Abstract:
Hypertension is the most prevalent condition in clinical practice. Hypertension, diabetes, and hypercholesterolaemia are major contributing factors to cardiovascular diseases. They commonly coexist in a single patient. Statins have been used as prominent medicines for the reduction of cardiovascular events. Statins have been shown to reduce blood pressure in patients with hypertension and have lipid-lowering properties in recent articles. Statins reduce blood pressure because of their impact on endothelial function, their interactions with the renin-angiotensin system, and their influence on major artery compliance. This meta-analysis aimed to ascertain the effectiveness and efficacy of statins for managing hypertension in patients with hypertension. Systematic searches were conducted on PubMed, Science Direct, Embase, Cochrane Library, and Google Scholar. Randomized controlled trials, systematic trials, and cohort studies were retrieved using keywords on statins and their use in patients with hypertension. Exclusion criteria included studies that were not in the English language, studies that did not include patients on statins with hypertension, studies that did not provide enough information, technical reports, opinions, or editorials, and studies involving patients < 18 years old. The inclusion criteria were randomized controlled trials, meta-analyses, adult patients aged > 18 years old, and studies that were freely available or through institutional login. This meta-analysis scrutinized 9361 randomized controlled trials, clinical trials, meta-analyses, and systematic reviews, of which 32 articles including 25 randomized controlled trials and seven meta-analyses were included in the final analysis. This meta-analysis of the role of statins in hypertensive patients aimed to determine the outcome of hypertension control along with antihypertensive medication. Our study showed that statins are useful in reducing both systolic and diastolic blood pressure. We used a heterogeneous model for analysis due to variations in the study characteristics. The I2 value was 0.33 (0.76, 0.10) for systolic blood pressure and 0/88 (0.86, 0.90) for diastolic blood pressure. The I2 value for the seven meta-analyses included in the study was 1.79 (2.88, 0.69).

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
