The aim of study is to investigate the impact of two different training modalities (high intensity interval training (HIIT) versus moderate intensity continuous exercise training (MICET) on cognitive performance, cerebral oxygenation, cardiac output and physical fitness in older healthy adults, patients with metabolic syndrome, coronary heart disease and heart failure. The investigators hypothesized that HIIT modality will lead to a larger improvement in physical fitness (i.e. VO2peak), cardiovascular parameters (cardiac output and stroke volume) and cognitive performance at rest and during submaximal exercise. The primary endpoint will be the improvement in cognitive performance.
Strategies for myocardial protection during open heart surgeries are desired. Several experimental studies have shown beneficial effects of remote ischemic preconditioning (RIPC). The underlying mechanisms are not totally understood. This study intends to evaluate molecular mechanisms involved with RIPC on myocardium of patients underwent open heart surgeries.
The purpose of this study is to evaluate the efficacy and safety of paclitaxel-eluting balloon (SeQuent® Please) for treatment of lesions in native small coronary arteries.
This study will compare how well a new radiolabeled imaging agent ECDG compares to the current testing for coronary artery disease (radiolabeled Sestamibi) during a rest and stress cardiac test as documented from results of a coronary angiogram (if performed).
Ticagrelor is a reversible direct acting P2Y12 antagonist, which has shown to be superior to clopidogrel, in adjunct to aspirin, in preventing recurrent ischemic events. Ticagrelor is considered a first line therapy to be administered as soon as possible in ACS patients. However, the pharmacodynamic effects of ticagrelor at the recommended 180mg loading dose are delayed in patients with STEMI undergoing primary PCI. The use of higher loading dose regimens of ticagrelor has therefore been advocated. The proposed investigation will have a prospective, randomized, parallel design in which STEMI patients undergoing primary PCI will be randomized to receive three different loading dose of ticagrelor (180 mg, 270 mg and 360 mg). Pharmacodynamic testing will be performed at several time points to test our study hypothesis that a higher loading dose regiment will achieve more promptly enhanced platelet inhibitory effects.
Title: A randomized, double-blind, multi-centered, placebo-controlled trial to examine effects of of Heart-protecting Musk Pill on clinical outcomes in patients with chronic stable coronary artery disease Objective: To examine effects of of Heart-protecting Musk Pill, a traditional Chinese medicine, on clinical outcomes in patients with chronic stable coronary artery disease The study hypothesis: The null hypothesis: the combined incidence of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke in the treatment group is the same as that in control group. The alternative hypothesis: the combined incidence of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke in the treatment group is different from that in control group. Sample size: 2700 patients will be randomized, 1350 in treatment group and 1350 in placebo group. Number of sites: 99 sites in China Study drugs: Heart-protecting Musk Pill and the matching placebo pills. Design: A randomized, double-blind, multi-centered, placebo-controlled trial. Patients will be randomized to treatment group and placebo group after screening and get corresponding treatment as follow. Treatment group: Standard treatment for coronary artery disease plus 2 Heart-protecting Musk Pills each time, three times a day by mouth for 24 months. Control group: Standard treatment for coronary artery disease plus 2 placebo pills each time, three times a day by mouth for 24 months. Patients will be followed up at baseline, 1, 3, 6, 9, 12, 18, 24 months after randomization. During follow-up period, patients could undertake PCI or CABG if angina get out of control or evidence of ischemia aggravated is found.
The purpose of this study is to investigate the prevalence of abdominal aortic aneurysms (AAA) among male patients with coronary artery disease (CAD) verified in coronary angiography. Ethiology of AAA is known to be common with atherosclerotic arterial diseases (coronary artery disease, peripheral artery disease and carotid artery disease), so the hypothesis is that AAA should be more common among these CAD patients, thus making screening of these patients (for AAA) more cost-efficient. Study will be carried out as a multi-center prospective screening study. Data will be collected in North Karelia Central Hospital, Kuopio University Hospital and Tampere University Hospital. Data consists of 200 consecutive coronary angiography patients in each hospital, resulting in 600 patients in total. All male patients with diagnosed CAD will be recruited for the study and screened for AAA with ultrasound. Nevertheless, patients with previously known AAA will be excluded from the study.
The purpose of this study was to compare FBP-, hybrid IR-, and IMR techniques to assess their role in the identification of coronary artery disease and abnormalities in cardiac structures.
Previous reports have shown a possible drug interaction between clopidogrel and proton pump inhibitors (PPI´s), which could result in increased number of adverse cardiovascular events among patients on dual antiplatelet therapy(DAPT). Because of this, ranitidin has been proposed as an alternative drug to PPI´s for prophylaxis of gastrointestinal bleeding in patients who need DAPT. The study´s aim is to test the hypothesis that ranitidin doesn´t have any influence on clopidogrel pharmacodynamic.
