Effects of anti-hypertensive therapy on serum lipoproteins. Treatment with metoprolol, propranolol and hydrochlorothiazide.
The effects of metoprolol, propranolol and hydrochlorothiazide on lipoprotein metabolism were studied in three different but comparable groups of middle-aged men with previously untreated hypertension (n=10, n=10, and n=11, respectively). All three treatments were associated with an increase in serum triglyceride and VLDL-cholesterol levels. Propranolol treatment was associated with consistent and significant decreases in HDL-cholesterol, apoA-I and A-II levels, whereas these changes during the other treatments were neither significant nor consistent. An increase in adipose tissue LPL-activity and a decrease in serum free fatty acids were seen in the propranolol treatment group. Significant changes were not observed in glucose tolerance or catecholamine excretion. The blood pressure reduction was similar in the three groups. The design of the present study was in some important respects different from that of others. This may help to explain why we found a difference between the two beta-blockers in our study.
