    Abstract:
    The aim of this study was to evaluate the outcome of primary percutaneous transluminal coronary angiography (PTCA) in the treatment of acute myocardial infarction (AMI) The study included patients with electrocardiographic signs of transmural AMI, symptom duration of less than 12 h, and with no contraindications to thrombolytic therapy. Patients who had undergone primary PTCA were matched consecutively, for age, gender, infarct localization and duration of symptoms, to patients who had received thrombolytic therapy (82 patients to each group). Patients who were admitted to hospital during daytime had a primary PTCA, whereas those admitted outside daytime were given thrombolytic therapy. In the primary PTCA group, 9 patients had a combined endpoint compared with 22 patients in the thrombolysis group (p < 0.02 ). In-hospital mortality was 3.7% in the PTCA group and 4.9% in the thrombolysis group (ns). At six months, a combined endpoint occurred in 23 patients in the primary PTCA group and in 50 patients in the thrombolysis group (p < 0.00005). Six months' mortality was 4.9% in the PTCA group and 7.3% in the thrombolysis group (ns). Among patients in the PTCA group, left ventricular ejection fraction was significantly higher, stay in hospital was shorter and there were significantly fewer incidences of heart failure and severe arrhythmias than among patients in the thrombolysis group. The results of primary PTCA implemented in our departments are comparable with those reported in randomized trials from experienced centres. Our study indicates that patients treated with primary PTCA have fewer complications, a better left ventricular systolic function and a shorter hospital stay compared with patients treated with thrombolysis.
