Key result

ACC/AHA HF stages classify patients by risk to guide prevention and therapy escalation.

Key Points

To synthesize the ACC/AHA heart failure staging framework and delineate how its classification guides stage-matched prevention, early intervention, and treatment escalation.
Reviewed the expert-consensus staging framework adapted from the 2001 and 2022 ACC/AHA heart failure guidelines.
Characterized diagnostic criteria for Stages A through D using clinical risk profiles, echocardiography, hemodynamic parameters, and cardiac biomarkers including BNP and cardiac troponin.
Stage A categorizes patients with clinical risk factors but no structural or biomarker changes, whereas Stage B identifies preclinical disease defined by structural anomalies, elevated filling pressures, or abnormal biomarkers without symptoms.
Stage C defines patients with past or active heart failure symptoms requiring foundational guideline-directed medical therapy, while Stage D reflects advanced refractory disease requiring specialized interventions such as ventricular assist devices or transplantation.
Staging reflects irreversible disease progression rather than dynamic functional severity, serving as a longitudinal complement to the New York Heart Association functional classification.

Supports stage-based HF risk stratification; leaves open prospective validation of tailored interventions.

Abstract

The ACC/AHA Heart Failure Stages categorize patients based on risk and disease progression, from preclinical risk to advanced heart failure. The system links each stage to guideline-directed management, emphasizing prevention, early intervention, and escalation of therapy.
