CHAMPION HF Risk Algorithm (Prototype)

CHAMPION HF Risk Algorithm (Prototype) — explanation and clinical context This page provides a prototype, point-based risk stratification tool informed by variables central to pulmonary artery pressure-guided heart failure management (age, NYHA class, prior HF hospitalization, mean pulmonary artery pressure, LVEF, renal function, and NT-proBNP). The CHAMPION randomized trial evaluated the CardioMEMS pulmonary artery pressure monitoring system and demonstrated reductions in HF hospitalizations when clinicians had access to daily pulmonary artery pressure data. Contemporary multisensor/device algorithms (e.g., multisensor/HeartLogic approaches) and registry/post-approval analyses support the utility of hemodynamic and device-derived signals to detect impending decompensation earlier than symptoms alone.

This prototype does not reproduce any published CHAMPION 'risk equation' (no public, peer-reviewed set of regression coefficients labelled "CHAMPION HF Risk Algorithm" was identified). Instead, the tool presents a transparent heuristic mapping of common risk markers to a tiered short-term risk estimate for educational/demo use only.
