Although myocarditis and pericarditis were not observed as adverse events in coronavirus
disease 2019 (COVID-19) vaccine trials, there have been numerous reports of suspected …

Background— Increased superoxide production contributes to reduced vascular nitric oxide
(NO) bioactivity and endothelial dysfunction in experimental models of diabetes. We …

Background The medium-term effects of Coronavirus disease (COVID-19) on organ health,
exercise capacity, cognition, quality of life and mental health are poorly understood. Methods …

Superoxide anion plays important roles in vascular disease states. Increased superoxide
production contributes to reduced nitric oxide (NO) bioactivity and endothelial dysfunction in …

Early detection of vascular inflammation would allow deployment of targeted strategies for
the prevention or treatment of multiple disease states. Because vascular inflammation is not …

Background Coronary artery inflammation inhibits adipogenesis in adjacent perivascular fat.
A novel imaging biomarker—the perivascular fat attenuation index (FAI)—captures …

Nitric oxide (NO), produced by endothelial nitric oxide synthase (eNOS), is a key signaling
molecule in vascular homeostasis. Loss of NO bioavailability due to reduced synthesis and …

Human atrial fibrillation (AF) has been associated with increased atrial oxidative stress. In
animal models, inhibition of reactive oxygen species prevents atrial remodeling induced by …

Background— The circulating form of folic acid, 5-methyltetrahydrofolate (5-MTHF), may
have beneficial effects on endothelial function; however, its mechanisms of action remain …

Background: Myocarditis is more common after severe acute respiratory syndrome coronavirus
2 infection than after COVID-19 vaccination, but the risks in younger people and after …
