Case Re...Background: Misdiagnosis of angina pectoris is not uncommon in athletes. Physicians can fail to make a correct clinical diagnosis if they don’t have the skills and experience needed to recognize this disease. Case Report: This case report describes an exertional angina misdiagnosis due to a severe coronary artery disease in a 50-year-old male athlete initially examined by both a general practitioner and a cardiologist. The athlete subsequently underwent physical examination in a sports cardiology medicine center where diagnosis of angina pectoris caused by severe mono-vessel coronary artery disease was made, requiring an angioplasty with stenting. Conclusions: Although most of the severe symptoms in a heart attack are hard to miss, sometimes in athletes angina pectoris is not readily recognized. However, this is dangerous and can lead to the sudden death of the athlete. Diagnosis must be timely and accurate, in order for the patient to receive the best prognosis.展开更多

The aim of this study was the investigation of association between nonalcoholic fatty liver disease (NAFLD) and coronary artery disease (CAD) in patients with angina pectoris. Methods: 82 patients with confirmed CAD by coronary angiography and 82 individuals with normal coronary angiography, as the control group, were selected. Hepatic ultrasound scanning was performed in all the subjects to determinate the NAFLD. Data were analyzed by SPSS software and independent T-test and Chi-square tests. Results: Findings gathered from the patients with angina pectoris showed that the prevalence of NAFLD in CAD patients was higher than the control group. Grade of fatty liver and the portal vein size in CAD patients were significantly more than the control group. Conclusion: NAFLD is a risk factor of CAD in the angina pectoris patients. Increase in the prevalence of NAFLD can lead to the increase in cardiovascular diseases.展开更多

Methods: Fifty-four patients with UAP were equally assigned into two groups, the treated group and the control group, both treated with conventional Western medicine, but with GLE given additionally to the treated group. Blood of all patients was taken before and 4 weeks after treatment to prepare the peripheral mononuclear cells, then which were incubated in the completed medium containing granulocyte-macrophage colony stimulatory factor (GMCSF) and interleukin-4 (IL-4) to induce mature DO. The expression of co-stimulating factor CD86 (B7-2) on the surface of DC was detected by flow cytometry, and the stimulating capacity of DC was determined by mixed lymphocyte reaction (MLR). The blood levels of cytokines, interferon-γ (IFN-γ), and IL-4, were analyzed by ELISA, and blood C-reactive protein (CRP) level by turbidimetry. Moreover, the direct effect of Ginkgolide B on CD86 expression on DO were also tested in vitro. Results: After treatment, CD86 expression on DO, the stimulating capacity of DO as well as levels of IFN-γ and ORP were lowered in both groups (P〈0.05 or P〈0.01), but the changes were much more significant in the treated group than those in the control group. Ginkgolide B showed a direct inhibitory effect on the CD86 expression on DO. Conclusion: The inhibition of GLE on DO and thereby the suppression on inflammatory reaction may be one of the mechanisms of GLE in treating patients with UAP.展开更多

Methods We measuredtissure- type plasminogen activator (t- PA) activity and plasminogen activator inhibitor 1(PAI- 1) activitybefore and after treadmill exercise test in 20 healthy subjects and 25 patients with UAP. ResultsResting t - PA activities were similar between two groups, but resting PAI- 1 activity was higher in UAP groupthan in control. Although both groups showed significant increase in t- PA activity with exercise, post - exerciset - PA activity was significantly lower in patients with UAP than in control (0.96± 0.45IU/ml vs 1.89± 0.68I U/ml,P<0.01), Post - exercise PAI- 1 activity was still much higher in UAP group than in control (8.20±2.28A U/ml vs4.21± 0.68A U/ml, P<0.01). Conclusion There existed impaired fibrinolysis in patients with UAP not only at restbut also alter exercise loading.展开更多

