[Effect of peripheral vasodilators on pulmonary respiratory function and the indices of bicycle spiroergometry in heart failure patients]

The effect of corinfar and isosorbide on respiratory function of the lungs and indices of spirobicycle ergometry was studied in 40 patients with heart failure resulting from various heart diseases. The results have shown that despite difference in the mechanism of action, the use of these drugs at the given doses combined with digoxin is accompanied by a distinct and comparable positive influence on external respiratory function and indices of spirobicycle ergometry in patients with heart failure.
