Among patients with chronic heart failure, those with a left ventricular ejection fraction (LVEF) ≤40% are considered to have heart failure with reduced ejection fraction (HFrEF). Patients with a LVEF ≥50% are considered to have heart failure with preserved ejection fraction (HFpEF). Those with a LVEF of 41-49% are an intermediate group more similar to patients with HFpEF.

Anticoagulants are the drugs of choice for treatment and prevention of deep venous thrombosis (DVT) and pulmonary embolism (PE), collectively referred to as venous thromboembolism (VTE). US guidelines for treatment of VTE were updated in 2020 and 2021.
