Sex disparities in hypertension prevalence, blood pressure trajectories and the effects of anti-hypertensive treatment.

INTRODUCTION: Sex differences in blood pressure (BP), hypertension and hypertension mediated cardiovascular complications have become an increasingly important focus of attention. This narrative review gives an overview of current studies on this topic, with the aim to provide a deeper understanding of the sex-based disparities in hypertension with essential insights for refining prevention and management strategies for both men and women. METHODS AND RESULTS: We searched Medline, Embase and the Cochrane libray on sex differences in BP-trajectories and hypertension prevalence. In the past decade various population-based studies have revealed substantial sex-disparities in BP-trajectories throughout life with women having a larger increase in hypertension prevalence after 30 years of age and a stronger association between BP and cardiovascular disease (CVD). In general, the effects of antihypertensive treatment appear to be consistent across sexes in different populations, although there remains uncertainty about differences in the efficacy of BP lowering drugs below 55 years of age. CONCLUSION: The current uniform approach to the diagnosis and management of hypertension in both sexes neglects the distinctions in hypertension, while the differences underscore the need for sex-specific recommendations, particularly for younger individuals. A major limitation hampering insights into sex differences in BP-related outcomes is the lack of sex-stratified analyses or an adequate representation of women. Additional large-scale, longitudinal studies are imperative.

[Three-component tear substitute as preoperative support in glaucoma surgery]. / Primenenie trekhkomponentnogo slezozamenitelya v meditsinskom soprovozhdenii khirurgii glaukomy.

PURPOSE: This study investigates the effect of preoperative preparation with the three-component tear substitute Stillavit on the outcomes of glaucoma surgery in patients on long-term topical glaucoma therapy. MATERIAL AND METHODS: The study included 63 patients (63 eyes) with glaucoma, among them 30 (30 eyes) were women and 33 (33 eyes) were men. Group 1 consisted of 33 patients (33 eyes) receiving long-term topical antihypertensive therapy with preservatives and tear substitute Stillavit 3 times a day for 1 month as preoperative preparation. Group 2 included 30 patients (30 eyes) receiving similar antihypertensive therapy who were not prescribed preoperative medications. All patients underwent a comprehensive ophthalmological examination and computer tomography of the filtering blebs (FB) on Visante system (Carl Zeiss Meditec, Germany) before surgery, as well as 1 week, 1, 3, and 6 months after surgery. RESULTS: Mean intraocular pressure (IOP) elevation at 6 months postoperatively was significantly higher in the group that did not undergo preoperative preparation with a tear substitute, compared to the group of patients who received the tear substitute Stillavit preoperatively. According to anterior segment optical coherence tomography, a greater number of favorable diffuse FB were noted in the group that received the tear substitute Stillavit in preparation for surgery - 87.9%, while in group 2 (without preparation) - 66.7%. Odds ratio calculation between the two groups revealed that preoperative preparation with the tear substitute Stillavit reduced the odds of IOP elevation to 20 mm Hg or higher at 3 months postoperatively by more than 10 times. CONCLUSION: The use of tear substitute Stillavit in preparation for anti-glaucoma surgery reduces the chances of IOP elevation in the early postoperative period by more than 10 times, which may indicate a reduction in the rate of FB scarring due to the beneficial effect of the drug's components on the precorneal tear film.

PERSONIFICATION OF ANTIHYPERTENSIVE THERAPY IN ISCHEMIC CEREBRAL STROKE.

