Left atrial compliance index predicts exercise capacity in patients with heart failure and preserved ejection fraction irrespective of right ventricular dysfunction

Background and Aim Predictors of exercise capacity in heart failure ( HF ) with preserved ejection fraction ( HF p EF ) remain of difficult determination. The aim of this study was to identify predictors of exercise capacity in a group of patients with HF p EF and right ventricle ( RV ) dysfunction Methods In 143 consecutive patients with HF p EF (age 62 ± 9 years, LV EF ≥45) and 41 controls, a complete echocardiographic study was performed.
