Advances in the epidemiology of heart failure and left ventricular remodeling.

Heart failure (HF) continues to impose a major public health burden.1 Whereas considerable improvements in HF treatment have resulted from clinical trials, epidemiological investigations complement clinical trials by enhancing our ability to identify individuals at risk and, in turn, facilitate the development of interventions aimed at the primary prevention of HF. Accordingly, there have been several noteworthy advances to date in the epidemiology of heart failure and subclinical myocardial disease, which are summarized below.
