[Efficacy of using vasodilating preparations in latent heart failure in patients with chronic ischemic heart disease].

The tolerance to exercise and parameters of the central hemodynamics were studied in 111 patients with coronary heart disease and latent cardiac failure. It has been ascertained that they have a considerably increased peripheral resistance. The treatment with erinit and nitrong improves the propulsive function of the heart and diminishes significantly the peripheral resistance which results in an increased tolerance to physical load. The latter depends on the degree of the peripheral resistance decrease due to erinit and nitrong. Vasodilating agents may be useful in preventing the progression of heart failure in patients with coronary heart disease.
