Relationship of High Sensitivity C-Reactive Protein with Cardiovascular, Diabetic, and Hepatic Biomarkers

Biomarkers are early predictors of various disorders, circulating level of C-reactive protein is a sensitive biomarker of systemic inflammation and may also be associated with the development of diabetic, hepatic, and cardiovascular diseases. In the present study, we aimed to investigate the association between circulating levels of high sensitive C-reactive protein (hs-CRP) and various biomarkers for hepatic, diabetic, and cardiovascular health. The retrospective analysis included 438 individuals who were tested for these panels simultaneously at Vibrant America Clinical Laboratory. The study population included free-living individuals without any preexisting clinical conditions. Among the cardiovascular markers, a positive correlation and significant association was found between high levels of hs-CRP and serum levels of triglycerides (r = 0.0964, p −0.1423, p −0.1216, p < 0.0105) with circulating levels of hs-CRP. Among all the diabetic markers, glucose (r = 0.1547, p < 0.0011) and glycated serum protein (r = 0.1725, p < 0.0003) were positively correlated with circulating hs-CRP. In the hepatic panel, AST, a transaminase that plays a vital role in amino acid metabolism, was found to have a strong positive correlation with hs-CRP (r = 0.2139, p < 0.0001). In conclusion, the results clearly show the association of hs-CRP with diabetic, hepatic, and cardiovascular risk factors indicating its central value as a key marker for several lifestyle-associated disorders.

High sensitivity C-reactive protein and cardfiac resynchronization therapy in patients with advanced heart failure

Background The data on the prognostic values of high sensitivity C-reactive protein （hsCRP） levels in patients with advanced symp-tomatic heart failure （HF） receiving cardiac resynchronization therapy （CRT） are scarce. The aim of present study was to investigate the association of serum hsCRP levels with left ventricle reverse remodeling after six months of CRT as well as long-term outcome. Methods A total of 232 CRT patients were included. The assessment of hsCRP values, clinical status and echocardiographic data were performed at baseline and after six months of CRT. Long-term follow-up included all-cause mortality and hospitalizations for HF. Results During the mean follow-up periods of 31.3 ± 31.5 months, elevated hsCRP （〉3 mg/L） prior to CRT was associated with a significant 2.39-fold increase （P=0.006） in the risk of death or HF hospitalizations. At 6-month follow-up, patients who responded to CRT showed significant reductions or maintained low in hsCRP levels （–0.5 ± 4.1 mg/L reduction） compared with non-responders （1.7 ± 6.1 mg/L increase, P=0.018）. Com-pared with patients in whom 6-month hsCRP levels were reduced or remained low, patients in whom 6-month hsCRP levels were increased or maintained high experienced a significantly higher risk of subsequent death or HF hospitalizations （Log-rank P〈0.001）. The echocardio-graphic improvement was also better among patients in whom 6-month hsCRP levels were reduced or remained low compared to those in whom 6-month hsCRP levels were raised or maintained high. Conclusions Our findings demonstrated that measurement of baseline and follow-up hsCRP levels may be useful as prognostic markers for timely potential risk stratification and subsequent appropriate treatment strategies in patients with advanced HF undergoing CRT.

Relationship between high sensitivity C-reactive protein and angiographic severity of coronary artery disease

Background Coronary artery disease(CAD)remains a leading cause of morbidity and mortality.Cytokines play a potential role in atherosclerosis pathogenesis and progression.We investigated the association between high sensitive C-reactive protein(hs CRP)and severity of CAD.Methods CAD patients were stratified according to hs CRP cut-off value into high levels hs CRP group(≥8.4 mg/L)and low levels hs CRP group(<8.4 mg/L).Severity of CAD was assessed according to artery stenosis degree and the number of vessel involved.Statistical analysis was performed using Statistical Package for the Social Sciences(SPSS,version 23.0).Results The mean age was 60.3±11.0 years.The level of hs CRP was increased and ranged from 0.2 to 1020.0 mg/L.Biochemical risk factors and severity of CAD didn’t show significant differences between the two groups.In multivariate linear analysis,cardiac troponin I(c Tn I)and serum amyloid A(SAA)were predictors of hs CRP.As shown in receiver operating characteristic(ROC)curve analysis performed in patients with ST-segment elevation myocardial infarction(STEMI)and compared to myonecrosis biomarkers,hs CRP(area under the curve(AUC):0.905;95%CI:0.844-0.966;P<0.001)could be a powerful predictor marker in evaluating the infarct size after myocardial infarction but not better than c Tn I.Conclusions Hs CRP levels were not associated with the severity of CAD but could be useful in the evaluation of myocardial necrosis in patients with STEMI.

