Why the study?
Does a left dominant coronary artery system affect short- and long-term outcomes in patients after STEMI?
Does a left dominant coronary artery system affect short- and long-term outcomes in patients after STEMI?
Left coronary dominance is a risk factor for early mortality and reinfarction following STEMI, but does not affect long-term outcomes in early survivors.
Left dominance signals higher early post-STEMI risk; hypothesis-generating and should not yet change practice.
A left dominant coronary artery system is associated with a significantly increased risk of 30-day mortality and early reinfarction after STEMI. After surviving the first 30-days post-STEMI, coronary vessel dominance had no influence on long-term outcome.
