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.

Comparative StudyReadmission rates for Hispanic Medicare beneficiaries with heart failure and acute myocardial infarction.
Hispanics are the fastest growing segment of the US population and have a higher prevalence of cardiovascular risk factors than non-Hispanic whites. However, little is known about whether elderly Hispanics have higher readmission rates for heart failure (HF) and acute myocardial infarction (AMI) than whites and whether this is due to site of care. ⋯ Elderly Hispanic patients are more likely to be readmitted for HF and AMI than whites, partly due to the hospitals where they receive care. Our findings suggest that targeting the site of care and these high-risk patients themselves will be necessary to reduce disparities in readmissions for this growing group of patients.
