Percutaneous transluminal coronary angioplasty with and without thrombolytic therapy for treatment of acute myocardial infarction

摘要: Successful percutaneous transluminal coronary angioplasty (PTCA) was performed during evolving acute myocardial infarction (AMI) in 41 patients. Catheterization within 1 hour of presentation, from to 12 hours (mean 3.3) following symptom onset. In 17 29 patients with a totally occluded artery, successful thrombolytic therapy followed by PTCA residual high-grade atheromatous stenosis. without prior employed 11 subtotal stenoses producing syndromes and two having critical not immediately responsible for AMI. Three experienced early in-hospital reocclusion reinfarction. One death occurred patient presenting cardiogenic shock. All remaining had prompt pain relief, subsequent stable clinical courses, no or late angiographic evidence reocclusion. Dramatic improvement regional global left ventricular function evident 22 27 undergoing angiography. At follow-up, 94% remained free angina although three required repeat dilatation recurrent stenoses. We concluded that may be selected AMI reduce the likelihood therapy.
