Abstract:  This brief review considers some of the cardiac diseases and conditions where free radicals and related reactants are believed to be causative. The report also describes the beneficial actions of melatonin against oxidative cardiovascular disorders. Based on the data available, melatonin seems to have cardioprotective properties via its direct free radical scavenger and its indirect antioxidant activity. Melatonin efficiently interacts with various reactive oxygen and reactive… 
The role of melatonin in acute myocardial infarction.
TLDR
It is expected that melatonin administration could play a clinically relevant role in the pharmacotherapy of ischemic heart disease; an assumption supported by low toxicity and high safety of melatonin.
A Review of Biological and Pharmacological Actions of Melatonin: Oxidant and Prooxidant Properties
TLDR
Although melatonin could potentially be useful but safety, efficacy remains uncertain, the studies which document the influence of melatonin on the various oxidative stress associated diseases are reviewed.
A review of melatonin as a suitable antioxidant against myocardial ischemia–reperfusion injury and clinical heart diseases
TLDR
The information summarized in this review should serve as a comprehensive reference for the action of melatonin in cardioprotection and hopefully will contribute to the design of future experimental research.
Melatonin attenuates chemical-induced cardiotoxicity
TLDR
The therapeutic potential of melatonin in treatment of cardiotoxicities caused by various chemicals along with suggested molecular mechanisms of action for melatonin is reviewed.
Cardioprotective effects of melatonin: Focusing on its roles against diabetic cardiomyopathy.
Vascular endothelial cells and dysfunctions: role of melatonin.
TLDR
Melatonin administration has endothelium-protective potential in several pathological conditions, but it still needs to be established, whether melatonin is able to revert already established endothelial dysfunction in these conditions.
The Protective Effect of Melatonin on the Heart
TLDR
The potential of melatonin as a therapeutic agent for humans is strengthened by the finding that it ameliorates tissue damage in ischaemia/reperfusion in a number of organs.
Peripheral and Central Effects of Melatonin on Blood Pressure Regulation
TLDR
The increased level of serum melatonin observed in some types of hypertension may be a counter-regulatory adaptive mechanism against the sympathetic overstimulation, and could become regularly involved in the struggle against this widespread cardiovascular pathology.
Melatonin affords protection against myocardial ischemia-induced cerebral mitochondrial dysfunction: an in vivo study.
Background: Ischemic Heart Disease (IHD) is a health problem of global concern. The studies on myocardial ischemia induced changes in brain particularly cerebrum portion are scanty. Lacunae exist in

Melatonin: a novel protective agent against oxidative injury of the ischemic/reperfused heart.
Melatonin as an antioxidant: biochemical mechanisms and pathophysiological implications in humans.
TLDR
Melatonin's functions as an antioxidant include: a), direct free radical scavenging, b), stimulation of antioxidative enzymes, c), increasing the efficiency of mitochondrial oxidative phosphorylation and reducing electron leakage (thereby lowering free radical generation), and 3), augmenting the efficiencyof other antioxidants.
Pharmacological utility of melatonin in reducing oxidative cellular and molecular damage.
TLDR
The review summarizes some of the large amount of data documenting the ability of melatonin to limit molecular and organ damage in two situations, i.e. ischemia-reperfusion and ionizing radiation, where free radicals are generally conceded as being responsible for much of the resulting tissue destruction.
Beneficial effects of melatonin in protecting against cyclosporine A‐induced cardiotoxicity are receptor mediated
TLDR
Melatonin significantly reduces CsA cardiotoxicity, and the reduction in CsSA‐induced cardiot toxicity was mediated by the binding of melatonin to its membrane receptors.
Protective effect of melatonin against mitochondrial dysfunction associated with cardiac ischemiareperfusion: role of cardiolipin
TLDR
Protection of mitochondrial dysfunction was associated with an improvement of post‐ischemic hemodynamic function of the heart and this effect appears to be due, at least in part, to the preservation of cardiolipin molecules which play a pivotal role in mitochondrial bioenergetics.
Protective effects of melatonin on myocardial ischemia/reperfusion induced infarct size and oxidative changes.
TLDR
The results suggest that oxidative stress contributes to myocardial I/R injury and melatonin administration exerts a mitigating effect on infarct size and indicates that melatonin improves the antioxidant capacity of the heart and attenuates the degree of lipid peroxidation after I/ R.
Melatonin protects against myocardial doxorubicin toxicity in rats: role of physiological concentrations
TLDR
Physiological and pharmacological effects of melatonin on Dox‐induced changes in the levels of malondialdehyde (MDA), a lipid peroxidation product, and morphological changes in heart strongly suggest that both physiological and Pharmacological concentrations ofmelatonin are important in protecting the heart from Dox-induced damage in rats.
Effect of melatonin and metabolites on copper-mediated oxidation of flow density lipoprotein.
TLDR
The present results indicate that the pineal hormone melatonin appears to have little antiatherogenic property as regards the oxidation of LDL, however, its main breakdown product 6-hydroxymelatonin inhibits LDL-oxidation comparable to vitamin E.
A proposed mechanism to explain the stimulatory effect of melatonin on antioxidative enzymes
TLDR
It is proposed that melatonin modulates antioxidant enzyme activities via its interaction with calmodulin, which in turn inhibits downstream processes that lead to the inactivation of nuclear RORα melatonin receptor, which downregulates NF‐κB‐induced antioxidant enzyme expression.
Protective effects of melatonin on myocardial ischemia/reperfusion injury in vivo
TLDR
Melatonin suppresses ischemia‐ and reperfusion‐induced ventricular arrhythmias and reduces infarct size resulting from I/R injury and the pronounced cardioprotective activity of melatonin may be mediated by its antioxidant activity and by its capacity for neutrophil inhibition in myocardial I/ R.
