There have been no studies of the possibility of reversing the left ventricular hypertrophy (LVH) of chronically hemodialyzed hypertensive uremics (HDH) with long-term antihypertensive therapy. We have measured left ventricular sizes of eight (6 male, 2 female, aged 29 to 61 years) HDH with M-mode echocardiography, before and 12, 18 and 24 months after the start of a combined antihypertensive therapy which included ACE-inhibitors, beta-blockers and calcium-antagonists. Pre-treatment values for mean blood pressure (MBP), 116.6 +/- 2.9 mm Hg, end diastolic diameter (EDD), 62.6 +/- 6.6 mm, interventricular septum (IVS), 14.2 +/- 3.0 mm, and left ventricular mass index (LVMi), 239 +/- 61 g/m2, were all significantly higher than those for nine sex- and age-matched hemodialyzed normotensive subjects (HDN) with comparable hemoglobin (Hb) levels. During the antihypertensive treatment, both the systolic and diastolic BP decreased steadily (P = 0.0001; P = 0.0003; ANOVA) and significantly by the third month (P < 0.05; P < 0.01), reaching levels comparable to those of the HDN group after 12 months. At this time the LVMi (204 +/- 67) and the IVS (13.1 +/- 2.7), although both significantly lower than baseline, were still higher than in the HDN group, while the EDD was similar. After 24 months, however, both the IVS (12.3 +/- 3.1) and the LVMi (161 +/- 65) were no longer different from those of the HDN group.(ABSTRACT TRUNCATED AT 250 WORDS).
