Identified predictors may aid 6-MWT estimation in HFrEF; leaves open prospective validation before substituting for direct testing.

Do echocardiographic parameters predict poor 6-minute walk test performance in patients with heart failure and reduced LVEF?
Odds Ratio: 0.076 (95% CI 0.017–0.335)
p-value: p=0.001
Echocardiographic markers of right ventricular dysfunction, elevated LV filling pressures, and dyssynchrony can independently predict poor exercise capacity in HFrEF patients.
Pranvera Ibrahimi (2015) conducted a cross-sectional in Heart failure with reduced left ventricular ejection fraction (n=111). Echocardiographic parameters (TAPSE, E/e', t-IVT) was evaluated on Poor 6-minute walk test performance (≤300m) (OR 0.076, 95% CI 0.017-0.335, p=0.001). In patients with heart failure, TAPSE (OR 0.076; 95% CI 0.017-0.335; p=0.001), E/e', and t-IVT independently predicted poor 6-minute walk test performance (≤300m).
