Randomized Controlled TrialRationale and design of the coronary artery bypass grafting surgery off or on pump revascularization study: a large international randomized trial in cardiac surgery.
Uncertainty remains regarding the benefits and risks of the technique of operating on a beating heart (off pump) for coronary artery bypass grafting (CABG) surgery versus on-pump CABG. Prior trials had few events and relatively short follow-up. There is a need for a large randomized, controlled trial with long-term follow-up to inform both the short- and long-term impact of the 2 approaches to CABG. ⋯ CORONARY is the largest trial yet conducted comparing off-pump CABG to on-pump CABG. Its results will lead to a better understanding of the safety and efficacy of off-pump CABG.

Randomized Controlled TrialRationale and design of the treatment of preserved cardiac function heart failure with an aldosterone antagonist trial: a randomized, controlled study of spironolactone in patients with symptomatic heart failure and preserved ejection fraction.
Despite increasing prevalence of heart failure (HF) in patients with preserved ejection fraction (PEF), there are no available therapies proven to reduce morbidity and mortality. Aldosterone, a potent stimulator of myocardial and vascular fibrosis, may be a key mediator of HF progression in this population and is therefore an important therapeutic target. ⋯ TOPCAT is designed to assess definitively the role of spironolactone in the management of HF-PEF.

Regional differences in clinical profile, quality of care, and outcomes among Hispanic patients hospitalized with acute myocardial infarction in the Get with Guidelines-Coronary Artery Disease (GWTG-CAD) registry.
Although Hispanics constitute the largest minority in the United States, it is unknown whether regional differences in quality of care and outcomes exist among Hispanic patients hospitalized with acute myocardial infarction (MI). ⋯ Among Hispanics with acute MI enrolled in the GWTG-CAD program, there were modest regional differences in clinical profile; high rates of use and, with few exceptions, no regional differences in guideline-recommended therapies; and no regional variation in in-hospital mortality.

Randomized Controlled TrialThe fixed-dose combination drug for secondary cardiovascular prevention project: improving equitable access and adherence to secondary cardiovascular prevention with a fixed-dose combination drug. Study design and objectives.
In spite of advances in prevention and treatment, the burden of cardiovascular diseases is increasing. A fixed-dose combination (FDC) pill, or "polypill," composed of evidence-based drugs has been proposed as a means of improving cardiovascular prevention by reducing cost and increasing patient adherence to treatment. The aim of the FOCUS project, funded by the 7th Framework Programme of the European Commission, is to characterize the factors that underlie inadequate secondary prevention and to test a new FDC. ⋯ FOCUS Phase-1 will examine factors potentially related to lack of adequate secondary prevention in 4,000 post-myocardial infarction (MI) patients and analyze the relationship between these factors and patient treatment adherence. Primary end points will be (1) the percentage of patients receiving aspirin, angiotensin-converting enzyme inhibitors, and statins and (2) adherence to treatment measured by the Morisky-Green test. FOCUS Phase-2 is a randomized trial that will compare adherence to treatment in 1,340 post-myocardial infarction patients either receiving an FDC comprising aspirin (100 mg), ramipril (2.5, 5, or 10 mg), and simvastatin (40 mg) or receiving the same 3 drugs separately.

Randomized Controlled Trial Multicenter StudyRationale and design of the MASS COMM trial: A randomized trial to compare percutaneous coronary intervention between MASSachusetts hospitals with cardiac surgery on-site and COMMunity hospitals without cardiac surgery on-site.
Emergency surgery has become an increasingly rare event after percutaneous coronary intervention (PCI). There have been no randomized trials evaluating whether cardiac surgery services on-site are essential for patient safety and optimal outcomes during and after PCI. ⋯ This multicenter, randomized trial will compare the relative safety and effectiveness of nonemergency PCI at sites with and without cardiac SOS.