High Sensitivity C-Reactive Protein Associated with Different Health Predictors in Middle-Aged and oldest old Chinese

Objective To describe the distribution of plasma high sensitivity C-reactive protein （hsCRP） and explore the relationship between hsCRP and metabolic risk factors among residents living in longevity areas of China. Methods 268 individuals aged between 40 and 59 years and 506 individuals aged over 90 years were selected from 5 longevity areas of China to participate in a cross section longitudinal cohort study. The participants were interviewed with general health related questionnaire to collect their demographic, behavioral and lifestyle data, as well as their chronic conditions, and meanwhile their physical and biomedical parameters including waist circumference （WC）, blood pressure （BP）, hsCRP, plasma lipids, and fasting blood glucose （FBG） were measured. Results The median of hsCRP was 0.99 mg/L in the middle-aged group and 2.76 mg/L in the oldest old group. No significant gender difference was observed between the above two groups. Among the oldest old individuals, 36.56% had an hsCRP level 〉3.0 mg/L. The prevalence of high hsCRP was 26.79% in the middle-aged group. The results of stepwise multiple linear regression analyses showed that HDL-C was independently associated with In （hsCRP） concentration in the middle-aged group, whereas In （TG）, HDL-C and FBG were correlated after adjustment for gender, study site, smoking, drinking, education and BMI in the oldest old group. Conclusion HDL-C is a stronger predictor of elevated hsCRP than other metabolic factors in the middle-aged population. For the oldest old persons, high TG, low HDL-C, and FBG predict elevated plasma hsCRP.

Relationship between coronary atherosclerosis plaque characteristics and high sensitivity C-reactive proteins, interleukin-6

Background The relationship between inflammatory markers and the characteristics of coronary atherosclerosis plaques is uncertain. The aim of the present study was to evaluate the relationship between the characteristics of coronary atherosclerosis plaques and inflammatory markers such as high sensitivity C-reactive proteins （Hs-CRP） and interleukin-6 （IL-6）. Methods All patients suspected of having coronary heart disease （CHD） underwent Siemens 64-slice CT angiography （64-SCTA） to distinguish the quality of plaque of coronary artery lesions. Blood samples were taken to measure levels of serum Hs-CRP and IL-6 in different plaque groups and the control group and compared with the value of 64-SCTA for detection of coronary artery plaque. Results The sensitivity of detecting coronary artery plaque by 64-SCTA was 87.4%, the specificity was 87.1%, the positive predictive value was 82.2%, and the negative predictive value was 91.0%. Comparing the levels of serum Hs-CRP and IL-6 among plaque groups, the mean levels of serum Hs-CRP and IL-6 in three plaque groups were significantly higher than those in the control group （P 〈0.01）. The mean levels of serum Hs-CRP and IL-6 in the soft plaque group and mixed plaque group were significantly higher than those in hard plaque group （P〈0.01）. Plaque burden in the soft plaque group and mixed plaque group was significantly higher than in the hard plaque group （P 〈0.01）, but there was no statistical difference between the soft plaque group and mixed plaque group （P=-0.246）. There was a negative correlation between the CT scale and Hs-CRP and IL-6 levels in the soft plaque group （r= -0.621, P〈0.01, and r= -0.593, P 〈0.01 respectively）. There was a positive correlation between the plaque burden and Hs-CRP and IL-6 levels in the soft plaque group （r=0.579, P〈0.05 and r=0.429, P〈0.05 respectively）. Conclusions 64-SCTA is an effective way to distinguish the different quality of coronary atherosclerosis plaque. Serum Hs-CRP and IL-6 levels can be considered as the indexes to judge the degree of CHD and may reflect the activity of plaque in CHD patients. Thus it is important for clinical diagnosis and risk evaluation of acute coronary syndrome （ACS） patients.

