- Twenty-nine patients were randomly allocated to two groups before undergoing aorto-coronary bypass surgery. In one group the beta-blocking medication was withdrawn three days preoperatively, and in the other group it was maintained. The patients in the latter group were additionally given 100 mg metoprolol per os two hours before surgery. The degree of myocardial injury, as judged from cumulated activity of S-CK B, was less when the beta-blockade was maintained.

- In 80 patients who underwent heart surgery the incidence of electrocardiographic (ECG) changes after the operation was analysed. A precordial grid containing 24 leads and leads II, III and aVF was used. Electrocardiographic measurements were taken the day before the operation and again 5 days after the operation. New Q-waves were observed in 2 patients (2.5%) in the 24 precordial leads, in 2 patients in leads II, III and aVF, and in one patient in both precordial leads and leads II, III and aVF. New T-wave inversions were observed in 20 patients (25%) in the 24 precordial leads, in 5 patients (6%) in leads II, III and aVF, and in 3 patients in both precordial leads and leads II, III and aVF. A similar serum enzyme activity was observed both in patients developing Q-waves as well as T-wave inversions compared with cases in whom ECG changes did not appear.
