Filter by:We hypothesize that Coronary Artery Disease (CAD) severity assessed by SYNTAX score is an independent predictor of recurrent or persistent angina following coronary revascularization. The SYNTAX score is a score that suggests the severity of coronary artery disease detected by coronary angiography. Coronary revascularization is a procedure that occurs in two ways, a percutaneous coronary intervention (PCI) and a coronary artery bypass graft (CABG) and is done when there is narrowing and blockage or hardening of the arteries (atherosclerosis) surrounding the heart. Narrowing and blockages reduce blood flow to parts of the heart causing chest pain (known as angina) and sometimes myocardial infarction.
Women have less significant blockages of coronary arteries, however have greater symptoms and worse outcomes compared to their age-matched male counterparts. This paradox has led to the recognition and importance of the microvasculature ( small vessels) as a contributor to symptoms and outcomes. Nebivolol has unique antioxidant properties and dilates blood vessels and it is therefore proposed that treatment with nebivolol will reduce angina (chest symptoms) in women with microvascular disease as well as improve exercise capacity, reduce resource utilization and improve other measures of artery function.
The purpose of the study is to evaluate the efficacy of therapy with autological CD133+ cells in patients with angina resistant to pharmacological treatment and without the possibility of effective revascularization. Cells will be isolated from patients bone marrow and administered directly into the muscle of left ventricle. The main objective is to assess the treatments' influence on improvement of myocardial perfusion and function, and on decrease of occurrence of symptomatic angina.
This phase III study is designed as a double blind, randomized, multi-nation, multi-center, placebo controlled clinical research, which aims to evaluate the safety and efficacy of Dantonic® (T89) in patients with chronic stable angina pectoris.
The purpose of the study is to determine whether scoring balloon (SCB) plus paclitaxel-coated balloon (PCB) is superior to PCB alone for the treatment of restenosis within "limus"-eluting stents (LES)
It is recognized that endothelial dysfunction is a major factor contributing to the atherogenic process. Abnormal function of the endothelium is detectable prior to obvious intimal lesions in patients with risk factors for atherosclerosis. Endothelial dysfunction is a systemic disorder and a key variable in the pathogenesis of atherosclerosis and its complications. Measurement of peripheral vasodilator response with fingertip peripheral arterial tonometry (PAT) technology (EndoPAT; Itamar Medical, Caesarea, Israel) is emerging as a useful method for assessing vascular function. EndoPAT may be a potential valid test increasing the accuracy, sensitivity and specificity for detection of subjects to chest pain unit (CPU) with chest pain but no obvious coronary artery disease (CAD). This is a relatively fast non-invasive bedside test, relatively low-cost and has no side effects. Therefore, the primary objective of the study is to test the hypothesis that abnormal endothelial function as assessed by EndoPAT testing will increase the prediction of the short (in-hospital) and long-term (1-year) outcome of patients presenting to the chest pain unit.
This study was advocated by Institute of Basic Research in Clinical Medicine, China Academy of Chinese Medical Sciences in October 2011. It was funded by China major scientific and technological specialized project for 'significant new formulation of new drugs'. Kudiezi is kind of Chinese Medicine injection used for treating coronary heart disease and angina pectoris in many Chinese hospitals. The purpose of this study is to determine adverse drug events or adverse drug reaction in large sample size 30,000 patients.
There is a sharp rise in the rate of coronary heart disease diagnoses and chest pain consultations in the 90 days before a first heart attack. There is some evidence that chest pain and angina symptoms in this period have a beneficial effect on heart attack outcomes in hospital and shortly after discharge. However, the available evidence is lacking in three key areas. First it is based on a retrospective patient report of symptoms after the heart attack has occurred; this means that patients are required to survive their heart attack and may make errors when reporting prior symptoms. Second, evidence for an effect on longer term outcomes, and coronary outcomes in particular (e.g. coronary death, further heart attacks) are unknown. Third, there is conflicting evidence that these effects might differ by age, in men and women, and according to treatment in hospital. The investigators hope to address the limitations in the evidence by performing a large, prospective study of the occurrence, timing and effect of different types of symptoms and disease diagnoses occurring before heart attack. The investigators hypothesise that prospectively collected, clinical measures of chest pain symptoms and cardiovascular diagnoses in primary care will have a beneficial effect on short term coronary mortality and may have a beneficial effect on longer term coronary outcomes.
This is a prospective, multi-center study examining the clinical impact of the Corus CAD (Age/Sex/Gene Expression score - ASGES) assay in approximately 250 evaluable subjects with no history of obstructive coronary artery disease who now present with chest pain or anginal-equivalent symptoms to a primary care physician (PCP) for evaluation.
- Although aging process appears to be generally characterized, investigators have been paid much attention to the specific target molecules, which leads to discover the clinical markers of the senescence. The present study is to investigate the clinical and biological profile of cognitive decline and functional cardiac senescence in healthy middle aged and elderly Korean volunteers. - This study was conducted as a cross-sectional, single-center, comparative clinical study. - Each volunteer was given informed consent for checking cognition and cardiac function. Blood and urine samples were collected to analyze genome, proteome, and metabolome to assess cognition and cardiac function of its muscle enzymes.
