Abstract

It is believed that myocardial ischemia-reperfusion injury is related to increased free radical generated and intracellular calcium overload especially during the period of reperfusion. The pineal secretory product, melatonin, is known to be a potent free radical scavenger, antioxidant and can inhibit the intracellular calcium overload. In this review, we have summarized the fundamental of cardiac ischemia-reperfusion injury and the effects of melatonin on myocardial damage that related to cardiac ischemia-reperfusion injury. The total antioxidant capacity of human serum is related to melatonin levels. Incidence of sudden cardiac death is high in the morning hours. It has been shown that melatonin levels are significantly low at these times and patients with coronary heart disease have lower than normal individuals. These findings thought that melatonin would be valuable to test in clinical trials for prevention of possible ischemia-reperfusion-induced injury, especially life threatening arrhythmias and infarct size, effecting life quality, associated with thrombolysis, angioplasty, coronary artery spasm or coronary bypass surgery.

Özet

Miyokardiyal iskemi-reperfüzyon hasarının özellikle reperfüzyon periyodu sırasında artmış serbest radikal üretimi ve hücre içi aşırı kalsiyum yüklenmesi ile ilişkili olduğuna inanılmaktadır. Pineal bezden salgılanan hormon olan melatonin, güçlü bir serbest radikal yakalayıcı ve antioksidan olarak bilinir ve hücre içi aşırı kalsiyum yüklenmesini inhibe edebilir. Bu derlemede, miyokardiyal iskemi-reperfüzyon hasarının temelini ve melatoninin iskemi-reperfüzyon ile ilişkili miyokardiyal hasar üzerindeki etkilerini özetledik. İnsan total antioksidan kapasitesi serum melatonin düzeyi ile ilişkilidir. Ani kardiyak ölüm insidansı sabah saatlerinde yüksektir ve bu saatlerde melatonin düzeyi anlamlı bir şekilde düşüktür. Koroner kalp hastalığı olanlarda normal bireylere göre melatonin düzeyi azalmıştır. Bu bulgular; melatoninin iskemik kalp hastalıklarının önlenmesi ve tedavisinde, baypas, koroner arter spazmı, anjiyoplasti ve trombolitik süreçler sonrası gelişen reperfüzyon hasarının ve özellikle de hayatı tehdit eder nitelikteki aritmilerin ve ileriki yaşam kalitesini etkileyebilen infarkt alanının önlenmesi gibi durumlarda klinik olarak test edilebileceğini düşündürmektedir.
