Filter by:Selection of a treatment strategy for patients with symptoms due to coronary artery disease requires consideration of patient preferences. In current clinical practice, patient preferences for treatment may not be known prior to diagnostic coronary angiography. The investigators will test an internet-based shared decision-making tool which will provide education and solicit preference information prior to angiography. The investigators seek to determine if this tool can accurately assess patient preferences, and if these preferences will lead to a change in clinical management.
This is a prospective, double-blind, placebo-controlled, randomized, single-center (North Florida- South Georgia VA Medical Center) study. The study objective is to determine if ranolazine improves angina symptoms at 4 months compared with placebo among stable coronary artery disease patients who have demonstrable myocardial ischemia, but who do not undergo revascularization
1. The primary purpose of this study is to determine the diagnostic accuracy of the CADscore System, a new danish technology that records sounds from turbulence of bloodflow in the coronary vessels. And secondary: 1. To determine the accuracy of cardiac magnetic resonance imaging (MRI) and single-photon emission computed tomography (SPECT), as secondary tests after detection of obstructive anatomic coronary artery stenosis by coronary computed tomographic angiography (CCTA). 2. To examine the patient population for bio-genetic markers related to development of arteriosclerosis. 3. To evaluate virtual fractional flow reserve (vFFR) computed from coronary angiograms.
Slow coronary flow is an angiographically diagnosed phenomenon defined as delayed opacification of epicardial arteries in the absence of significant arterial narrowing and blockade. Endothelial dysfunction at the level of microarteries have been proposed as the main pathological mechanism in this regard. Available evidence suggest that standard anti-angina medications (e.g. nitroglycerin) that solely target large coronary trunks might not provide adequate symptomatic relief in patients with slow coronary flow phenomenon. It is hypothesized that anti-angina medications which exert vasodilatory effects in large coronary arteries as well as small dividing branches might be superior to nitroglycerin in amelioration of angina symptoms. The present randomized clinical trial was thus designed and conducted to compare the short-term efficacy of nicorandil (a dual-acting anti-angina medication with effects on both large and small coronary vessels) with nitroglycerin in a group of patients with slow coronary flow presented with frequent angina episodes.
The purpose of this study is to compare early vessel healing after implantation of SYNERGY drug eluting stent (DES) or BioMatrix NeoFlex DES at one and three months in two cohorts.
The purpose of this study is to determine the effects of ranolazine on different markers of cardiometabolic disease in women with stable angina.
Despite the well-known health benefits of physical exercise in the prevention of chronic diseases, less attention has been focused on the use of physical exercise as an essential part of good treatment for chronic disease. The aims of the study are to investigate the feasibility, medical effects, cost-effectiveness, and social perspectives of the individualized exercise-based rehabilitation [2 different high-intensity training (HIT) protocols combined with usual care (UC)] after acute coronary artery disease (CAD) event. The medical aim is to study mediating mechanisms of the physiological, biochemical and molecular effects of exercise training on the clinical outcomes. The aim of the health-economic evaluation is to assess the changes in the Health-Related Quality of Life (HRQL) and health care related costs for estimating the cost-effectiveness of HIT-based exercise rehabilitation. The purpose of the sociological analysis is to find out the social processes which make possible the emergence of the desired welfare effects.
The aim of this study was to explore whether lacidipine at doses of 2 mg, 4 mg and 6 mg decreased the symptoms of angina, compared to placebo in patients with chronic stable angina
The purpose of this study is to understand the use of Corus CAD also known as Age/Sex/Gene Expression score (ASGES) in the clinical decision making process of patients who underwent the evaluation of chest pain or anginal equivalent symptoms. Specifically, to better understand whether the use of the assay in clinical decision making resulted in changes in noninvasive diagnostic test ordering or diagnostic yield of additional tests ordered and/or invasive angiography.
The purpose of this study is to compare the extent of coronary vessel stenosis between coronary spasm-induced angina attacks (named vasospastic angina, VSA) patients and health volunteers by multi-detector computed tomography angiography (MDCTA), and to evaluate the diagnostic efficacy of MDCTA in patients with VSA.
