    ABSTRACT: Right ventricular (RV) function impacts the outcome in cardiac and pulmonary diseases such as heart failure, pulmonary hypertension, myocardial infarction, valvular, and congenital heart diseases. To our knowledge, simultaneous evaluation of left ventricular (LV) and RV systolic and diastolic echocardiographic indices in outpatients with clinically stable cardiovascular diseases has never been performed. Thus, we designed a prospective cohort study to define the prognostic power of these parameters. One hundred and sixty-three patients were submitted to transthoracic echocardiography with multiparametric and tissue Doppler evaluation of the following indices: ejection fraction, MAPSE, TAPSE, RV presystolic peak, LV and RV diastolic function, pulmonary artery systolic pressure, and functional mitral regurgitation. All these parameters and clinical variables (age, sex, and prior cardiovascular events) were entered in a multivariable Cox regression model. The primary end point was the occurrence of major cardiovascular events (MACEs) during the follow-up period. Twenty-one MACEs were observed; in the final multivariable Cox regression model only prior cardiovascular events (B 1.305, p 0.004, 95% CI 1.523-8.933), age (B 0.067, p 0.005, 95% CI 1.020-1.121), and TAPSE (B -1.065, p 0.026, 95% CI 0.135-0.883) were associated with MACEs. TAPSE, a simple and reproducible echocardiographic index, may be viewed as an early echocardiographic marker of heart involvement in atherosclerosis. We believe that TAPSE may be useful in clinical practice for risk stratification.