The purpose of the study is to optimize monitoring and personalize antihypertensive therapy in patients with severe ischemic cerebral stroke (ICS). We examined 37 patients with ICS, average age 74,1±1,3 years, who received treatment in intensive care wards of the stroke department with general neurology beds of the Municipal Non-Profit Enterprise "City Hospital № 9" of the Zaporizhzhia City Council. There were 16 men (43,2%), average age 71,9±2,1 years; women - 21 (56,8%), average age 75,8±1.6 years. Personification of antihypertensive therapy for severe ICS was carried out based on the etiology of hypertensive hemodynamic disorders: hyperkinetic type of arterial hypertension (Cardiac index ≥ 3,80 L×min-1×m-2) or hypokinetic type of arterial hypertension (Cardiac index ≤ 2,98 L×min-1×m-2). In patients with severe ICS and hyperkinetic type of arterial hypertension, initial hemodynamic parameters were characterized by Mean arterial pressure (MAP) of 111,4 ± 1,4 mm Hg; Heart rate (HR) of 107,2±1,6 min; Cardiac index (CI) 6,74±0,27 L×min-1×m-2; the Total peripheral vascular resistance (TPVR) is 674±36 dyn×sec-1×cm-5. For the purpose of antihypertensive correction of the hyperkinetic type of arterial hypertension (CI ≥ 3,80 L×min-1×m-2), a solution of Magnesium Sulfate was used intravenously at a dose of 2500-5000 mg×day-1 in combination with Bisoprolol 5-10 mg×day-1 orally. This made it possible to stabilize hemodynamic parameters by the end of intensive therapy within the limits of eukinetic values: MAP 95,2±1,5 mm Hg (p<0,05); HR 81,9±1,5 min (p<0,05); CI 3,60±0,15 L×min-1×m-2 (p<0,05); TPVR is 1079±58 dyn×sec-1×cm-5 (p<0,05). In patients with severe ICS and hypokinetic type of arterial hypertension, initial hemodynamic parameters were characterized by MAP of 117,7±2,8 mm Hg; HR of 76,7±1,5 min; CI 2,74±0,18 L×min-1×m-2; TPVR is 1754±123 dyn×sec-1×cm-5. For the purpose of antihypertensive correction of the hypokinetic type of arterial hypertension (CI≤2,98 L×min-1×m-2), a solution of Ebrantil was used intravenously as a bolus of 1,25-2,5 mg with a further infusion of 5-40 mg×hour-1. This made it possible to stabilize hemodynamic parameters by the end of intensive therapy within the limits of eukinetic values: MAP 92,7 ± 1,7 mm Hg (p<0,05); HR 81,4 ± 0,9 min (p<0,05); CI 3,65±0,16 L×min-1×m-2 (p<0,05); TPVR is 1036±46 dyn×sec-1×cm-5 (p<0,05).

Effect of brimonidine on vascular density and imagej-derived flow index of optic nerve head and macula in primary open angle glaucoma.

PURPOSE: To study the effect of brimonidine on vascular density and flow index of optic nerve head (ONH) and macula in primary open angle glaucoma (POAG) using optical coherence tomography angiography (OCTA). METHODS: Twenty-three brimonidine-naïve POAG patients were started on brimonidine. They underwent OCTA ONH and macula before commencing brimonidine and one month thereafter. Systemic arterial blood pressure (SABP) and intraocular pressure (IOP) were measured at each visit to calculate mean ocular perfusion pressure (MOPP). The OCT angiograms were analyzed using ImageJ software to calculate ONH and macular flow indices. RESULTS: Thirty-seven eyes (23 patients) with a mean age of 56.7 ± 12.49 years were included of whom 60.8% were males. Brimonidine was associated with an increase in the superficial flow index (SFI) (P-value = 0.02) and optic nerve head flow index (ONHFI) (P-value = 0.01). Also, superficial vascular density (SVD) for whole image, superior-hemi and fovea increased (P-value = 0.03, 0.02, 0.03 respectively). ONH inferior-hemi vascular density decreased (P-value = 0.01) despite an increase in inferior quadrant retinal nerve fiber layer thickness (RNFLT) (P-value = 0.03). There was no statistically significant correlation between flow indices and MOPP at baseline and follow-up. A moderate negative correlation was found between SVD and DVD at the fovea and MOPP at baseline and follow-up (P-value = 0.03, 0.05) (P-value = 0.02, 0.01) respectively. CONCLUSIONS: Brimonidine was associated with an increase in SFI, ONHFI and SVD indicating improved GCC and RNFL perfusion in POAG. Despite the increase in inferior quadrant RNFLT, the concomitant decrease in inferior-hemi ONHVD precluded a conclusion of hemodynamically-mediated improvement of RNFLT.

