[Several factors influencing the male sexual function in patients with atherosclerotic disease]
Insights
Impotence is common in patients with arteriosclerosis obliterans (ASO) and abdominal aortic aneurysm (AAA). Penile systolic pressure index (PSPI) is a better predictor of sexual function in ASO patients than ankle systolic pressure index (ASPI).
Area of Science:
- Vascular Surgery
- Andrology
- Cardiovascular Disease
Context:
- Arteriosclerosis obliterans (ASO) and abdominal aortic aneurysm (AAA) are significant vascular conditions.
- Male sexual dysfunction is a common comorbidity in patients with these diseases.
- Understanding the relationship between vascular disease severity and erectile dysfunction is crucial for patient management.
Purpose:
- To investigate the prevalence of male sexual dysfunction in patients with ASO and AAA.
- To analyze the correlation between hemodynamic parameters (PSPI, ASPI) and sexual function.
- To determine the predictive value of PSPI and ASPI for impotence in these patient cohorts.
Summary:
- A study of 58 ASO, 27 AAA, and 4 combined disease patients revealed high impotence rates (66% in ASO, 52% in AAA).
- In ASO patients, a higher penile systolic pressure index (PSPI) correlated significantly with preserved sexual function (r = 0.49, p < 0.01).
- PSPI (cutoff 0.70) demonstrated 84% accuracy in classifying impotence in ASO patients, outperforming ASPI (cutoff 0.45, 69% accuracy).
Impact:
- This research highlights the significant impact of vascular disease on male sexual health.
- PSPI emerges as a valuable, non-invasive tool for assessing erectile dysfunction risk in ASO patients.
- Findings can guide clinical evaluation and treatment strategies for sexual dysfunction in patients with peripheral arterial disease and aortic aneurysms.
Abstract:
Patients with arteriosclerosis obliterans (ASO, n = 58), abdominal aortic aneurysm (AAA, n = 27) and the combined disease (n = 4) were the subjects of this study. All patients were evaluated by retrograde aortography and questioned personally as to their present male sexual function. The penile and ankle systolic pressure index (PSPI and ASPI) of patients with ASO were measured using a Doppler device, but in the patients with AAA, only the PSPI was taken. Several factors relating to male sexual function, such as, age, PSPI, ASPI, sites of the arterial occlusion or dilatation, classification of the ischemic symptoms according to Fontaine's category, numbers of pulsations of the femoral artery, were statistically analysed. All of the patients with both diseases, 66 percent of those with ASO and 52 percent of those with AAA were impotent. In the patients with AAA, the PSPI of the potent group was not significantly higher than that of the impotent group; however, in patients with ASO, the PSPI of the former group was significantly higher than that of the latter group. In the patients with ASO, a significant correlation between the PSPI and the ASPI (r = 0.49, p less than 0.01) was found. When a PSPI value (PSPI = 0,70) was chosen as a demarcation between the impotent group and the potent group, 84 percent of the patients with ASO were correctly classified. However, when the ASPI (ASPI = 0.45) was used, only 69 percent were properly classified.(ABSTRACT TRUNCATED AT 250 WORDS)
