The efficacy of therapy with diltiazem, 360 mg/day, was studied in 11 men with chronic, stable angina pectoris. An initial dose-titration schedule in which diltiazem was increased weekly from placebo to 120, 240 and 360 mg/day (Period I) was followed by a randomized, double-blind, 1-month crossover trial of placebo vs diltiazem at 360 mg/day (Period II). A computer-assisted treadmill exercise test was performed at the end of each dose and each 2-week crossover period. Diltiazem at 360 mg/day, compared with placebo (Period II), significantly improved exercise performance. Exercise duration to onset of chest pain increased 40% from 5.3 +/- 2.1 to 7.4 +/- 2.7 minutes (p less than 0.01). Time to reach 1 mm of ST-segment depression increased 33%, from 5.1 +/- 2.0 to 6.8 +/- 1.8 minutes (p less than 0.01). Total exercise duration increased 16%, from 7.5 +/- 2.0 to 8.7 +/- 2.0 minutes (p less than 0.005). A computer-derived quantitative treadmill exercise score improved 27%, from -13.1 +/- 9.4 to -9.5 +/- 7.6 units (p less than 0.005), and the ST-segment depression at peak exercise improved from -1.9 +/- 1.1 to -1.6 +/- 1.2 mm (p less than 0.05). Progressive improvement in these variables was seen during the single-blind dose-titration period between 120 and 240 mg/day and between 240 and 360 mg/day (Period I). Baseline heart rate (HR) and diastolic blood pressure (BP) in the supine and upright position were significantly lower with diltiazem than with placebo.(ABSTRACT TRUNCATED AT 250 WORDS)