Methods: Sixty patients with diagnosis of CHD-UAP confirmed and differentiated to be Qi-deficiency and blood stasis by TCM were randomly divided into two groups and treated, on the basis of Western drug-therapy, with Tongxinluo capsule (通心络胶囊, TXL) and Huoxue Tongmai capsule (活血通脉胶囊, HXTM) respectively by way of oral taking three times a day, 3 capsules every time, with 1 month as one therapeutic course. The number of CEC in patients' blood circulation was counted before and after treatment. Besides, the number of CEC in 30 healthy persons was also counted for control. Results: The number of CEC in CHD-UAP patients was significantly higher than that in the healthy persons (P<0.01). After the patients were treated with CH, either TXL or HXTM, it significantly decreased (P<0.01)with insignificant difference between the two treated groups. Conclusion: CEC in CHD-UAP patients is severely damaged and endothelial function in disorder, Chinese herbs have protective effect on patients' CEC.展开更多

Methods: One hundred and twenty old in-patients of coronary heart disease with UA were randomly divided into two groups. The 60 patients in the treated group were treated with oral administration of enteric soluble 50 mg Asp once a day and GDI 20 ml per day by intravenous dripping, with 14 days as one therapeutic course, while the other 60 in the control group were treated with enteric soluble Asp 100 mg alone once a day orally. Besides, isosorbide-5-mononitrate 20 mg twice a day was applied to both groups, and the β-ad-renoceptor blocker, blood lipids regulatory agents and nitroglycerin (10 mg by intravenous dripping) were given accordingly. The angina total improving rate, hemorrheologic indexes (whole blood viscosity, plasma viscosity, fibrinogen, platelet aggregation rate), comprehensive clinical terminal event and the total occurrence rate of adverse reaction in the two groups were observed. Results: After treatment, comparison between the two groups showed insignificant difference in aspects of angina total improving rate (75.00% vs 65.00%), hemorrheological indexes and comprehensive clinical terminal event rate (25.00% vs 31.67%), P>0.05, and the hemorrheological indexes were improved in both groups (P<0.05), but the total occurrence rate of adverse reaction in the treated group was lower than that in the control group (6. 67% vs 25.00%), showing significant difference (P<0.05). Conclusion: In treatment of senile UA, small dose of Asp combined with GDI showed therapeutic effect similar to that of conventional dose of Asp, but it has lower adverse reaction.展开更多

Methods: Collagen type Ⅰ-induced platelet aggregation was measured in 33 healthy subjects in vitro. Plasma level of α-granule membrane protein (GMP-140) was measured in both the above 33 healthy subjects during fasting and 35 patients with recent onset effort anina during rest onset within 24 h after hospitalization. Furthermore, the platelet membrane GP Ⅰa gene 807C/T polymorphism was checked in all subjects with polymerase chain reaction-sequence specific primers(PCR-SSP) technique. Results: The lag time before 30% platelet aggregation was significantly longer in healthy subjects with CC genotype than with TC genotype (P<0.01). However, there was no significant difference in the maximal platelet aggregation between healthy subjects with the above two genotypes. Plasma level of GMP-140 was significantly higher in TC genotypic patients with recent onset effort angina than in CC genotypic patients with the same type of UAP(P<0.05) and healthy subjects (P<0.01), furthermore, there was also significant difference between the latter two groups(P<0.05). Conclusion: The rapid initiation of collagen-induced platelet aggregation may be associated with platelet membrane GP Ⅰa T (807) allele, which may play an important role in the pathogenesis of UAP.展开更多

文摘Background: Misdiagnosis of angina pectoris is not uncommon in athletes. Physicians can fail to make a correct clinical diagnosis if they don’t have the skills and experience needed to recognize this disease. Case Report: This case report describes an exertional angina misdiagnosis due to a severe coronary artery disease in a 50-year-old male athlete initially examined by both a general practitioner and a cardiologist. The athlete subsequently underwent physical examination in a sports cardiology medicine center where diagnosis of angina pectoris caused by severe mono-vessel coronary artery disease was made, requiring an angioplasty with stenting. Conclusions: Although most of the severe symptoms in a heart attack are hard to miss, sometimes in athletes angina pectoris is not readily recognized. However, this is dangerous and can lead to the sudden death of the athlete. Diagnosis must be timely and accurate, in order for the patient to receive the best prognosis.
