Starting Antihypertensive Drug Treatment With Combination Therapy: Controversies in Hypertension - Con Side of the Argument

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.

Improved Persistence to Medication, Decreased Cardiovascular Events and Reduced All-Cause Mortality in Hypertensive Patients With Use of Single-Pill Combinations: Results From the START-Study

BACKGROUND

Single-pill combination improves adherence and persistence to medication in hypertension. It remains unclear whether this also reduces cardiovascular outcomes and all-cause mortality. We analyzed whether single-pill combinations are superior to identical multiple pills on persistence to medication, cardiovascular outcomes, and all-cause mortality.

METHODS

This was a retrospective claims data (German AOK PLUS) analysis. Data from hypertensive patients ≥18 years treated with renin-angiotensin system combinations given as single pill or identical multipills covering the years 2012 to 2018 were analyzed and followed up to at least 1 year. After 1:1 propensity score matching, persistence to medication, cardiovascular events, and all-cause mortality were compared using non-parametric tests. Results were reported as incidence rate ratios and hazard ratios.

RESULTS

After propensity score matching data from 57 998 patients were analyzed: 10 801 patients received valsartan/amlodipine, 1026 candesartan/amlodipine, 15 349 ramipril/amlodipine, and 1823 amlodipine/valsartan/hydrochlorothiazide as single pill or identical multipill. No relevant differences in patient characteristics were observed within the 4 groups. In all groups, a significant lower all-cause mortality, a significant a higher persistence to medication, a significant lower event rate in 15 out of 20 comparisons, and a tendency in the remaining 5 comparisons was observed under single pills compared with multipill combinations.

CONCLUSIONS

Antihypertensive combination therapy reduces all-cause mortality and cardiovascular events when provided as single pill compared to identical drugs as multipills. This strongly supports the European Society of Cardiology/European Society of Hypertension and International Society of Hypertension guidelines recommending the use of a single-pill combination and thus should be more rigorously implemented into daily clinical practice.

Prevalence of hypertension in Iran: An updated systematic review and meta-analysis of community-based studies

Background

Hypertension (HTN) is one of the primary risk factors for heart disease and stroke worldwide. The present meta-analysis was aimed to systematically review and statistically estimate the prevalence rate of pre-hypertension (PHTN) and HTN in the Iranian child/adolescent and adult age groups.

Methods

In this study, four International databases, including PubMed, Scopus, Web of Science, and Cochrane, as well as three Iranian databases, including SID, Magiran, and IranMedex, were separately investigated for articles published before January 2021. Also, we estimated the pooled effect size for the prevalence of PHTN and HTN in children/adolescent and adult age groups. Stata software (version 14.0) was used for all statistical analyses.

Results

From a total of 1185 articles found in database searches, fifty-one were included in the meta-analysis. The prevalence of HTN in the Iranian adult population was 26.26% (25.11 % and 26.22 % for women and men, respectively). Meanwhile, the prevalence of PHTN and HTN in the child/adolescent age group was 8.97% (95% CI 7.33 - 10.61) and 8.98% (95% CI 7.59 - 10.36), respectively.

Conclusions

This study provides information which can be used for various purposes, including study designing. Further nationwide surveys should be carried out to obtain accurate information on the HTN prevalence rate, particularly based on the American College of Cardiology /American Heart Association guidelines in the Iranian population.

Comparison between the world health organization (WHO) and international society of hypertension (ISH) guidelines for hypertension

The global burden of hypertension remains an unsolved problem, especially in low- and middle-income countries (LMICs). For this reason, clinical practice guidelines containing the latest evidence-based recommendations are crucial in the management of hypertension. It is noteworthy that guidelines simply translated from those of high-income countries (HICs) are not the solution to the problem of hypertension in LMICs. Among the numerous guidelines available, those of the World Health Organisation and the International Society of Hypertension are the latest to be published as of the writing of this article. In this review, we conducted both general and specific comparisons between the recommendations supplied by both guidelines. Differences in aspects of hypertension management such as the timing of antihypertensive initiation, assessment of comorbidities and cardiovascular risk factors, pharmacological therapy selection, and blood pressure target and reassessment are explored. Lastly, the implications of the differences found between the two guidelines in both LMICs and HICs are discussed.Key messagesCurrently, with low treatment and control rates, hypertension remains a burden in low- and middle-income countries (LMICs).The lack of customised guidelines for LMICs cannot be solved simply by adopting guidelines from high-income countries.The World Health Organisation (WHO) recently published a clinical guideline for the pharmacological management of hypertension in LMICs. We compare select recommendations from the guidelines to those published by the International Society of Hypertension.

DPP3: From biomarker to therapeutic target of cardiovascular diseases

Cardiovascular disease is the leading cause of death globally among non-communicable diseases, which imposes a serious socioeconomic burden on patients and the healthcare system. Therefore, finding new strategies for preventing and treating cardiovascular diseases is of great significance in reducing the number of deaths and disabilities worldwide. Dipeptidyl peptidase 3 (DPP3) is the first zinc-dependent peptidase found among DPPs, mainly distributes within the cytoplasm. With the unique HEXXGH catalytic sequence, it is associated with the degradation of oligopeptides with 4 to 10 amino acids residues. Accumulating evidences have demonstrated that DPP3 plays a significant role in almost all cellular activities and pathophysiological mechanisms. Regarding the role of DPP3 in cardiovascular diseases, it is currently mainly used as a biomarker for poor prognosis in patients with cardiovascular diseases, suggesting that the level of DPP3 concentration in plasma is closely linked to the mortality of diseases such as cardiogenic shock and heart failure. Interestingly, it has been reported recently that DPP3 regulates blood pressure by interacting with the renin-angiotensin system. In addition, DPP3 also participates in the processes of pain signaling, inflammation, and oxidative stress. But the exact mechanism by which DPP3 affects cardiovascular function is not clear. Hence, this review summarizes the recent advances in the structure and catalytic activity of DPP3 and its extensive biological functions, especially its role as a therapeutic target in cardiovascular diseases. It will provide a theoretical basis for exploring the potential value of DPP3 as a therapeutic target for cardiovascular diseases.