Pregnancy Outcomes of Nifedipine Compared With Labetalol for Oral Treatment of Mild Chronic Hypertension.

OBJECTIVE: To evaluate maternal and neonatal outcomes by type of antihypertensive used in participants of the CHAP (Chronic Hypertension in Pregnancy) trial. METHODS: We conducted a planned secondary analysis of CHAP, an open-label, multicenter, randomized trial of antihypertensive treatment compared with standard care (no treatment unless severe hypertension developed) in pregnant patients with mild chronic hypertension (blood pressure 140-159/90-104 mm Hg before 20 weeks of gestation) and singleton pregnancies. We performed three comparisons based on medications prescribed at enrollment: labetalol compared with standard care, nifedipine compared with standard care, and labetalol compared with nifedipine. Although active compared with standard care groups were randomized, medication assignment within the active treatment group was not random but based on clinician or patient preference. The primary outcome was the occurrence of superimposed preeclampsia with severe features, preterm birth before 35 weeks of gestation, placental abruption, or fetal or neonatal death. The key secondary outcome was small for gestational age (SGA) neonates. We also compared medication adverse effects between groups. Relative risks (RRs) and 95% CIs were estimated with log binomial regression to adjust for confounding. RESULTS: Of 2,292 participants analyzed, 720 (31.4%) received labetalol, 417 (18.2%) received nifedipine, and 1,155 (50.4%) received no treatment. The mean gestational age at enrollment was 10.5±3.7 weeks; nearly half of participants (47.5%) identified as non-Hispanic Black; and 44.5% used aspirin. The primary outcome occurred in 217 (30.1%), 130 (31.2%), and 427 (37.0%) in the labetalol, nifedipine, and standard care groups, respectively. Risk of the primary outcome was lower among those receiving treatment (labetalol use vs standard adjusted RR 0.82, 95% CI, 0.72-0.94; nifedipine use vs standard adjusted RR 0.84, 95% CI, 0.71-0.99), but there was no significant difference in risk when labetalol was compared with nifedipine (adjusted RR 0.98, 95% CI, 0.82-1.18). There were no significant differences in SGA or serious adverse events between participants receiving labetalol and those receiving nifedipine. CONCLUSION: No significant differences in predetermined maternal or neonatal outcomes were detected on the basis of the use of labetalol or nifedipine for treatment of chronic hypertension in pregnancy.

Adherence to antihypertensive medication and its associated factors among patients with hypertension attending a tertiary hospital in Kathmandu, Nepal.

Hypertension is a major risk factor for cardiovascular disease, which is the leading cause of premature mortality and morbidity globally. Despite the evidences of the availability of effective treatment for hypertension, its management remains suboptimal. Medication adherence is the most crucial factor for blood pressure control. It is important to identify the factors associated with adherence to antihypertensive treatment for better management. Hence, this study assessed the level of antihypertensive medication adherence and its associated factors among patients with hypertension visiting a tertiary-level hospital in Kathmandu, Nepal. An analytical cross-sectional study was carried out among 308 diagnosed patients with hypertension who were prescribed antihypertensive medication. The Morisky Medication Adherence Scale (MMAS-8) was used to assess medication adherence. Data was collected through face-to-face interviews and analysed using SPSS v26. A bivariate and multivariate logistic regression model was used to assess the factors associated with low medication adherence. More than half (61%) of the study participants had moderate to high levels of medication adherence. Upon bivariate analysis, there was a significant association between presence of side effects, blood pressure status, forgetfulness, high cost, fear of taking medicine lifelong and irregular follow-up with a low level of adherence. Upon multivariate the logistic regression analysis, forgetfulness [Adjusted Odd's Ratio (AOR) 22.5, 95% Confidence Interval(CI) 10.56-47.86], high cost (AOR 3.8, 95%CI 1.25-11.60) and fear of taking medicines lifelong (AOR 6.04, 95%CI 2.96-12.33) were found to be associated factors of low level of adherence. There is an urgency to develop evidence-based strategies to improve the level of adherence to antihypertensive medications among patients with hypertension. Strategies like reminder messaging, setting alarms, expanding the scope of national health insurance and proper counselling to reduce fear could help to improve medication adherence. Hence, the feasibility and effectiveness of such intervention should be explored in future studies.