Comparision of high sensitivity C-reactive protein and matrix metalloproteinase 9 in patients with unstable angina between with and without significant coronary artery plaques

Background Inflammation within vulnerable coronary plaques may cause unstable angina by promoting rupture and erosion. C-reactive protein （CRP） is the most reliable and accessible test method for clinical use for identifying coronary artery disease event. Matrix metalloproteinase 9 （MMP-9） is highly over-expressed in the vulnerable regions of a plaque. Our aim was to evaluate the plasma levels of MMP-9 and hsCRP in subjects with both unstable angina and coronary plaques, as well as in those with unstable angina without coronary plaques.

The prognostic role of high-sensitivity C-reactive protein in patients with acute myocardial infarction

1 Introduction Inflammation is one of the main mechanisms in the pathogenesis of atherosclerosis,and the interest to the evaluation of inflammatory biomarkers in coronary artery disease(CAD)has been increasing over the last decade.[1,2]Destabilization of chronic artery plaques,which leads to acute coronary syndromes,has been associated with inflammatory status.[1,3]。

Testosterone replacement therapy improves insulin sensitivity and decreases high sensitivity C-reactive protein levels in hypogonadotropic hypogonadal young male patients

Background Many clinical studies suggest the inverse relationship between testosterone levels and insulin sensitivity in men, however the causative relationship of these two events is still not determined. The purpose of this study was to investigate the effects of testosterone replacement therapy （TRT） on insulin sensitivity, body composition, serum lipid profiles and high sensitivity C-reactive protein （hsCRP） in hypogonadotropic hypogonadal （HH） puberty undeveloped male patients. Methods In this prospectively designed study, we compared homeostasis model assessment of insulin resistance （HOMA-IR）, insulin areas under the curves （AUC） of 3-hour oral glucose tolerance test （OGTT） and other metabolic parameters between 26 HH patients and 26 healthy men. The patients＇ HOMA-IR, insulin AUC, body composition, lipid profiles, hsCRP and other parameters were compared before and after nine-month TRT. Results The average levels of total testosterone （TT） in HH and healthy group were （0.9±0.6） nmol/L and （18.8±3.4） nmol/L, respectively. HOMA-IR in HH group was significantly higher than the healthy group （5.14±5.16 vs 2.00±1.38, P 〈0.005）. Insulin AUC in 3-hour OGTT in HH group was significantly higher than the healthy group （698.6±414.7 vs 414.2±267.5, P 〈0.01）. Fasting glucose level in H H group was significantly higher than control group （（5.1±0.6） mmol/L vs （4.7±0.3） mmol/l, P 〈0.005）. Height, weight and grasp strength of the patients were significantly increased after 9-month TRT. Significant reductions in HOMA-IR （from 5.14±5.16 to 2.97±2.16, P 〈0.01）, insulin AUC （from 698.6±414.7 to 511.7±253.9, P 〈0.01） and hsCRP （from （1.49±1.18） mg/L to （0.70±0.56） mg/L, P 〈0.05） were found after TRT. Serum total cholesterol, LDL-C, HDL-C and triglyceride were all decreased, albeit with no significant difference compared to the level prior to TRT. Conclusions HOMA-IR, insulin AUC and fasting glucose level in HH young male patients were significantly higher than those of the control group, which suggests that low level of testosterone in male adolescents might be a risk factor for insulin resistance. TRT can significantly improve patients＇ insulin sensitivity and suppress serum hsCRP, which in return suggests that TRT may prevent the HH patients from developing diabetes mellitus and cardiovascular diseases （CVD） in future.

