Cardiopulmonary Exercise (HF) Risk Score Calculator

Cardiopulmonary Exercise (HF) Risk Score: Explanation and Clinical Context The Cardiopulmonary Exercise (HF) Risk Score is a validated tool for assessing prognosis in patients with chronic heart failure based on cardiopulmonary exercise testing (CPX) parameters. It incorporates age, peak oxygen uptake (Peak VO₂), ventilatory efficiency (VE/VCO₂ slope), and history of heart failure hospitalization. Higher scores indicate worse functional capacity, impaired ventilatory response, or prior clinical events, correlating with increased risk of adverse outcomes.

The total score stratifies patients into low, intermediate, or high risk, guiding clinicians in individualized management, treatment planning, and consideration for advanced therapies or transplant evaluation.
