Hypertension or elevated arterial blood pressure (BP) is the most common cause of cardiovascular diseases (CVDs). The arterial BP is regulated by renin-angiotensin-aldosterone system (RAAS), whereas dysfunctional RAAS may lead to development of hypertension and associated CVDs. Parathyroid hormone (PTH) secreted by parathyroid glands regulates RAAS by directly stimulating aldosterone synthesis in zona glomerulosa cells, which leads to development of hypertension. Conversely, R...

Diabetes mellitus type 2 (DM-2) is a disorder characterized by high blood glucose levels in the context of insulin resistance and relative insulin deficiency. DM-2 is typically an outcome of combinations of hereditary elements of impaired insulin release and insulin resistance, and natural variables like obesity, overeating, absence of activity, aging and stress. A number of hormones, such as cortisol and growth (GH), have insulin-antagonistic effects. Cortisol is a predominan...

Diabetes mellitus type-II (DM-2) is a metabolic disorder characterized by high blood glucose levels due to insulin resistance and relative insulin deficiency. DM-2 often leads to hypertension, a prolonged condition of elevated blood pressure (BP). Both hypertension and diabetes have a pathological role in causing cardiovascular diseases (CVDs). While renin-angiotensin-aldosterone system (RAAS) regulates arterial BP, any pathology in RAAS system may lead to hypertension and rel...

Vitamin D plays a key role in the control of cardiovascular diseases (CVDs), acting as negative regulator of renin-angiotensin-aldosterone-system (RAAS), whereas calcium directly affects central blood pressure (BP) control center, nucleus tractus solitarus. We investigated associations between plasma concentrations of vitamin D and calcium and BP in 100 hypertensive CVDs patients and 100 normotensive subjects of 21–60 years. Vitamin D concentrations were measured using EC...
