained inadequately controlled with previous monotherapy were enrolled in this study.All patients received an 8-week treatment with a combination of perindopril/amlodipine tablets,consisting of perindopril 10 mg/day and amlodipine 5 mg/day.Blood pressure measurements,including both diastolic and systolic pressures,were taken at baseline,and after 2,4,6,and 8 weeks of treatment.Results:After 8 weeks of treatment,there was a significant reduction in both average systolic and diastolic blood pressure compared to baseline(P<0.0001).Specifically,the average systolic blood pressure decreased by 24.45±13.75 mmHg,and the average diastolic blood pressure decreased by 13.37±8.40 mmHg.The overall heart rate showed no significant changes during the treatment period.Conclusion:A combination of perindopril/amlodipine tablets significantly improved blood pressure control in patients with high-altitude hypertension after 8 weeks of treatment.These results support the efficacy of combination perindopril/amlodipine as a viable treatment option for high-altitude hypertension.
文摘BACKGROUND: This study was undertaken to observe the characteristics of blood pressure variability(BPV) and sepsis and to investigate changes in blood pressure and its value on the severity of illness in patients with sepsis.METHODS: Blood parameters, APACHE II score, and 24-hour ambulatory BP were analyzed in 89 patients with sepsis.RESULTS: In patients with APACHE II score>19, the values of systolic blood pressure(SBPV), diasystolic blood pressure(DBPV), non-dipper percentage, cortisol(COR), lactate(LAC), platelet count(PLT) and glucose(GLU) were significantly higher than in those with APACHE II score ≤19(P<0.05), whereas the values of procalcitonin(PCT), white blood cell(WBC), creatinine(Cr), PaO2, C-reactive protein(CRP), adrenocorticotropic hormone(ACTH) and tumor necrosis factor α(TNF-α) were not statistically significant(P>0.05). Correlation analysis showed that APACHE II scores correlated significantly with SBPV and DBPV(P<0.01, r=0.732 and P<0.01, r=0.762). SBPV and DBPV were correlated with COR(P=0.018 and r=0.318; P=0.008 and r=0.353 respectively). However, SBPV and DBPV were not correlated with TNF-α, IL-10, and PCT(P>0.05). Logistic regression analysis of SBPV, DBPV, APACHE II score, and LAC was used to predict prognosis in terms of survival and non-survival rates. Receiver operating characteristics curve(ROC) showed that DBPV was a better predictor of survival rate with an AUC value of 0.890. However, AUC of SBPV, APACHE II score, and LAC was 0.746, 0.831 and 0.915, respectively.CONCLUSIONS: The values of SBPV, DBPV and non-dipper percentage are higher in patients with sepsis. DBPV and SBPV can be used to predict the survival rate of patients with sepsis.

文摘In this study,single-channel photoplethysmography(PPG)signals were used to estimate the heart rate(HR),diastolic blood pressure(DBP),and systolic blood pressure(SBP).A deep learning model was proposed using a long-term recurrent convolutional network(LRCN)modified from a deep learning algorithm,the convolutional neural network model of the modified inception deep learning module,and a long short-term memory network(LSTM)to improve the model’s accuracy of BP and HR measurements.The PPG data of 1,551 patients were obtained from the University of California Irvine Machine Learning Repository.How to design a filter of PPG signals and how to choose the loss functions for deep learning model were also discussed in the study.Finally,the stability of the proposed model was tested using a 10-fold cross-validation,with an MAE±SD of 2.942±5.076 mmHg for SBP,1.747±3.042 mmHg for DBP,and 1.137±2.463 bpm for the HR.Compared with its existing counterparts,the model entailed less computational load and was more accurate in estimating SBP,DBP,and HR.These results established the validity of the model.

