Echocardiography is the most performed imaging modality to evaluate heart failure patients. Right ventricular (RV) systolic dysfunction is a major prognostic factor.

Evaluate the prevalence of RV systolic dysfunction in heart failure patients with reduced LVEF as well as their clinical, electrical and echocardiographic profile and prognosis.

Retrospective and descriptive study collecting heart failure patients with reduced LVEF during a period of 5 months (between October 2017 and February 2018).

Our population was divided into 2 groups, the group 1 has a normal RV function and the group 2 has an RV systolic dysfunction defined as TAPSE using M mode imaging of less than 15mm and systolic velocity S’ of lateral tricuspid annulus using tissue Doppler imaging of less than 9.5cm/s. Then, were studied clinical, electrical and echocardiographic characteristics of each group.

Statistical analysis was performed using SPSS 2.0 software.

One hundred and four patients were collected. The group 1 is made of 83 patients (79.8%), 42.2% are diabetic, 45.8% are hypertensive, 4.8% are dyslipidemic, 33.7% are smokers, 26.5% are class I NYHA, 60.2% class II NYHA, 13.3% class III NYHA, no patient is class IV NYHA, 7.2% in atrial fibrillation, mean LVEF is of 35% and mean systolic pulmonary artery pressure is of 45mmHg. The group 2 is made of 21 patients (20.2%), 33.3% are diabetic, 42.9% are hypertensive, 4.8% are dyslipidemic, 57.1% are smokers, 9.5% in class I NYHA, 57.1% in class II NYHA, 28.6% in class II NYHA, 4.8% in class IV NYHA, 33.3% are in atrial fibrillation, mean LVEF is of 27%, all patients are in pulmonary artery hypertension and mean systolic pulmonary artery pressure is of 45mmHg.

In heart failure with reduced LVEF, RV systolic dysfunction is a prognostic factor. Actually, RV free wall strain gives the most accurate prognostic value.
