Enhanced External Counterpulsation in Patients with Coronary Artery Disease-Associated Erectile Dysfunction. Part II: Impact of Disease Duration and Treatment Courses

Enhanced external counterpulsation in rehabilitation of erectile dysfunction: a narrative literature review

Background

Enhanced external counterpulsation (EECP) is a noninvasive treatment option widely applied in patients with erectile dysfunction (ED). The aim of this study is to review the efficacy of EECP in patients suffering from ED.

Methods

PubMed, MEDLINE, Google Scholar, Tripdatabase, Scopus, and Cochrane library databases were searched for articles with the following search terms: enhanced external counterpulsation and erectile dysfunction. No restrictions with respect to study setting, date of publication, and language were imposed.

Results

From an initial set of 208 records, 4 studies were selected after a final review. A total of 177 patients with a mean age of 59.98 years were included in these studies, with 20–35 hours per week of EECP treatment. Three studies used the International Index of Erectile Function questionnaire and one applied a four-item questionnaire and a peak systolic flow measurement. All of these parameters were significantly improved after the EECP treatment.

Conclusion

To the best of our knowledge, this is the first study reviewing the clinical effectiveness of EECP in patients with ED. According to the articles reviewed in this study, an improvement in erectile function after EECP treatment courses has been observed in patients with and without coronary artery disease without any significant adverse effects.

Efficacy of Enhanced External Counterpulsation in Patients With Chronic Refractory Angina on Canadian Cardiovascular Society (CCS) Angina Class: An Updated Meta-Analysis

A growing number of patients with chronic artery disease suffer from angina, despite the optimal medical management (ie, β-blockers, calcium channel blockers, and long-acting nitrates) and revascularization. Currently, enhanced external counterpulsation (EECP) therapy has been verified as a noninvasive, safe therapy for refractory angina. The study was designed to evaluate the efficacy of EECP in patients with chronic refractory angina according to Canadian Cardiovascular Society (CCS) angina class.We identified systematic literature through MEDLINE, EMBASE, the Cochrane Clinical Trials Register Database, and the ClinicalTrials. gov Website from 1990 to 2015. Studies were considered eligible if they were prospective and reported data on CCS class before and after EECP treatment. Meta-analysis was performed to assess the efficacy of EECP therapy by at least 1 CCS angina class improvement, and proportion along with the 95% confidence interval (CI) was calculated. Statistical heterogeneity was calculated by I statistic and the Q statistic. Sensitivity analysis was addressed to test the influence of trials on the overall pooled results. Subgroup analysis was applied to explore potential reasons for heterogeneity.Eighteen studies were enrolled in our meta-analysis. Pooled analysis showed 85% of patients underwent EECP had a reduction by at least one CCS class (95%CI 0.81-0.88, I = 58.5%, P < 0.001). The proportion of patients enrolled at primarily different studies with chronic heart failure (CHF) improved by at least 1 CCS class was about 84% after EECP (95%CI 0.81-0.88, I = 32.7%, P = 0.1668). After 3 large studies were excluded, the pooled proportion was 82% (95%CI 0.79-0.86, I = 18%, P = 0.2528). Funnel plot indicated that some asymmetry while the Begg and Egger bias statistic showed no publication bias (P = 0.1495 and 0.2859, respectively).Our study confirmed that EECP provided an effective treatment for patients who were unresponsive to medical management and/or invasive therapy. However, the long-term benefits of EECP therapy needed further studies to evaluate in the management of chronic refractory angina.

Erectile dysfunction in Arab countries. Part II: Diagnosis and treatment

Objective

To review local published data on the diagnosis and treatment of erectile dysfunction (ED) in Arab countries.

Methods

MEDLINE was searched for English-language articles published from 2000 to 2011, using the search terms ‘Arab countries’, ‘sexual dysfunction’, ‘diagnosis’ and ‘treatment’.

Results

In all, 86 articles were found to be relevant to this review; only a few had a high level of evidence and the remaining studies used an uncontrolled design. Several local studies were consistent with previous reports showing that a customised diagnostic pathway, with full consideration of the patient’s goals, is adopted by most clinicians to treat ED. For an effective treatment, the evaluation methods should answer important questions about the aetiology and severity of ED, as well as the patient’s and partner’s goals and expectations. As ED is known to be associated with many common medical comorbidities and medications, careful questioning can yield information about peripheral vascular disease, coronary artery disease, diabetes, hypertension, dyslipidaemia, and tobacco and alcohol use. The presence of psychological, neurological or chronic debilitating diseases can direct further evaluation.

Conclusion

The methods used for the diagnosis and treatment of ED need more investigation, especially in Arab countries. Only a few studies addressed the results of different methods of investigating and treating ED among Arab men.

Gender impact on the correlation between sexuality and marital relation quality in patients with coronary artery disease

INTRODUCTION

Although the negative impact of coronary artery disease (CAD) on sexual and marital relation of the patients is known, data are lacking regarding possible gender difference.

AIM

We designed a study on patients with CAD to investigate sexual relation and marital adjustment and their association with regard to gender differences.

MAIN OUTCOME MEASURES

Questionnaires including the Dyadic Adjustment Scale for evaluating the couple's agreement on decisions and appropriate behavior, marital satisfaction, and marital cohesion, and the Relation and Sexuality Scale (RSS) for sexual function, frequency, and fear.

METHODS

We surveyed 650 patients with documented CAD without any other major comorbidities.

RESULTS

The patients were 464 men (73.1%) and 171 women (26.9%) with CAD. The mean age of the men and the women were 57.1 +/- 11.6 years and 56.3 +/- 9.7 years, respectively. The women had a significantly poorer dyadic adjustment and sexual relation than men, except for sexual fear, which was more prominent in men with CAD and their spouses. The sexual frequency and the total RSS scores correlated with all aspects of the patients' marital relation in both genders. However, only men suffered from a poorer dyadic satisfaction, dyadic consensus, affectional expression, and overall marital adjustment if they were more afraid of sexual relation. In women, but not men, sexual function was significantly associated with their dyadic satisfaction and their overall marital relation.

CONCLUSIONS

Poorer sexual relation and marital adjustment was detected in our women with CAD. To manage all the problems of the patients that may impact their cardiac status, we should consider factors such as fear of sexual activity in men sexual dysfunction in women, and their correlation with marital adjustment.
