Abstract/OtherAbstract:
BACKGROUND: Right brachial pre-ejection period (rbPEP), brachial-ankle pulse wave velocity (baPWV), and right brachial ejection time (rbET) can be automatically determined from an ABI-form device. The aims of this study are to test the applicability of baPWV-derived myocardial performance index (MPI) (defined as the ratio of rbPEP divided by its own s.d. + baPWV divided by its own s.d. to rbET divided by its own s.d.) as an indicator of combined left ventricular (LV) systolic and diastolic functions.
METHODS: A sum of 215 patients were consecutively included. The rbPEP, baPWV, and rbET were measured using an ABI-form device and LV function was determined by echocardiography.
RESULTS: After a multivariate analysis, diastolic blood pressure (beta = 0.220, P < 0.001), LV ejection fraction (LVEF) (beta = -0.291, P < 0.001), transmitral E wave velocity (E) (beta = -0.106, P = 0.032), early diastolic mitral annular velocity (Ea) (beta = -0.142, P = 0.009), and ET obtained by tissue Doppler echocardiography (beta = -0.397, P < 0.001) were the major determinants of baPWV-derived MPI. The area under the curve for rbPEP, baPWV, rbET, rbPEP/rbET, and baPWV-derived MPI in prediction of Ea <8 cm/s, E/Ea >10, or LVEF <50% were 0.69, 0.76, 0.67, 0.73, and 0.83, respectively.
CONCLUSIONS: BaPWV-derived MPI had a significant correlation with echocardiographic LV diastolic and systolic function. It may be a novel and feasible indicator in assessment of global LV function.
