Filter by:After surgery, patients who have cardiogram changes consistent with a lack of oxygen to the heart muscles, also known as myocardial ischemia, have been found to have 9 times the chance of having an event such as a heart attack during the subsequent 30 days. It is not known if monitoring and treating ischemia will prevent events such as heart attacks. It is not known if such monitoring and treatment can be done on the regular surgical wards. In this pilot study, we hope to demonstrate that such a study is feasible, and the maintenance of blinding is possible. The primary outcomes are to show that such monitoring after surgery is possible in ≥ 95% of patients, to show that response and treatment to such ischemia in ≤ 1 hour is possible in ≥ 90% of patients, and that blinding between the standard and active treatment groups is possible for 50% ± 1 s.d.. With the pilot study data, if successful, we will be applying for peer-reviewed funding for a full study.
The aim of the study is to compare the effect of a progressive, periodized exercise training designed to impact bone, CHD-risk-factors and menopausal complaints versus the combined effect of exercise and "phytoestrogen" (cimicifuga racemosa; CR). After randomization, 84 females 1-3 year postmenopausal with no medication or illness affecting bone metabolism exercise over 12 months (EG; 42 with, 42 without CR), 42 women serve as wellness-control. Three group training sessions/week will be performed in the EG. Both groups will be individually supplemented with calcium and Vit-D (cholecalciferol).
Magnetic resonance imaging (MRI) and echocardiography are two imaging methods that are used to obtain pictures of the heart and assess heart function. This study will evaluate a new, four-dimensional echocardiography approach of obtaining heart images to determine if it is as effective at evaluating heart function as MRI.
The purpose of this study is to test the hypothesis of whether contrast enhanced Magnetic Resonance Imaging can be used to predict improvement of the wall motion in regions of the heart with abnormal movement following bypass surgery or percutaneous angioplasty in various institutions across three continents.
The purpose of this study is to determine whether a 6 month duration of clopidogrel therapy after DES implantation is not inferior to that of a 12 month therapy.
In an observational multi-centre study (HEROS), the effects of starting treatment with rosuvastatin were assessed, on low-density lipoprotein cholesterol (LDL-C) goal achievement, in patients with a dissimilar high-risk profile who had not been treated with cholesterol lowering drugs at least in the past three months. Also set-up costs of rosuvastatin treatment and proportional changes in LDL-C and high-density lipoprotein cholesterol (HDL-C) were studied.
Fifty patients will be enrolled into the study. The purpose of the study is to investigate the relevance of Hct levels in determining need for transfusion during operations employing bypass as well as to test the hypothesis that, while HCt levels may decrease during surgery , red blood cell mass and tissue oxygenation remain fairly constant.
Randomized clinical comparison of the serolimus eluting Cypher stent and the zotarolimus eluting Endeavor stent.
This study will evaluate the potential of RO4607381 to reduce cardiovascular morbidity and mortality in stable coronary heart disease patients with recent Acute Coronary Syndrome (ACS) and evaluate the long term safety profile of the drug. Eligible patients in stable condition will be randomized to receive either RO4607381 600mg po or placebo po, daily, together with a background of standard medication for ACS (including aspirin, antihypertensives and statins). The anticipated time on study treatment is 2+ years, and the target sample size is 15,600 individuals.
The purpose of this study is to determine whether treatment with 40mg of Rosuvastatin for 8 weeks will reduce the number of episodes of myocardial ischaemia suffered in subjects with coronary artery disease.
