Application of Sildenafil in patients with documented coronary vasospasm in order to explore the pathophysiology of coronary vasospasm and the therapeutic effects of Sildenafil in patients suffering from coronary spasmCoronary vasospasm is an abrupt severe vasoconstriction of coronary arteries leading to myocardial ischemia and angina pectoris. The reason for the occurrence of coronary spasm and the cellular mechanism causing coronary spasm is still not elucidated. Thus, an appropriate medical therapy has not been established so far. In patients suffering from coronary vasospasm the possible anti-spastic effect of sildenafil is to be analysed with this study.EUCTR2006-003116-22-DEProf. Sechtem, Department of Cardiology, Robert Bosch Hospital