Myeloperoxidase and High-Sensitivity C-Reactive Protein for Predicting Major Adverse Cardiovascular Events in Patients with Coronary Heart Disease

Background: Research has shown that high-sensitivity C-reactive protein (hs-CRP) is a major inflammatory marker for prediction of acute coronary syndrome (ACS). Myeloperoxidase (MPO) also plays an important role in atherosclerosis initiation and development. In present study, the major adverse cardiovascular events (MACEs) of patients with coronary heart disease (CHD) were investigated. Methods: MPO, hs-CRP and ACS-related risk factors from 201 ACS (78 AMI and 123 UAP) and 210 non-ACS (84 SAP and 126 non-CHD) patients confirmed by coronary angiography were detected, and the data were analyzed with receiver operating characteristic (ROC) curve and Spearman’s correlation coefficients. MACEs of 285 CHD patients were investigated during the 4-year period follow-up from March 2010 to May 2014. Results: The areas under ROC curve for diagnosing ACS were 0.888 (95% CI 0.843 - 0.933) for MPO, and 0.862 (95% CI 0.815-0.910) for hs-CRP, respectively. There were significantly correlations between MPO and hs-CRP in both ACS and non-ACS groups. Regarding to ACS patients, both MPO and hs-CRP were positively correlated with BMI, TC, TG, LDL-C and Hcy. Prospective study demonstrated that the incidences of MACEs associated significantly with elevated MPO baseline level (yes vs no, OR 7.383, 95% CI 4.095 - 13.309) and high hs-CRP baseline level (yes vs no, OR 4.186, 95% CI 2.469 - 7.097) in CHD patients. Conclusions: The present study provides the epidemiological evidence that elevated baseline MPO and hs-CRP levels are both valuable predictors of MACEs in CHD patients. MPO and hs-CRP would prompt the progression of atherosclerosis and development from SAP to ACS.

Responses of serum inflammatory factor high-sensitivity C-reactive protein, interleukin-6, and tumor necrosis factor-alpha in elderly males with cerebral infarction Non-randomized concurrent control

BACKGROUND： Cerebral infarction is poorly treated due to neuronal necrosis and secondary pathophysiological changes; for example, free radical production and inflammatory reactions. OBJECTIVE： To detect the levels of high-sensitivity C-reactive protein （hs-CRP）, interleukin-6 （IL-6）, and tumor necrosis factor- a （TNF- α ） in elderly males with cerebral infarction. DESIGN： Non-randomized current control study. SETTING： Cadre Medical Department, Guizhou Provincial People＇s Hospital. PARTICIPANTS： Forty elderly males （65-89 years old） with cerebral infarction were selected from Cadre Medical Department, Guizhou Provincial People＇s Hospital from February 2004 to December 2006. All patients met the diagnostic criteria of cerebral infarction modified at the 4th National Cerebrovascular Disease Academic Meeting, and were diagnosed on the basis of CT or MRI tests. Furthermore, 35 elderly male inpatients （65-87 years old） without cerebral infarction were selected as the control group. Included subjects provided confirmed consent and did not have heart disease, diabetes mellitus, lipid disorder, acute trauma, infection, rheumatism, or other inflammatory diseases. The study was approved by the local ethics committee. There were no significant differences in age, blood pressure, and lipid levels between the cerebral infarction group and the control group （P 〉 0.05）, and this suggested that the baseline data of both groups were comparable. METHODS： Fasting venous blood was drawn from cerebral infarction patients 24 hours after cerebral infarction attack and from control subjects 24 hours after hospitalization. A latex-enhanced immunoturbidimetric assay and an enzyme-linked immunosorbent assay were used to detect the levels of hs-CRP, IL-6, and TNF- α in the serum. MAIN OUTCOME MEASURES： The levels of hs-CRP, 1L-6, and TNF- α in the serum in both groups. RESULTS： Forty cerebral infarction patients and thirty-five control subjects were included in the final analysis without any loss. Levels of hs-CRP, IL-6, and TNF-α in the cerebral infarction group were significantly higher than those in the control group （P 〈 0.01 ）. CONCLUSION： Levels of serum inflammatory reactive factors are increased in elderly males with cerebral infarction.

