Highly sensitive troponin I assay in the diagnosis of coronary artery disease in patients with suspected stable angina

BACKGROUND Evaluation of suspected stable angina patients with probable coronary artery disease(CAD)in the community is challenging.In the United Kingdom,patients with suspected stable angina are referred by community physicians to be assessed by specialists within the hospital system in rapid access chest pain clinics(RACPC).The role of a highly sensitive troponin I(uscTnI)assay in the diagnosis of suspected CAD in a RACPC in a“real-life”setting in a non-academic hospital has not been explored.AIM To examine the diagnostic value of uscTnI(detection limit 0.12 ng/L,upper reference range 8.15 ng/L,and detected uscTnI in 96.8%of the reference population),in the evaluation of stable CAD in a non-selected patient group,with several co-morbidities,who presented to the RACPC.METHODS One hundred and seventy two RACPC patients were assigned to either functional or anatomical testing according to the hospital protocol.RESULTS The investigations offered to patients were exercise tolerance test 7.6%,24 h ECG 1.2%,Echocardiogram 14.5%,stress echocardiogram 8.1%,coronary computed tomography angiography(CCTA)12.8%,coronary angiogram 13.4%,17.4%were diagnosed with non-cardiac chest pain,3.5%treated as stable angina,8.2%reviewed by cardiologists,electronic medical records were not available in 10.4%.Receiver operating characteristic curves for CAD used uscTnI values measured in patients who underwent functional testing,angiogram or CCTA.Values>0.52 ng/L showed 100%sensitivity and at>11.6 ng/L showed 100%specificity.In the range>0.52-11.6 ng/L,uscTnI may not have the same diagnostic potential.In patients assigned to coronary angiogram higher concentrations of uscTnI was associated with severe CAD.Low levels of uscTnI and low pre-test probability of CAD(QRISK3)may decrease patient numbers assigned to CCTA.CONCLUSION The uscTnI diagnostic cut-off values in a RACPC will depend on patient population and their presenting co-morbidity.In the presence of clinical comorbidities and previous CAD the uscTnI needs to be used in conjunction with clinical assessment.

Effects of adjuvant Chinese patent medicine therapy on major adverse cardiovascular events in patients with coronary heart disease angina pectoris:a population-based retrospective cohort study

Objective: This study aimed to explore the effects of Chinese patent medicine(CPM) in reducing the incidence of major adverse cardiovascular events(MACE) in patients with coronary heart disease(CHD) angina pectoris and improving clinical effectiveness and provide evidence for its use as clinical adjuvant therapy.Methods: Twenty-eight thousand five hundred and seventeen patients hospitalized with CHD angina pectoris from 6 hospitals were divided into CPM group(n = 11,374) and non-CPM group(n = 17,143) to evaluate the incidence of MACE, including myocardial infarction, percutaneous coronary intervention, and coronary artery bypass grafting.Results: The incidence of MACE in the CPM group was lower than that in the non-CPM group. CPM therapy was an independent protective factor that reduced the overall risk of MACE [adjusted hazard ratio = 0.40, 95% confidence interval(0.33;0.49)]. Patients in the CPM group who received one, two, or three types of CPM could benefit from adjuvant treatment with CPM, and taking more types of CPM was associated with a lower risk of MACE. In addition, the male population was better than the female population at taking CPM, and middle-aged people aged 55 to 64 were more suited to take CPM based on Western medicine.Conclusions: The use of CPM as adjuvant therapy can decrease the occurrence of MACE in patients with CHD angina pectoris,especially in men and middle-aged people, and the drug treatment plan should be optimized accordingly. However, this conclusion needs further verification by prospective cohort studies in the future.

Effect of action research-based exercise training guidance on exercise endurance and readmission rate in patients with stable angina pectoris due to coronary heart disease

Background Stable angina pectoris is a common subtype of coronary heart disease.Patients suffer from chest tightness,chest pain and crushing pain under the inducement of fatigue and emotional agitation.This study aims to investigate the effect of exercise training guidance based on action research on exercise endurance and readmission rate of patients with stable angina pectoris.Methods A retrospective study was conducted on 60 patients with stable angina pectoris due to coronary heart disease admitted to our hospital from February 2020 to November 2023.Patients were divided into a control group of 29 cases(receiving conventional exercise training guidance)and a guidance group of 31 cases(receiving action research-based exercise training guidance).Both groups received continuous training for one month.A comparison was made between the exercise endurance indicators[6-minute walk test distance(6MWT),peak oxygen consumption(peak VO2),anaerobic threshold(AT),exercise duration(ED)],quality of life,and readmission rate within 6 months after intervention in both groups.Results After 1 month of intervention,6MWT,peak VO2,AT and ED were increased in both groups,and those in the guidance group were higher than those in the conventional group(P<0.05).The score of quality of life(The 36-item shot-form health status survey,SF-36)in both groups was increased,and the guidance group scored higher than the conventional group(P<0.05).The readmission rate of patients in the guidance group was 6.45%,which was lower than that in the conventional group(27.59%)(P<0.05).Conclusions The application of action research-based exercise training guidance in patients with stable angina pectoris due to coronary heart disease has significant effects,improving exercise endurance,significantly improving quality of life,and reducing readmission rate,thus having practical value.[S Chin J Cardiol 2024;25(3):162-168]

