Current Hypertension Reviews

BACKGROUND: Previous research suggests the role of social determinants of health (SDH) in the prevalence of hypertension. OBJECTIVE: The study aimed to estimate the contribution of SDH to the prevalence of hypertension. METHODS: We recruited 3072 Egyptian public servants who answered a self-administered questionnaire, including hypertension history. We measured the participants' blood pressure with standardized procedures. The logistic regression models were used to assess the associations between SDH and hypertension...

Hypertension is a significant hazardous aspect for several diseases, like cardiovascular disease, kidney failure, and brain disease. Hypertension has become the most lethal condition globally, affecting approximately 1 billion people aged around 30-79 years worldwide. In the year 2022, India was ranked 170th for men and 193rd for women for HTN diagnosis rates among 200 countries worldwide. The main risk factor for cardiac failure and stroke is hypertension. The conventional classes of antihypertensive medications currently available have some side effects...

Oxidative stress is one of the main mechanisms involved in the pathophysiology of arterial hypertension, inducing direct effects on the vasculature, and contributing to endothelial dysfunction and consequent impairment of vascular relaxation. Despite a large number of pharmacological treatments available, intolerable side effects are reported, which makes the use of natural antioxidants a promising and complementary alternative for the prevention and treatment of hypertension. From this perspective, the current review aims to investigate and characterize the main antioxidants of natural origin for the treatment of hypertension...

BACKGROUND: Nebivolol has a dual mechanism of action, exerting a moderate b- blockade effect and reducing peripheral arterial resistance, as a result, the antihypertensive effect of nebivolol may be higher than that of a potent vasodilator CCB such as amlodipine. AIM: The study evaluated the effect of two nebivolol/valsartan on 24 hour ambulatory blood pressure versus amlodipine/valsartan in grade II or III hypertension patients or having uncontrolled BP despite treatment...

AIMS: In this study, we aimed to appraise the effects of interrupting (discontinuing) vs. continuing Angiotensin receptor blockers (ARBs) and Angiotensin-Converting Enzyme Inhibitors (ACEIs) on the hemodynamic changes of patients during and after cataract surgery. METHODS AND MATERIALS: Patients aged 40-70 years, American society of anesthesiologist (ASA) class II, taking ACEI/ARB medications, who were admitted to Khalili hospital (Shiraz, South of Iran) for cataract surgery, were enrolled in the study...

BACKGROUND: Premature ventricular contraction (PVC) is a common arrhythmia that causes a large number of clinical symptoms, adversely impacts the quality of life, and can even initiate serious arrhythmias, such as ventricular tachycardia or ventricular fibrillation. The incidence of premature ventricular contraction is higher in hypertensive patients, particularly if concomitant left ventricular hypertrophy (LVH) is present. OBJECTIVES: This study was conducted on the characteristics of PVC in hypertensive patients with left ventricular hypertrophy and aimed to evaluate the effect of bisoprolol on PVC in Vietnamese patients with hypertension and LVH...

The prevalence of supine and nocturnal hypertension (S-N-HT) is high among patients with orthostatic hypotension (OH), especially in those who have a neurogenic aetiology. The evidence suggests that S-N-HT exacerbates OH, although it is unclear whether pharmacologic treatment of S-N-HT will improve OH. S-N-HT has also been associated with target organ damage. Therefore, assessment and management of S-N-HT should be an integral part of managing OH, but it is often overlooked in clinical practice.

BACKGROUND: An imbalance between angiogenic and anti-angiogenic factors plays a fundamental role in the pathogenesis of preeclampsia (PE). Studies have shown a dysregulation of sFlt-1 and placental growth factor (PlGF) in PE. However, there are differing reports on the levels of these pro-/anti-angiogenic factors in HIV-infected preeclamptic and normotensive pregnancies, possibly due to highly active antiretroviral therapy (HAART) and its immune reconstitution effect. OBJECTIVE: The study ained to investigate the effect of hypertension and ARVs on circulating and placental pro- and anti-angiogenic factors in HIV-infected PE...

The efficiency of blood flowing from the heart depends on its electrical properties. Myocardial electrical activity is associated with the generation of cardiac action potentials in isolated myocardial cells and their coordinated propagation, which are mediated by gap junctions. Atrial fibrillation (AF) is a common cardiac arrhythmia, which causes an aggressive disturbance in cardiac electromechanical function. Moreover, AF increases the risk of stroke and mortality and is a major cause of death. The mechanisms underlying AF involve electrophysiological changes in ion channel expression and function...

