Randomized Controlled Trial Multicenter Study Comparative StudyColchicine prevents early postoperative pericardial and pleural effusions.
No preventive pharmacologic strategies have been proven efficacious for the prevention of postoperative effusions after cardiac surgery. Colchicine is safe and efficacious for the prevention of pericarditis. On this basis, we realized a substudy of the COPPS trial to assess the efficacy and safety of colchicine for the prevention of postoperative pericardial and pleural effusions. ⋯ Colchicine is safe and efficacious for the primary prevention of postoperative effusions after cardiac surgery.

Multicenter Study Comparative Study Clinical TrialBerlin Heart EXCOR Pediatric ventricular assist device Investigational Device Exemption study: study design and rationale.
Currently, there are no Food and Drug Administration-approved devices available that can provide long-term mechanical circulatory support to smaller children with severe heart failure as a bridge to heart transplant (HT). In recent years, the Berlin Heart EXCOR Pediatric ventricular assist device (VAD) has emerged as a potential treatment option. Systematic data on the safety and efficacy of the EXCOR are limited. ⋯ The Berlin Heart IDE clinical study will be the first bridge-to-HT VAD study designed exclusively for children. It is anticipated that the study will provide important information on the safety and efficacy of the Berlin Heart EXCOR Pediatric in children while providing valuable lessons into the design and conduct of future VAD studies in children.

Multicenter Study Comparative StudyThe CHADS2 score predicts ischemic stroke in the absence of atrial fibrillation among subjects with coronary heart disease: data from the Heart and Soul Study.
We sought to evaluate the prognostic performance of the CHADS(2) score for prediction of ischemic stroke/transient ischemic attack (TIA) in subjects with coronary heart disease (CHD) without atrial fibrillation (AF). ⋯ The CHADS(2) score predicts ischemic stroke/TIA in subjects with stable CHD and no baseline AF. The event rate in non-AF subjects with high CHADS(2) scores (5-6) was comparable with published rates in AF patients with moderate CHADS(2) scores (1-2), a population known to derive benefit from stroke prevention therapies. These findings should inform efforts to determine whether stroke prevention therapies or screening for silent AF may benefit subjects with stable CHD and high CHADS(2) scores.

Randomized Controlled Trial Multicenter Study Comparative StudyRapid complete reversal of systemic hypoperfusion after intra-aortic balloon pump counterpulsation and survival in cardiogenic shock complicating an acute myocardial infarction.
In patients with cardiogenic shock (CS) complicating an acute myocardial infarction, a strategy of early revascularization (ERV) versus initial medical stabilization (IMS) improves survival. Intra-aortic balloon counterpulsation (IABC) provides hemodynamic support and facilitates coronary angiography and revascularization in CS patients. ⋯ In CS patients, CRH after commencing IABC was independently associated with improved in-hospital, 30-day and 1-year survival regardless of early revascularization. In CS patients, CRH with IABC is an important early prognostic feature.

Randomized Controlled Trial Multicenter Study Comparative StudyRationale and design of dal-PLAQUE: a study assessing efficacy and safety of dalcetrapib on progression or regression of atherosclerosis using magnetic resonance imaging and 18F-fluorodeoxyglucose positron emission tomography/computed tomography.
dal-PLAQUE is a placebo-controlled multicenter study designed to assess the effect of dalcetrapib on imaging measures of plaque inflammation and plaque burden. dal-PLAQUE is a multimodality imaging study in the context of the large dal-HEART Program. Decreased high-density lipoprotein cholesterol is linked to increased risk of coronary heart disease (CHD). Dalcetrapib, a compound that increases high-density lipoprotein cholesterol by modulating cholesteryl ester transfer protein, is being studied to assess if it can reduce the progression of atherosclerotic disease and thereby decrease cardiovascular morbidity and mortality. ⋯ A tertiary objective is to examine the dynamic contrast-enhanced MRI parameters of plaque neovascularization. In total, 189 subjects entered screening, and 130 were randomized. dal-PLAQUE will provide important information on the effects of dalcetrapib on markers of inflammation and atherosclerotic plaque burden and, thereby, on the safety of cholesteryl ester transfer protein modulation with dalcetrapib. Results are expected in 2011.
