Improvement in Sexual Dysfunction in Patients With Hypertrophic Cardiomyopathy Undergoing Septal Myectomy: A Prospective Study.

BACKGROUND

Septal myectomy improves symptoms in the majority of patients with obstructive hypertrophic cardiomyopathy (HCM), but there are limited prospective data on functional outcomes after operation.

OBJECTIVES

The authors investigated quality of life measures and prevalence of sexual dysfunction before and after septal myectomy for obstructive HCM.

METHODS

Between January 2018 and October 2019, 436 patients underwent transaortic septal myectomy at our clinic. All patients were screened for eligibility, and 197 (45.2%) were enrolled in this prospective survey study. Patients received a questionnaire pertaining to quality of life and sexual health before and within 4 to 6 months postoperatively, and 113 (57.4%) completed the follow-up survey.

RESULTS

The mean age of the 54 (47.8%) women and 59 (52.2%) men was 54.7 ± 14.1 years. Quality of life, including both mental and physical components, improved significantly in both men (P < 0.001) and women (P < 0.001). Women reported mild sexual dysfunction at baseline, and following septal myectomy, they experienced significant (P < 0.05) improvement in most domains pertaining to sexual health. In men, the International Index of Erectile Function median score was 23 (IQR: 7.0-29.5), which is consistent with mild dysfunction at baseline, and there was significant improvement following surgery in young (age ≤55 years) men (P < 0.001).

CONCLUSIONS

Quality of life is significantly improved following septal myectomy in patients with obstructive HCM. Both women and men reported mild sexual dysfunction at baseline, and women and younger men (age ≤55 years) experienced significant improvements in sexual health.