Correlation of Enhancement Degree on Contrast-enhanced Ultrasound with Histopathology of Carotid Plaques and Serum High Sensitive C-Reactive Protein Levels in Patients Undergoing Carotid Endarterectomy

This study was undertaken to investigate the correlation of the enhancement degree on contrast-enhanced ultrasound(CEUS) with the histopathology of carotid plaques and the serum high sensitive C-reactive protein(hs-CRP) levels in patients undergoing carotid endarterectomy(CEA). Carotid CEUS was performed preoperatively in 115 patients who would undergo CEA, and the enhancement degree of the carotid plaques was evaluated by both the visual semiquantitative analysis and the quantitative time-intensity curve analysis. Serum hs-CRP levels were detected using the particle-enhanced immunoturbidimetric assay also before the operation. Additionally, the carotid plaque samples were subjected to histopathological examination postoperatively. The density of neovessels and the number of macrophages in the plaques were assessed by immunohistochemistry. The results showed that among the 115 patients, grade 0 plaque contrast enhancement was noted in 35 patients, grade 1 in 48 patients and grade 2 in 32 patients. The degree of plaque enhancement, the density of neovessels, the number of macrophages, and the hs-CRP levels were highest in the grade 2 patients. Correlation analysis showed that the enhancement degree of the carotid plaques was closely related to the immunohistochemical parameters of the plaques and the serum hs-CRP levels. It was suggested that the carotid plaque enhancement on CEUS can be used to evaluate the vulnerability of carotid plaques.

EFFECTS OF SIMVASTAIN COMBINED WITH OMEGA-3 FATTY ACIDS ON HIGH SENSITIVE C-REACTIVE PROTEIN, LIPIDEMIA, ANDFIBRINOLYSIS IN PATIENTS WITH MIXED DYSLIPIDEMIA

Objective To evaluate the effects of simvastatin combined with omega-3 fatty acids on high sensitive C-reactive protein(HsCRP), lipidemia, and fibrinolysis in coronary heart disease (CHD) and CHD risk equivalent patients with mixed dyslipi-demia. Methods A randomized, double-blind placebo controlled and parallel group trial was conducted. Patients with CHD and CHD risk equivalents with mixed dyslipidemia were treated with 10 or 20 mg simvastatin for 6-12 weeks. Following with the treatment of patients whose low-density lipoprotein cholesterol (LDL-ch) reaching goal level (< 100 mg/dL) or close to the goal (< 130 mg/dL), while triglyceride (TG) ≥200 mg/dL and < 500 mg/dL, was combined with omega-3 fatty acids (3 g/d) or a placebo for 2 months. The effects of the treatment on HsCRP, total cholesterol (TC), LDL-ch, high-density lipoprotein cholesterol (HDL-ch), TG, lipoprotein (a) [LP (a)], apolipoprotein A1 (apoA1), apolipoprotein B (apoB), plasminogen activator inhibitor-1 (PAI-1), and tissue plasminogen activator (tPA) were investigated. Forty patients finished the study with each group consisting of twenty patients. Results (1) There were significant reductions of HsCRP, TG, TC, and TC/HDL-ch, which decreased by 2.16 ±2.77 mg/L (38.5%), 94.0 ±65.4 mg/dL (31.1%), 13.3 ±22.3 mg/dL (6.3%), 0.78 ±1.60 respectively in the omega-3 fatty acids group (P< 0.01, < 0.001, < 0.05, < 0.05) compared to the baseline. HsCRP and triglyceride reduction were more significant in omega-3 fatty acids group compared to the placebo group (P=0.021 and 0.011 respectively). (2) In the omega-3 fatty acids group, the values and percentage of TG reduction had a significantly positive relation with HsCRP reduction (r=0.51 and 0.45, P=0.021 and 0.047 respectively). Conclusion In CHD and CHD risk equivalent patients with mixed dyslipidemia, dyslipidemia’s therapeutic effect using simvastatin and omega-3 fatty acids may result from not only the combination of lipid adjustment, but also enhancement of their own nonlipid influences.

