Abstract
In response to various stressors, cardiac chambers undergo structural remodeling. Long-term exposure of the right ventricle (RV) to pressure or volume overload leads to its maladaptive remodeling, associated with RV failure and increased mortality. While left ventricular adverse remodeling is well understood and therapeutic options are available or emerging, RV remodeling remains underexplored, and no specific therapies are currently available. Accumulating evidence implicates the role of mast cells in RV remodeling. Mast cells produce and release numerous inflammatory mediators, growth factors and proteases that can adversely affect cardiac cells, thus contributing to cardiac remodeling. Recent experimental findings suggest that mast cells might represent a potential therapeutic target. This review examines the role of mast cells in cardiac remodeling, with a specific focus on RV remodeling, and explores the potential efficacy of therapeutic interventions targeting mast cells to mitigate adverse RV remodeling.

Abstract
The role of histamine as a newly recognized sympathetic neurotransmitter has been presented previously, and its postsynaptic effects greatly depended on the activities of sympathetic nerves. Cardiac sympathetic nerves become overactivated under acute myocardial ischemic conditions and release neurotransmitters in large amounts, inducing ventricular arrhythmia. Therefore, it is proposed that cardiac sympathetic histamine, in addition to norepinephrine, may have a significant arrhythmogenic effect. To test this hypothesis, we observed the release of cardiac sympathetic histamine and associated ventricular arrhythmogenesis that was induced by acute ischemia in isolated mouse hearts. Mast cell-deficient mice (MCDM) and histidine decarboxylase knockout (HDC(-/-)) mice were used to exclude the potential involvement of mast cells. Electrical field stimulation and acute ischemia-reperfusion evoked chemical sympathectomy-sensitive histamine release from the hearts of both MCDM and wild-type (WT) mice but not from HDC(-/-) mice. The release of histamine from the hearts of MCDM and WT mice was associated with the development of acute ischemia-induced ventricular tachycardia and ventricular fibrillation. The incidence and duration of induced ventricular arrhythmias were found to decrease in the presence of the selective histamine H(2) receptor antagonist famotidine. Additionally, the released histamine facilitated the arrhythmogenic effect of simultaneously released norepinephrine. We conclude that, under acute ischemic conditions, cardiac sympathetic histamine released by overactive sympathetic nerve terminals plays a certain arrhythmogenic role via H(2) receptors. These findings provided novel insight into the pathophysiological roles of sympathetic histamine, which may be a new therapeutic target for acute ischemia-induced arrhythmias.

Abstract
1 Mast cells have classically been regarded as the 'bad guys' in the setting of acute myocardial ischaemia, where their released contents are believed to contribute both to tissue injury and electrical disturbances resulting from ischaemia. Recent evidence suggests, however, that if mast cell degranulation occurs in advance of ischaemia onset, this may be cardioprotective by virtue of the depletion of mast cell contents that can no longer act as instruments of injury when the tissue becomes ischaemic. 2 Many peptides, such as ET-1, adrenomedullin, relaxin and atrial natriuretic peptide, have been demonstrated to be cardioprotective when given prior to the onset of myocardial ischaemia, although their physiological functions are varied and the mechanisms of their cardioprotective actions appear to be diverse and often ill defined. However, one common denominator that is emerging is the ability of these peptides to modulate mast cell degranulation, raising the possibility that peptide-induced mast cell degranulation or stabilization may hold the key to a common mechanism of their cardioprotection. 3 The aim of this review was to consolidate the evidence implying that mast cell degranulation could play both a detrimental and protective role in myocardial ischaemia, depending upon when it occurs, and that this may underlie the cardioprotective effects of a range of diverse peptides that exerts physiological effects within the cardiovascular system.

Abstract
Several studies have examined the role of mast cells in the myocardial response to injury such as that caused by hypertension and ischemia-reperfusion. However, little is known about the influence of mast cells on normal myocardial structure and function. The present experiments examined cardiac function in Langendorff-perfused hearts isolated from 6- and 9-mo-old male mast cell-deficient ( Ws/ Ws) and mast cell-competent rats. A fluid-filled balloon catheter was used to measure left ventricular diastolic and systolic function at increasing preload volumes. At 6 mo of age, mast cell-deficient rats showed a slight cardiac hypertrophy (as monitored by heart weight and heart weight-to-body weight ratio) but no significant change in maximum observed systolic or diastolic function. In contrast, at 9 mo of age, the mast cell-deficient group showed no signs of hypertrophy but displayed a diastolic dysfunction characterized by decreased compliance without a significant decline in maximum observed basal −dP/d tmax. There were no significant differences in maximum observed values for measures of systolic function (developed pressure and +dP/d tmax). In summary, the results of this study in adult rats suggest that mast cells influence cardiac function in the absence of injury and that observed differences between mast cell-competent and -deficient animals vary with age. Thus it is important to consider these “physiological” actions and resulting changes in function when studying effects of insult in mast cell-deficient models.

