    Summary
    This summary is machine-generated.

    Pindolol, a beta-blocker, showed minimal impact on lipid metabolism in hypertensive patients over twelve months. Unlike other beta-blockers, it maintained stable triglycerides and fatty acids, with a significant increase in HDL-cholesterol ratio.

    Area of Science:

    • Cardiology
    • Pharmacology
    • Metabolic Research

    Background:

    • Beta-blockers can negatively affect lipid profiles, increasing cholesterol and triglycerides while decreasing HDL-cholesterol.
    • Some beta-blockers with intrinsic sympathomimetic activity may have a more favorable lipid profile.
    • Pindolol is a beta-blocker with weak intrinsic sympathomimetic activity.

    Purpose of the Study:

    • To investigate the long-term effects of pindolol on lipid metabolism in hypertensive patients.
    • To compare the lipid profile changes induced by pindolol with those of other beta-blockers.

    Main Methods:

    • Twelve-month treatment of hypertensive patients with pindolol.
    • Monitoring of serum lipid parameters including total cholesterol, triglycerides, HDL-cholesterol, free fatty acids, apolipoproteins, and lecithin cholesterol acyl-transferase activity.

    Main Results:

    • Serum free fatty acids and triglycerides remained stable throughout the twelve-month treatment.
    • HDL-cholesterol levels increased after one month but showed no significant difference at later time points.
    • The ratio of HDL-cholesterol to total cholesterol significantly increased at six months.
    • Lecithin cholesterol acyl-transferase activity was significantly higher during pindolol treatment.

    Conclusions:

    • Pindolol appears to have fewer adverse effects on lipid metabolism compared to beta-blockers lacking intrinsic sympathomimetic activity.
    • Pindolol may be a suitable option for hypertensive patients concerned about lipid profile disturbances.