Plasma levels of omentin-1 and visfatin in senile patients with coronary heart disease and heart failure

Objective:To investigate the alteration of plasma levels of omentin-1 and visfatin in elderly patients with coronary heart disease(CHD)and heart failure.Methods:Plasma omentin-1 and visfatin levels were measured in 90 subjects(29 stable angina pectoris(SAP)cases,30 unstable angina pectoris(UAP)cases and 31 age-and sex-matched healthy controls(age≥60 years)by enzyme-linked immunosorbent assay methods.According to the New York Heart Association classification.59 CHDs were divided into three groups:functional I class,11 cases;functional II/III class,36 cases;and functional IV class,12 cases.Results:The plasma level of omentin-1in CHO patients was significantly lower than thai of the control group.Otnenlin-lin SAP group and UAP group were significantly lower compared to the control group(there was no statistical significance between UAP group and SAP group;P>0.05).The plasma level of visfatin in CHD patients was significandy higher than that of the control group.Similarly,visfatin in SAP group and UAP group were all significantly higher compared to the control group,while there was no statistical significance between UAP group,and SAP group.The plasma omentin-1 level was negatively correlated with SBP(r=-0.264,P<0.05),positively correlated with HDL-c level(r=0.271,P<0.05);the plasma visfatin level was positively correlated with TC(r=0.292,P<0.05),negatively correlated with HDL-c level(r=-0.266,P<0.05).There was a negative correlation between plasma omentin-1 and visfatin levels(r=-0.280,P<0.05).Moreover,multiple linear stepwise regression analysis showed that omentin-1 and visfatin levels might be affected by HDL-c level.Logistic regression analysis showed that visfatin could be an independent risk factor of CHD.Conclusions:Decreased levels of omentin-1 and increased levels of visfatin may be involved in the occurrence and development of CHD.Omentin-1 and visfatin,independently,may be protective and pro-inflammatory cytokines.Additionally,both omentin-1 and visfatin may be related to lipid metabolism.Visfatin may be an independent risk factor of CHD.

Objective： To assess the efficacy of the Coronary Heart Disease （CHD） Capsules worked out by Prof. Deng -- in improving quality of life of CHD patients of qi deficiency with phlegm and blood stasis syndrome. Method： According to the WHO＇s diagnosis criteria of CHD, a total of 93 stable angina patients were divided into 3 groups using the single blinded method. The groups were evenly distributed into CHD Capsule treated group （CHDC）, isosorbide dinitrate control group （ID）, and Compound Prescription Danshen Droplet Pills control group （CPDDP）. Two courses of treatment lasting for 6 months were given. During the courses of treatment, the following parameters were observed： clinical symptoms of angina pectoris, ECG change, treadmill exercise test, 36 items in short form of health survey （SF-36） and Seattle Angina Questionnaire （SAQ） scale. Results： After 6 months of treatment, all the three groups showed good curative effect in angina pectoris, ECG and treadmill exercise test, differences between them had no statistical significance. The CHDC group showed a better result in nitro-glycerine stopping or alleviation rate and in improving symptoms than the other groups （P〈0.05）. The general health, vitality, role-emotional, mental health and reported health transition in the CHDC group were significantly better than those in the control groups （P〈 0.05）. The scores in physiological functioningrole, physiological function and pain alleviation were not different among the three groups. Conclusion. Prof. DENG Tie-tao＇s CHDC is effective in treating CHD with qi deficiency, phlegm and blood stasis and also in improving the quality of life. CHDC is more suitable to be used in long-term treatment than isosorbide dinitrate. The SF-36 and SAQ can be used to appraise the curative effect of traditional Chinese medicine agents for CHD angina pectoris.

