The latest analysis from The North American COVID-19 STEMI (NACMI) was presented today as late-breaking clinical research at the Society for Cardiovascular Angiography & Interventions (SCAI) 2023 Scientific Sessions. The findings show patients with an ST-elevated myocardial infarction, or STEMI, and COVID-19 had a significant amount of clotting in their arteries both before and after intervention. Importantly, clots were seen in multiple arteries in close to 30% of patients, a phenomenon observed in less than 5% of patients with heart attacks who do not have COVID-19.
