- In 709 patients with definite acute myocardial infarction (MI) the appearance of raised serum enzyme activity was related to onset of symptoms. Heat stable lactate dehydrogenase (LD), creatine kinase (CK) and CK B were analysed. A gradual increase in the incidence of raised enzyme activity in the first blood sample was seen for up to 18 hours after the onset of MI for all 3 enzymes. The incidence of raised enzyme activity in the first blood sample was higher for CK and CK B than for heat stable LD up to 24 hours after onset of MI, but thereafter a similar incidence was found. The median time between onset of symptoms and estimated appearance of raised serum enzyme activity was 6.2 hours for heat stable LD versus 4.3 hours for CK and 4.1 hours for CK B. A wide variation was however found. Infarct localization and chronic treatment with betablockade might affect these results. The clinical course including short- and long-term survival was similar in patients with early and later appearance of enzymes.

- In 680 patients with acute myocardial infarction the prognosis during the following 5 years was related to observations made in a standard electrocardiogram (ECG) and 24 precordial chest leads. Patients with a Q-wave infarction (based on a 12-lead standard ECG) had a mortality rate during hospitalization of 10.2% which was much higher than that in patients with a non-Q-wave infarction (1.9%, p less than 0.001). At 5 years' follow-up 33.6% of those with a Q-wave infarction had died versus 28.4% of those with a non-Q-wave infarction (p greater than 0.2). Corresponding mortality rate among patients with no previous infarction (n = 587) was 32.1% and 25.2%, respectively (p = 0.17). In patients with anterior infarction and no previous infarction there was no correlation between Q- and R-wave changes in the 24 chest leads 4 days after admission to hospital and 5-year mortality rate. We thus conclude that patients with a Q-wave infarction had a higher in-hospital mortality compared with non-Q-wave infarction as judged from standard ECG, whereas 5-year mortality was similar. Similarly, there was no correlation between Q- and R-wave changes in an increased number of chest leads and 5-year mortality rate.
