TLDR Men with severe androgenetic alopecia, especially on the top of the head, have a higher risk of coronary artery disease.
A study conducted over 6 months investigated the association between androgenetic alopecia (AGA) and coronary artery disease (CAD) in 100 male patients with CAD and age-matched controls without systemic diseases. AGA was present in 78% of the CAD cases compared to 52% of the controls, indicating a statistically significant association between AGA and CAD (P < 0.001). The study found that the severity of AGA, particularly involving the vertex, was more predictive of CAD risk than the mere presence of AGA.
