Increasing evidence suggests that endometriosis patients are at higher risk of several chronic diseases. Although the underlying mechanisms are not yet understood, the available data to date suggest that endometriosis is not harmless with respects to women's long-term health. If these relationships are confirmed, these findings may have important implications in screening practices and in the management and care of endometriosis patients.

Background Endometriosis is a prevalent gynecologic disease associated with systemic chronic inflammation, heightened oxidative stress and atherogenic lipid profile that may increase women's risk for Coronary heart disease (CHD). Methods and Results We examined the prospective association between laparoscopically-confirmed endometriosis and subsequent CHD among 116,430 women in the Nurses’ Health Study II (1989-2009). Participants with a history of heart disease and stroke were excluded. Compared to women without endometriosis, women with laparoscopically-confirmed endometriosis had a higher risk of myocardial infarction (relative risk, 1.52; 95% confidence interval, 1.17-1.98), angiographically-confirmed angina (1.91; 1.59-2.29), coronary artery bypass graft surgery/coronary angioplasty procedure/stent (1.35; 1.08-1.69), or any of these CHD endpoints combined (1.62; 1.39-1.89), independent of potential demographic, anthropometric, family history, reproductive, and lifestyle confounders. Relative risk for the combined CHD endpoint was highest among women age ≤40 (3.08; 2.02-4.70), and decreased as age increased (4055, 0.98, 0.56-1.72; p-value, test for heterogeneity=0.001). Having had a hysterectomy/oophorectomy was associated with higher risk of combined CHD compared to not having had a hysterectomy/oophorectomy (1.51, 1.34-1.71). 42% of the association between endometriosis and CHD could be explained by greater frequency of hysterectomy/oophorectomy and earlier age at surgery following endometriosis diagnosis. Conclusions In this large, prospective cohort, laparoscopically-confirmed endometriosis was associated with increased risk of CHD. The association was strongest among young women. Hysterectomy/oophorectomy was associated with higher risk of CHD and could partially explain the association between endometriosis and CHD.

Abstract-An altered hormonal or chronic systemic inflammatory milieu characterizing endometriosis may result in a higher risk of hypercholesterolemia and hypertension. Conversely, elevated low-density lipoprotein in hypercholesterolemia and chronic systemic inflammation resulting from hypertension may increase the risk of endometriosis. We assessed the association of laparoscopically confirmed endometriosis with hypercholesterolemia and hypertension in a large prospective cohort study. In 1989, 116 430 registered female nurses aged 25 to 42 completed the baseline questionnaire and were followed for 20 years. Multivariable Cox proportional hazards models were applied. In 1989, there were 4244 women with laparoscopically confirmed endometriosis and 91 554 women without. After adjusting for demographic, anthropometric, family history, reproductive, dietary, and lifestyle risk factors prospectively, comparing women with laparoscopically confirmed endometriosis to women without, the relative risks were 1.25 (95% confidence interval, 1.21-1.30) for development of hypercholesterolemia and 1.14 (95% confidence interval, 1.09-1.18) for hypertension. Conversely, the relative risks of developing laparoscopically confirmed endometriosis were 1.22 (95% confidence interval, 1.15-1.31) comparing women with hypercholesterolemia to women without and 1.29 (95% confidence interval, 1.18-1.41) comparing women with hypertension to women without. The strength of associations of laparoscopically confirmed endometriosis with hypercholesterolemia or hypertension was strongest among women aged ≤40 and weakened as age increased (P values for interaction <0.001). We observed that ≈45% of the associations between endometriosis and hypercholesterolemia and hypertension could be accounted for by treatment factors after endometriosis diagnosis, including greater frequency of hysterectomy/oophorectomy and earlier age for this surgery. In this large cohort study, laparoscopically confirmed endometriosis was prospectively associated with increased risk of hypercholesterolemia and hypertension. Conversely, hypercholesterolemia and hypertension were prospectively associated with higher risk of laparoscopically confirmed endometriosis. process, which may be contributing to blood pressure elevation. 23 Hence the chronic systemic inflammation in endometriosis may predispose women with endometriosis to a higher risk of hypertension.In sum, women with endometriosis may have higher risk of hypercholesterolemia or hypertension, and women with hypertension or hypercholesterolemia may have a higher risk of endometriosis. We examined these hypotheses in the NHSII (Nurses' Health Study II), an ongoing prospective cohort study. Methods Study PopulationThe NHSII is a prospective cohort study with 116 430 registered female nurses who were 25 to 42 and resided in 14 of the United States at enrollment in 1989. At baseline, participants completed a detailed questionnaire and every 2 years thereafter completed follow-up questionnaires on the incidence of disease out...

An estimated 3.7 million US adults had hyperkalemia in 2014, and this prevalence rate has increased since 2010. In patients with CKD and/or heart failure, the annual prevalence of hyperkalemia was 6.35% in 2014, and about half of all patients with hyperkalemia have either CKD and/or heart failure.

Patients with newly diagnosed HS and general patients with HS experienced a greater indirect burden than matched controls.
