Pharmacologic management of chronic heart failure (HF) is primarily determined by the patient's left ventricular ejection fraction (LVEF) and severity of symptoms. Patients with chronic HF who have an LVEF ≤40% are considered to have heart failure with reduced ejection fraction (HFrEF) and those with an LVEF ≥50% are considered to have heart failure with preserved ejection fraction (HFpEF). Patients with an LVEF of 41-49% have heart failure with mildly reduced or mid-range ejection fraction.

Aliskiren (ah LIS ker in; Tekturna - Novartis), the first direct renin inhibitor, has been approved by the FDA for treatment of hypertension. It is indicated for oral use either as monotherapy or in combination with other antihypertensive agents.
