Abdominal aortic aneurysm: New treatment may reduce size; COVID infection may speed growth

The intravenous delivery of immune-modulating cells may someday slow the expansion of bulges in the aorta, known as abdominal aortic aneurysms. A second study found evidence that a COVID-19 infection may promote the enlargement of these dangerous bulges. These preliminary studies were presented at the American Heart Association’s Vascular Discovery: From Genes to Medicine Scientific Sessions 2023. The meeting, held May 10–13, 2023, in Boston, is a premier global exchange of the latest advances in new and emerging scientific research in arteriosclerosis, thrombosis, vascular biology, peripheral vascular disease, vascular surgery and functional genomics.
