Abstract/OtherAbstract:
INTRODUCTION: Pulse pressure (PP; i.e., the arithmetic difference between systolic and diastolic blood pressure) has been suggested to be an independent cardiovascular risk (CV) factor in the general population. We previously also reported a negative association between PP and arteriogenic erectile dysfunction (ED). This finding has recently been questioned.
AIM: To verify the association of PP with ED severity and to evaluate its role in predicting forthcoming CV events.
METHODS: This is an observational prospective cohort study evaluating a consecutive series of 1,687 patients attending our Andrological Unit for ED.
MAIN OUTCOME MEASURES: Several hormonal and biochemical parameters were studied, along with SIEDY structured interviews and penile Doppler ultrasound.
RESULTS: Subjects with PP in the lowest quartile (I: 20-45; II: 46-55; III: 56-62; IV: 63-115 mm Hg) had a significant reduction in the risk of severe ED (RR = 0.60[0.47-0.76]; P < 0.0001). When the same analysis was repeated as a function of age quartile (I = 17-44, II = 45-55, III = 56-62, and IV = 63-88 years old), after adjusting for testosterone levels, mean blood pressure, Chronic Disease Score, and body mass index, PP was inversely related to ED only in the youngest age group. During a mean follow up of 4.4 ± 2.6 years, 147 major cardiovascular events (MACE) were observed. In a Cox regression model, after adjusting for possible confounding factors, a lower PP was associated with a lower risk of MACE in the whole sample and in younger subjects, but not in the older ones.
CONCLUSIONS: Checking for blood pressure in ED subjects and calculating PP should become a routine practice in sexual medicine. In younger individuals, low PP reflects not only sexual health (better erection) but also cardiovascular health (less prevalence of MACE).
