IIn some patients, infection with the pandemic virus SARS-CoV-2 can trigger a dangerous immune response in hardened fatty deposits (plaques) that line the heart’s largest blood vessels, new research suggests. research has shown. The findings are based on the body’s immune system, which evolved to destroy invading microorganisms, but can also cause disease if triggered in the wrong circumstances. Doing so triggers a series of reactions called inflammation, including swelling, which causes immune cells and signaling proteins to return to the site of infection. Inappropriate inflammation can cause immediate and long-term heart problems, including the breakdown of artery-clogging plaque, and…
AnimalsNeonatal CM isolation and culture in vitroNeonatal hearts were dissected from P0–1 C57bl/6 pups, washed with ice-cold PBS and dissociated using standard procedures. Neonatal CMs were seeded in culture plates precoated with fibronectin (0.8–1 million per 3.5-cm dish or 0.25 to 0.4 million per well of 2-well chamber slides) and cultured in primary neonatal CM culture medium (80% DMEM with 4.5 g l−1 glucose, 20% Medium 199, 5% FCS and 100 U ml−1 penicillin and streptomycin). After overnight culture, chemicals were added to the medium and cells were further cultured for 72–96 h before collection. Concentrations of chemical were as follows: etomoxir 100 μM (Cayman,…

People who have one or more heart attacks during their lifetime may experience faster long-term cognitive decline, according to an NIA-funded study.. Heart attacks were not associated with cognitive decline immediately after the event.

A research team led by Johns Hopkins University set out to discover whether experiencing a myocardial infarction or heart attack is associated with subsequent changes in cognitive function. The researchers analyzed six NIH-funded longitudinal cohort studies of cardiovascular health conducted from…
