Left atrial inflow propagation velocity derived by color M-mode Doppler in acute heart failure

Abstract Left atrial (LA) inflow propagation velocity from the pulmonary vein (LAIF-PV) has been proposed as a novel measure of LA reservoir function and is associated with capillary wedge pressure in critically ill patients. However, data on LAIF-PV acute heart failure (AHF) are lacking. We sought to examine feasibility measuring evaluate clinical echocardiographic correlates AHF. In prospective cohort study adults hospitalized for AHF, we used color M-mode Doppler veins obtain systole. Among 142 patients appropriate images no more than moderate mitral regurgitation, measures were feasible 76 (54%) aged 71 ± 14 years, including 68% men left ventricular ejection fraction (LVEF) 38% 13. Mean was 24.2 5.9 cm/s. multivariable regression analysis adjusted age, sex, systolic blood pressure, rate, body mass index, New York Heart Association class, volume LVEF, only independent predictors right (RV) S’ [ß 0.46 cm/s per (95% CI 0.01–0.91), p = 0.045] tricuspid annular plane excursion (TAPSE) 0.28 mm 0.02–0.54), 0.039]. Notably, not significantly correlated LV function, or E/e’. conclusion, measurable 54% lower values impaired RV but function.
