Article presents actual comparison of therapeutic methods for patients with chronic coronary artery disease and their influence on morbidity and mortality. It calls attention to the insufficiently presented fact, that invasive methods, like percutaneous and surgical revascularization, despite great expectations, have not proved to lower morbidity and mortality in large randomized studies. In contrary several groups of drugs proved their efficiency many times. Paradoxically, the cheapest approach, life style intervention, seems to be the most efficient method for prognosis improvement of patients with chronic coronary artery disease.
