Heart signals brain to boost sleep for healing after heart attack, study finds
by The Mount Sinai Hospital Microscopy images of monocytes in the brain of a mouse after a heart attack. Schematic of hypothesized mechanism: after a heart attack, monocytes are released from the bone marrow and recruited to the brain where they produce TNF to increase sleep which limits stress signaling to the heart and promotes heart...

Sex-specific heart attack risk factors linked to circulating proteins
by Justin Jackson , Medical Xpress Graphical abstract. Credit: European Heart Journal (2024). DOI: 10.1093/eurheartj/ehae658 Uppsala University and Karolinska Institutet researchers have identified 45 proteins in the blood that are associated with the risk of myocardial infarction (MI), commonly known as a heart attack. Of the 45 protein associations, 13 were specific to women, and one was specific...

MNT Investigates: Do ulcerative colitis treatments reduce the risk of heart attack?
Research has linked ulcerative colitis (UC) to an increased risk of heart disease, including heart attack and stroke. Some UC treatments may help reduce the risk of heart problems, though more research is necessary. UC refers to chronic inflammation in the inner lining of the large intestine. People with UC may also develop inflammation in...