Review of Medical Treatment of Stable Ischemic Heart Disease

Medical treatment is the initial treatment strategy and is the cornerstone of management in patients with stable ischemic heart disease (IHD). Many patients are not suitable for percutaneous or surgical revascularization because of unfavourable anatomy, or the presence of co-morbidities. In addition, many patients have recurrence of angina following revascularization due to restenosis or incomplete revascularization. Furthermore, randomized clinical trials comparing optimal medical treatment to revascularization have not clearly shown that myocardial revascularization is superior to optimal medical treatment. Traditional drugs for angina treatment include b-blockers, calcium channel blockers and nitrates. Newer drugs are available with different mechanisms of action and with equal efficacy that do not cause significant hemodynamic deterioration. The availability of these newer drugs expands the therapeutic potential of medical treatment to even a wider population with stable IHD. Revascularization in patients with stable ischemic heart disease has never been shown to reduce hard endpoints (death or myocardial infarction) in randomized clinical trials.

CLINICAL OBSERVATION AND STUDY OF MECHANISMSOF ACUPUNCTURE TREATMENT OFCORONARY HEART DISEASE

In the present paper, 80 in-patients with coronary heart disease were randomly assignedto acupuncture group, Western medicine group and acupuncture transient effect group, and 30 healthyblood donors were served as control group. At the same time of further observation on clinical therapeutic effects of acupuncture, effects of acupuncture on contents of blood monoamine, serotonin(5-HT), noradrenaline(NE) and dopamine(DA) for analyzing mechanisms of acupuncture treatment. Results indicated that 1. Therapeutic effects of acupuncture on angina pectoris and changes of ST-T segment of ischemic electrocardiogram (ECG) in patients of coronary heart disease were superior to thosein the Western medicine group, suggesting that acupuncture improves markedly left ventricular function; 2. The contents of blood 5-HT, 5-hydroxyindol acetic acid (5-HIAA ) and NE in patients ofcoronary heart disease were significantly higher than those in the healthy blood-donors; 3. After onetherapeutic course, the contents of blood 5-HT, 5-HIAA and NE in the acupuncture group were obviously lower than those before treatment and in the Western medicine respectively, indicating that themechanism of acupuncture treating coronary heart disease is related with regulatory effects of acupuncture on blood contents of 5-HT and NE.

Novel Imaging Approaches for the Diagnosis of Stable Ischemic Heart Disease in Women

Conventional recommendations for diagnostic testing for the evaluation of stable ischemic heart disease in women have largely paralleled those in men.Although they are designed primarily for the identifi cation of obstructive coronary artery disease(CAD),traditional approaches can lead to overtesting in women without differentiating who is truly at risk.Several unique factors related to the presentation,diagnosis,and underlying pathophysiology of stable ischemic heart disease in women necessitate a more specific approach to the assessment of their risk,complete with separate guidelines when appropriate.This overview highlights how advanced noninvasive imaging tools,including cardiac computed tomography angiography,positron emission tomography,and cardiac magnetic resonance imaging,are enabling very sensitive assessments of anatomic atherosclerotic plaque burden,macrovessel-and microvessel-related ischemia,and myocardial fi brosis,respectively.Moving forward,effective diagnostic testing will need to identify women at high risk of adverse cardiovascular events(not anatomically obstructive CAD per se)without overtesting those at low risk.Judicious application of novel imaging approaches will be critical to broadening the defi nitions of CAD and ischemia to better refl ect the whole spectrum of pathological phenotypes in women,including nonobstructive CAD and coronary microvascular dysfunction,and aid in the development of needed evidence-based strategies for their management.

Contemporary Management of Patients with Stable Ischemic Heart Disease

The overall goals of therapy for patients with stable ischemic heart disease are to minimize the likelihood of death while maximizing health and function.Initial risk assessment with noninvasive testing is indicated to determine whether invasive evaluation is needed in addition to medical therapy.All patients with stable ischemic heart disease need optimal medical therapy,which includes risk factor management with lifestyle modifi cations and pharmacologic therapy.First-line pharmacologic therapy is focused on preventing myocardial infarction and death with antiplatelet agents,lipid-lowering therapy,and antihypertensive therapies.In addition,antianginal therapy and anti-ischemic therapy are indicated to alleviate symptoms,reduce ischemia,and improve quality of life.The commonly used antianginal agents include nitrates,beta-blockers,calcium channel blockers,and ranolazine.When medical therapy is not adequate to relieve angina,revascularization with percutaneous coronary intervention or coronary artery bypass grafting is indicated.We review the indications and evidence for antianginal agents and other therapies for angina.

Application progress of cognitive behavioral therapy in coronary heart disease

To As one of the most common cardiovascular diseases,coronary heart disease has a high morbidity and mortality.In recent years,non-drug therapy has been put on equal importance with drug therapy due to its simple operation and fast onset.Cognitive behavioral therapy,as a kind of non-drug therapy,has been widely used to improve the physical and mental symptoms of patients with coronary heart disease.This article reviews the origin,concept,theoretical basis,characteristics,technology,and current research status of cognitive behavioral therapy in patients with coronary heart disease,in order to provide a reference for the clinical development of cognitive behavioral therapy.
