Heart failure is a significant global public health concern with considerable morbidity and mortality. Estimates suggest that approximately 23 million people are affected by heart failure. Approximately 50% of heart failure cases are heart failure with reduced ejection fraction (HFrEF). HFrEF arises when the left ventricular ejection fraction (LVEF) is ≤ 40% and is accompanied by progressive left ventricular dilatation and adverse cardiac remodeling. Following a hospitalization for HFrEF, the 5-year mortality rate can be as high as 75%, particularly among older adults, which highlights the need for effective treatment.
