Cardiac power and the association with heart failure and cardiovascular death in the general population.

Background: Cardiac power (CP) integrates echocardiographic and clinical parameters of hemodynamics, yet its prognostic value within the general population remains unexplored. This study investigated the association between CP and incident heart failure (HF) and cardiovascular (CV) death in the general population.

Methods: In this prospective cohort study, we measured CP in a total of 4022 individuals from the general population without prior HF.

Even mild mitral regurgitation is associated with incident atrial fibrillation in the general population.

Aims: Mitral regurgitation (MR) can be difficult to quantify. We sought to investigate whether the MR jet area to left atrial (LA) area ratio (MR/LA ratio) method for quantifying MRs can be used to predict incident atrial fibrillation (AF) in the general population.

Methods And Results: The study included 4466 participants from the 5th Copenhagen City Heart Study, a prospective general population study, who underwent transthoracic echocardiography.