The practice of angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACEi/ARB) in COVID-19 hypertensive patients is still an open question for clinicians to answer. The present study was conducted to find out the association between the use of ACEI/ARB and the mortality rate of COVID-19 patients. The search was conducted from December 2019 to October 2020 in PubMed to identify relevant published studies. RevMan 5 was used for the analysis of the data. The random-effect model was used to calculate the odds ratio...

BACKGROUND: Impaired fasting glucose (IFG) predisposes to future development of type 2 diabetes mellitus (T2DM) and may also be associated with increased cardiovascular disease (CVD) risk. Hypertension is an established CVD risk factor. OBJECTIVE: This study aimed to assess the prevalence of IFG and the associated anthropometric and metabolic disturbances in patients with hypertension. METHODS: Consecutive hypertensive patients not on any hypolipidemic treatment and without a diagnosis of T2DM were included...

The production of renin by the principal cells of the collecting duct has widened our understanding of the regulation of intrarenal angiotensin II (Ang II) generation and blood pressure. In the collecting duct, Ang II increases synthesis and secretion of renin by mechanisms involving the activation of Ang II type 1 receptors (AT1R) via stimulation of the PKCα, Ca2+ and cAMP/PKA/CREB pathways. Additionally, paracrine mediators, including vasopressin (AVP), prostaglandins, bradykinin (BK) and atrial natriuretic peptide (ANP) regulate renin in principal cells...

The prorenin receptor (PRR) is a complex multi-functional single transmembrane protein receptor which is ubiquitously expressed in organs and tissues throughout the body. PRR is involved in different cellular mechanism that comprised the generation of Angiotensin II, the activation of Wnt/β-catenin signaling, the stimulation of ERK 1/2 pathway, and the proper functioning of the vacuolar H+-ATPase. Body of evidence support the role of PRR and its soluble form, sPRR, in the classical feature of the metabolic syndrome that includes obesity, hypertension, diabetes and disruption of lipid homeostasis...

The renin-angiotensin system (RAS) is classically described as a hormonal system in which angiotensin II (Ang II) is one of the main active peptides. The action of circulating Ang II on its cognate Ang II type-1 receptor (AT1R) in circumventricular organs has important roles in regulating the autonomic nervous system, blood pressure (BP) and body fluid homeostasis, and has more recently been implicated in cardiovascular metabolism. The presence of a local or tissue RAS in various tissues, including the central nervous system (CNS), is well established...

Hypertension is one of the most well-established risk factors for atrial fibrillation. Long-standing untreated hypertension leads to structural remodeling and electrophysiologic alterations causing an atrial myopathy that forms a vulnerable substrate for the development and maintenance of atrial fibrillation. Hypertension-induced hemodynamic, inflammatory, hormonal, and autonomic changes all appear to be important contributing factors. Furthermore, hypertension is also associated with several atrial fibrillation-related comorbidities...

Blood pressure (BP) responses are controlled by various factors and understanding how BP changes is important to occupational health. This paper presents a review of the literature which reports BP responses in the firefighter population. Hypertension is one of the main risk factors underlying the pathophysiology of cardiovascular disease (CVD), and cardiac incidents remain the leading cause of line-of-duty deaths in firefighters. Risk factors for line-of-duty deaths include obesity, previous or underlying heart disease, and hypertension...

BACKGROUND: The target blood pressure has changed many times in the guidelines in past years. However, there is always a question; is it good to lower blood pressure below 120/80 or not? Control of blood pressure in hypertension is very important in reducing hypertension-modified organ damage. So, the guidelines recommend combining more than one antihypertensive drug to reach the target blood pressure goal. RESULTS: Combination therapy is recommended by guidelines to reach the blood pressure goal...

BACKGROUND: This review explores the mechanistic action of angiotensin-converting enzyme- 2 (ACE2) and transmembrane protease serine 2 (TMPRSS2) in the renin-angiotensinaldosterone system (RAAS) that predisposes hypertensive patients to the adverse outcome of severe COVID-19. METHODS AND RESULTS: Entry of SARS-CoV-2 into the host cell via ACE2 disrupts the RAAS system, creating an imbalance between ACE and ACE2, with an increased inflammatory response, leading to hypertension (HTN), pulmonary vasoconstriction and acute respiratory distress...

Cannabis sativa has chemically active compounds called cannabinoids, where Δ9- tetrahydrocannabinol (THC) and Cannabidiol (CBD) are the major ones responsible for the various pharmacological effects. The endocannabinoid system is an endogenous system considered a unique and widespread homeostatic physiological regulator. It is made up of type 1 (CB1) and type 2 (CB2) cannabinoid receptors. CBD, in turn, has a low affinity for CB1 and CB2 receptors, and regulates the effects arising from THC as a CB1 partial agonist, which are tachycardia, anxiety, and sedation...