Antihypertensive utilization patterns among pregnant persons with pre-existing hypertension in the US: A population-based study.

BACKGROUND: Hypertension among persons with childbearing potential is on the rise. Maintaining proper blood pressure during pregnancy is vital to prevent maternal and neonatal complications. Yet, limited evidence on the risk-benefit of various antihypertensives presents challenges for informed decision-making during this critical period. This study aimed to examine the utilization patterns of different classes of antihypertensives among persons with pre-existing hypertension before, during, and after pregnancy. METHODS: We used MarketScan® Commercial Database 2011-2020 to analyze antihypertensive utilization among pregnant persons aged 12 to 55 identified via a validated algorithm. Pre-existing hypertension was defined as ≥1 inpatient or ≥2 outpatient encounters for hypertension within the 180 days preceding the LMP. Antihypertensive utilization was described during target periods: 0-3 months (0-3M) before pregnancy, 1st/2nd/3rd trimester (T1/2/3), 0-3M, and 4-6M after pregnancy. RESULTS: We identified 1,950,292 pregnancies, of which 20,576 (12,978 live and 7,598 non-live) had pre-existing hypertension. Both groups had similar antihypertensive use (80.1% and 81.0%, respectively) during the 6 months before pregnancy (baseline). For live-birth pregnancies, 13.9% of baseline users discontinued treatment during pregnancy, while 28.9% of non-users initiated antihypertensives during pregnancy, and 17.2% started postpartum. Before pregnancy, the predominant antihypertensives included thiazide diuretics (21.9%), combined α- and ß-blockers (18.4%), and dihydropyridines (16.2%). During pregnancy, thiazide diuretics, cardioselective ß-blockers, and ACE inhibitors declined (T3: 3.0%, 4.2%, and 0.8%). Dihydropyridine use was steady during pregnancy, but preference shifted from amlodipine to nifedipine in T3 (2.2.% vs.10.8%). Central α2-agonists increased during pregnancy (up to 15.2% in T3) compared to both pre- (9.8%) and post-pregnancy (5.7%). ARBs mirrored ACE inhibitors, with less than 1% utilization in later trimesters. Combination agents dropped from 10.8% pre-pregnancy to 0.8% in T3, then rebounded to 7.3% post-pregnancy. CONCLUSION: Research is warranted to evaluate the choice of antihypertensives and optimal timing to switch to safer alternatives, considering maternal and fetal outcomes.

Orthostatic Hypotension and Antihypertensive Treatment in Lung Transplant Recipients: A Cross-Sectional Study.

OBJECTIVES: Lung transplant is the ultimate treatment of many end-stage lung diseases. Calcineurin inhibitors, crucial in immunosuppression for lung transplant recipients, are linked to secondary hypertension, necessitating antihypertensive treatment. In addition, lung transplant recipients frequently experience orthostatic hypotension, occasionally stemming from autonomic dysfunction, but also commonly attributed as a negative side effect of antihypertensive treatment. Our study aimed to evaluate the frequency of orthostatic blood pressure irregularities and investigate the involvement of antihypertensive treatment as a potential risk factor in the occurrence among lung transplant recipients. MATERIALS AND METHODS: Fifty-six consecutive lung transplant recipients, both inpatient and outpatient, at the University Hospital Zurich (Switzerland) were monitored from 1999 to 2013. Transplant recipients underwent a Schellong test (an active standing test). Our evaluation encompassed their initial traits, such as the existence of supine hypertension. We computed the odds ratio for the comparison of the likelihood of experiencing orthostatic hypotension while using a minimum of 1 type of antihypertensive medication versus absence of antihypertensive drugs. RESULTS: Of the lung transplant recipients, 25% showed a positive Schellong test. Within this group, 64% had supine hypertension, and 29% displayed symptoms of orthostatic hypotension. Among the patients, 71% were using at least 1 type of antihypertensive medication. The odds ratio for showing orthostatic hypotension while taking at least 1 type of antihypertensive drug versus the absence of antihypertensive medications was 1.64 (95% exact CI, 0.39-6.90) with P = .50. This finding remained consistent regardless of age, sex, inpatient or outpatient status, and the duration since transplant. CONCLUSIONS: Orthostatic blood pressure dysregulation is prevalent among lung transplant recipients, frequently without noticeable symptoms. In our cohort, the use of antihypertensive medications did not elevate the risk of orthostatic hypotension.

