Filter by:Coronary heart disease (CHD) is one of the leading causes of mortality and morbidity. PCI, as a well-proved and booming measure in CHD management, is invasive and of high cost, however the knowledge about the real-life PCI use in China is limited. Within a nation-wide and regional representative probability sample of hospitals in China, 14,000 CAG/PCI inpatient cases will be sampled randomly from 2001 to 2011. The sampled medical records will be reviewed and abstracted in the national coordinating centre, in order to evaluate the treatment pattern, outcomes, and cost for PCI, during the past decade. Basic data and innovative evidence will accelerate evidence-based clinical practice and policy making, and improve patients outcomes in future finally.
Coronary heart disease (CHD) and heart attacks pose a serious health risk to men and women, however the knowledge about the real-life AMI management in China is limited. Within a nation-wide and regional representative probability sample of hospitals in China, 27,800 AMI inpatient cases will be sampled randomly from 2001 to 2011. The sampled medical records will be reviewed and abstracted in the national coordinating centre, in order to evaluate the treatment pattern, outcomes, and cost for AMI patients, during the past decade. Basic data and innovative evidence will accelerate evidence-based clinical practice and policy making, and improve AMI patients outcomes finally.
Depression is frequently observed in patients with coronary heart disease (CHD) and represents a significant risk factor for major cardiovascular events. Previous study has proved that high sensitive C-reactive protein (hsCRP) was an independent predictor for depression in CABG patients at 6 months after bypass surgery. Statins can effectively reduce the blood levels of hsCRP. This study aim to examine whether statins can improve the prognosis of depressive patients undergoing coronary artery bypass surgery through reducing the levels of hsCRP.
The purpose of the study is to target inflammation to reduce progression of noncalcified plaque in the coronary arteries using omega-3 fatty acid supplementation compared to standard of care.
This study is a single centre pilot for a randomized trial comparing all-blood cardioplegia to more dilute 4:1 blood cardioplegia during cardiac surgery. The hypothesis is that all-blood cardioplegia will be associated with less blood transfusion and better cardiac function.
The purpose of this study is to demonstrate that a BioFreedom™ Drug Coated Stent is non-inferior to a bare metal stent at one year as measured by the composite safety endpoint of cardiovascular death, myocardial infarction and definite/probable stent thrombosis, and that its efficacy is superior to a bare metal stent as measured by clinically driven TLR at one year.
During coronary bypass surgery, veins are taken from the leg and applied to the heart and aorta to 'bypass' narrowings in the coronary arteries. However using an artery in the chest, the internal mammary artery, means that the bypass lasts longer than using veins. The investigators recently showed that using an artery from the arm as a bypass vessel, the radial artery, also had less furring up than veins 5 years after surgery. Now the investigators would like to ask patients to come back for an angiogram 10 years following surgery.
This study will evaluate the influence of total atherosclerotic burden assessed by 3-vessel fractional flow reserve (FFR) on the clinical outcomes of the patients with multi-vessel disease. For this purpose, the clinical data of the patients with 3-vessel intermediate coronary artery disease, whose FFR was measured at all 3-vessels due to their own clinical needs, will be analyzed.
The substitution of polyunsaturated fatty acids (PUFA) for saturated fatty acids (SFA) is a cornerstone of worldwide dietary advice for coronary heart disease (CHD) risk reduction. However, clinical CHD benefits specific to the omega-6 PUFA linoleic acid (LA), and distinct from omega-3 PUFAs, have not been established. The Sydney Diet-Heart Study (SDHS; 1966-1973) was a randomized controlled secondary CHD prevention trial testing whether selectively increasing omega-6 LA from safflower oil in place of SFA reduced CHD and improved survival. A full analysis of mortality outcomes has not been published. The investigators recovered the original SDHS dataset, which included detailed longitudinal dietary, smoking and coded mortality data, permitting evaluation of smoking relapse rates, and all-cause, CVD and CHD mortality outcomes by nutrient intake and duration of diet exposure. Data recovery also permitted the first complete meta-analysis of LA intervention trials on mortality outcomes. Objectives are (1) to evaluate whether increasing dietary linoleic acid alters CVD and CHD mortality, and (2) to assess whether changes in smoking relapse rates contribute to observed mortality differences.
Left main stenosis use to be treated by bypass but with the improvement of angioplasty techniques, an increasing number of patients are submit to left main coronary angioplasty. Consequences of left main intra stent stenosis can be disastrous yet, for the moment, no precise recommendation concerning the follow up of these patients exist. The investigators ought to determine if stress echocardiography can predict left main intra stent stenosis as well (non inferiorly)as control angiography that use to be done.
