#ischemia
- Acardiotrophy — Atrophy of the cardiac muscle or a lack of nutritional and structural development of the myocardium, caused by severe vascularization disorders (chronic ischemia), local metabolic deficiencies, or a lack of nervous and endocrine trophic stimulation. This phenomenon leads to the thinning of the heart walls, decrease in cardiac muscle mass, and a drastic reduction in the blood-pumping capacity of the body.
- Acrostealgia — A pathological clinical syndrome characterized by severe pain sensations localized strictly within the distal bony extremities of the body, particularly in the phalanges of the fingers and toes. This osteoarticular structural manifestation is driven by periosteal inflammatory processes, peripheral microvascular ischemic disorders, or advanced local neuro-trophic phenomena, often worsening upon exposure to cold temperatures or during fine movements.
- Induced ischemia — The act or process of inducing localized anemia or temporary ischemia; the controlled reduction or cessation of blood supply to a specific organ, tissue, or anatomical region during a surgical procedure. This structural technique is used to minimize bleeding in the operative field or to shrink a vascular structure.
- Angiopancreatitis — A severe inflammatory disease of the pancreas, characterized by the early, massive, and destructive involvement of its arterial and venous vascular network. This well-defined structural pathological process associates local vascular thrombosis, endothelial alteration, and secondary ischemic necrosis of the glandular parenchyma, clinically leading to an acute progression toward acute hemorrhagic or necrotizing-hemorrhagic pancreatitis.
- Angiostenosis — A pathological narrowing, either permanent or transient, of the lumen of a blood vessel (artery or vein) or a major lymphatic trunk. This structural phenomenon, most often caused by the deposition of atheromatous plaques, chronic inflammatory processes (vasculitis), or well-defined muscle spasms, significantly reduces circulating blood volume, causing ischemia in downstream tissues and requiring correction via angioplasty or bypass surgery.
- ANOCA — An international medical acronym used to describe myocardial ischemia with non-obstructive coronary arteries. This clinical syndrome manifests through chest pain (angina) and objective signs of ischemia, but angiographic investigations do not reveal major stenoses or mechanical blockages within the large epicardial coronary arteries, being driven instead by microvascular dysfunction or arterial spasms.
- Anti-ischemic — Preventing, combating, or alleviating ischemia (the reduction or cessation of blood circulation in a tissue or organ due to an arterial obstacle); a medication used in the treatment of ischemic heart disease or angina pectoris. In a clinical sense, it acts structurally by reducing myocardial oxygen consumption, dilating coronary vessels, and improving regional blood flow.
- Arteriospasm — A sudden, involuntary, and temporary constriction of the smooth muscle within the wall of an artery, causing an acute narrowing of the vascular lumen and a transient reduction in blood flow to the supplied tissue. This arterial spasm can be triggered by thermal stimuli (cold exposure), intense emotional stress, chemical substances, or nervous imbalances, generating episodes of reversible local ischemia (as seen in Raynaud's syndrome or vasospastic angina).
