Abstract/OtherAbstract:

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. |
