Evaluation of Frontal QRS-T Angle in Patients with Coronary Artery Ectasia

Abstract

Background: Coronary artery ectasia (CAE) is defined by focal enlargement of the coronary artery exceeding 1.5 times the adjacent normal segment. CAE can often cause arrhythmias, heart failure, sudden death, and myocardial ischemia. Ischemia due to microvascular dysfunction may be responsible for the ventricular heterogeneity in CAE. Objectives: The aim of our study was to evaluate the frontal QRS-T angle in patients with CAE. Methods: Our study included 55 patients with CAE and 50 individuals in the control group. [...]