文摘Background: Prevalence of nonalcoholic fatty liver disease (NAFLD) is increasing in Iranian population. The aim of this study was the investigation of association between nonalcoholic fatty liver disease (NAFLD) and coronary artery disease (CAD) in patients with angina pectoris. Methods: 82 patients with confirmed CAD by coronary angiography and 82 individuals with normal coronary angiography, as the control group, were selected. Hepatic ultrasound scanning was performed in all the subjects to determinate the NAFLD. Data were analyzed by SPSS software and independent T-test and Chi-square tests. Results: Findings gathered from the patients with angina pectoris showed that the prevalence of NAFLD in CAD patients was higher than the control group. Grade of fatty liver and the portal vein size in CAD patients were significantly more than the control group. Conclusion: NAFLD is a risk factor of CAD in the angina pectoris patients. Increase in the prevalence of NAFLD can lead to the increase in cardiovascular diseases.
文摘Objective: To investigate the effects of Ginkgo leaf extract (GLE) on function of dendritic cells (DO) and Th1/Th2 cytokines in patients with unstable angina pectoris(UAP). Methods: Fifty-four patients with UAP were equally assigned into two groups, the treated group and the control group, both treated with conventional Western medicine, but with GLE given additionally to the treated group. Blood of all patients was taken before and 4 weeks after treatment to prepare the peripheral mononuclear cells, then which were incubated in the completed medium containing granulocyte-macrophage colony stimulatory factor (GMCSF) and interleukin-4 (IL-4) to induce mature DO. The expression of co-stimulating factor CD86 (B7-2) on the surface of DC was detected by flow cytometry, and the stimulating capacity of DC was determined by mixed lymphocyte reaction (MLR). The blood levels of cytokines, interferon-γ (IFN-γ), and IL-4, were analyzed by ELISA, and blood C-reactive protein (CRP) level by turbidimetry. Moreover, the direct effect of Ginkgolide B on CD86 expression on DO were also tested in vitro. Results: After treatment, CD86 expression on DO, the stimulating capacity of DO as well as levels of IFN-γ and ORP were lowered in both groups (P〈0.05 or P〈0.01), but the changes were much more significant in the treated group than those in the control group. Ginkgolide B showed a direct inhibitory effect on the CD86 expression on DO. Conclusion: The inhibition of GLE on DO and thereby the suppression on inflammatory reaction may be one of the mechanisms of GLE in treating patients with UAP.
文摘In order to inquire into the therapeutic effects of Xiao Shi Xiong Huang San (硝石雄黄散the Nitrum and Realgar Powder), one of the Dunhuang Prescription, on angina pectoris due to coronary heart disease (APCHD), the authors have treated 61 cases of APCHD by externally applying paste of the powder on Zhiyang (GV 9), with another 30 cases of APCHD treated with the nitroglycerin paste on Zhiyang as the controls. The results showed that the total effective rate was 82% and markedly effective rate 31.2% in the treatment group (the Paste of Nitrum and Realgar Powder), and the total effective rate was 46.6% and markedly effective rate 23.2% in the control group (the nitroglycerin paste). The difference in therapeutic effects between the two groups was very significant (P<0.01), indicating that the therapeutic effect of the former was significantly superior to that of the latter.