文摘Objective To evaluate the association between diabetic retinopathy(DR) and mean ocular perfusion pressure(MOPP) in patients with type 2 diabetes mellitus(T2 DM).Methods Patients from the Fushun Diabetic Retinopathy Cohort Study(FS-DIRECT), a communitybased prospective cohort study conducted in northeast China, were included in this study. The presence and severity of DR were determined by grading fundus photographs according to the Early Treatment Diabetic Retinopathy Study(ETDRS) retinopathy scale. Systolic and diastolic blood pressure(SBP and DBP) were recorded using an electronic sphygmomanometer. Intraocular pressure(IOP) was measured using an iCare rebound tonometer. MOPP was calculated using the formula MOPP = 2/3 [DBP + 1/3(SBP-DBP)]-IOP.Results In total, 1,857 patients who had gradable fundus photography and MOPP data were enrolled in this study. Male patients had a higher MOPP than female patients(52.25 ± 8.75 vs. 50.96 ± 8.74 mmHg, P = 0.002). Overall, both male and female patients with any type of DR, non-proliferative DR(NPDR), or non-sight-threatening DR(non-STDR) had significantly higher MOPP relative to patients without DR. Increased MOPP(per 1 mmHg) was in turn associated with the presence of any type of DR[odds ratio(OR) = 1.03, 95% confidence interval(CI) : 1.02–1.04], NPDR(OR = 1.03 95% CI: 1.02–1.04),and non-STDR(OR = 1.03, 95% CI: 1.01–1.04) after adjusting for confounders. Increased MOPP(per 1 mmHg) was also associated with an increased likelihood of macular edema(OR = 1.02, 95% CI:1.01–1.04).Conclusions The results suggest that increased MOPP was associated with DR and macular edema in northeastern Chinese patients with T2 DM.
文摘BACKGROUND Obesity has evolved into a global pandemic.The prevalence of obesity and hypertension in eastern North Carolina are comparable,if not higher,than the national prevalence.In the United States,an estimated 34%of adults have hypertension,the most modifiable risk factor for heart disease and stroke.Lifestyle and pharmacological interventions often do not provide sustained weight loss in obese patients.Bariatric surgery offers an effective weight reduction with short-and long-term health improvements;however,a higher body mass index is associated with higher surgical morbidity and mortality,longer hospitalization,and increasing rates of 30-day readmission due to comorbidities.Intragastric balloon may bridge a critical gap in the treatment of obesity.The objective of this paper is to showcase the impact of endoscopic bariatric therapy on blood pressure reduction.AIM To investigate the impact of intragastric balloon on blood pressure reduction.METHODS A retrospective chart review was conducted from January 1,2016 to January 31,2019 of consecutive adults who received intragastric balloon therapy(IGBT)in a gastroenterology private practice in Eastern North Carolina.The balloon was introduced into the stomach under endoscopic guidance,and while in the region of the gastric body,inflation with saline was performed at increments of 50 mL until target volume between 500 to 650 mL of saline was attained depending on the patient's gastric capacity.No procedural complications were noted during endoscopic placement and removal of the balloon.A cohort study design was used for data analysis.A total of 172 patients had the Orbera^(■)intragastric balloon placed.Of the 172 patients who had IGBT at baseline,11 patients(6.4%)requested early balloon removal due to foreign body sensation(n=1),and/or intolerable gastrointestinal adverse events(n=10).The reported gastrointestinal adverse events were nausea,vomiting,abdominal pain,and diarrhea.Eventually,6-mo follow-up data were available for only 140 patients.As a result,only the 140 available at the 6-mo follow-up were included in the analysis.Univariate,bivariate,and multivariate statistical analyses were performed.Specifically,scatterplots were created to show the relationship between weight and blood pressure,and paired two-sample t-test was carried out to determine if there was a significant reduction in weight before and after the IGBT.Multiple regressions were also performed to examine the association between participants’total body weight and blood pressure.The outcome variables for the multiple regression were systolic and diastolic blood pressure measured as continuous variables.This was followed by logistic regression analyses to determine the association between total body weight and hypertension at 6-mo post-implantation.The outcome variables for the logistic regression were systolic blood pressure–nonhypertensive(140 mmHg or less)or hypertensive(greater than 140 mmHg),and diastolic blood pressure–non-hypertensive(90 mmHg or less)or hypertensive(greater than 90 mmHg).All authors had access to the study data and reviewed and approved the final manuscript.All statistical analyses were done using STATA 14®.RESULTS The study included 15%males and 85%females.50%of the patients were white and just over 22%were non-white,and about 27%declined to give their race.The average baseline patients’weight prior to IGBT was 231.61 Lbs.(SD=46.53 Lbs.).However,the average patients’weight after IGBT at the 6-mo follow-up was 203.88 Lbs.(SD=41.04 Lbs.).Hence,on average,the percent total body weight loss at 6-mo is 11.97 after IGBT.The logistic regression performed revealed that weight(β=0.0140,P<0.000)and age(β=0.0534,P<0.000)are important factors in determining systolic blood pressure after IGBT.None of the other demographic characteristics or indicated comorbidities were found to be significant.CONCLUSION IGBT can be an effective short-term weight reduction modality with a relatively little risk of adverse event.Due to its improvement on systolic blood pressure,IGBT may help reduce cardiovascular risk.
