Correlation between Left Ventricular End-diastolic Pressure and Peak Left Atrial Wall Strain during Left Ventricular Systole

Left atrial (LA) reservoir function is determined by integration of LA relaxation and left ventricular (LV) systolic function, and LV diastolic dysfunction increases LA volume at end systole. This study investigates the effect of LV end-diastolic pressure on LA wall tension during LV systole.A total of 101 stable patients with sinus rhythm undergoing cardiac catheterization were studied. LA wall extension during LV systole was evaluated as LA...
