Filter by: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.
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 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.
The purpose of this study is to demonstrate that the strength of agreement between single photon emission computed tomography (SPECT) imaging with regadenoson following inadequate exercise stress testing and SPECT imaging with regadenoson alone is not inferior to the strength of agreement between two sequential regadenoson SPECT images without exercise.
The main aim of this study will evaluate differences in serum levels of tryptase in study population. Will be selected a number of 350 patients hospitalized for coronary heart disease.
Physical rehabilitation is a key element in the treatment of patients with cardiovascular diseases, and recent evidence has shown that supervised exercise programmes can prevent cardiovascular events, improve physical function and quality of life. Individualized exercise prescription based on appropriate frequency, intensity and duration is recommended. Furthermore, recent studies have shown that physical cardiac exercise training can influence inflammation of the vessel wall and hence reduce development of arteriosclerosis in coronary vessels. In the literature are divergent conclusions on appropriate frequency and duration of physical rehabilitation programs in order to improve physical function and reduce arteriosclerosis. The purpose of this study is to investigate the efficacy of an optimized physical rehabilitation programme compared to a conventional programme on physical fitness, health related quality of life and vascular inflammation.
The aim of the study is to evaluate platelet function variations according to the delay since last aspirin intake (12 vs 24 hours)in a population of diabetic patients with previous Coronary Artery Disease.
During cardiac displacement for off-pump coronary artery bypass(OPCAB) surgery, the presence of air underneath the displaced heart compromises the transgastric (TG) window for transoesophageal echocardiography(TOE). The investigators hypothesised that placing a saline-filled glove would enhance TG transmission of ultrasound and facilitate TOE imaging for monitoring left-ventricular regional wall motion (LV-RWM). For left circumflex coronary artery (LCX) grafting in OPCAB surgery (n=13), mid-oesophageal (ME) and TG TOE images are recorded before cardiac displacement (T control), after displacing and stabilising the heart (T-displaced), and after placing a saline bag (saline-filled surgical glove) underneath the displaced heart (T-saline bag). Following data are determined by integrated TG and ME TOE views (ME+TG) at T-control, T-displaced and T-saline bag: number of readable segments (NRS) in a 17-segment model; NRSs in basal and mid-TG short axis views; NRS in 5-LV segments of the LCX territory; the incidence of inadequate monitoring of LV-RWM (NRS < 14/16 except for the apex in 17-segment model).
The purpose of this study is to demonstrate the safety and efficacy of the investigational BIOTRONIK PRO-Kinetic Energy stent in subjects with atherosclerotic disease of native coronary arteries.
