[The effect of verapamil on the course of stenocardia of effort, on the blood serum lipid level and on the basic indices of carbohydrate metabolism during the long-term use of the preparation].

The therapeutical efficiency of verapamil given for 3 months was studied in 36 patients with stable exercise-induced angina by multistep gradually increasing bicycle ergometry exercise test. The effects of the agent on serum lipid levels were evaluated in 30 cases. The therapeutical effect was achieved in 24 patients; verapamil caused a pronounced increase in physical working capacity just during the acute drug test in all cases and showing growing effects within a month of treatment. No increase in therapeutical effects was observed in 12 cases in whom a rise in exercise time was insignificant during the acute drug test. Verapamil produced no noticeable effect on fasting serum glucose and insulin levels after glucose tolerance test in 19 healthy individuals and 11 patients with lower carbohydrate tolerance. Thirteen patients with primary hypercholesterolemia had decreased levels of total cholesterol due to low density lipoprotein cholesterol.
