AimsTo evaluate whether the clinical and echocardiographic correlates and the prognostic significance of right ventricular (RV) dysfunction are different in heart failure patients with reduced (HFrEF), mid-range (HFmrEF), or preserved (HFpEF) left ventricular ejection fraction. Methods and resultsThe study included 1663 patients with heart failure caused by ischaemic or hypertensive heart disease or by idiopathic cardiomyopathy. Left ventricular ejection fraction was <40% in 1123 patients (HFrEF), 40-49% in 156 patients (HFmrEF) and 50% in 384 patients (HFpEF). Imaging of the right ventricle was performed by echocardiography; RV function was defined on the basis of tricuspid annular plane systolic excursion (TAPSE) and its normalization for pulmonary artery systolic pressure (PASP). All-cause mortality was the endpoint of survival analysis. Non-sinus rhythm, high heart rate, ischaemic aetiology and E-wave deceleration time <140ms were associated with a reduced TAPSE in HFrEF patients, whereas PASP >40mmHg was by far the strongest correlate of a reduced TAPSE in HFpEF and HFmrEF patients (interaction analysis, P=0.0011). TAPSE/PASP proved to be a powerful predictor of prognosis in all patients. ConclusionsThe correlates of RV dysfunction differ in HFrEF compared with HFpEF and HFmrEF patients. Regardless of the extent of LV dysfunction, the TAPSE/PASP ratio is a powerful independent predictor of prognosis in all heart failure patients.