文摘Background: Depression and ischemic heart disease (IHD) are associated with persistent stress and autonomic nervous system (ANS) dysfunction. The former can be measured by pressure pain sensitivity (PPS) of the sternum, and the latter by the PPS and systolic blood pressure (SBP) response to a tilt table test (TTT). Beta-blocker treatment reduces the efferent beta-adrenergic ANS function, and thus, the physiological stress response. Objective: To test the effect of beta-blockers on changes in depression score in patients with IHD, as well as the influence on persistent stress and ANS dysfunction. Methods: Three months of non-pharmacological intervention aiming at reducing PPS and depression score in patients with stable IHD. Beta-blocker users (N = 102) were compared with non-users (N = 75), with respect to signs of depression measured by the Major Depressive Inventory questionnaire (MDI), resting PPS, and PPS and SBP response to TTT. Results: MDI score decreased 30% in non-users (p = 0.005) compared to 4% (p > 0.1) among users (between-group p = 0.003;effect size = 0.4). Resting PPS decreased in both the groups. Among most vulnerable patients with MDI ≥ 15, reductions in MDI score and resting PPS score correlated in non-users, only (r = 0.69, p = 0.007). Reduction in resting PPS correlated with an increase in PPS and SBP response to TTT. Conclusions: Stress intervention in patients with IHD was anti-depressive in non-users, only. Similarly, the association between the reduction in depression, reduction in persistent stress, and restoration of ANS dysfunction was only seen in non-users, suggesting a central role of beta-adrenergic receptors in the association between these factors.
文摘In recent years, the demand for almond milk and its sales has increased owing to consumers’ perceptions about its health benefits. Hence, we sought to measure the effect of almond milk on body measurements such as body weight, body mass index and waist and hip circumference, in addition to diastolic and systolic blood pressures. Thirty volunteers of both sexes participated in the study, with a mean age of 23.27 ± 6.20 years. The study was conducted over 4 weeks, and the results showed that daily substitution of one serving of dairy product with one cup (240 ML) of almond milk significantly decreased body weight, body mass index and waist and hip circumference, However, no effects were observed on blood pressures.
文摘Objective: To investigate if an exaggerated peak exercise systolic blood pressure (peak ESBP) is associated with alteration of cardiometabolic risk factors and predict future resting hypertension in middle aged women. Methods: Data analysis was performed in 95 healthy normotensive premeno-pausal women at baseline and 84 after 5-year follow-up (age, 49.9 ± 1.9 years;BMI, 23.3 ± 2.2 kg/m2;resting BP, 117/73 ± 11.8/7.6 mmHg). Blood pressure was measured at rest and during a progressive exercise test on treadmill. Women were divided into two groups according to their peak ESBP <190 mmHg vs. ≥190 mmHg. Other outcome measures were: cardiorespiratory fitness (VO2 peak), body composition, body fat distribution and fasting plasma lipids, glucose and insulin levels. Results: 15% and 27% of women presented an exaggerated peak ESBP response (≥190 mmHg) at baseline and year 5 respectively. Linear mixed model repeated measures analysis revealed higher values of fasting glucose, resting systolic and diastolic BP in women with an exaggerated peak ESBP (≥190 mmHg) compared to women with a peak ESBP (<190 mmHg). No significant difference was observed between the two groups for VO2 peak, body composition and body fat distribution indices and other cardiometabolic risk factors. Finally, baseline peak ESBP was not a significant risk factor for future resting hypertension (OR: 2.96, 95%CI [0.48 - 18.12];P = 0.24). Conclusion: Our results, despite being non significant, are of great interest because in healthy and active premenopausal women, exaggerated peak ESBP is not predictive of future hypertension after 5-year follow-up throughout menopause transition.
