Abstract

Aim: Early repolarization (ER) is a frequent indication, and it is important to correctly evaluate the effects of its benign and malignant forms in terms of prognosis. It was aimed to compare ER cases with the normal population in terms of multi-vessel disease, bypass and mortality.
Material and Method: This study comprised 776 patients aged 18 and older who admitted the emergency department between January 2015 and December 2020. 377 of these patients had ER in the electrocardiogram (ECG), 409 patients had normal ECGs and were added to the study as the control group. Age, gender, multi-vessel disease, by-pass and mortality relations of the patients were evaluated with angiographic findings.
Results: The mean age of 786 patients was 50.49±6.82 years, 372 (47.3%) were female, and the age range was 23-66 years (p<0.001). Of the cases, 110 (14%) were in the horizontal ER, 267 (34%) were in the ascending ER, and 409 (52%) were in the normal group. Multi-vessel disease was observed in 58 (7.4%) of all cases (p<0.001), while 19 (2.4%) had a by-pass attempt because angiography could not be cured (p=0.001). Of the cases with early repolarization, 176 (22.4%) were inferior, 112 (14.2%) were inferolateral, 77 (9.8%) were anterior, and a small number of them were 12 (1.5%) common ER types (p<0.001). Angiography was normal in 575 (73.2%) cases, left anterior descending artery was occluded in 65 (8.3%), circumflex artery was occluded in 73 (9.3%) and right coronary artery was occluded in 73 (9.3%) cases (p<0.001). Eighteen (2.3%) patients resulted in mortality in the 60-month follow-up of all cases. Of these, 9 (8.2%) were horizontal, 2 (0.7%) were asending, and 7 (1.7%) were in the normal population (p<0.001).
Conclusion: Electrocardiography can be a helpful method to evaluate interventional angiography, prognosis and mortality in both early repolarization cases and normal cases.
