Special Issue Information

Dear Colleagues,

Hypertension, defined as elevated blood pressure, if the systolic blood pressure is more than 140 mmHg, and or the diastolic blood pressure is higher than 90 mmHg, measured on two different days. Hypertension represents a medical condition that increases significantly risk for cardiovascular, cerebrovascular, and chronic kidney diseases. Besides, it is considered a leading cause of mortality and morbidity worldwide.

The mechanisms underlying the pathological processes of hypertension are not completely clarified. However, relevant evidence correlates the increase of oxidative stress with the development of hypertension. Results of preclinical and clinical studies have demonstrated the crucial role of oxidants compounds and oxidative phenomena in the progression of hypertension. In particular, oxidative stress due to hypertension is associated with endothelial dysfunction in the vessels. Based on World Health Organization guidelines, adults with hypertension requiring treatment from any of three classes of antihypertensive drugs such as thiazide, and thiazide-like agents, angiotensin-converting enzyme inhibitors, or angiotensin-receptor blockers, and long-acting dihydropyridine calcium channel blockers. Since reactive oxygen species are a primary trigger of hypertension, antioxidant therapy would have a favorable effect on hypertension's consequences. In particular, the reduction of oxidative stress could represent a strategy to prevent cardiovascular events in hypertensive patients.

The main goal of this special issue is to highlight different aspects of the involvement of oxidative stress in the development of hypertension, and correlated end-organ damage processes. The special issue will be focused on the mechanisms that would explain this correlation. This issue, therefore, can include publishing preclinical and clinical reports or reviews relating to any of the following topics: hypertension, reactive oxygen species production, oxidative stress, endothelial dysfunction, neurodegeneration, antihypertensive drugs, and their role as antioxidants, antioxidant treatment, or antioxidant supplementation.

We look forward to your contribution.

As in other fields, chronotherapy applied to arterial hypertension (AHT) may have implications on oxidative stress. We compared the levels of some redox markers between hypertensive patients with morning and bedtime use of renin-angiotensin-aldosterone system (RAAS) blockers. This was an observational study that included patients older than 18 years with a diagnosis of essential AHT. Blood pressure (BP) figures were measured using twenty-four-hour ambulatory BP monitoring (24-h ABPM). Lipid peroxidation and protein oxidation were assessed using the thiobarbituric acid reactive substances (TBARS) and reduced thiols assays. We recruited 70 patients with a median age of 54 years, of whom 38 (54%) were women. In hypertensive patients with bedtime use of RAAS blockers, reduced thiol levels showed a positive correlation with nocturnal diastolic BP decrease. TBARS levels were associated with bedtime use of RAAS blockers in dipper and non-dipper hypertensive patients. In non-dipper patients, bedtime use of RAAS blockers was also associated with a decrease in nocturnal diastolic BP. Chronotherapy applied to bedtime use of some BP-lowering drugs in hypertensive patients may be linked to a better redox profile. Full article

Hypertension remains the leading cause of disease burden worldwide. Hypertension can originate in the early stages of life. A growing body of evidence suggests that oxidative stress, which is characterized as a reactive oxygen species (ROS)/nitric oxide (NO) disequilibrium, has a pivotal role in the hypertension of developmental origins. Results from animal studies support the idea that early-life oxidative stress causes developmental programming in prime blood pressure (BP)-controlled organs such as the brain, kidneys, heart, and blood vessels, leading to hypertension in adult offspring. Conversely, perinatal use of antioxidants can counteract oxidative stress and therefore lower BP. This review discusses the interaction between oxidative stress and developmental programming in hypertension. It will also discuss evidence from animal models, how oxidative stress connects with other core mechanisms, and the potential of antioxidant therapy as a novel preventive strategy to prevent the hypertension of developmental origins.
