Comparison of bopindolol and atenolol in chronic stable angina pectoris.

The efficacy of bopindolol and atenolol in the treatment of patients with chronic stable angina pectoris have been compared in a double blind, randomized study. Both bopindolol 1 mg and atenolol 100 mg for 6 weeks increased mean exercise time (25% and 22%, respectively, compared to placebo), time to angina (27% and 25%), and time to 1 mm of ST-segment depression (32% and 20%). Both drugs reduced ST-segment depression similarly at maximal and submaximal work levels. There was no significant difference in their antianginal efficacy.
