#hypertension

• Aldosteronism — An endocrine clinical condition caused by the excessive, pathological secretion of the mineralocorticoid hormone aldosterone by the adrenal cortex. This metabolic disruption triggers massive sodium and water retention in the body, coupled with exaggerated potassium elimination, manifesting primarily as severe hypertension, chronic muscle weakness, and spasms.
• Antiadrenergic — Blocking, inhibiting, or diminishing the effects of adrenaline and noradrenaline on adrenergic receptors within the sympathetic nervous system. In medical practice, it refers to a class of medications (sympatholytics), such as alpha-blockers and beta-blockers, used to treat hypertension and cardiac arrhythmias.
• Antirenin — A specific antibody that neutralizes renin (an enzyme secreted by the kidneys with a major role in regulating blood pressure through the renin-angiotensin-aldosterone system). In biomedical research and pharmacology, the substance is used as an experimental or immunological tool to block excessive renin enzymatic activity, helping to study the mechanisms of renal hypertension.
• Arteriosclerosis — A chronic, degenerative vascular condition characterized by the thickening, stiffening, and loss of elasticity of arterial walls, a process often correlated with aging or mineral deposition within the tunica media of the vessels. This umbrella term encompasses atherosclerosis (lipid plaque formation in the endothelium) and Mönckeberg's arteriosclerosis (medial calcification), leading to reduced vascular compliance, elevated systolic pressure, and impaired blood flow to vital organs.
