    Abstract:
    This study was designed to compare the antihypertensive efficacy of nitrendipine and atenolol in young and middle-aged patients with mild or moderate essential hypertension and to assess treatment effects on plasma lipids and potential changes in left ventricular mass (LVM). After 2 weeks off medication and a 4-week placebo phase, patients who met the inclusion criteria [sitting diastolic blood pressure (DBP) 95 to 114 mm Hg, age below 50 years] entered a 12-week dose-adjustment and maintenance period with nitrendipine or atenolol. Serum lipids were determined before and after therapy. At the same time, LVM was evaluated echocardiographically (M mode). Twenty-two patients completed the double-blind, randomized study. After 12 weeks on nitrendipine, the systolic blood pressure (SBP) and DBP were reduced (p less than 0.005 and p less than 0.001, respectively). No significant changes in heart rate were observed. There were no changes in the lipid profile, and LVM was reduced from 93.7 to 23.4 to 82.4 +/- 22.6 g/m2 of body surface (p less than 0.05). On atenolol the SBP and DBP were reduced (p less than 0.001 and p less than 0.001, respectively). The expected reduction in heart rate was significant (p less than 0.05). Total cholesterol and LDL cholesterol increased by 11% (p less than 0.05) and 12.3% (p less than 0.01), respectively. HDL cholesterol showed a small reduction. Tryglycerides increased by 22% (n.s.). LVM did not change. In conclusion, nitrendipine and atenolol showed comparable antihypertensive efficacy.(ABSTRACT TRUNCATED AT 250 WORDS)
