Ventricular histamine concentrations and mast cell counts in the rat heart during acute ischaemia

Agents and Actions

Abstract

The ventricular histamine concentrations and mast cell counts of naive and disodium cromoglycate-treated rats subjected to acute left coronary artery ligation under pentobarbitone anaesthesia were examined. In naive animals, there was a significant increase in the right ventricular histamine level at 2 min following left coronary artery ligation. Left ventricular histamine concentrations tended to decrease, and were significantly lower than those of the right ventricle at 5 min. However there were no significant changes in mast cell counts of the right or left ventricles after left coronary artery ligation. Treatment with disodium cromoglycate did not significantly alter the ventricular mast cell counts, interfere with the changes in ventricular histamine concentrations, or the occurrence of early ventricular arrhythmias and haemodynamic changes in response to acute left coronary artery ligation. It is suggested that the increase in the right and decrease in the left ventricular histamine concentrations during acute myocardial ischaemia involves mainly the non-mast cell stores, instead of mast cell sources, of cardiac histamine.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
