Filter by:Participants had randomly divided into two equal groups. Group (A) had received a program of high intensity interval training 30-40 minutes three times per week for one month. The participant will start cycling slowly for five minute without resistance at the beginning of the exercise as warming up, then the active phase will last 20-30 minutes, then decrease the speed with no resistance at the end of the exercise as cooling down. Group (B) will receive a program of inspiratory muscle training by using the threshold based inspiratory muscle trainer for 10-15 minute daily with frequency three times per week for four weeks.
The aim is to examine the expression of αvβ3 integrin using a novel selective radiotracer in patients with chronich ischemic heart disease and investigate if it is a suitable tool for predicting myocardial recovery and thus prognosis after intervention.
The primary objective of this study was to investigate whether there is a clinically meaningful effect on QTc change from baseline relative to placebo after administration of 10 mg at steady state in patients with stable CAD (coronary artery disease).
This study proposes to develop an MRI technique named Coronary Atherosclerosis T1-weighed Characterization (CATCH) that will improve the quality and reliability of coronary atherosclerosis evaluation, as well as simplify the scanning process and significantly shorten imaging time compared with conventional imaging methods.
This is a prospective study which aims to explore the effect of Trimetazidine on the improvement of coronary microvascular dysfunction in patients with INOCA (ischemia and no obstructive coronary artery disease). Enrolled patients will be assessed SAQ(Seattle Angina Score), Canadian Angina Grade(Canadian Cardiovascular Society, CCS), Six-Minute Walk Test, CFR(coronary flow reserve) .CFR inspection with D-SPECT and pressure guide wire.Patients will receive six months Trimetazidine(35mg tid) after enrollment. And their SAQ (Seattle Angina Score), Canadian Angina Grade(Canadian Cardiovascular Society, CCS), Six-Minute Walk Test, CFR will be followed up.
The primary objective in this study is to investigate if vein grafts harvested and implanted with the non-touch technique are superior to conventional vein graft technique with respect to mid-term patency, in patients undergoing CABG surgery.
This prospective randomized study elucidates the effects of exogenous nitric oxide delivered to the extracorporeal circulation circuit for cardioprotection against ischemia-reperfusion injury during coronary artery bypass graft surgery with cardiopulmonary bypass.
Recommendations for cardiovascular rehabilitation (CVR) encourage exercise training, primarily involving the aerobic system, to allow patients to regain independence in daily activities. However, the lactic anaerobic process is also involved during these activities (stair climbing, carrying loads, etc.). Hence there is a major interest in accurately assessing patients' anaerobic capacities in order to tailor suitable exercise programs. However, there are no functional tests specifically dedicated to the evaluation of lactic anaerobic metabolism and adapted to people with coronary disease. The investigators offer a dedicated test, the short and fast test (SFST), which can be applied in current clinical practice and has already been evaluated in a population of healthy subjects. The purpose of this project is to evaluate the safety, feasibility and validity of SFST in a population of patients with coronary artery disease.
Polymorphisms of the cytochrome P450 (CYP) 2C19 enzyme has been consistently shown to modulate clopidogrel response. Accordingly, the Food and Drug Administration (FDA) has issued a warning on the potential for reduced efficacy of clopidogrel among carriers of loss-of-function alleles (LOF) for CYP2C19 and suggest considering alternative antiplatelet therapies for these individuals. The pharmacodynamic (PD) effects of prasugrel and ticagrelor are not affected by CYP2C19 genetic polymorphisms. However, to date there are no head-to-head PD comparisons between these agents among patients with different CYP2C19 genetic polymorphisms, which is currently under investigation in CAD patients undergoing PCI at UF Health-Jacksonville (UFJ 2014-12, NCT 02065479). In order to rule out play of chance findings, pharmacogenetic investigations require external validation cohorts to support the study findings. Therefore, the present randomized study is designed to serve as an external validation cohort conducted in patients with established CAD not undergoing PCI testing the non-inferiority in platelet reactivity of prasugrel versus ticagrelor among CYP2C19 LOF allele carriers.
In systemic lupus erythematosus (SLE), cardiac manifestations, e.g. coronary artery disease (CAD) and myocarditis are leading causes of morbidity and mortality. The prevalence of subclinical heart disease in SLE is unknown. We studied whether a comprehensive cardiovascular magnetic resonance (CMR) protocol may be useful for early diagnosis of heart disease in SLE patients without known CAD
