Effects of Sexual Rehabilitation on Sexual Dysfunction in Patients with Cardiovascular Disease: A Systematic Review and Meta-Analysis

Scoping review exploring advancements in topical agent therapies for erectile dysfunction

INTRODUCTION

Erectile dysfunction (ED) is a common issue that affects older men and is often associated with various health conditions. Phosphodiesterase 5 inhibitors are commonly used to treat ED; however, their effectiveness may be limited, or the medication may be contraindicated. Therefore, topical gels are being developed as an alternative option for the pharmacologic treatment of ED.

OBJECTIVES

This review aimed to provide an overview of the efficacy and safety of topical agents for the treatment of ED.

METHODS

The PubMed, Cochrane, Embase, and Web of Science databases were searched. Articles were included that investigated ED and topical agents operating through the skin of the penis, evaluated the effectiveness of the treatment, and involved patients randomized into groups.

RESULTS

Topical alprostadil, glyceryl trinitrate (MED2005), and an over-the-counter formulation (MED3000) were used as alternative treatments for ED in 7 articles, which included 3475 patients. Topical alprostadil induced an erection in 67% to 75% of patients. Adequate erections for vaginal penetration were reported in 38.7% of the alprostadil-treated patients vs 6.9% of the placebo-treated patients. Topical alprostadil significantly and dose dependently improved the total score change on the International Index of Erectile Function as compared with the placebo. MED2005 exhibited a rapid onset of action, with nearly 70% effectiveness within 10 minutes. MED3000 met the minimal clinically important difference threshold of a 4-point increase on the erectile function domain of the International Index of Erectile Function, with an improvement of 5.73 points in 24 weeks. Topical therapy for ED also had acceptable safety profiles.

CONCLUSION

Topical agents via various mechanisms are effective and well-tolerated treatments for ED. A fast-acting drug that significantly reduces side effects as compared with other options has been discovered. However, its efficacy relative to current first-line therapies remains unclear. Topical agents present a viable therapeutic alternative for individuals who are unable or unwilling to take oral phosphodiesterase 5 inhibitors.

Impact of cardiac rehabilitation on erectile dysfunction in cardiovascular patients: a systematic review and meta-analysis

Background

Cardiovascular diseases (CVDs) and erectile dysfunction (ED) frequently co-occur, significantly affecting the quality of life of individuals.

Aim

To assess the impact of cardiac rehabilitation (CR) on ED in patients with CVD through a systematic review and meta-analysis.

Methods

This study analyzed randomized controlled trials and other studies comparing CR with usual care for adult males (≥18 years) with any cardiac disease. Literature searches were extensive, and the risk of bias was evaluated by the Cochrane Collaboration tool. Data from 6 studies involving 668 participants were included in the meta-analysis.

Outcomes

The primary outcome was the improvement in ED, as measured with the International Index of Erectile Function.

Results

A statistically significant improvement in erectile function was observed across 6 studies, with a Morris dppc2 effect size of 0.38 (95% CI, 0.17-0.59). Despite initial high heterogeneity (I 2 = 95.7%), identification and correction for selective outcome reporting bias mitigated this issue.

Clinical Translation

CR has a modest but statistically significant impact on improving ED in patients with CVD, indicating its potential positive contribution to the quality of life of this group.

Strengths and Limitations

The study's strengths include a comprehensive literature search and a rigorous methodological approach. Limitations involve high heterogeneity among studies and a low level of evidence due to small sample sizes and study quality; however, the source of heterogeneity was identified and mitigated following risk-of-bias assessment.

Conclusion

The results suggest that CR has a statistically significant but modest impact on improving ED in patients with CVD. Clinicians should consider the integration of CR into the clinical management of these individuals. This study underscores the potential for CR to contribute positively to the quality of life for patients with CVD by addressing associated ED (PROSPERO: CRD42022374625).

Global prevalence of sexual dysfunction in cardiovascular patients: a systematic review and meta-analysis

BACKGROUND

Sexual dysfunction poses a significant challenge for patients with cardiac conditions. Concerning the prevalence of sexual disorders in cardiovascular patients, several seminal studies conducted in various regions of the world have provided diverse facts and figures pertaining to sexual dysfunction among cardiovascular patients. Therefore, the present study aimed to analyze, summarize, and integrate the findings of seminal studies on the effect of underlying factors and estimate the global rate of sexual disorders in cardiovascular patients.

METHODS

The present systematic review and meta-analysis included studies conducted in 2003-2023. To find the relevant published academic papers, SID, MagIran, PubMed, Scopus, Web of Science (WOS), and Google Scholar databases were searched for keywords using MeSH/Emtree until January 14, 2023. The GRADEpro software was used to evaluate the quality of evidence. The heterogeneity of studies was checked using the I2 index.

RESULTS

An initial number of 2122 studies were found in the first search. Following a precise screening process based on predefined inclusion criteria, a total of 17 studies were deemed suitable for inclusion in the meta-analysis. The global prevalence of sexual disorders in cardiovascular patients was estimated at 62.6% (95% CI: 49.8-73.8%). As the results of the meta-regression showed that as the sample size increased, there was a significant decrease in the overall prevalence of sexual disorders among cardiovascular patients. Additionally, as the study years progressed, both age and JBI score exhibited an upward trend.

