[Influence of combination therapy (isosorbide dinitrate and molsidomine) on the incidence of angina pectoris in patients with coronary heart disease].

UNLABELLED

Angina pectoris in patients with severe 3-vessel-disease refractory to treatment is a challenge for the treating physician. We have therefore tested the treatment efficacy of isosorbide dinitrate combined with molidomine on the frequency of angina pectoris in patients with symptoms refractory to treatment.

PATIENTS AND METHODS

15 patients with severe coronary heart disease were included in the study. The protocol included a 2-weeks stabilisation phase, followed by a 4-weeks treatment phase with 100 mg isosorbide dinitrate in the morning as well as 8 mg slow-release molsidomine at 6 p.m.

RESULTS

Initially all of the 15 patients reported about daily angina pectoris attacks. After 4 weeks of treatment 4 out of 15 patients became free of symptoms. From the other 11 patients 6 reported an improvement, 5 an unchanged frequency of attacks.

DISCUSSION

Combination treatment with isosorbide dinitrate with molsidomine in a slow-release form (in the nitrate free interval) showed a distinct improvement in patients with angina pectoris refractory to treatment with reduction of complaints. The effect of the combination is possibly based on a prolonged vasodilatation of the stenosed vessels and a prolonged reduction of filling pressure (reduction of preload).
