Antibodies against angiotensin II type 1 and endothelin-1 type A receptors are associated with microvascular obstruction after revascularized ST-elevation myocardial infarction.

The article published in the European Heart Journal Open in 2024 explores the association between antibodies against angiotensin II type 1 and endothelin-1 type A receptors with microvascular obstruction after revascularized ST-elevation myocardial infarction. The study conducted at the University of Padua Hospital involved 56 patients who underwent cardiac magnetic resonance imaging. Results indicated a higher prevalence of microvascular obstruction in patients with seropositivity for these antibodies, suggesting a potential cumulative effect on the risk of microvascular damage post-STEMI. Further research is needed to understand the molecular mechanisms underlying this association and develop new therapies for microvascular obstruction. [Extracted from the article]
