ABSTRACT
PURPOSE--To evaluate the effects of the use of chlorthalidone on left ventricular mass of patients with mild and moderate systemic arterial hypertension (SAH). METHODS--Twenty-nine patients with mild and moderate SAH were studied with mean age of 48.4 years and 16 men. Clinical evaluation, systolic (SBP) and diastolic (DBP) blood pressure and heart rate (HR), in supine and standing positions, were obtained before and every 3 weeks, after 2 with placebo, during 12 weeks of treatment with 50mg of chlorthalidone each 48 hours. Laboratory data (hemogram, sodium, potassium, urea creatinine, glucose, hepatic aminotransferases and urinalysis) were done before and at end of study. Echocardiographic study was performed by M-mode before and after 6 and 12 weeks of treatment, and obtained the following data diastolic diameter (DdLV), diastolic septum (DSTLV) and posterior wall thickness (PWTLV) of left ventricle. The left ventricular mass (LVM) was calculated by the formula LVM = (DSTLV+PWTLV+DdLVE)3 - (DdLV)3 x 1.05/body surface, in g/m2. RESULTS--A significant reduction of SBP (p < 0.0001), DBP (p < 0.001) in supine and standing positions. HR did not show statistical difference. At echocardiographic study, M-mode, was observed a significant reduction of LVM after 12 weeks of treatment (181 +/- 67 to 156 +/- 34 g/m2, p < 0.01). CONCLUSION--Chlorthalidone was effective to control blood pressure and to reduce LVM of patients with SAH.