Combined effects of serum C-reactive protein and A Body Shape Index(ABSI)on ischemic stroke incidence among Inner Mongolians in China

Objective We aimed to evaluate the combined effect of high serum C-reactive protein (CRP) and high A Body Shape Index (ABSI) on ischemic stroke incidence in an Inner Mongolian population in China.Methods A prospective cohort study was conducted among 2,589 participants from June 2002 to July 2012 in Inner Mongolia, China.

ASSOCIATION OF INSULIN RESISTANCE AND C-REACTIVE PROTEIN WITH CORONARY ARTERY DISEASE IN PATIENTS WITH NORMAL GLUCOSE TOLERANCE

Objective To examine insulin resistance and high sensitivity C-reactive protein （hsCRP） association with clinical and angiographic severity of coronary artery disease （CAD） in patients with normal glucose tolerance. Methods In 638 consecutive patients with normal glucose tolerance, 221 had atypical chest pain and normal coronary artery （control group）, 279 had stable angina and CAD （SAP group ）, and 138 suffered acute myocardial infarction （ MI group）. The degree of CAD was further divided into borderline lesion （ lumen diameter narrowing 50% - 69% ）, significant 1-, 2- or 3-vessel disease （ luminal diameter narrowing 〉I 70% ）. Fasting serum glucose, insulin and hsCRP levels and lipid profiles were measured, and homeostasis model assessment for insulin resistance （ HOMA-IR ） was calculated. Multivariate analysis was performed to assess risk factors for 3-vessel disease or acute MI. Results Serum hsCRP, lipoprotein （a） levels, and insulin resistance index （IRI） were higher in AMI group than those in SAP and control groups. Serum hsCRP level and IRI were also higher in 3-vessel disease than those in other groups. Multivariate regression analysis revealed that insulin resistance, cigarette smoking, serum hsCRP, and lipoprotein （a） levels were independent risk factors for acute MI. Lipoprotein （ a ） elevation was an independent risk factor for 3-vessel disease. Conclusion Insulin resistance and high serum hsCRP level were associated with occurrence of acute MI and angiographic severity of coronary disease in patients with normal glucose tolerance.

Clinical application of neutrophil/lymphocyte ratio combined with high sensitive C reactive protein in evaluation of community acquired pneumonia

Objective:To explore the application value of neutrophil/lymphocyte ratio (NLR) combined with high sensitive C reactive protein (hs-CRP) in the evaluation of community acquired pneumonia (CAP). Methods:From November 2015 to October 2016, 58 cases of CAP patients admitted in our department were selected as research objects and were divided into low risk group and high risk group according to the PSI score and CURB-65 standard for evaluation. They were divided into improved group (48 cases) and death group (10 cases) according to prognosis. Hs-CRP was determined by immunoturbidimetric assay, procalcitonin (PCT) by immunofluorescence, NLR by count method of laser scattering, and white blood (WBC) was counted. The differences in WBC, PCT, NLR and hs-CRP between different risk groups were compared, and the correlation was evaluated using Spearman's rank correlation analysis method. The changes in indexes were observed in the improved and death cases. Results:The high risk group had higher NLR, PCT and hs-CRP than low risk group (P<0.05), while no significant difference was found in WBC (P>0.05). No correlation was found between NLR and WBC, while a strong correlation was found between hs-CRP and PCT. The WBC, PCT, NLR and hs-CRP levels were significantly lower in the improved group than the death group (P<0.05). Conclusions:NLR combined with hs-CRP, WBC, and PCT has a good assessment of the severity of CAR, and high levels of NLR, hs-CRP, WBC, and PCT predict the severity of the disease and poor prognosis.

