BAG-3 Mutation Dilated Cardiomyopathy With Left Ventricular Noncompaction in Young Healthy Adult.

Cardiomyopathies are generally divided into ischemic and nonischemic types. Dilated cardiomyopathies, which are a type of nonischemic cardiomyopathy, may have a trait of left ventricular noncompaction. We present the case of a 34-year-old man with new-onset decompensated heart failure and left ventricular noncompaction from a BAG3 (Bcl-2 associated athanogene 3) truncating mutation.

Association of β-blocker exposure with outcomes in heart failure differs between African American and white patients.

Background: β-Blockers (BB) are a mainstay of heart failure (HF) treatment, yet there are inconclusive data regarding their efficacy in African American individuals.

Methods And Results: We performed a retrospective study of insured patients who received care from a large health system who were hospitalized for HF between January 2000 and June 2008 and had a documented ejection fraction <50%. BB exposure was estimated over 6-month rolling windows, using pharmacy claims data.
