Filter by:To investigate the mid- and long-term effect of Enhanced External Counterpulsation combined with guideline-driven standard treatment on patients documented with and/or at high risk of coronary artery disease.
The trial will investigate the accuracy of Dual Source CT coronary angiography to detect coronary artery stenoses in patients with chest pain who have, based on clinical criteria, an intermediate likelihood for the presence of coronary artery stenoses. No beta blockers will be used to lower the heart rate for the examination. The hypothesis is that Dual Source CT will allow the detection of vessels with at least one coronary artery stenosis with a sensitivity of more than 90%.
Coronary artery disease (CAD), the most common type of heart disease, is caused by hardening of the arteries, or atherosclerosis that is an inflammatory process in which immune mechanisms interact with metabolic risk factors to initiate, propagate, and activate lesions in the arterial trees. Epidemiological studies have found that increased cardiovascular risks are associated with increased levels of inflammatory cytokines (eg, interleukin-6 [IL-6] and tumor necrosis factor-alpha[TNF-alpha]) or their hepatic product, C-reactive protein (CRP). Higher expression of interleukin-Ibeta(IL-1beta),IL-6, monocyte chemotactic protein-1 (MCP-1), and TNF-alpha were observed in epicardial adipose tissues in patients with CAD. These findings suggested that the pericoronary tissues could be a source of inflammatory mediators or act as paracrine that lead to vascular inflammation on CAD pathogenesis. However, adiponectin, a kind of adipocytokine, produced and secreted exclusively by adipose tissue, has been reported to have a variety of anti-inflammatory functions against atherosclerosis, resulting in risk reduction for incidence of CAD events. It remains unclear whether adiponectin and inflammatory mediators in mediastinal adipose tissue contribute to CAD. We therefore aim to analyze the expression of adiponectin and inflammatory mediators in mediastinal adipose tissue between patients with CAD and with valve diseases, and to correlate these parameters with clinical atherosclerotic risks, medications (statins or antiplatelet), and blood sugar.
The Stenting of Renal Artery Stenosis in Coronary Artery Disease (RASCAD) study is a randomized controlled trial designed to evaluate the effect of renal artery stenting+medical therapy versus medical therapy alone on left ventricular mass progression and cardiovascular morbidity and mortality in patients affected by coronary artery disease and renal artery stenosis.
The multicenter study evaluates the diagnostic performance of coronary Computed Tomography Angiogram (CTA) with multi-slice computed tomography (MSCT) in comparison with X-ray coronary angiography and the factors affecting the accuracy of coronary CTA in diagnosing stenosis of coronary arteries. Furthermore, the study tends to establish the standard of image quality and associated factors that may ensure accurate diagnosis of coronary stenosis with coronary CTA.
This is a prospective, multi-center registry to evaluate safety and effectiveness of the Everolimus Drug Eluting Stent for treatment coronary revascularization in Chinese patients with long lesion, small vessel or multi-vessel diseases.
The purpose of this study is to determine whether direct endomyocardial injection of autologous bone marrow cells is effective for enhancement of neovascularisation in patients with ischaemic heart failure.

Shortness of breath, fatigue, and exercise intolerance are clinical symptoms of chronic heart failure (CHF). Recent studies suggested that peripheral impairment was the major cause of clinical symptoms, and mechanism may be related to neuroendocrine impairment and vascular smooth muscle dysfunction. It results in increased peripheral resistance that may influence limb blood flow, muscle fitness and activities of daily.The purposes of this study are 1. to compare muscular strength, endurance, and perfusion of quadriceps between CHF patients and healthy controls by isokinetic test and near-infrared spectroscopy (NIRS) and difference in activities of daily living 2. to compare endothelium function between CHF patients and healthy control subjects 3. the relationship between endothelium function, muscular strength, endurance, perfusion, and metabolism of quadriceps.
Mechanisms that link metabolic syndrome to atherosclerosis are incompletely understood. As a part of Hämeenlinna Metabolic Syndrome Research Program (HMS) surrogate indicators for atherosclerosis are studied in 120 men with metabolic syndrome, 120 men with coronary heart disease and 80 physically active controls and in different settings.
