Filter by:OBJECTIVES: The primary objective of this study is to assess the safety and efficacy of the Supralimus - Core™ Sirolimus Eluting Stent in de novo native vessel obstructive coronary artery disease. STUDY DESIGN: This is a single centre, prospective study. Approximately 105 patients were enrolled in the study. Patients were followed for twelve months post-procedure. All patients were to have a repeat angiography at 8 months. STUDY POPULATION: The study population consisted of approximately 105 patients with de novo native vessel obstructive coronary artery disease with no specific criteria. Patients from the daily practice were included. Patients had to meet all eligibility criteria for inclusion into the study. ENDPOINTS: The primary safety endpoint of the study is defined as Major Adverse Cardiac Events (MACE) at 30 days. The primary efficacy endpoint is the in-stent binary restenosis rate at 8-month follow-up determined by off-line Quantitative Coronary Angiography. The following secondary efficacy endpoints were assessed - Angiographic success - Procedure success - Quantitative Coronary Angiography derived vessel parameters in-stent and 5 mm proximal and 5 mm distal from the edge of the stent: acute gain, MLD, % DS, late loss, mean diameter. In-stent pre-, post and at 8-month follow-up. - Clinically justified Target Lesion Revascularization (TLR) at 12 months The following secondary safety endpoints were assessed: - MACE until 12 months - Device related SAEs until 12 months - Angiographic stent thrombosis: Subacute (after procedure until 30 days) and Late (after 30 days until 12 months)
Coronary artery disease has a high death toll in the Western world. Changes in lifestyle, particularly in nutrition and physical activity may significantly reduce a severe coronary atherosclerosis within one year without the use of medication. Several dietary studies have shown that not only the progress of coronary artery disease can be slowed down, but it may also increase significantly the survival of these patients. Up until now there is little known about therapeutic effects by complementary medicine. In particular, Traditional Tibetan medicine dietary programs have shown in few case reports that weight could be reduced in patients with obesity. Therefore, the investigators developed a specific dietary program for patients with coronary artery disease, who have an increased cardiovascular risk profile according to the criteria by the International Diabetes Federation (IDF).
Coronary artery disease (CAD, cholesterol plaque buildup in the heart arteries) is the most common cause of left ventricular systolic dysfunction (weakening of the heart muscle). The standard test to find coronary artery disease is coronary angiography. This test is highly accurate but is invasive and carries a small risk of complications. This study investigates ultrasound of the carotid (neck) arteries as a screening test for severe coronary artery disease as a cause of left ventricular systolic dysfunction. It is hypothesized that carotid ultrasound will have excellent negative predictive value for severe CAD.
The purpose of this study is to determine whether rivaroxaban in addition to standard care reduces the risk of the composite of cardiovascular death, myocardial infarction, or stroke in patients with a recent acute coronary syndrome compared with placebo.
Air pollution is a major cause of cardiorespiratory morbidity and mortality. The exact components of air pollution that underlie the cardiovascular effects are not yet known, but combustion-derived particulate matter is suspected to be the major cause. Epidemiological studies have shown that exposure to air pollution causes exacerbation of existing cardiorespiratory conditions leading to increased hospital admissions and death. The investigators have recently conducted a series of controlled exposure studies to urban particulate matter and diesel exhaust in healthy volunteers and patients with coronary heart disease. The investigators found that controlled exposure to dilute diesel exhaust in patients with prior myocardial infarction induced asymptomatic myocardial ischaemia with an increase in electrocardiographic measures of myocardial ischaemia. Whilst important, further questions remain: (i) does air pollution exposure exacerbate ischaemia and reduce exercise tolerance in patients with symptomatic angina pectoris, (ii) do "real world" exposures as encountered in the urban environment of major cities have similar effects, and (iii) can a simple face mask intervention to reduce exposure to particulate air pollution improve health outcomes in patients with coronary heart disease?
The relation between obesity and ischemic heart disease (IHD) is under considerable debate. The reduction in all-cause mortality and, more specifically, the reduction in cardiac-related mortality seen after weight-loss surgery, may be due to regression or slowing developement of subclinical IHD. Function of cells lining the arteries (endothelium) is closely related to the state of IHD and its measurement can serve as a surrogate marker for the existence and severity of IHD. The investigators hypothesize that the prevalence of undiagnosed IHD in the morbidly obese population is high and that following surgery for weight reduction there is a halt in the progression, or even a regression in its severity. The study includes measurement of endothelial function before and after weight-reducing surgery.
Lexiscan(TM) has ideal properties for Rb-82 PET imaging and the stress response it invokes may offer multiple advantages for the diagnosis of coronary disease and functional abnormalities. The goal of this investigation is to establish quantitative equivalence of Lexiscan(TM) rest/stress Rb-82 PET images to dipyridamole rest/stress images.
People with coronary artery disease (CAD) or people who have had a heart attack may develop a leak in the mitral valve of their heart and may therefore need to undergo surgery to fix the valve. The best way to fix the mitral valve remains undetermined. This study will evaluate whether it is better for people with severe mitral valve leakage to undergo a mitral valve replacement procedure or a mitral valve repair procedure.
Coronary artery bypass grafting (CABG) is a procedure that people with coronary artery disease (CAD) may undergo to increase blood flow to the heart. During a CABG procedure, people who have a leak in one of the valves in the heart—the mitral valve—may at the same time undergo a procedure that repairs the valve. This study will evaluate whether people with moderate mitral valve leakage would be better off undergoing CABG plus the mitral valve repair procedure or undergoing CABG alone.
It's reported that USCOM can be used to measured patients' CO and CI conveniently, accurately and not confined to place, because of it's no aggressive, it's accuracy is doubtful.
