Patients with documented left ventricular ejection fraction (LVEF) ≥ 50% are considered to have heart failure (HF) with preserved ejection fraction (HFpEF) (1). While HFpEF accounts for ~ 50% of patients with HF globally, it accounts for 15%–20% of patients with HF in India (2). HFpEF is characterized by increased left ventricular filling pressures and/or reduced cardiac output either at rest or on exertion. The body maintains the cardiac output by abnormally increasing the
