Key Result

The degree of coronary collateral circulation showed no significant relationship with the index of cardio-electrophysiological balance (iCEB) or Tp-e/QT ratio in patients with chronic total occlusion.

Study Design

Type

Observational (n=99)

Structured PICO

Is there a relationship between the degree of coronary collateral circulation and index of cardio-electrophysiological balance (iCEB) or Tp-e/QT ratio in patients with chronic total occlusion?

Population

99 individuals, comprising 44 patients with chronic total occlusion and 55 healthy controls, evaluated for electrocardiographic parameters.

Comparator

Healthy controls and comparison between good vs. poor collateral groups

Outcome

Index of cardio-electrophysiological balance (iCEB) and Tp-e/QT ratiosurrogate

The degree of coronary collateral circulation in patients with chronic total occlusion does not appear to significantly affect ventricular repolarization parameters such as iCEB and Tp-e/QT ratio.

Abstract

Amac: QT intervali / QRS suresi olarak hesaplanan kardiyak elektrofizyolojik denge indeksi (iCEB), malign ventrikuler aritmileri ongormek icin yeni bir gosterge olarak tanimlanmistir. Burada, koroner kollateral dolasim (KKD) derecesinin; iCEB ve Tp-e / QT orani ile iliskisini arastirmayi amacladik. Hastalar ve Yontem: Kronik total okluzyon (KTO) tanisi olan 44 hasta ile benzer yas ve cinsiyet dagiliminda 55 saglikli kisi calismaya alindi. KTO hastalari, iyi (n = 24) ve zayif (n = 20) kollateral grubu olarak siniflandirildi. Tum hastalarin 12-lead standart elektrokardiyogrami (EKG) kaydedildi ve Tp-e araligi, QT araligi, QRS suresi, Tp-e/QT orani ve QT/QRS oranlari olculdu. Bulgular: Ortalama Tp-e araligi ve Tp-e/QT orani gruplar arasinda benzerdi. Ayrica, gruplar arasinda iCEB veya iCEBc degerleri benzer izlendi. Alt grup analizinde, KKD derecesi ile Tp-e/QT orani, Tp-e suresi ve QT/QRS oranini iceren EKG parametreleri arasinda bir iliski saptanmadi. Sonuc: KTO'lu hastalarda iCEB ve Tp-e/QT orani ile KKD gelisiminin derecesi arasinda anlamli bir iliski saptanmadi.
