This study looks at, a, um, rising star among cardiovascular risk factors: erectile dysfunction. ED and cardiovascular disease share many common risk factors (diabetes, smoking, obesity, etc), and prior studies have shown ED patients to have increased subclinical vascular disease such as increased coronary calcium scores, increased carotid plaque scores, etc.
Utilizing the MESA study, the authors followed ~1750 participants for 3.8 years on average, evaluating for cardiovascular disease (AMI, stroke, cardiac arrest, death) and coronary heart disease. Patients self-reported ED via the Massachusetts Male Aging Study. Obviously this study is plagued by self-assessments which may or may not accurate, a composite endpoint, and is based on prior studies demonstrating the worsening surrogate markers; the authors do not tease out individual AMI, stroke or death risk from the composite endpoints either.
Ultimately, ED patients had more adverse cardiovascular events (6.3% versus 2.6%), resulting in an unadjusted hazard ratio of 2.6 and the risk persisted even after adjustment for traditional CVD risk factors, depression, and beta-blocker use. Think of ED as an early warning sign of endothelial dysfunction, inflammation, and possibility, atherosclerosis. ED is already in some UK risk stratification scores, will it make it to the US?
