Coronary collateral circulation status is correlated with the initial electrocardiographic pattern in ST-elevation myocardial infarction

The status of coronary collateral circulation (CC) in the first hours of ST-elevation myocardial infarction (STEMI) may influence outcome. Early recognition of the CC status may have therapeutic and prognostic implications. Our purpose was to correlate the electrocardiogram (ECG) pattern and CC in STEMI.