Associations of plasma homocysteine and high-sensitivity C-reactive protein levels with arterial stiffness in Chinese population： a community-based study

Background Arterial stiffness increases with age and is also associated with traditional cardiovascular risk factors. Little is known about the relations of homocysteine and high-sensitivity C-reactive protein （hs-CRP） to arterial stiffness in the Chinese community. The aim of the present study was to investigate the association of plasma homocysteine and hs-CRP levels with arterial stiffness in a community-based cohort. Methods We related levels of homocysteine and hs-CRP to four measures of arterial stiffness （carotid-femoral pulse wave velocity （PWV）, carotid-radial PWV, carotid-ankle PWV and heart rate corrected augmentation index） in 1680 participants from two communities of Beijing, China. Arterial stiffness was measured within two days of the time of biomarker measurement. Results In univariate analysis, homocysteine was positively associated with the carotid-femoral PWV （r=0.211, P 〈0.0001）, carotid-radial PWV （r=0.120, P 〈0.0001） and carotid-ankle PWV （r=0.148, P 〈0.0001）, whereas it was inversely related to the augmentation index （r= -0.052, P=0.016）. Hs-CRP was positively associated with the carotid-femoral PWV （r=0.074, P=0.001） and carotid-ankle PWV （r=0.050, P=0.02）. In multiple-adjusted models （R2=0.57）, homocysteine levels remained a significant determinant of the carotid-femoral PWV （standardized 13=0.065, P=0.007）, whereas the association of hs-CRP with measurements of arterial stiffness was not present. Conclusions In the Chinese population, plasma homocysteine levels are associated with alterations of aortic stiffness, whereas plasma levels of hs-CRP are not independently related to artery stiffening.

冠心病患者PCI术后认知功能改变的相关研究

目的观察经皮冠状动脉介入治疗(PCI)和冠状动脉造影(CAG)对冠状动脉粥样硬化性心脏病(冠心病)患者围术期认知功能的影响,并探讨相应临床化验指标与认知功能障碍的相关性。方法连续收集于北京安贞医院心内科住院治疗的冠心病患者203例为研究对象,其中接受冠状动脉(冠脉)造影55例(CAG组),接受冠脉支架植入治疗148例(PCI组)。于术前及术后6 h,通过“基本认知能力测验”(BCAT)软件系统分别对两组患者术前及术后的加工速度、工作记忆及情景记忆进行检测,同时提取患者术前的相关实验室检查及手术相应临床指标。采用Wilcoxon符号秩检验比较患者的术前及术后认知功能评分的差异,采用皮尔逊相关系数评估各项实验室检查指标及临床指标与术后加工速度、工作记忆及情景记忆得分的相关性,采用多元线性回归评估各检查指标对于术后加工速度、工作记忆及情景记忆得分的影响。结果CAG组患者术前、术后各项认知功能评分均无显著性差异,而PCI组患者在加工速度、情景记忆两个维度上,术后的认知功能评分高于术前评分(P<0.05),在工作记忆维度上无显著性差异(P>0.05)。相关分析表明PCI组患者的年龄与术后工作记忆得分有显著负相关关系(r=-0.258,P<0.01),手术用时与术后情景记忆得分有显著负相关关系(r=-0.206,P<0.05),血清超敏C反应蛋白(hs-CRP)与术后加工速度得分有显著负相关关系(r=-0.273,P<0.01),血清同型半胱氨酸(Hcy)与术前和术后加工速度得分有显著负相关关系(r=-0.288,P<0.01),血清游离三碘甲状腺原氨酸(FT3)与术后情景记忆得分有显著正相关关系(r=0.296,P<0.01)。多元线性回归结果显示,年龄是PCI组患者术后工作记忆得分的独立危险因素(β=-0.238,P<0.05),hs-CRP和Hcy是PCI组患者术后加工速度得分的独立危险因素(β=-0.218~-0.207,P<0.05),FT3是PCI组患者术后情景记忆得分的独立保护因素(β=0.224,P<0.05)。结论冠心病患者接受PCI治疗可加重患者围术期认知功能障碍,应在术前注意筛查患者的认知功能状况并及时进行干预。年龄、手术时间、血清hs-CRP和Hcy水平的增高以及FT3水平的降低是PCI手术患者术后认知功能减低的重要影响因素,血清hs-CRP、Hcy及FT3水平对冠脉介入治疗术后认知功能障碍可能具有早期预测作用。