Abstract
It has been proposed that the cardioprotective effects of myocardial ischaemic preconditioning may involve the release of mast cell mediators. The aim of the study was to determine whether mast cells are involved in the antiarrhythmic effect of ischaemic preconditioning in rat hearts. Preconditioning was achieved, both in anaesthetised rats and in rat isolated hearts, by a 3-min temporary occlusion of the left main coronary artery followed by 10 min of reperfusion before a 30-min permanent occlusion. Preconditioning had a marked antiarrhythmic effect, reducing the number of ventricular ectopic beats from 1,176 +/- 69 to 490 +/- 139 and the incidence of ventricular fibrillation from 40% to 0. Administration of the mast cell-stabilising drugs lodoxamide tromethamine and sodium cromoglycate (20 mg/kg/h i.v. 30 min before and throughout experimental protocol) did not modify the antiarrhythmic effect of preconditioning. Sodium cromoglycate, but not lodoxamide tromethamine, itself significantly reduced the number of ectopic beats that occurred over a 30-min period of ischaemia (from 760 +/- 181 to 153 +/- 33 in nonpreconditioned animals). Both drugs abolished the decrease in arterial blood pressure that occurred on coronary artery occlusion. The decrease in arterial blood pressure produced by the mast cell-degranulating compound 48/80 (50 microg/kg; i.v.) was attenuated to a similar degree by both drugs (decreases in pressure of 53 +/- 7, 31 +/- 1, and 25 +/- 3 mm Hg in control, sodium cromoglycate-treated, and lodoxamide tromethamine-treated animals, respectively). In rat isolated hearts, degranulation of mast cells with three consecutive doses of 50 microg of compound 48/80 had no antiarrhythmic effects and did not modify the antiarrhythmic effect of preconditioning. It is concluded that cardiac mast cells do not play a major role in the protection offered by ischaemic preconditioning on arrhythmogenesis in rat hearts.

Abstract
The cardiac distribution of mast cells was investigated after the induction of acute myocardial infarction in the rat. The left anterior descending coronary artery (LAD) was occluded by ligation in the infarct group, whereas in sham rats only a superficial ligature was placed beside the LAD. Rats of both groups were killed at 4, 7, 14, 21, 35, and 85 days following surgery. Hearts were excised and formalin-fixed. Mast cell densities were monitored in subepicardial and subendocardial layers of the left ventricle (LV) in 6 microns thick toluidine blue-stained cross-sections. In control (non-operated) animals, mast cell densities were comparable in the LV subepicardial and subendocardial layers (1.5-2.0 cells per mm2). Following infarction, the mast cell density at the subepicardial site of the infarction gradually increased, reaching a maximum of 25 cells per mm2 on day 21, while a non-significant increase was observed at the subendocardial site. In the non-infarcted regions, the mast cell density increased transiently to reach a maximum of 7 cells per mm2 on day 35 in the subepicardial layer. Again, changes in mast cell density in the subendocardial layer were non-significant. In the sham group, a gradual increase to 9 cells per mm2 on day 21 and a subsequent decrease to 5 cells per mm2 on day 85 were observed in the subepicardial layers. These findings indicate a massive accumulation of mast cells in the subepicardial layers of the infarcted region and a small but significant effect of the surgical procedure on cardiac mast cell deposition, especially in the outer layers of the left ventricle.

Abstract
We tested the hypothesis of anaphylaxis as a pathogenic factor in acute myocardial infarction. Mast cells were counted in the myocardium, coronary arteries and airways. Total serum IgE, mast cell tryptase, complements C3, C4, and factor B, were measured in 29 cases of sudden death from coronary artery thrombosis and in 27 controls. We found increased numbers of mast cells in the coronary arteries following coronary death: 46 +/- 21 (SD) compared with 22 +/- 10 (SD) in the control group (P < 0.002). In the myocardium and airways there were no differences between the groups. The concentrations of tryptase and IgE in serum did not differ between the groups although 20% of the coronary deaths had elevated values (> 200 kU/l) compared with 8% in the control group. Of the complement factors, C3 was higher in the coronary deaths (P < 0.05) than in the controls. The results give no evidence of anaphylactic reaction in the pathogenesis of acute myocardial infarction.

Abstract
Release of histamine (H) by ischemia-reperfusion injury was investigated in isolated rat hearts (Langendorff model). The effect of 10, 15, 20, 25, 30, 40 and 60 min ischemia (n = 10 each) on H in the coronary effluent and in cardiac tissue was studied after 4 min reperfusion. Release of creatine kinase and lactate dehydrogenase in the coronary effluent increased with time of ischemia. Tissue H increased from 95 +/- 10 ng/g rat heart (mean +/- SEM) before ischemia to max 148 +/- 10 ng/g after 20 min ischemia (p < 0.002), and increased also after 15 (p < 0.01), 25 (p < 0.01), and 30 min (p < 0.045). H in the coronary effluent increased after 15 (from 16 +/- 3 to 26 +/- 2 pmol/min, p < 0.044), 30 (26 +/- 6 pmol/min, p < 0.027), and 60 min ischemia (47 +/- 6 pmol/min, p < 0.0044). Release of H during ischemia-reperfusion is neither dependent on the severity of the ischemic insult, nor on the level of tissue H.

Abstract
The effects of graded doses of compound 48/80 on various cardiovascular and respiratory parameters were studied in pentobarbitone-anaesthetized rats. Following intravenous injections, this compound significantly depressed the mean blood pressure (MBP), left ventricular pressure (LVP) and dLVP/dtmax, and caused ventricular tachycardia (VT) or fibrillation (VF) and death. Heart rate (HR) response were variable, and there were no marked changes in airway resistance or blood gases. Pretreatment of the animals with either cimetidine or diphenhydramine significantly prolonged the time of onset of VT/VF but failed to alter the changes in other circulatory variables. A combination of cimetidine and diphenhydramine significantly alleviated the decreases in MBP and LVP and prevented the occurrence of VT/VF. It is suggested that the circulatory depression and the occurrence of ventricular arrhythmias following the administration of compound 48/80 result from activation of H1- and H2-receptors by elevated blood histamine levels due to release of the amine from tissues.
