    Abstract:
    OBJECTIVE: To review the results and complications of thrombolysis in patients with acute myocardial infarction (AMI) and its complications. METHODS: Since june 1989 to august 1994 we studied patients with AMI, who underwent thrombolysis. Clinical characteristics, complications and angiographic results are described. RESULTS: Of the total population 86.3% patients received Streptokinase (SK) and 13.7% recombinant tissue plasminogen activator (rt-PA). In 20 patients the age was under 40 years, 373 between 40-70 years, and 80 patients over 70 years. 84% were men and 16% women. 72% had smoking habit; 21% diabetes mellitus, 43% hypertension, 54% had previous angina and previous AMI in 22%. The location of AMI was anterior in 234 patients and 239 inferior. In 63% enzyme washout was observed, and rapid electrocardiographic evolution in 81%. Postthrombolisis arrhythmias was observed in 64.7%. Major bleeding in 11.8% and central nervous system hemorrhage in 0.4% only with rt-PA. Postinfarction angina in 22%, and re-infarction in 4%. Cardiac rupture in 1.4%, with shock and death. Mitral insufficiency in 2.1% demonstrated by echocardiogram. Coronary angiography was done in 373 patients (80%), of which 50.7% was made in the first 5 days. The culprit artery was anterior descending in 273 patients and right coronary in 95. Left ventricular dysfunction was seen in 23% in patients with anterior AMI, and 5% with inferior AMI. Cardiogenic shock was seen in 7%. Coronary artery bypass grafting was undertaken in 106 patients and coronary angioplasty in 67. The ten days mortality was 8.8%, principally due to cardiogenic shock, ventricular arrhythmias and ventricular rupture. CONCLUSIONS: The usefull permeability in the culprit artery was obtained in 40%, who had coronary angiography done 145 hours posthrombolysis. Mortality was under 10% in this study.
