title: [High-dose single administration of isosorbide dinitrate: effect on diurnal distribution of transitory myocardial ischemia in patients with stable angina pectoris].
abstract: We studied the effect of a monotherapy of isosorbiddinitrate on symptomatic and asymptomatic ischemic episodes in 15 ambulatory patients with chronic stable angina pectoris, positive exercise test, and coronary stenosis greater than 70%. Transient ST-segment depression (greater than 0.1 mV for at least 1 min) was documented by 48-h Holter monitoring during a control period without anti-ischemic therapy and at the end of 14 days of treatment with 120 mg o.d. isosorbiddinitrate slow-release. In the control period, 68 asymptomatic and 28 symptomatic ischemic episodes were detected; most of the episodes occurred in the morning between 6.00h and 12.00h (41 episodes) and in the afternoon between 12.00h and 18.00h (36 episodes). Under anti-ischemic therapy the number of episodes and the total duration of ischemia was reduced by 46% and 53%, respectively (p less than 0.01). The anti-ischemic effect was most evident during the morning and the afternoon; the ischemic episodes during the evening and the night were not significantly diminished. It is concluded that in patients with stable angina pectoris a single high-dose of isosorbiddinitrate significantly reduces the number and duration of transient ischemic episodes during daily life.
