Patients with hypertension have different types of left ventricular (LV) geometry, but the impact of blood pressure (BP) reduction on LV geometry change during antihypertensive treatment remains unclear.


Two-dimensional and M-mode echocardiograms were recorded at baseline in 853 unmedicated patients with stage II to III hypertension and LV hypertrophy determined by electrocardiography (Cornell voltage duration > or =2440 mV x ms or modified Sokolow-Lyon criteria: SV1 + RV5/RV6 >38 mV) after 14 days of placebo treatment. Follow-up echocardiography was done after 1 year of blinded treatment with either losartan or atenolol, in some cases supplemented with thiazide and calcium antagonist to reach target a BP of 140/90 mm Hg.


Baseline systolic/diastolic BP were reduced from 174 +/- 20/95 +/- 11 to 151 +/- 19/84 +/- 11 mm Hg. LV mass was reduced from 234 +/- 56 to 207 +/- 51 g and relative wall thickness from 0.41 +/- 0.07 to 0.38 +/- 0.06 (all P <.001). Prevalence of concentric LV hypertrophy decreased from 24% to 6%, eccentric LV hypertrophy from 46% to 37%, and concentric LV remodeling from 10% to 6%; normal geometry increased from 20% to 51%. A shift toward lower LV mass and relative wall thickness was found, as approximately 73% of those with concentric LV remodeling at baseline shifted to normal geometric pattern, whereas only 7% of those with normal pattern at baseline shifted to concentric LV remodeling. Of patients with concentric LV hypertrophy at baseline, 34% shifted to eccentric LV hypertrophy, whereas only 3% with eccentric LV hypertrophy at baseline had concentric LV hypertrophy. Furthermore, multiple regression analysis showed that Doppler stroke volume reduction was a significant correlate of LV mass reduction (beta = 0.108, P <.001) independent of BP, heart rate change, and assigned drug treatment.


Antihypertensive treatment reduces LV mass and decreases the prevalence of LV hypertrophy and concentric LV remodeling. Additional control of Doppler stroke volume potentiates the effect of BP reduction on LV mass regression independent of the BP reduction per se.
