Abstract Background The relationships of left ventricular (LV) longitudinal and circumferential systolic dysfunction with diastolic performance in hypertensive patients have never been compared. Methods and Results In 532 asymptomatic hypertensive patients, circumferential function was assessed with the use of midwall fractional shortening (mFS) and stress-corrected mFS (SCmFS), whereas longitudinal function was assessed with the use of left atrioventricular plane displacement (AVPD) and systolic mitral annulus velocity (s′). Early diastolic annular velocity (e′) and the E/e′ ratio were measured. Global longitudinal and circumferential strain were determined in a subset of 210 patients. e′ was linearly related to all systolic indexes (AVPD: R  = 0.40; s′: R  = 0.39; mFS: R  = 0.16; SCmFS: R  = 0.17; all P
