Hypertensive heart disease (HHD) encompasses a spectrum of abnormalities resulting from structural and functional adaptations to chronic pressure overload. The clinical manifestations of HHD range from asymptomatic left ventricular hypertrophy (LVH) to symptomatic heart failure. HHD has been associated with increased risk of cardiovascular morbidity and all cause mortality. However, regression of LVH by antihypertensive therapy has been associated with improved outcome. The pathogenesis of HHD involves various hemodynamic and nonhemodynamic factors including neurohormone, aldosterone. Aldosterone enhances myocardial fibrosis through its direct effect on mineralocorticoid and angiotensin II receptors leading to excessive collagen deposition within the myocardium. Increased myocardial fibrosis is a major determinant of hypertensive remodeling and the transition to heart failure. Aldosterone antagonists are effective antihypertensive agents. Additionally, they have been shown to improve LV structural remodeling, systolic and diastolic function in patients with HHD independent of its effect on blood pressure. Data on long-term benefit of these agents have thus far been limited to patients with advanced systolic heart failure and post-acute myocardial infarction LV systolic dysfunction. The potential benefit of aldosterone antagonists in patients with heart failure and preserved LV systolic function is currently being investigated in large scale clinical trials.
It is time to recognize that the quality, not quantity, of myocardium in hypertensive heart disease is responsible for adverse cardiovascular events. Experimental and clinical available data indicate that myocardial fibrosis due to the exaggerated accumulation of collagen type I and type III fibers predisposes to an enhanced risk of diastolic and/or systolic ventricular dysfunction, symptomatic heart failure, ischemic heart disease, and arrhythmia in patients with hypertensive heart disease. Thus, management of these patients must not only focus on detection and regression of left ventricular hypertrophy. Far more sensible are interventions aimed to detect and target hypertensive myocardial fibrosis. The available data on the use of biochemical and/or imaging methodologies to address excessive accumulation of collagen fibers in the myocardium of hypertensive patients are promising. On the other hand, preliminary data suggest that the goal of reducing myocardial fibrosis is achievable in patients with hypertensive heart disease treated with specific anti hypertensive agents. Collectively, these findings set the stage for larger trials where-in noninvasive measures and reparative strategies of myocardial fibrosis to prevent heart failure could prove useful.
World Heart Day is part of an international campaign to spread awareness about heart disease and stroke prevention. This is the perfect day to quit smoking, get exercising and start eating healthy – all in the name of keeping your ticker in good working order, and improving the health and well being of people the world over.
The World Heart Federation have found that heart disease and strokes are the world’s leading cause of death, killing 17.1 million people every year – that’s more than victims of cancer, HIV and AIDS and malaria.

The Emerging Sources Citation Index (ESCI) is a new index by Clarivate Analytics, extending the range of publications in Web of Science to include high-quality, peer-reviewed publications of regional importance and in emerging scientific fields. ESCI complements the highly selective indexes by providing earlier visibility for sources under evaluation as part of SCIE, SSCI, and AHCI’s rigorous journal selection process. Inclusion in ESCI provides greater discoverability which leads to increased citations.

Early vascular aging is a process associated with gradual alterations in the vessels, regarding their structure and function, taking a more rapid course than normal biological aging in the arteries. In the presence of cardiovascular disease, these age-associated alterations are accelerated, contributing in the appearance or the progression of cardiovascular disease, such as high blood pressure, dyslipidemia, smoking and diabetes. Endothelin-1 (ET-1) is the most abundant and important endothelin produced by vascular cells. ET-1 exerts its biological actions through the activation of two receptors: ETA and ETB. Many important functions are mediated by the activation of these receptors, such as cardiovascular remodeling, vasoconstriction, cell proliferation and differentiation, production of extracellular matrix, and water and sodium secretion control. ETA receptor seems to participate in the pathogenesis and development of diseases, such as diabetes, atherosclerosis, systemic and pulmonary hypertension, and cardiac remodeling after myocardial ischemia, whereas ETB receptor seems to prevent the overstimulation of ETA receptor, acting as a clearance receptor. Increased ET-1 system activity may contribute to vascular dysfunction in aging via multiple pathways, such as direct hemodynamic effects, vascular oxidative stress, inflammatory activity, mitogenic stimulation of the vascular smooth muscle cells and fibrotic processes. Endothelin receptor antagonists were considered to be used for the treatment of some diseases like hypertension, diabetes and chronic kidney disease. However, besides pulmonary hypertension, this class is not in clinical use because of the side effects and the availability of safer drugs for the treatment of these diseases.

Celebrating the World Heart Day on September 29th, we bring our focus to some serious problems related to the heart and vascular system that can lead a human being towards death. One such problem is the ageing of the blood vessels before their actual time. This phenomenon is called Early Vascular Ageing or EVA. Early vascular ageing is a significant marker for cardiovascular diseases and is generally identified by stiffening of the arteries.
EVA is caused when the blood vessels show signs of ageing before they reach their chronological age. This renders the blood vessels to be less flexible and disturbs the control of blood flow from and to the heart. It may occur due to various reasons including genetic factors, environmental effects on vascular system or any damages caused to the blood vessels over time etc. As the researchers, Dr. Stephane Laurent et al. notify in their article published in the journal, Current Hypertension Reviews, EVA is a problem that needs a lot of attention and finding its prevention can ensure many cardiovascular diseases can be combatted.
The article, Early Vascular Ageing (EVA): Definitions and Clinical Applicability, explains the phenomenon, its consequences and opportunities for finding preventive measures.
