Distal embolization occurs in approximately 15% of primary angioplasty cases for acute myocardial infarction and is associated with worse reperfusion and poorer clinical outcomes.
Answers are grounded in this paper and cite their sources.
Distal embolization on angiogram identifies higher-risk STEMI; hypothesis-generating for prevention, should not yet change practice.
Distal embolization in patients treated with primary angioplasty is visible on the coronary angiogram in 15.2% of patients. It is related to reduced myocardial reperfusion, more extensive myocardial damage and a poor prognosis. Additional pharmacological interventions and/ or mechanical devices should be studied to prevent and/or treat distal embolization.
