| アブストラクト | OBJECTIVE: To investigate the long-term risk of developing hypertension and cardiovascular disease (CVD) among those women who suffered a postpartum haemorrhage (PPH) compared with those women who did not. DESIGN: Population-based longitudinal open cohort study. SETTING: English primary care (The Health Improvement Network (THIN)) and secondary care (Hospital Episode Statistics (HES)) databases. POPULATION: Women exposed to PPH during the study period matched for age and date of delivery, and unexposed. METHODS: We conducted an open cohort study using linked primary care THIN and HES Databases, from 1 January 1997 to 31 January 2018. A total of 42 327 women were included: 14 109 of them exposed to PPH during the study period and 28 218 matched for age and date of delivery, and unexposed to PPH. HRs for cardiovascular outcomes among women who had and did not have PPH were estimated after controlling for covariates using multivariate Cox regression models. OUTCOME MEASURES: Risk of hypertensive disease, ischaemic heart disease, heart failure, stroke or transient ischaemic attack. RESULTS: During a median follow-up of over 4 years, there was no significant difference in the risk of hypertensive disease after adjustment for covariates (adjusted HR (aHR): 1.03 (95% CI: 0.87 to 1.22); p=0.71). We also did not observe a statistically significant difference in the risk of composite CVD (ischaemic heart disease, heart failure, stroke or transient ischaemic attack) between the exposed and the unexposed cohort (aHR: 0.86 (95% CI: 0.52 to 1.43; p=0.57). CONCLUSION: Over a median follow-up of 4 years, we did not observe an association between PPH and hypertension or CVD. |
