Key result
Normal or fairly normal ECGs 1-2 years after a first myocardial infarction were associated with a lower 5-year incidence of sudden death and total CHD death compared to abnormal ECG patterns.
Why the study?
Do abnormal ECG patterns 1-2 years after a first myocardial infarction predict the 5-year incidence of reinfarction, angina, sudden death, or total CHD death in male survivors?

Do abnormal ECG patterns 1-2 years after a first myocardial infarction predict the 5-year incidence of reinfarction, angina, sudden death, or total CHD death in male survivors?
A normal or fairly normal ECG 1-2 years after a first myocardial infarction is associated with a lower 5-year risk of sudden death and total CHD death, though it does not predict reinfarction or angina.
Leren et al. (1970) conducted a cohort in Myocardial infarction (n=412). Abnormal ECG patterns (major Q-changes, Q- and T-changes, or mixed changes) vs. Normal or fairly normal ECGs was evaluated on 5-year incidence of myocardial reinfarction, acquired angina pectoris, sudden death, and total CHD death. Normal or fairly normal ECGs 1-2 years after a first myocardial infarction were associated with a lower 5-year incidence of sudden death and total CHD death compared to abnormal ECG patterns.
