title: Effects of nifedipine, acebutolol, and their association on exercise tolerance in patients with effort angina.
abstract: The action of nifedipine (N), acebutolol (A), and their association (A+N) was studied in 16 patients suffering from effort angina with documented coronary artery disease. The therapeutic action was valued by bicycle effort stress test after oral administration of medications in comparison with placebo (P), following a double-blind random sequence of treatments. Working capacity significantly increased after A (507 +/- 450 mkp, p less than 0.05), after N (1,140 +/- 767 mkp, p less than 0.001), and after A+N (1,198 +/- 644 mkp, p less than 0.01). The increments of work after P administration were not significant. Moreover, fatigue instead of angina appeared as a stopping criterion in 8 patients after A+N, and in only 1 patient after P, A, and N.
