[Results of PTCA following thrombolysis in acute myocardial infarct].

The mortality in acute transmural myocardial infarction can be reduced by thrombolytic therapy administered within 6 hours after onset of symptoms. In patients with coronary angiography proven stenosis of less than 70% conservative therapy is recommended. In patients with one vessel disease PTCA in patients with suitable lesions should be used. Further studies have to elucidate, if the angioplasty has to be performed in the acute stage or on an elective basis. PTCA is recommended in patients with occluded coronary vessels and in patients with high grade stenosis and limited coronary blood flow. In patients with multi vessel disease aortocoronary bypass surgery is recommended to reduce high mortality. Long-term results demonstrate, that patients in whom PTCA or coronary bypass surgery was performed demonstrated the highest survival rate.
