A new study published in The American Journal of Cardiology revealed acute total occlusion (ATO) in non-ST-segment elevation myocardial infarction (NSTEMI) patients undergoing PCI, which was most common in the left circumflex artery. ATO was associated with a 46% higher risk of major adverse cardiovascular events (MACE) over 3.6 years (aHR 1.46; p=0.002).

In a retrospective analysis of 1,128 NSTEMI patients who underwent coronary angiography this research was set determine the impact of vessel occlusion on clinical outcomes. The patients were divided into a group with total occlusion (TO) and other group with non-total occlusion (Non-TO). The study followed patients for a median of 3.6 years to track the occurrence of MACE, including all-cause death, non-fatal heart attack, non-fatal st
