Abstract

The association between constipation and cardiovascular risk is unclear. This population-level matched cohort study compared the association of constipation with hypertension and incident cardiovascular events in 541,172 hospitalized patients aged ≥ 60 years. For each constipation admission, one exact age-matched non-constipated admission was randomly selected from all hospitalizations within 2 weeks to form the comparison cohort. The association of constipation with hypertension and cardiovascular events (myocardial infarction, angina, stroke and transient ischemic attack) were analysed using a series of binary logistic regressions adjusting for age, sex, cardiovascular risk factors, gastrointestinal disorders and sociological factors. Patients with constipation had a higher multivariate-adjusted risk for hypertension (odds ratio [OR], 1.96; 95% confidence interval [CI] 1.94-1.99; P < 0.001). Compared to patients with neither constipation nor hypertension, there was a higher multivariate-adjusted risk for cardiovascular events in patients with constipation alone (OR, 1.58; 95% CI 1.55-1.61; P < 0.001) or hypertension alone (OR, 6.12; 95% CI 5.99-6.26; P < 0.001). In patients with both constipation and hypertension, the risk for all cardiovascular events appeared to be additive (OR, 6.53; 95% CI 6.40-6.66; P < 0.001). In conclusion, among hospital patients aged 60 years or older, constipation is linked to an increased risk of hypertension and cardiovascular events. These findings suggest that interventions to address constipation may reduce cardiovascular risk in elderly patients.
