Key result
Total right coronary artery occlusion showed characteristic inferior infarct ECG changes in 44% of patients, and 86% of patients with typical inferior infarct ECGs had severe right coronary disease.
Why the study?
Does electrocardiographic evidence of inferior myocardial infarction accurately predict right coronary artery occlusive disease, and vice versa?
Population

Typical inferior ECG changes were associated with severe RCA disease but absent in most total occlusions; leaves open role in diagnosis pending validation.

Does electrocardiographic evidence of inferior myocardial infarction accurately predict right coronary artery occlusive disease, and vice versa?
Electrocardiographic evidence of an inferior myocardial infarction strongly correlates with severe right coronary artery occlusive disease, though extensive collateral circulation may mask typical ECG changes in patients with total occlusion.
Dwyer et al. (1975) conducted an observational in Inferior myocardial infarction and right coronary artery occlusive disease (n=100). Total occlusion of the right coronary artery or inferior transmural infarction was evaluated on Correlation between electrocardiogram and coronary arteriogram findings. Total right coronary artery occlusion showed characteristic inferior infarct ECG changes in 44% of patients, and 86% of patients with typical inferior infarct ECGs had severe right coronary disease.
