Takeaway

  • Endometriosis is associated with an increased risk of composite cardiovascular disease (CVD), ischaemic heart disease (IHD), cerebrovascular disease, arrhythmia and hypertension.

  • No association was found between endometriosis and risk of heart failure (HF).

Why this matters

  • Findings suggest that young women with endometriosis are a potential target group for CVD risk assessment and prevention.

Study design

  • This retrospective cohort study included 56,090 women with endometriosis (age, 16-50 years) and 223,669 matched control participants without endometriosis from The Health Improvement Network (THIN) database, UK.

  • Women aged 16-50 years were followed from 1995 to 2018.

  • Primary outcome was composite CVD including IHD, HF and cerebrovascular disease.

  • Secondary outcomes were arrhythmia, hypertension and mortality.

  • Funding: None.

Key results

  • The annual incidence of endometriosis was 12.3 per 10,000 person-years in 1998 and 11.5 per 10,000 person-years in 2017.

  • The annual prevalence of endometriosis gradually increased from 119.7 per 10,000 population in 1998 to 201.3 per 10,000 population in 2017.

  • Women with endometriosis vs those without were at an increased of (adjusted HR [aHR]; 95% CI):

    • composite CVD (1.24; 1.14-1.37);

    • IHD (1.40; 1.22-1.61);

    • cerebrovascular disease (1.19; 1.04-1.36);

    • arrhythmia (1.26; 1.11-1.43); and

    • hypertension (1.12; 1.07-1.17).

  • No significant association was seen between endometriosis and risk of HF (aHR, 0.76; 95% CI, 0.54-1.07).

  • Women with endometriosis vs those without were at a lower risk of all-cause mortality (aHR, 0.66; 95% CI, 0.59-0.74).

Limitations

  • Retrospective design.

  • Study could not distinguish surgically confirmed cases from cases diagnosed through other means.
