Effects of atrial ischemia on left atrial remodeling in patients with st-segment elevation myocardial infarction

HIGHLIGHTS

SUMMARY

    Particularly, atrial ischemia resulting from coronary flow interruption in a coronary atrial branch (CAB) has been linked to anatomic and functional LA remodeling, with extensive fibrosis present from early phases after acute myocardial infarction. The anatomic variability of CABs in humans5,6 may hamper the evaluation of the impact of atrial ischemia on LA remodeling, as this may vary on the basis of the amount of jeopardized LA myocardium. Coronary flow impairment in the dominant CAB, defined as the largest CAB on coronary angiography, may affect large areas of LA myocardium, with important clinical . . .
