title: [Thrombolysis following myocardial infarct. European Secondary Prevention Study].
abstract: For evaluation of the management of patients with acute myocardial infarction, all cases of ten Zurich hospitals (278, 184 men and 94 women) in the period from 1 January to 31 March 1993 were analyzed retrospectively. 223 patients were released from hospital, 55 died. A follow-up was done 6 months after the patient's discharge by means of a questionnaires to the family doctor (return rate: 65.9%). 48.5% of patients were referred to hospital within the first 6 h. after onset of symptoms, 64% within the first 12 h. 28% (n = 76) of the patients received a thrombolytic therapy, of which 91% (n = 69) got streptokinase and 9% (n = 7) got tissue plasminogen activator. In 81% of the cases the thrombolytic therapy was done within the first hour in hospital, in accumulated 97% of the cases within two hours. In the age group under 65 years (39% of the patients, n = 109), 48 patients received thrombolysis (odds ratio [OR] = 1.0). In the age group between 65 and 74 years (24.5 % of the patients, n = 68), 19 patients received thrombolysis (OR: 0.49; 95% CI: 0.42-0.99; p < 0.05), and in the age group over 74 years (36.5% of the patients, n = 101), 9 patients were received thrombolysis (OR: 0.12; 95% CI: 0.05-0.28; p < 0.0001). 31% of the patients (n = 46) received a coronary angiography, 15% (n = 22) had coronary angioplasty, and 11% (n = 1) received coronary bypass surgery. There is evidence that there should be more importance attached to early hospitalization, if acute myocardial infarction is suspected. Thereby age alone should be considered as a contraindication for thrombolytic therapy. The issue of assumed underuse of thrombolytic therapy should be investigated all over Switzerland.
