Sociodemographic, Clinical Condition, and Functional Aerobic Capacity in Patients With Heart Failure With Varying Ventricular Ejection Fraction

209 patients with heart failure (HF) entering a cardiac rehabilitation program, including HFpEF (LVEF ≥50%, n=70), HFmrEF (LVEF 40-49%, n=69), and HFrEF (LVEF <40%, n=70). Mean age 62.7, 67.5% male, based in Colombia. Key exclusions: NYHA functional class IV, physical limitations for active movements, respiratory comorbidities (COPD, asthma), and decompensated HF at admission.

Differences in sociodemographic, clinical, functional aerobic capacity (STS, 6MWT), and health-related quality of life (DASI, MLFHQ, PHQ-9) variables across LVEF groups
