Kardiyak Yeniden Şekillenme ile Kardiyo-Elektrofizyolojik Denge İndeksi Arasındaki İlişki

Abstract

Objective: Pathophysiological changes in response to myocardial infarction (MI) result in cardiac remodeling. Left untreated this pathologic process contributes to impairment of ventricular function and development of malignant ventricular arrhythmias. Recently introduced ECG‐based marker index of cardio‐electrophysiological balance (iCEB) has been shown to be associated with various cardiac conditions. Herein, we aimed to investigate the association between the iCEB and cardiac remodeling in post-MI patients. Material and Methods: Patients aged ≥18 years presenting with acute MI who underwent successful percutaneous coronary intervention between January 2020 and January 2021 were recruited. Regarding the assessment of cardiac remodeling, left ventricular (LV) mass, LV mass index (LVMI), and relative wall thickness (RWT) were measured before the start of treatment and six months after the procedure along with the QT/QRS ratio (iCEB), and QTC/QRS ratio (iCEBc). Results: According to our study, estimated QT/QRS (iECB) and QTc/QRS (iECBc) ratios were found to be significantly lower at six-month follow-up compared to baseline values (4.73∓0.60 vs 4.62∓0.55 & 4.93∓0.59 vs 4.78∓0.55, p
