[Effectiveness of obsidan in patients with ischemic heart disease and its effect on myocardial perfusion]

Obsidan effectiveness was examined in 42 coronary patients. Good clinical effect was achieved in 81% of patients with angina of effort and 64% of patients with angina of effort and angina at rest. Exercise tolerance increased in half of the patients. Radionuclide scintigraphy with 201Tl showed a reduction of exercise-induced transitory myocardial ischemia zones, a finding indicative of obsidan favourable effect on coronary microcirculation reserve.
