Relationship between electrocardiographically estimated infarct size and clinical findings in anterior myocardial infarction
[external].

Abstract [en]

In 292 patients with anterior myocardial infarction (MI) and no previous MI the electrocardiographically estimated infarct size was correlated with clinical findings during hospitalization and 3-month follow-up. Patients with ECG-defined transmural MI had a higher incidence of different types of complications, such as congestive heart failure (CHF), hypotension, pericarditis, and a longer duration of hospitalization than patients with nontransmural MI. In a subgroup including 182 patients of the total series, a precordial map containing 24 electrodes was used. The sum of R waves (sigma R), the sum of Q waves (sigma Q), the number of Q waves, and sigma R - sigma Q were calculated 4 days after arrival in hospital to estimate the size of infarction. There was generally a correlation between these ECG variables and different clinical findings, such as incidence of CHF, hypotension, pericarditis, and the duration of hospitalization. It is concluded that the ECG determined infarct size in anterior MI in a majority of patients correlates with the incidence of different types of complications in acute myocardial infarction. In the individual patient, however, the risk of developing complications cannot be predicted by ECG changes.