文摘Objective:To explore the effect of Guhong injection combined with atorvastatin on CHD patients with angina pectoris and its influence on hemorheology and oxidative stress.Methods:80 CHD patients with angina pectoris admitted to our hospital from December 2018 to December 2019 were randomly divided into the observation group(40 cases)and the control group(40 cases)by use of the random number table.The patients in the control group were treated with atorvastatin,while those in the observation group were treated with Guhong injection on the basis of the control group.The course of treatment was 2 weeks for each group.The treatment effect,the frequency of angina pectoris seizure and its duration before and after treatment,the changes of hemorheology indexes and oxidative stress and the occurrence of adverse reactions were compared between the two groups.Results:the total effective rate of the observation group(92.50%)was higher than that of the control group(70.00%)(p<.05).The frequency of angina pectoris seizure and its duration in these two groups after treatment were lower than those before treatment(Observation group:t=25.588,23.009;Control group:t=16.587,16.263;p<.05);After treatment,the frequency of angina pectoris seizure and its duration in the observation group were lower than those in the control group(t=15.191,9.425;p<.05).In the observation group,the hemorheology indexes after treatment were lower than those before treatment(t=6.742,15.224,6.983,23.537,p<.05);the hemorheology indexes after treatment in the observation group were lower than those in the control group(t=5.201,13.913,5.539,13.745;p<.05).In the observation group,the level of serum SOD after treatment was higher than that before treatment,while the levels of LPO and MDA after treatment were lower than those before treatment(t=10.839,6.924,8.466;p<.05);the level of serum SOD after treatment in the observation group was higher than that in the control group,while the levels of LPO and MDA after treatment in the observation group were lower than those in the control group(t=6.171,6.432,5.394;p<.05).The incidence of adverse reactions in the observation group was lower than that in the control group(p<.05).Conclusions:Guhong injection combined with atorvastatin has an obvious clinical effect on CHD patients with angina pectoris,and it can improve hemorheology indexes and oxidative stress reaction with fewer adverse reactions.
文摘Objective To examine if the skin microvascular bed is altered and can be modified by enhanced external counterpulsation(EECP)in patients with chronic refractory angina.Methods Twenty patients diagnosed with refractory angina were divided into EECP(n=10)or no EECP(n=10)groups.The data were compared to matched healthy subjects(n=20).The cutaneous forearm microvascular blood flow was measured by Laser-Doppler flowmetry.The vascular responsiveness to iontophoretic administration of acetylcholine(ACh),sodium nitroprusside(SNP)and local skin warming were studied.Measurements of Canadian Cardiovascular Society(CCS)-class,blood pressure and plasma samples were registered.Results EECP patients showed reduced CCS-class compared to no EECP(P<0.05).Both EECP and no EECP(P<0.05)groups had decreased systolic blood pressure(SBP)as compared to SBP at baseline(P<0.05).There was no difference in resting blood flow between the two refractory groups at baseline as well as after EECP and seven weeks of follow-up.Responses to heating,the responses to ACh and SNP in the cutaneous microcirculation were lower in both groups of refractory angina patients as compared to healthy subjects(P<0.05).EECP patients corresponded positively to the treatment shown by reduced plasma level of soluble interleukin-2 receptor and CCS-class.Conclusions Refractory angina patients have reduced responsiveness in their cutaneous microcirculation to ACh,SNP and heat compared to healthy subjects.Although EECP reduced the CCS-class,this effect was not associated with improvements in responsiveness of the cutaneous microcirculation.
文摘Objective The purpose of this study was to evaluate the fibrinolytic response to exercise in patients with unstable angina pectoris(UAP) compared with an age - matched control group. Methods We measuredtissure- type plasminogen activator (t- PA) activity and plasminogen activator inhibitor 1(PAI- 1) activitybefore and after treadmill exercise test in 20 healthy subjects and 25 patients with UAP. ResultsResting t - PA activities were similar between two groups, but resting PAI- 1 activity was higher in UAP groupthan in control. Although both groups showed significant increase in t- PA activity with exercise, post - exerciset - PA activity was significantly lower in patients with UAP than in control (0.96± 0.45IU/ml vs 1.89± 0.68I U/ml,P<0.01), Post - exercise PAI- 1 activity was still much higher in UAP group than in control (8.20±2.28A U/ml vs4.21± 0.68A U/ml, P<0.01). Conclusion There existed impaired fibrinolysis in patients with UAP not only at restbut also alter exercise loading.
