A randomized controlled trial of weight reduction and metoprolol in the treatment of hypertension in young overweight patients.

Abstract

The effects of weight reduction and metoprolol (100 mg, b.d.) in the treatment of hypertension (diastolic blood pressure 90-109 mmHg) in 56 young, overweight patients were investigated in a randomized placebo controlled trial. After a 4-week baseline, subjects were followed up for 21 weeks. In the weight reduction group, the fall in systolic and diastolic blood pressure (13/10 mmHg), associated with a mean group weight loss of 7.4 kg, was greater (P less than 0.001) than that in the placebo group (7/3 mmHg); the fall in diastolic pressure but not systolic pressure was also greater than that in the metoprolol group (10/6 mmHg). At the end of follow-up, 50% of the weight reduction group, 39% of the metoprolol group and 17% of the placebo group had a diastolic blood pressure of less than 90 mmHg. In the weight reduction group there was a fall in total cholesterol and the ratio of total to HDL-cholesterol (P less than 0.001); in the metoprolol group there was a fall in HDL-cholesterol and an increase in the ratio of total to HDL-cholesterol (P less than 0.001). The results suggest that in the first step of treatment for hypertension in overweight patients, modest weight reduction produces significant and clinically important reductions in blood pressure, without incurring the adverse effects on plasma lipids and lipoproteins often associated with the first step of drug therapy.
