Dear readers,

Our journal is the official publication of Inonu University Medical Faculty and published uninterruptedly for 25 years. It was first published as the name of Inonu University Medical Journal and later as Journal of Turgut Ozal Medical Center. During its publication period, the journal accepted Turkish or English articles for publication.

Abstracting in an international index is just a paramount objective in the 25th year of the journal. Because of this goal, it was necessary to make a decision both in terms of journal name and publication language. It was important in this respect that the name of a general medical journal should be related to medicine again and it should be in English. For these reasons, the name of the journal was switched to Annals of Medical Research and its publication language is changed to in English. The logo of the journal was chosen as an apricot, which is the symbol of our city Malatya, the world capital of apricot. I hope the journal succeeds with its new name. Annals of Medical Research is published monthly.

Abstract

Aim: In patients with chronic total occlusion (CTO), negative cardiovascular outcomes (angina, more frequent ventricular arrhythmias, higher mortality) and reduced survival have been demonstrated. The association between several electrocardiogram (ECG) markers, revealing individuals at high risk for ventricular arrhythmia, and collateral has been investigated in different studies in coronary artery disease patients. In this study, we aimed to investigate the association between the electrocardiographic parameters between good coronary collateral group and poor coronary collateral group in CTO patients with PCI.
Material and Methods: Patients retrospectively implemented CTO PCI to those with symptomatic symptoms of myocardial ischemia or with the exact sign of ischemia in the CTO area. The patients were divided into 2 groups according to the Rentrop class: group 1 (Rentrop 0 and 1) and group 2 (Rentrop 2 and 3). Baseline characteristics, laboratory and ECGs, procedural data, and outcome data were retrospectively collected.
Results: In this study included 59 CTO patients undergoing PCI. Mean age was 61.0±10.3 years and 43 (72.9%) of patients were male, and PCI success was 69.4%. While 22 (37.2%) of the patients were poor collateral group 1 (Rentrop 0 and 1), the remaining 37 (62.3%) of them were good collateral group 2 (Rentrop 2 and 3). There was a significant difference, in poor and good collateral groups, QT dispersion (77.2±27.9 vs 66.5±22.5, p: 0.041, respectively), QTc dispersion (82.1±26.9 vs 70.4±23.9, p: 0.034, respectively), and the presence of fQRS (63.6% vs 43.2, p: 0.027, respectively). But there was no statistically difference in P wave dispersion (48.0±9.5 vs 47.2±11.3, p: 0.796). Correlation analysis reported the association between Rentrop classification and Syntax score (r: -0.397, p: 0.002), LDL-C (r: -0.198, p: 0.025), QT dispersion (r: -0.156, p: 0.045), QTc dispersion (r: -0.176, p: 0.037), and the presence of fQRS (r: 0.234, p: 0.021) were statistically significant.
Conclusion: We suggest that some ECG parameters are an important, easy, simple, and cost effective tool and can be beneficial in predicting the poor or good collateral in patients with CTO.

Keywords: Chronic total occlusion; fragmented QRS; P wave dispersion; Rentrop collateral; ventricular repolarization; QTc dispersion

Annals of Medical Research is the scientific official journal of the Inonu University Faculty of Medicine. It is published monthly. The essential aim of the Annals of Medical Research is to publish scientifically high quality clinical and experimental research articles on fields of medicine which can contribute to the literature data. In addition, review articles, case reports, editorials, letters to the editors and manuscripts on publication ethics and medical history, which can contribute to the education and practices of physicians and health sector professionals within the scope of the journal’s target audience and which can increase the level of scientific communication between the authors and readers, are included in the scope of the journal.
