ST deviation pattern in acute myocardial infarction is not related to lesion location.
BACKGROUND
In ST-elevation MI (STEMI) the culprit artery is usually occluded, whereas non-STEMI (NSTEMI) it is usually patent. The location of the ruptured plaque may influence MI type. We examine whether the distance from the coronary ostium to the culprit lesion is different in STEMI as compared to NSTEMI.


METHODS
We selected patients who presented with an acute MI and underwent coronary angiography during hospitalization. The analysis included 754 patients of whom 514 had STEMI and 240 had NSTEMI. The distance from the coronary ostium to the site of thrombosis was measured.


RESULTS
For both STEMI and NSTEMI patients the first 60 mm of the coronary artery contained 75% of the culprit lesions. There were no significant differences in median distances from the vessel ostium to the site of thrombosis as well.


CONCLUSIONS
The distance from coronary ostium to culprit lesion is similar in STEMI and NSTEMI. Culprit lesion location does not appear to influence the development of STEMI as opposed to NSTEMI.
