Exploring the Connection: Moyamoya Disease and Its Implications for Cardiovascular Health.

Moyamoya disease (MMD) is a vascular disorder characterized by steno-occlusive alterations in cerebral arteries, often resulting in ischemic or hemorrhagic events predominantly affecting the female population and more common in Asian populations. Despite its predominantly neurological manifestations, recent research suggests a potential association between MMD and cardiovascular diseases (CVDs). MMD involves various genetic and environmental factors, with mutations in the RNF213 gene being strongly implicated in disease susceptibility, with histopathological findings revealing intimal lesions and smooth muscle proliferation, contributing to vascular occlusion as well as dysregulation of circulating endothelial and smooth muscle progenitor cells further complicating MMD's pathogenesis. However, the exact nature of the relationship between MMD and CVD remains incompletely understood, and emerging evidence suggests a potential interplay between these pathologies. In this study, we discuss the potential link between MMD and CVD, exploring genetic factors, pathophysiological mechanisms, and studies highlighting cardiac manifestations in MMD patients.
