Filter by:The purpose of the ISCHEMIA trial is to determine the best management strategy for higher-risk patients with stable ischemic heart disease (SIHD). This is a multicenter randomized controlled trial with 5179 randomized participants with moderate or severe ischemia on stress testing. A blinded coronary computed tomography angiogram (CCTA) was performed in most participants with eGFR ≥60 mL/min/1.73m2 to identify and exclude participants with either significant unprotected left main disease (≥50% stenosis) or those without obstructive CAD (<50% stenosis in all major coronary arteries). Of 8518 participants enrolled, those that had insufficient ischemia, ineligible anatomy demonstrated on CCTA or another exclusion criterion, did not go on to randomization. Eligible participants were then assigned at random to a routine invasive strategy (INV) with cardiac catheterization followed by revascularization, if feasible, plus optimal medical therapy (OMT) or to a conservative strategy (CON) of OMT, with cardiac catheterization and revascularization reserved for those who fail OMT. SPECIFIC AIMS A. Primary Aim The primary aim of the ISCHEMIA trial is to determine whether an initial invasive strategy of cardiac catheterization followed by optimal revascularization, if feasible, in addition to OMT, will reduce the primary composite endpoint of cardiovascular death, nonfatal myocardial infarction, resuscitated cardiac arrest, or hospitalization for unstable angina or heart failure in participants with SIHD and moderate or severe ischemia over an average follow-up of approximately 3.5 years compared with an initial conservative strategy of OMT alone with catheterization reserved for failure of OMT. B. Secondary Aims Secondary aims are to determine whether an initial invasive strategy compared to a conservative strategy will improve: 1) the composite of CV death or MI; 2) angina symptoms and quality of life, as assessed by the Seattle Angina Questionnaire; 3) all-cause mortality; 4) net clinical benefit assessed by including stroke in the primary and secondary composite endpoints; and 5) individual components of the composite endpoints.

The primary objective is to establish the safety of the CO-rebreathing method for measuring total blood and plasma volume in CAD patients. The working hypothesis is that the CO-rebreathing method is safe in use with coronary artery disease patients and that it does not cause myocardial ischemia or cardiovascular damage.
Tai chi intervention may lead to relaxation and could potentially reduce the risk of cardiovascular disease. This project entails a comprehensive and innovative approach for understanding, measuring, and potentially reducing cardiovascular risk in women. The goal of this area of research is to reduce cardiovascular risk and perhaps reduce illness and death.
This project will evaluate the effects of World Trade Center (WTC) exposure in WTC responders 10-13 years following the events of 9/11. Prior studies have described persistent pulmonary function abnormalities in a significant portion of responders. The investigators study seeks to examine the relationship between pulmonary function abnormalities and other markers of chronic cardiopulmonary disease and further elucidate the pathophysiologic effects of exposure to inhaled particulate matter (PM) on 9/11. This study will provide critical information regarding risk of exposure to PM, risk factors for disease and potential for improvements in diagnosis and treatment.
The Finnish Vitamin D Trial (FIND) is a randomized, double-blind, placebo-controlled, 5-year supplementation study of the benefits and risks of vitamin D in the primary prevention of cardiovascular (CVD) and cancer among 18000 men 60 years or older and women 65 years or older. [Edit 25.3.2015: Due to difficulties in recruitment and funding, the study size is approximately 2500 subjects, with a 550 subject subgroup with more detailed examinations] The participants will be randomized to 3 groups with 6000 in each, with daily supplementation of either: 1) 40 µg/day (1600 IU) of vitamin D3, 2) 80 µg/day (3200 IU) of vitamin D3, or 3) placebo. [Edit 15.3.2015: The 2500 subjects are randomized in 3 groups, approximately 830 subjects per group.] Compliance, use of non-study drugs or supplements, diet, development of endpoints, and CVD and cancer risk factors will be assessed by questionnaires. Blood samples will be collected for assessment of effect modification by baseline 25-hydroxyvitamin D, as well as for future ancillary studies of genetic/biochemical hypotheses. Event data will be obtained by record linkage from the national computerized hospitalization registry.
A randomized double blind controlled trial was conducted to evaluate the effect of daily supplementation with soy isoflavone 100 mg/day for 12 months on 182 postmenopausal women aged 47 to 60 years at subdistrict South Jakarta Indonesia. The study hypothesis was supplementation soy isoflavone 100 mg/day for 6 and 12 months can increase endothelial function.
Atherogenic dyslipidemia includes patients who have coronary heart disease (CHD) or CHD risk equivalents, whose TG level is not adequately controlled after statin monotherapy. According to the published ESC/EAS consensus, fibrate is suggested to be added to this type of patient who has insufficient improvement. The purpose of the study is to evaluate the efficacy on lipid control and the safety of adding fenofibrate in patients on a background of statin treatment.
OBJECTIVE OF THE STUDY: To test the hypothesis that 6 months DAPT (Dual anti-platelet therapy) after second generation DES (Drug Eluting Stent) implantation in STEMI (ST elevation Myocardial Infarction) is not inferior to 12 months DAPT in terms of clinical outcomes (composite endpoint of all-cause mortality, any MI, any revascularization, stroke and major bleeding at 18 months after randomization). The trial will incorporate two registers studying respectively the safety outcomes of Bivalirudin and Prasugrel combination and Bivalirudin and Ticagrelor combination at 2 and 30 days. Finally the trial design permits assessment of the clinical outcomes after primary PCI for treatment of STEMI with the new Resolute Integrity (Medtronic Santa Rosa Ca, USA) stent at 30 days and 6 months.
The purpose of this study is to evaluate the effectiveness of a brazilian cardioprotective diet plan to reduce cardiovascular risk factors of new cardiovascular events.
The purpose of this study is to investigate whether a nurse-based intervention, consisting of structural informative consulting and motivational counseling, on top of usual care with or without personalized web-based visualization of cardiovascular risk levels, improves the medication adherence in high risk cardiovascular patients.