Medication adherence, related factors and outcomes among patients with pulmonary arterial hypertension or chronic thromboembolic pulmonary hypertension: a systematic review.

INTRODUCTION: Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are life-threatening conditions that can progress to death without treatment. Although strong medication adherence (MA) is known to enhance outcomes in chronic illnesses, its association with PAH and CTEPH was sporadically explored. This study aims to examine the MA of patients with PAH or CTEPH, identify factors associated with low adherence and explore the resulting outcomes. METHODS: A systematic review was conducted by searching multiple databases (Medline, Embase, Cochrane Central, ClinicalTrials.gov, Scopus, Web of Science and Google Scholar) from 6 March 1998 to 6 July 2023. We included studies reporting MA as primary or secondary end-points. Study selection, data extraction and methodological quality assessment were performed in duplicate. RESULTS: 20 studies involving 22 675 patients met the inclusion criteria. Heterogeneity was observed, particularly in the methods employed. MA means ranged from 0.62 to 0.96, with the proportion of patients exhibiting high MA varying from 40% (95% CI 35-45%) to 94% (95% CI 88-97%). Factors associated with low adherence included increased treatment frequency, time since diagnosis and co-payment. High MA seems to be associated with reduced hospitalisation rates, inpatient stays, outpatient visits and healthcare costs. CONCLUSIONS: This systematic review underscores the heterogeneity of MA across studies. Nevertheless, the findings suggest that high MA could improve patients' clinical outcomes and alleviate the economic burden. Identifying factors consistently associated with poor MA could strengthen educational efforts for these patients, ultimately contributing to improved outcomes.

Prospective validation of a mobile health application for blood pressure management in patients with hypertensive disorders of pregnancy: study protocol for a randomized controlled trial.

BACKGROUND: Hypertensive disorders of pregnancy (HDP) pose significant risks to both maternal and fetal health, contributing to global morbidity and mortality. Management of HDP is complex, particularly because of concerns regarding potential negative effects on utero-placental circulation and limited therapeutic options due to fetal safety. Our study investigates whether blood pressure monitoring through a mobile health (mHealth) application can aid in addressing the challenges of blood pressure management in pregnant individuals with HDP. Additionally, we aim to assess whether this intervention can improve short-term maternal and fetal outcomes and potentially mitigate long-term cardiovascular consequences. METHODS: This prospective, randomized, single-center trial will include 580 pregnant participants who meet the HDP criteria or who have a heightened risk of pregnancy-related hypertension due to factors such as multiple pregnancies, obesity, diabetes, or a history of HDP in prior pregnancies leading to preterm birth. Participants will be randomized to either the mHealth intervention group or the standard care group. The primary endpoint is the difference in systolic blood pressure from enrollment to 1 month after childbirth. The secondary endpoints include various blood pressure parameters, obstetric outcomes, body mass index trajectory, step counts, mood assessment, and drug adherence. CONCLUSIONS: This study emphasizes the potential of mHealth interventions, such as the Heart4U application, to improve blood pressure management in pregnant individuals with HDP. By leveraging technology to enhance engagement, communication, and monitoring, this study aims to positively impact maternal, fetal, and postpartum outcomes associated with HDP. This innovative approach demonstrates the potential of personalized technology-driven solutions for managing complex health conditions.

