A long-term study on the effect of pindolol on serum lipoproteins: a preliminary report.

1. Preliminary results are reported from a long-term study aimed at recording the concentrations of serum lipids and lipoproteins at 6, 12 and 24 months of treatment with pindolol in young/middle-aged males with moderate hypertension. 2. Seventy-three patients have been recruited, of whom 47 have completed 6 months treatment. After 6 months treatment 35/47 patients had attained the target blood pressure of less than or equal to 95 mm Hg and analysis of plasma lipid and lipoprotein concentrations revealed a tendency for an increase of serum triglycerides and a lowering of low density lipoprotein cholesterol.
