Arterial Structure and Function Following Viral Myocarditis

Abstract

Acute viral myocarditis is an uncommon inflammatory disease of the myocardium. Little is known about the long-term cardiovascular risk for individuals who have recovered from the acute illness. We compared intermediate vascular phenotypes relating to arterial structure (aortic and carotid intima-media thickness) and function (pulse wave velocity, carotid arterial distensibility and compliance) in 15 participants, a median of 9.1 years after an episode of acute viral myocarditis, and 45 control participants. Following adjustment for age, sex and triglycerides, there were no differences in mean and maximum carotid and aortic intima-media thickness, pulse wave velocity, carotid artery distensibility and compliance between viral myocarditis participants and controls. In conclusion, we found no evidence of changes in intermediate vascular phenotypes indicative of increased cardiovascular risk in individuals who had fully recovered from viral myocarditis.
