Why the study?
The association between increased supraventricular ectopic beats and subclinical cerebrovascular disease remains unclear, despite emerging views that ectopy marks atrial cardiomyopathy or atherosclerosis.
Is excessive supraventricular ectopic activity associated with a higher burden of subclinical cerebrovascular disease in middle-aged to older men without stroke or atrial fibrillation?
Population
462 men (mean age, 68.1 years) without apparent stroke or atrial fibrillation
Comparison
Excessive supraventricular ectopic activity (>10 SVEBs/h) vs ≤10 SVEBs/h
Design
Cross-sectional population-based study

ESVEA may support risk stratification for subclinical cerebrovascular disease; leaves open causal links and clinical utility pending longitudinal data.
Is excessive supraventricular ectopic activity associated with a higher burden of subclinical cerebrovascular disease in middle-aged to older men without stroke or atrial fibrillation?
Excessive supraventricular ectopic activity is independently associated with higher burdens of white matter hyperintensity and intracranial atherosclerotic stenosis, suggesting its potential utility in risk-stratifying individuals for subclinical cerebrovascular disease.
