Haemodynamic effects of nitrates, with special reference to the coronary circulation
Drugs
|January 1, 1987
Insights
This review discusses how nitrates affect coronary circulation and oxygen supply in angina. It highlights nitrates
Area of Science:
- Cardiovascular Physiology
- Pharmacology
Background:
- Angina pectoris results from an imbalance between myocardial oxygen supply and demand.
- Coronary circulation plays a critical role in regulating myocardial oxygen delivery.
- Nitrates are a cornerstone therapy for angina, but their precise mechanisms require ongoing elucidation.
Purpose of the Study:
- To review the pathophysiology of coronary circulation in the context of angina.
- To analyze the hemodynamic effects of nitrates on myocardial oxygen supply.
- To specifically examine the action of nitrates on coronary circulation.
Main Methods:
- Comprehensive literature review of studies on coronary pathophysiology, angina, and nitrate pharmacology.
- Analysis of hemodynamic data related to nitrate administration and coronary blood flow.
- Synthesis of existing knowledge to provide a cohesive overview.
Main Results:
- Nitrates exert significant effects on coronary circulation, influencing vasodilation and blood flow.
- These vascular actions directly impact myocardial oxygen supply, counteracting the ischemia in angina.
- Hemodynamic changes induced by nitrates contribute to the therapeutic benefits observed in angina patients.
Conclusions:
- Nitrates effectively improve myocardial oxygen supply by modulating coronary circulation.
- Understanding these mechanisms is crucial for optimizing anti-anginal therapy.
- Further research may refine the clinical application of nitrates based on their specific vascular actions.
Abstract:
The pathophysiology of coronary circulation and its effects on myocardial oxygen supply in angina are discussed and reviewed in relation to the haemodynamic effects of nitrates, with special reference to the action of nitrates on coronary circulation.

01:28Nitric Oxide Signaling Pathway
Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure to...
01:23Antihypertensive Drugs: Vasodilators
Vasodilators, primarily affecting the smooth muscles within arterial and venous walls, are commonly used for hypertension treatment. Medications such as minoxidil and hydralazine primarily target arteries and arterioles, while sodium nitroprusside acts on arterioles and venules. Minoxidil, functioning as a prodrug, is metabolized by hepatic sulfotransferase into its active form, minoxidil sulfate, after oral administration. This metabolite binds to the sulfonylurea receptor (SUR) component of...
01:29Pathophysiology of Cardiac Performance
Typical heart performance is influenced by heart rate, rhythm, myocardial contraction, and metabolism or blood flow. The cardiac muscle exhibits distinct electrophysiological features, including pacemaker activity and calcium channel control, which play a vital role in the heart's response to various drugs. The autonomic nervous system, comprising the sympathetic and parasympathetic branches, regulates heart rate. Sympathetic activation increases heart rate, while parasympathetic activation...
01:16Antianginal Drugs: Nitrates and β-Blockers
In cardiovascular health, antianginal drugs combat angina pectoris — a condition marked by chest pain owing to diminished blood flow to the heart.
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...

01:25Antianginal Drugs: Calcium Channel Blockers and Ranolazine
Angina pectoris, a primary symptom of ischemic heart disease, requires careful pharmacological interventions. In this context, calcium channel blockers (CCBs) and ranolazine have emerged as crucial pharmacotherapeutic agents, providing deep insights into the complexities of angina management.
CCBs, a diverse class that includes dihydropyridines (nifedipine) and diphenylalkylamines (verapamil and diltiazem), exert their effect by blocking calcium channels in cardiac and smooth muscle cells. This...

01:26Coronary Artery Disease II: Pathophysiology
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
