Current status of heart failure: global and Korea

ABSTRACT

Heart failure (HF) is a condition in which the heart is unable to pump enough blood to meet the body’s needs for blood and oxygen. Thus, HF is a grave disease with high morbidity and mortality. Because the prevalence of and exposure to the risk factors for HF increase with age, the prevalence of HF has been increasing in an aging society, including Korea. The vast advancement of medical and device therapy has improved the outcomes of HF, but significant residual risk still exists, and the benefit is confined to patients with reduced ejection fraction. Finding effective treatment for HF with preserved ejection fraction and identification of groups who benefit from drug and device therapy remain challenging. In this review, we illustrate the epidemiology, temporal trends, and current status of medical and device therapy, including heart transplantation, as well as emerging treatments for HF in Korea and worldwide.