文摘Objective: To observe the effect and clinical significance of circulating endothelial cells (CEC) in the pathogenesis of coronary heart disease with unstable angina pectoris (CHD-UAP), and to explore the protective effect of Chinese herbs for activating blood circulation, removing stasis and supplementing Qi (CH) on CHD-UAP patient's CEC. Methods: Sixty patients with diagnosis of CHD-UAP confirmed and differentiated to be Qi-deficiency and blood stasis by TCM were randomly divided into two groups and treated, on the basis of Western drug-therapy, with Tongxinluo capsule (通心络胶囊, TXL) and Huoxue Tongmai capsule (活血通脉胶囊, HXTM) respectively by way of oral taking three times a day, 3 capsules every time, with 1 month as one therapeutic course. The number of CEC in patients' blood circulation was counted before and after treatment. Besides, the number of CEC in 30 healthy persons was also counted for control. Results: The number of CEC in CHD-UAP patients was significantly higher than that in the healthy persons (P<0.01). After the patients were treated with CH, either TXL or HXTM, it significantly decreased (P<0.01)with insignificant difference between the two treated groups. Conclusion: CEC in CHD-UAP patients is severely damaged and endothelial function in disorder, Chinese herbs have protective effect on patients' CEC.
文摘Objective: To evaluate the therapeutic and adverse effect of small dose of aspirin (Asp) combined with Ginkgo-damole injection (GDI,银杏达莫注射液) in treating senile unstable angina pectoris (UA). Methods: One hundred and twenty old in-patients of coronary heart disease with UA were randomly divided into two groups. The 60 patients in the treated group were treated with oral administration of enteric soluble 50 mg Asp once a day and GDI 20 ml per day by intravenous dripping, with 14 days as one therapeutic course, while the other 60 in the control group were treated with enteric soluble Asp 100 mg alone once a day orally. Besides, isosorbide-5-mononitrate 20 mg twice a day was applied to both groups, and the β-ad-renoceptor blocker, blood lipids regulatory agents and nitroglycerin (10 mg by intravenous dripping) were given accordingly. The angina total improving rate, hemorrheologic indexes (whole blood viscosity, plasma viscosity, fibrinogen, platelet aggregation rate), comprehensive clinical terminal event and the total occurrence rate of adverse reaction in the two groups were observed. Results: After treatment, comparison between the two groups showed insignificant difference in aspects of angina total improving rate (75.00% vs 65.00%), hemorrheological indexes and comprehensive clinical terminal event rate (25.00% vs 31.67%), P>0.05, and the hemorrheological indexes were improved in both groups (P<0.05), but the total occurrence rate of adverse reaction in the treated group was lower than that in the control group (6. 67% vs 25.00%), showing significant difference (P<0.05). Conclusion: In treatment of senile UA, small dose of Asp combined with GDI showed therapeutic effect similar to that of conventional dose of Asp, but it has lower adverse reaction.
文摘BACKGROUND Solitary plasmacytoma in the left rib is rare and can cause chest discomfort such as chest pain and tightness,and its clinical manifestations are not typical,so it is often misdiagnosed.We report a case of left costal plasmacytoma misdiagnosed as angina pectoris.We also review the literature and provide suggestions as to how to avoid misdiagnosis.CASE SUMMARY A 77-year-old man with a history of intermittent chest tightness for 3 years presented with pain in the left chest for 1 wk and was admitted to hospital.The cardiologists initially diagnosed angina pectoris but the findings of coronary angiography were not consistent with the symptoms.Computed tomography showed that the left eighth rib mass was accompanied by bone destruction.The patient was transferred to our department for further treatment.Preoperative biopsy indicated that the lesion was possibly malignant,and elective surgery was performed to remove the lesion.The size of the tumor was about 4 cm.The tumor was spindle-shaped and protruded into the pleural cavity,without invading the lungs.Postoperative pathology confirmed that the left rib lesion was plasmacytoma.After 14 mo follow-up,the patient died of systemic metastasis.CONCLUSION Left rib solitary plasmacytoma is a rare disease confined to a specific rib and can cause local pain.Attention should be paid to the differential diagnosis of angina pectoris to avoid misdiagnosis.
