Heart failure occurs when the heart fails to pump blood at the necessary rate. It may be caused by myocardial failure but also may occur in the presence of near-normal cardiac function under conditions of high demand. An estimated 6.2 million American adults ≥ 20 years of age had heart failure between 2013 and 2016. Although prevalence is highly variable around the world, heart failure affects an estimated 64.3 million people globally, and prevalence is expected to increase as the aging population lives longer.
