Nitrovasodilator. A nitrovasodilator is a pharmaceutical agent that causes vasodilation (widening of blood vessels) by donation of nitric oxide (NO), [1] and is mostly used for the treatment and prevention of angina pectoris. This group of drugs includes nitrates (esters of nitric acid), which are reduced to NO in the body, as well as some ...
Nitric oxide (nitrogen monoxide) is a molecule and chemical compound with chemical formula of N O. In mammals including humans, nitric oxide is a signaling molecule involved in several physiological and pathological processes. [1] It is a powerful vasodilator with a half-life of a few seconds in the blood.
Antianginal. An antianginal is a drug used in the treatment of angina pectoris, a symptom of ischaemic heart disease. Myocardial ischemia arises from the dysfunction of coronary macrovascular or microvascular components, leading to a compromised supply of oxygen and nutrients to the myocardium. The underlying pathophysiological mechanisms ...
In short, renal angina is a clinical guide that identifies patients at high-risk for AKI by integrating baseline, contextual, and clinical evidence of kidney injury. When criteria for fulfilling renal angina are met, an AKI biomarker (a renal troponin) is optimally used (Figure 1 - Renal Angina Thresholds). As the risk of AKI increases, less ...
The CCS grading system for angina is, in part, used to evaluate fitness to fly by the British Cardiovascular Society.They recommend no action by class I and II patients with stable angina, class III should consider mobility assistance from airport staff and in-flight supplemental oxygen therapy, and that class IV patients should ideally defer their travel plans or travel with a medical ...
Figure 1: The chemical structure of dichloroisoprenaline or dichloroisoproterenol (), abbreviated DCI — the first β-blocker to be developed. β adrenergic receptor antagonists (also called beta-blockers or β-blockers) were initially developed in the 1960s, for the treatment of angina pectoris but are now also used for hypertension, congestive heart failure and certain arrhythmias.

Variant angina. Variant angina, also known as Prinzmetal angina, vasospastic angina, angina inversa, coronary vessel spasm, or coronary artery vasospasm, [2] is a syndrome typically consisting of angina (cardiac chest pain). Variant angina differs from stable angina in that it commonly occurs in individuals who are at rest or even asleep ...
Nitroglycerin (medication) Nitroglycerin, also known as glyceryl trinitrate (GTN), is a vasodilator used for heart failure, high blood pressure (hypertension), anal fissures, painful periods, and to treat and prevent chest pain caused by decreased blood flow to the heart (angina) or due to the recreational use of cocaine. [1][2][3][4] This ...
