Abstract

Rheumatoid arthritis (RA) is a chronic systemic disease. The risk of cardiovascular morbidity and mortality is high in patients with RA. Heart rate turbulence (HRT) expresses ventriculophasic sinus arrhythmia and has been considered to reflect cardiac autonomic activity. It has been shown that HRT is an independent and powerful predictor of mortality. The aim of this study is to determine if HRT changes in patients with RA in comparison with the healthy controls. Methods: The study was performed as a cross-sectional study. Twenty-six patients with RA (mean age 56±10 years, 18 women) and 26 healthy controls (mean age 55±9 years, 18 women) were enrolled in this study. All participants underwent 24 hours Holter electrocardiogram monitoring. HRT measurements, turbulence onset (TO) and turbulence slope (TS), were calculated in patients and healthy controls that have at least one ventricular premature complex (VPC) in their Holter recordings. TO is a measure of the early sinus acceleration and TS is the measure of the rate of sinus deceleration that follows the sinus acceleration after a VPC. Mann-Whitney U test was used for comparison of continuous variables and the Chi-square test for comparison of categorical variables. Results: There were no statistically significant differences in TO and TS between the RA and control groups (TO: -2.2±3.1% vs -2.8±2.5%, p=0.25; TS: 11.5±9.7 ms/RR vs 15.5±10.9 ms/RR, p=0.10). Conclusion: HRT parameters, which determine the autonomic dysfunction, did not seem to be altered in patients with RA.(Anadolu Kardiyol 2011 1:11-5)

Özet

Romatoid artrit (RA), kronik sistemik bir hastalıktır. Bu hastalarda kardiyovasküler morbidite ve mortalite riski artmıştır. Kalp hızı türbülansı (KHT), ventrikülofazik sinüs aritmisinin bir sonucu olup, kardiyak otonomik aktivitenin bir göstergesi olarak kabul edilmektedir. Kalp hızı türbülansının (KHT), mortalitenin güçlü ve bağımsız bir belirteci olduğu gösterilmiştir. Çalışmanın amacı, RA'lı hastalardaki olası KHT değişikliklerini sağlıklı gönüllüler ile karşılaştırmaktır. Yöntemler: Çalışma, enine-kesitli bir çalışma olarak planlandı. Çalışmaya 26 RA hastası (ortalama yaş 56±10 yıl, 18 bayan) ve 26 sağlıklı kontrol grubu (ortalama yaş 55±9 yıl, 18 bayan) dahil edildi. Tüm katılımcılara 24 saat Holter elektrokardiyogram monitorizasyonu uygulandı. KHT parametreleri olan türbülans başlangıcı (TO) ve türbülans eğimi (TS), Holter kayıtlarında en az bir adet ventriküler erken vuru (VEV) olanlardan hesaplandı. TO, VEV sonrası oluşan erken sinüs hızlanmasının, TS ise, bu hızlanma sonrasında gelişen sinüs yavaşlamasının bir ölçüsüdür. İstatistiksel analizlerde, devamlı değişkenlerin karşılaştırılması için Mann-Whitney U testi ve kategorik değişkenlerin karşılaştırılması için Ki-kare testi kullanıldı. Bulgular: Her iki (RA ve kontrol) grup arasında, TO ve TS değerleri açısından anlamlı bir fark saptanmadı (TO: -2.2±3.1% karşın -2.8±2.5%, p=0.25; TS: 11.5±9.7 ms/RR karşın 15.5±10.9 ms/RR, p=0.10). Sonuç: Otonomik disfonksiyonun bir göstergesi olan KHT parametreleri RA hastalarında değişmemektedir.(Anadolu Kardiyol Derg 2011 1:11-5)
