Objective: Many erectile dysfunction (ED) cases are attributed to vascular endothelial dysfunction and impaired blood flow due to arteriosclerotic changes. In this study, we examined the association among the erection hardness score (EHS), pulse wave velocity (PWV), and the presence of carotid artery plaques. Subjects and Methods: The study enrolled 67 patients who visited our hospital with the chief complaint of ED. Based on the history at the first visit, 28 of the 67 patients were categorized into the EHS 3–4 group and the remaining 39 into the EHS 0–2 group. The two groups were retrospectively analyzed. Results: The PWV points were significantly higher in the EHS 0–2 group than in the EHS 3–4 group (P = 0.047). In consideration for error in age, the modified points (PWV at the first visit – reference PWV by age) were significantly higher in the EHS 0–2 group than in the EHS 3–4 group (P = 0.026). This group also showed a higher detection rate of plaques by carotid ultrasound (66.7%). Conclusion: This study showed that patients with lower points of EHS had higher PWV and were more likely to have carotid artery plaques. While ED has occasionally been considered as an early risk marker for the onset of cardiovascular events; this study suggests that the hardness of the penis can be an easier-to-measure and more sensitive index.
