The estimated risk in heart failure patients (HF) is crucial for the therapeutic strategy. Right ventricular function (RF) predicted exercise capacity in these patients. The systolic excursion of the tricuspid annulus (TAPSE) has been described as a single endpoint that RV function. The aim of our study is to demonstrate the relationship between TAPSE and left ventricular ejection fraction (LVEF) on one hand and in the other hand TAPSE and exercise capacity in people with HF. Our study included 30 HF patients, defined as an LVEF estimated by Simpson biplane≤45%. Echocardiography and a 6min walk test (6MWT) were performed on the same day for all patients. Pearson analysis used to assess the relationship between variables. A P-value<0.05 was considered statistically significant. The mean age of our patients was 58.3±13years. Sixteen patients (53%) had ischemic Hf. Twenty-two patients (73%) were in NYHA class II and 7 were in class III. The mean LVEF was 37±5%. The average distance walked in 6MWT was 393±135m. The average value of TAPSE was 18±3mm. Six patients (20%) had TAPSE<16mm. TAPSE was correlated significantly with LVEF (r=0.36; P=0.049) and with distance walked in the 6MWT (r=0.43; P=0.02). Right ventricular systolic function, as assessed by TAPSE, has important prognostic value in chronic heart failure patients. It is both correlated to systolic LV function and physical performance of these patients.
