Abstract

Purpose: Leptin, a product of obesity gene and provides information about energy stocks of body to brain, is exclusively a kind of hormone in the form of protein, which affects hypothalamus. Leptin receptors are found in many different kind of tissues including heart muscle. Recently, several studies shown the relationship between leptin and heart failure. In our study, it has been aimed to study the relations between leptin level and Heart speed variability (HSV) parameters. Methods: According to New York Heart Association staging were classification a total 40 patients in 10s from 4 different phases were collected. The control group was containing 10 healty individuals. Time range parameters of HSV were obtained from the 24-hour holter data and it's relation with leptin levels was evaluated. Results: In the end of this study, it was observed that the leptin levels had decreased significantly in phase III and IV compared with I (in the order, p<0.05 and p<0.01). And also positive correlations between HSV parameters and leptin level were observed. Conclusion: Consequently, at the advanced phases of heart failure, leptin levels was decreased, and this was thought that it might be related with the increasing sympathetic activity.

Özet

Amaç: Vücudun enerji depolan ile ilgili bilgiyi beyne ulaştıran ve obesite geninin ürünü olan leptin hipotalamusu etkileyen protein yapıda bir hormondur. Leptin reseptörleri, aralarında kalp kası da bulunan birçok dokuda bulunmaktadır. Son zamanlarda leptinin kalp yetmezliği ile ilişkisini gösteren çeşitli çalışmalar yapılmıştır. Çalışmamızda serum leptin düzeyi ve kalp hızı değişkenliği (KHD) parametreleri ile olan ilişkilerinin incelenmesi amaçlanmıştır. Gereç ve Yöntem: Çalışmaya New York Heart Association sınıflamasına göre 4 farklı evreden 10'ar hasta olmak üzere toplam 40 hasta alınmıştır. Ayrıca bu hasta gruplarıyla karşılaştırmak amacıyla 10 adet sağlıklı bireyden oluşan kontrol grubu oluşturulmuştur. 24 saatlik holter kayıtlarından elde edilen KHD'nin zaman-alan parametreleri saptanmış ve leptin düzeyi ile olan ilişkileri değerlendirilmiştir. Bulgular: Leptin düzeylerinin evre III ve IV kalp yetmezliği gruplarında evre I'e göre anlamlı olarak (sırasıyla p<0.05 ve p<0.01) azaldığı saptanmıştır. Ayrıca KHD parametreleri ile leptin düzeyi arasında pozitif korelasyon gözlenmiştir. Sonuç: Kalp yetmezliğinin ileri evrelerinde serum leptin düzeyleri azalmış olup, bunun da artan sempatik aktivite ile ilişkili olabileceği düşünülmüştür.