文摘Introduction: The distribution of arteriopathy of the lower limbs (ALL) is not familiar in the city of Porto-Novo. The aim of this study was to determine the prevalence and associated factors of ALL in diabetic patients in treatment at the Oueme-Plateau Provincial Teaching Hospital. Methods: This was a cross-sectional, descriptive, and analytical study from July 12 to October 10, 2021, at the Oueme-Plateau Provincial Teaching Hospital in Porto-Novo. ALL was screened by performing systolic pressure index (SPI) in all diabetic patients aged at least 18 years, seen in consultation or hospitalization during the study period and who had given their consent. Results: The study registered 165 diabetics and 98.2% of them were type 2. Subjects aged between 55 and 65 years were the most represented (33.9%), with an average age of 59.4 years. Women were in the majority (61.2%), with a sex ratio of 0.6. High blood pressure was associated with diabetes in 61.2% of patients. The prevalence of ALL was 48.5% (80 patients). Obliterative arteriopathy of the lower limbs (OALL) was observed in 70 patients (42.4%), mediacalcosis in 8 patients (4.8%), and mixed arteriopathy in 2 patients (1.2%). In 88.5% of patients, the pathology was symptomless. Factors significantly associated with ALL included advanced age (p = 0.01), the age of the glycemic imbalance (p = 0.03), lack of regular physical activity (p = 0.001) and dyslipidemia (p = 0.008). Conclusion: Pelvic limb arteriopathy is usual among diabetics at Oueme-Plateau Provincial Teaching Hospital. The use of SPI, which enables diagnosis, requires simple, low-cost means, and should be encouraged.
文摘Background:Individuals with diabetes have greater central arterial stiffness,wave reflections,and hemodynamics,all of which promote the accelerated cardiovascular pathology seen in this population.Acute aerobic exercise has been shown to be an effective strategy for reducing central arterial stiffness,wave reflections,and hemodynamics in healthy individuals;however,the effects of acute aerobic exercise in reducing these outcomes is not well established in people with diabetes.Recently,implementation of high-intensity interval exercise(HIIE)has shown superior improvements in cardiovascular health outcomes when compared to traditional aerobic exercise.Yet,the effect of HIIE on the aforementioned outcomes in people with diabetes is not known.The purpose of this study was to(i)describe the central arterial stiffness,wave reflections,and hemodynamic responses to a bout of HIIE and moderate-intensity continuous exercise(MICE)in adults with diabetes;and(ii)compare the effects of HIIE and MICE on the aforementioned outcomes.Methods:A total of 24 adult men and women(aged 29-59 years old)with type 1(n=12)and type 2(n=12)diabetes participated in a randomized cross-over study.All participants completed the following protocols:(i)HIIE:cycling for 4×4 min at 85%-95%of heart rate peak(HR_(peak)),interspersed with 3 min of active recovery at 60%-70%HR_(peak);(ii)MICE:33 min of continuous cycling at 60%-70%HR_(peak);and(iii)control(CON):lying quietly in a supine position for 30 min.Results:A significant group£time effect was found for changes in central systolic blood pressure(F=3.20,p=0.01)with a transient reduction for the HIIE group but not for the MICE or CON groups.There was a significant group£time effect for changes in augmentation index at a heart rate of 75 beats/min(F=2.32,p=0.04)with a decrease following for HIIE and MICE but not for CON.For all other measures of central arterial stiffness and hemodynamics,no significant changes were observed(p>0.05).Conclusion:A bout of HIIE appears to lead to a greater transient reduction in central systolic blood pressure than the reduction observed following MICE;however,both HIIE and MICE improved augmentation index at a heart rate of 75 beats/min in people with diabetes.There was no significant difference in response to HIIE and MICE in all outcomes.This provides preliminary evidence on the role of HIIE on such outcomes in people with diabetes.