Effective Management of Severe Amlodipine/Atenolol Overdose with Intravenous Calcium, Hyperinsulinemic Euglycemia Therapy, and Continuous Veno-Venous Hemodialysis: A Case Report.

BACKGROUND Amlodipine, a calcium channel blocker, and atenolol, a beta blocker, are commonly used as a fixed drug combination (FDC) to treat hypertension. Intentional or non-intentional overdose of amlodipine-atenolol results in hypotension and myocardial depression with a high risk of mortality. This report describes a 64-year-old man with an overdose of amlodipine-atenolol, presenting as an emergency with hypotension, bradycardia, and severe metabolic acidosis. He was successfully treated with intravenous calcium chloride infusion, hyperinsulinemia euglycemia therapy (HIE), and continuous veno-venous hemodialysis (CVVHD). CASE REPORT A 64-year-old man was diagnosed with essential hypertension 1 week prior to the admission. He had been prescribed 1 FDC tablet of amlodipine and atenolol (5+50 mg) per day; however, he took 1 table of the FDC per day for 3 days and then took 3-4 tablets each day during the next 4 days. He was brought to the hospital with hypotension, bradycardia, and severe metabolic acidosis and was diagnosed with amlodipine-atenolol overdose. He was treated with intravenous calcium chloride infusion, HIE, and CVVHD. His hemodynamics started to improve after administering these therapies for 6 h. Inotropes were gradually tapered off and stopped. He was extubated on day 5 and recovered completely. CONCLUSIONS This report shows the serious effects amlodipine-atenolol overdose and the challenges of emergency patient management. An overdose of FDC of amlodipine and atenolol can cause cardiovascular collapse and severe metabolic acidosis. Timely and aggressive management with intravenous calcium infusion, HIE, and CVVHD is essential.

A Survey of Availability and Affordability of Polypills for Cardiovascular Disease in Selected Countries.

Background: The recent inclusion of polypills-fixed-dose combinations of antihypertensive medicines and a statin with or without aspirin-in the World Health Organization's Essential Medicines List (EML) reiterates the potential of this approach to improve global treatment coverage for cardiovascular diseases (CVDs). Although there exists extensive evidence on the effectiveness, safety and acceptability of polypills, there has been no research to date assessing the real-world availability and affordability of polypills globally. Methods: We conducted a cross-sectional survey, based on the WHO/Health Action International methodology, in 13 countries around the world. In the surveyed countries, we first ascertained whether any polypill was authorised for marketing and/or included in EMLs and clinical guidelines. In each country, we collected retail and price data for polypills from at least one public-sector facility and three private pharmacies using convenience sampling. Polypills were considered unaffordable if the lowest-paid worker spent more than a day's wage to purchase a monthly supply. Results: Polypills were approved for marketing in four of the 13 surveyed countries: Spain, India, Mauritius and Argentina. None of these countries included polypills in national guidelines, formularies, or EMLs. In the four countries, no surveyed public pharmacies stocked polypills. In the private sector, we identified seven unique polypill combinations, marketed by eight different companies. Private sector availability was 100% in Argentina and Spain. Most combinations (n = 5) identified were in India. Combinations found in India and Spain were affordable in the local context. A lowest-paid government worker would spend between 0.2 (India) and 2.8 (Mauritius) days' wages to pay the price for one month's supply of the polypills. Polypills were likely to be affordable if they were manufactured in the same country. Conclusion: Low availability and affordability of polypills in the public sector suggest that implementation remains poor globally. Context-specific multi-disciplinary health system research is required to understand factors affecting polypill implementation and to design and evaluate appropriate implementation strategies.

Effects of the discontinuation of antihypertensive treatment on neuropsychiatric symptoms and quality of life in nursing home residents with dementia (DANTON): a multicentre, open-label, blinded-outcome, randomised controlled trial.

