Mean longitudinal systolic velocity and longitudinal strain increased by 7 % and 14 % on indapamide ( from 5.6 1.8 to 6.0 1.1 cm/s and from 16.2 % 1.8 % to 18.5 % 1.1 % , both P < .05 ) , but did not change on hydrochlorothiazide ( P < .05 for intergroup differences ) , whereas ejection fraction and radial systolic function did not change .
