AIM: Aim of this study was to better understand interactions between left ventricular (LV) and right ventricular (RV) systolic and diastolic function echocardiographic indexes in stable cardiovascular diseased patients and in subjects with cardiovascular risk factors.
METHODS: The study enrolled 683 stable patients who were submitted to standard transthoracic echocardiography with evaluation of left ventricular ejection fraction (LVEF) (Simpson biplane method), LV and RV systolic peak on Doppler tissue imaging (LVSys and RVSys), tricuspid annulus plane systolic excursion (TAPSE), pulmonary artery systolic pressure (PASP), and multiparameter evaluation of LV and RV diastolic function utilizing E and A peak, their ratio, E peak deceleration time, E’ and A’ peak on Doppler tissue imaging, their ratio, and E/E’ ratio.
RESULTS: Part of the considered indexes had interactions but only LVEF and TAPSE were related to all the others (LVEF P<0.001 with all the considered parameters; TAPSE P<0.001 with all parameters except with PASP=0.003). Unexpectedly TAPSE seems to have, such as LVEF, a pivotal position among LV and RV function.
CONCLUSION: The study demonstrates the existence of interactions between LV and RV function indexes; these results may be considered as a piece of evidence in favor of heart seen as a single structure.