BACKGROUND: Based on observational studies and randomised controlled trials (RCTs), the benefit-harm balance of antihypertensive treatment in older adults with dementia is unclear. OBJECTIVE: To assess whether discontinuing antihypertensive treatment reduces neuropsychiatric symptoms (NPSs) and maintains quality of life (QoL) in nursing home residents with dementia. DESIGN: Open-label, blinded-outcome RCT. Randomisation 1:1, stratified by nursing home organisation and baseline NPS. Trial registration: NL7365. SUBJECTS: Dutch long-term care residents with moderate-to-severe dementia and systolic blood pressure (SBP) ≤160 mmHg during antihypertensive treatment. Exclusion criteria included heart failure NYHA-class-III/IV, recent cardiovascular events/procedures or life expectancy <4 months (planned sample size n = 492). MEASUREMENTS: Co-primary outcomes NPS (Neuropsychiatric Inventory-Nursing Home [NPI-NH]) and QoL (Qualidem) at 16 weeks. RESULTS: From 9 November 2018 to 4 May 2021, 205 participants (median age 85.8 [IQR 79.6-89.5] years; 79.5% female; median SBP 134 [IQR 123-146] mmHg) were randomised to either antihypertensive treatment discontinuation (n = 101) or usual care (n = 104). Safety concerns, combined with lacking benefits, prompted the data safety and monitoring board to advice a premature cessation of randomisation. At 16-week follow-up, no significant differences were found between groups for NPI-NH (adjusted mean difference 1.6 [95% CI -2.3 to 5.6]; P = 0.42) or Qualidem (adjusted mean difference - 2.5 [95% CI -6.0 to 1.0]; P = 0.15). Serious adverse events (SAEs) occurred in 36% (discontinuation) and 24% (usual care) of the participants (adjusted hazard ratio 1.65 [95% CI 0.98-2.79]). All 32-week outcomes favoured usual care. CONCLUSION: Halfway through this study, a non-significant increased SAE risk associated with discontinuing antihypertensive treatment was observed, and an associated interim analysis showed that significant worthwhile health gain for discontinuation of antihypertensive treatment was unlikely. This unbeneficial benefit-harm balance shows that discontinuation of antihypertensive treatment in this context does not appear to be either safe or beneficial enough to be recommended in older adults with dementia.

Cost-effectiveness of single-pill and separate-pill administration of antihypertensive triple combination therapy: a population-based microsimulation study.

BACKGROUND: Single-pill combination (SPC) of three antihypertensive drugs has been shown to improve adherence to therapy compared with free combinations, but little is known about its long-term costs and health consequences. This study aimed to evaluate the lifetime cost-effectiveness profile of a three-drug SPC of an angiotensin-converting enzyme inhibitor, a calcium-channel blocker, and a diuretic vs the corresponding two-pill administration (a two-drug SPC plus a third drug separately) from the Italian payer perspective. METHODS: A cost-effectiveness analysis was conducted using multi-state semi-Markov modeling and microsimulation. Using the healthcare utilization database of the Lombardy Region (Italy), 30,172 and 65,817 patients aged ≥ 40 years who initiated SPC and two-pill combination, respectively, between 2015 and 2018 were identified. The observation period extended from the date of the first drug dispensation until death, emigration, or December 31, 2019. Disease and cost models were parametrized using the study cohort, and a lifetime microsimulation was applied to project costs and life expectancy for the compared strategies, assigning each of them to each cohort member. Costs and life-years gained were discounted by 3%. Probabilistic sensitivity analysis with 1,000 samples was performed to address parameter uncertainty. RESULTS: Compared with the two-pill combination, the SPC increased life expectancy by 0.86 years (95% confidence interval [CI] 0.61-1.14), with a mean cost differential of -€12 (95% CI -9,719-8,131), making it the dominant strategy (ICER = -14, 95% CI -€15,871-€7,113). The cost reduction associated with the SPC was primarily driven by savings in hospitalization costs, amounting to €1,850 (95% CI 17-7,813) and €2,027 (95% CI 19-8,603) for patients treated with the SPC and two-pill combination, respectively. Conversely, drug costs were higher for the SPC (€3,848, 95% CI 574-10,640 vs. €3,710, 95% CI 263-11,955). The cost-effectiveness profile did not significantly change according to age, sex, and clinical status. CONCLUSIONS: The SPC was projected to be cost-effective compared with the two-pill combination at almost all reasonable willingness-to-pay thresholds. As it is currently prescribed to only a few patients, the widespread use of this strategy could result in benefits for both patients and the healthcare system.

