The role of histamine in the cardiovascular system
1Henri Beaufour Institute, Le Plessis-Robinson, France.
Insights
Histamine, acting via H1 and H2 receptors, influences the cardiovascular system, affecting calcium and catecholamines. While its role in myocardial damage and arrhythmias is suggested, its precise involvement in early cardiovascular diseases needs more research.
Area of Science:
- Cardiovascular Physiology
- Pharmacology
Background:
- Histamine plays a role in cardiovascular regulation.
- Its actions are mediated through H1 and H2 receptors.
- Similarities exist between adrenergic and histaminergic systems.
Purpose of the Study:
- To review the role of histamine in the cardiovascular system.
- To explore histamine's actions on calcium and catecholamines.
- To discuss histamine's potential involvement in cardiovascular diseases.
Main Methods:
- Literature review of studies on histamine and the cardiovascular system.
- Analysis of histamine's effects on calcium and catecholamine pathways.
- Examination of evidence linking histamine to myocardial damage and arrhythmias.
Main Results:
- Histamine, via H1 and H2 receptors, impacts cardiovascular function.
- Evidence suggests histamine's involvement in myocardial damage and arrhythmias.
- The precise role of histamine in early cardiovascular disease stages remains unclear.
Conclusions:
- Histamine's cardiovascular effects are mediated by H1 and H2 receptors.
- Further investigation is required to elucidate histamine's exact role in myocardial ischemia and atherosclerosis.
Abstract:
This article reviews briefly the role of histamine through its H1 and H2 receptors on the cardiovascular system and its action on calcium and catecholamines. The analogy between the adrenergic and the histaminergic systems is well demonstrated and there is evidence that histamine participates in myocardial damage and arrythmias, but the question of its exact role in the early stages of cardiovascular diseases, such as myocardial ischaemia and atherosclerosis, requires further study.
