Abstract:
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.

Abstract:
Background: Patients with COPD are susceptible to cardiovascular events and a recent review article has outlined management of Hypertension in the COPD population [Finks S et al. N Engl J Med 2020;382:353-63]. It is not known how the authors’ suggestions translate into practice, so review was undertaken of a UK District General Hospital population.
Aims: The aim was to review management of hypertensive COPD patients; choice of anti-hypertensive medication, and correlations with morbidity and mortality
Methods: This was a retrospective analysis of all COPD patients who presented to hospital with an exacerbation between October and December 2019. Patients without a history of hypertension were excluded.
Results: 151 patients were admitted during this period. 71/151 were known hypertension. 52% were female, Mean Age (SD) 74 (10) years. 83% (n=59/71) were on anti-hypertensive medication/s (AH) of which 44% (n=26/59), 42% (n=25/59), 12% (7/59) and 2% (1/59) were on one, two, three and four AH respectively. 42% (30/71) patients had an exacerbation in the last 12 months and 97% (29/30) were on ≥1 AH. Unadjusted 30 day mortality was 11% (n=8/71) of which 88% (7/8) were on ≥1 AH. n=2/3 patients on beta blockers, n=2/5 on angiotensin receptor blockers (ARB), n=6/12 on calcium channel blockers (CCB), n=3/4 on ACE-inhibitors and 1/1 on Alpha blocker as a single AH had an exacerbation in the last 12 months. More patients on loop diuretics (LD) had chronic type 2 respiratory failure (n=5) or exacerbations in the last 12 months (n=10).
Conclusions:
1.CCB is the most commonly used AH agent
2.Patients on ARBs were least likely to exacerbate
3.LD may contribute to more exacerbations and chronic type 2 respiratory failure