Pharmacologic Treatment of Portal Hypertension.

Portal hypertension is the key mechanism driving the transition from compensated to decompensated cirrhosis. In this review, the authors described the pathophysiology of portal hypertension in cirrhosis and the rationale of pharmacologic treatment of portal hypertension. We discussed both etiologic and nonetiologic treatment of portal hypertension and the specific clinical scenarios how nonselective beta-blocker can be used in patients with cirrhosis. Finally, the authors summarized the evidence for emerging alternatives for portal hypertension in patients with cirrhosis.

Cardiovascular Effects of Herbal Products and Their Interaction with Antihypertensive Drugs-Comprehensive Review.

Hypertension is a highly prevalent population-level disease that represents an important risk factor for several cardiovascular complications and occupies a leading position in mortality statistics. Antihypertensive therapy includes a wide variety of drugs. Additionally, the potential antihypertensive and cardioprotective effects of several phytotherapy products have been evaluated, as these could also be a valuable therapeutic option for the prevention, improvement or treatment of hypertension and its complications. The present review includes an evaluation of the cardioprotective and antihypertensive effects of garlic, Aloe vera, green tea, Ginkgo biloba, berberine, ginseng, Nigella sativa, Apium graveolens, thyme, cinnamon and ginger, and their possible interactions with antihypertensive drugs. A literature search was undertaken via the PubMed, Google Scholar, Embase and Cochrane databases. Research articles, systematic reviews and meta-analyses published between 2010 and 2023, in the English, Hungarian, and Romanian languages were selected.

Special considerations, such as comorbid mental health conditions and individualized treatment plans, are also addressed. NPs play a pivotal role in improving outcomes by fostering patient engagement and adherence. By embracing this holistic approach, NPs are poised to enhance the quality of care and well-being of patients with CKD and HTN.

What interventions are effective in reducing development of hypertension and other cardiovascular complications in women who have had hypertensive disorders of pregnancy? A systematic review.

BACKGROUND: Hypertensive disorders of pregnancy (HDP) affect approximately 10-15% of pregnancies and pre-eclampsia affects 3-5% of pregnancies. Women with previous pre-eclampsia or HDP are at increased risk of hypertension (2 to 5 times) and major cardiovascular disease (1.5 to 3 times). There is little guidance on how to reduce this risk. AIM: To establish if there are interventions in women with previous HDP or pre-eclampsia that reduce the risk of developing adverse cardiovascular outcomes. METHOD: A protocol was submitted to PROSPERO; inclusion and exclusion criteria were determined and a search strategy implemented. Primary outcomes were: development of hypertension or change in blood pressure and development of other cardiovascular complications. Records and full texts were screened independently by two reviewers. The Cochrane Risk of Bias tool was used for quality assessment. RESULTS: 3593 articles were screened. Nine articles were included. There were seven randomised-controlled trials and two quasi-experimental studies. One study trialled antihypertensive use, two studies looked at blood pressure monitoring and six studies focused on lifestyle interventions. Three trials reported significant reductions in diastolic blood pressure in the experimental group. No studies looked at the optimal time of intervention or the impact of interventions on the development of other long-term cardiovascular complications. Five studies reported participant feedback. The majority of studies were of low quality. CONCLUSION: Further research needs to explore potential interventions and optimal timing of interventions to reduce cardiovascular risk. Women also need to be consulted about their preferences for discussions about cardiovascular risk and potential interventions.