文摘Objective: To investigate the effect of platelet membrane glycoprotein(GP) Ⅰa gene polymorphism in the pathogenesis of unstable angina pectoris (UAP) in Chinese people. Methods: Collagen type Ⅰ-induced platelet aggregation was measured in 33 healthy subjects in vitro. Plasma level of α-granule membrane protein (GMP-140) was measured in both the above 33 healthy subjects during fasting and 35 patients with recent onset effort anina during rest onset within 24 h after hospitalization. Furthermore, the platelet membrane GP Ⅰa gene 807C/T polymorphism was checked in all subjects with polymerase chain reaction-sequence specific primers(PCR-SSP) technique. Results: The lag time before 30% platelet aggregation was significantly longer in healthy subjects with CC genotype than with TC genotype (P<0.01). However, there was no significant difference in the maximal platelet aggregation between healthy subjects with the above two genotypes. Plasma level of GMP-140 was significantly higher in TC genotypic patients with recent onset effort angina than in CC genotypic patients with the same type of UAP(P<0.05) and healthy subjects (P<0.01), furthermore, there was also significant difference between the latter two groups(P<0.05). Conclusion: The rapid initiation of collagen-induced platelet aggregation may be associated with platelet membrane GP Ⅰa T (807) allele, which may play an important role in the pathogenesis of UAP.

文摘Objective:Shengmai injection is a commonly used traditional Chinese medicine for the treatment of angina pectoris.However,there is still a lack of high-quality clinical research evidence for the treatment effect of Shengmai injection for angina pectoris.Real-world studies based on large samples can provide Shengmai injection.Researches on the treatment of angina pectoris with Shengmai injection provide important evidence.Methods:This article is based on the information collected by the hospital information system(HIS)database of 22 tertiary A general hospitals for all patients who used Shengmai injection and those who did not use Shengmai injection.The propensity scoring method was used to evaluate the possible existence of the research data.The confounding factors are controlled.Through the general Logistic regression analysis method,the propensity score weighted Logistic regression analysis method and the propensity score weighted Logistic regression analysis method with covariates,the therapeutic effect of Shengmai injection on angina pectoris was explored.Results:Three kinds of logistic regression analysis showed that there were statistical differences in the treatment effect of Shengmai injection on angina pectoris in the group without Shengmai injection.Propensity score weighted logistic regression analysis with covariates balanced the effect of multiple confounding factors.Using real-world data to construct a retrospective cohort study confirmed the clinical effectiveness of Shengmai injection in the treatment of angina pectoris,and at the same time confirmed the wide application of Shengmai injection in angina pectoris complicated with multiple organ failure.Conclusion:Shengmai injection is effective in the treatment of angina pectoris.The weighted method of propensity score removes confounding factors,which improves the reliability of real-world research results.

文摘Objective:To evaluate the efficacy and safety of Xuesaitong Injection in the treatment of angina pectoris.Methods:CNKI and WAN were retrieved Fang,VIP,CBMdisc,PubMed and Cochrane libraries published a randomized controlled trial of Xuesaitong Injection in the treatment of angina pectoris of coronary heart disease from the beginning of the establishment of the database to January 2020.29 cases were finally included in the study through layer by layer selection.The total sample size was 2560 cases,including 1307 cases in the experimental group and 1253 cases in the control group.The data collected were meta analyzed by Revman 5.3 software.Results:on the basis of routine western medicine treatment,Xuesaitong injection was added in the clinical comprehensive effective rate([RR=1.31;95%CI(1.25,1.39)]),angina symptom improvement rate([RR=1.16;95%CI(1.07,1.26)]),ECG improvement rate([RR=1.25;95%CI(1.14,1.38)]),angina attack times([RR=-2.49;95%CI(-3.27,-1.70)]);fibrinogen([MD=-0.61;95%CI(-0.77,-0.45)]),plasma(specific)viscosity([MD=-0.19;95%CI(-0.22,-0.16)]),hematocrit([MD=-0.04;95%CI(-0.05,-0.03)])and other aspects were superior to the conventional treatment of Western medicine,the difference was statistically significant.Safety aspect:the reported adverse reactions were mild and tolerable events such as headache,dizziness,flush,etc.,no serious adverse events,and no separation from the report was found.Conclusion:on the basis of conventional western medicine,Xuesaitong injection can effectively improve the clinical efficacy,and has a high safety.However,due to the low quality of the included study and the small sample size,there is a potential bias in the study;therefore,the application and promotion of the research conclusions need to be cautious,and need to be further verified by more large sample,multicenter,double-blind clinical randomized controlled trials.
