Erectile dysfunction and atrial fibrillation: A systematic review and meta‐analysis

Objective

To investigate the pooled incidence or the prevalence of erectile dysfunction, and to assess the risk of erectile dysfunction in patients with atrial fibrillation.

Methods

A systematic review was carried out in the MEDLINE, EMBASE and Cochrane databases from inception through January 2018 to identify: (i) studies that reported the incidence and/or prevalence of erectile dysfunction in atrial fibrillation patients; or (ii) studies that assessed the association between atrial fibrillation and erectile dysfunction. Pooled odds ratios and 95% confidence intervals were calculated using a random effects model.

Results

Five observational studies (27 841 patients) were enrolled. The pooled estimated prevalence of erectile dysfunction in atrial fibrillation patients was 57% (95% confidence interval 50–64, I² = 0). A study showed an incidence of newly diagnosed erectile dysfunction in atrial fibrillation patients of 0.96% during the mean follow‐up duration of 4.67 ± 3.20 years. There was a significant association of atrial fibrillation with an increased risk of erectile dysfunction, with a pooled odds ratio of 1.79 (95% confidence interval 1.44–2.23, I² = 0%). The data on the risk of atrial fibrillation development in patients with erectile dysfunction were limited. A study showed the comparable risk of atrial fibrillation in patients with erectile dysfunction (odds ratio 1.03, 95% confidence interval 0.67–1.5), when compared with those without erectile dysfunction.

Conclusions

The present study suggests a significant association between erectile dysfunction and atrial fibrillation. The overall estimated prevalence of erectile dysfunction among atrial fibrillation patients is 57%. However, despite limited data, the current evidence suggests a low incidence of new erectile dysfunction in atrial fibrillation patients.