CONCLUSION

The present findings showed a high prevalence of sexual disorders among cardiovascular patients. Therefore, it is recommended that experts and health policymakers enhance their focus on effectively preventing and controlling these disorders. Besides the evidence achieved very low certainty, it is important for the treatment team to prioritize the sexual relations of cardiovascular patients and focus on improving their sexual function. This should be seen as an essential aspect of their overall recovery process.

Association between cardiovascular disease and risk of female sexual dysfunction: a systematic review and meta-analysis

AIMS

Female sexual dysfunction (FSD) is a considerably underestimated condition. It has been repeatedly reported that patients with cardiovascular diseases (CVD) may suffer from an increased risk of FSD. However, there is still a lack of comprehensive and systematic evaluation of various CVD and FSD. We aimed to elucidate the association between CVD and FSD through a comprehensive literature review and meta-analysis.

METHODS AND RESULTS

The PubMed, Scopus, Embase, and Cochrane Library databases were systematically searched from inception to 28 February 2023. We identified all relevant studies reporting the risk of FSD in subjects with or without CVD. The associations between CVD and the risk of FSD were assessed by calculating pooled odds ratios (ORs) (cross-sectional studies) and risk ratios (RRs) (longitudinal studies) with 95% CIs. We employed random-effects models to account for potential heterogeneity, and the quality of the included studies was assessed using the Newcastle-Ottawa Scale. Fifty-four articles with 148 946 individuals were included in our meta-analysis. Compared with control subjects, subjects with CVD had a 1.51-fold increased risk of FSD (OR 1.51 95% CI, 1.34-1.69, P < 0.001, heterogeneity I2 = 91.4%, P < 0.001). Subgroup analyses indicated that the association between CVD and FSD remained significant in longitudinal studies (RR 1.50 95% CI, 1.21-1.86, P < 0.001, heterogeneity I2 = 86.7%, P < 0.001). Particularly, hypertension (OR 1.41 95% CI, 1.23-1.62, P < 0.001, heterogeneity I2 = 82.7%, P < 0.001), stroke (OR 1.81 95% CI, 1.54-2.12, P < 0.001, heterogeneity I2 = 0%, P < 0.423), and myocardial infarction (OR 2.07 95% CI, 1.60-2.67, P < 0.001 heterogeneity I2 = 82.4%, P < 0.001) were significantly associated with FSD. Meta-regression revealed that the primary sources of heterogeneity in FSD are attributable to adjustments for covariates, study design, and study population.

CONCLUSION

Our meta-analysis indicated that patients with CVD suffer from a greater risk of developing FSD. Meanwhile, we validated these findings in longitudinal queues. Notably, conditions such as hypertension, stroke, and myocardial infarction demonstrated a significant association with the incidence of FSD.

Sexual experience in patients with coronary heart disease: a descriptive phenomenological study

Sex is an essential part of life and is a basic demand for human beings. Coronary heart disease can have an impact on patients' sexual lives; however, not much attention has been paid to it in China, and few studies have been conducted on this topic. Therefore, this study used a qualitative approach to understand the sexual experience of patients after the illness, thus laying the foundation for the development of relevant measures. Semi-structured interviews were conducted with 14 patients. Descriptive phenomenological methods were employed to collect data and explore the sexual experience of patients with coronary heart disease. A total of 4 thematic groups, 9 themes, and 23 subthemes were extracted. The four thematic groups were independent and cross-influenced. In these groups, alterations in the sexual experience, including the change in sexual physiology and psychological state, were affected by the lack of knowledge, age, disease, and other factors. Furthermore, the patient's perception of sexuality affected the quality of sexual life after the illness. The sexual experience of patients with coronary heart disease and its influencing factors, such as age, disease factors, and lack of related knowledge, were described. The findings are expected to aid in formulating targeted and personalized intervention measures.

A Systematic Review on the Relationship Between Physical Activity and Sexual Function in Adults

Sexual function is a vital component of overall well-being and quality of life. Physical activity is known to have a profound influence on various aspects of health, but its impact on sexual function in the general population remains an under-explored area. This systematic review seeks to thoroughly examine existing evidence, aiming to establish the correlation between physical activity and sexual function in both male and female adults. We conducted a comprehensive search of electronic databases and relevant sources, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eligible studies were those that investigated the effects of physical activity on sexual function using the International Index of Erectile Dysfunction (IIEF-5) questionnaire and the Female Sexual Function Index (FSFI). Quality assessment was performed on the included studies, and the findings were synthesized through qualitative analysis. The review identified 12 randomized controlled trials, primarily focusing on males, with interventions ranging from home-based walking to structured exercise training. Only two studies were conducted among females. The most recommended exercise was aerobic exercise. Consistent aerobic exercise proves to be a hopeful and efficient non-drug intervention for enhancing erectile function in men. However, when considering the effects of physical exercise programs on sexual function and the quality of sexual life of females, the results present challenges in drawing clear conclusions. Health policymakers play an important role in providing guidelines and recommendations to healthcare professionals, encouraging them to prescribe exercise as a preferable alternative to pharmacological treatments for enhancing sexual functions in both men and women.
