Evaluation of Platelet Indices in Diabetic Patients with Myocardial Bridges

Abstract

Objectives: Myocardial bridges (MB) are a congenital anomaly in which part of the epicardial coronary artery is intramuscular, known as the presence of myocardium, which causes narrowing of the artery during heart contraction. We aimed to evaluate hemogram parameters (especially platelet indices) in diabetic patients with myocardial bridges. Methods: We reviewed angiograms performed between May 2017 and August 2019 at Bolu Abant Izzet Baysal University Medical Faculty Hospital. After appropriate exclusions, diabetic patients were divided into groups with myocardial bridges and normal coronary artery groups. A total of 124 patients were included in the study and hemogram parameters of these two groups were compared. Kolmogorov Smirnov test was used to examine the normality of variables. Data were compared using univariate tests including independent samples t-test, Mann–Whitney U-test and chi-square test. Results: Compared to control group PDW (17.7 (15.9-19.5) vs.17.4 (16.2-18.9) % p=0.047), MPV (8.3 (6.6-11.4) vs. 7.5 (6.6-8.7) Fl p<0.001), PCT (0.2 (0.16-0.25) vs. 0.18 (0.13-0.24) p=0.004), and Neutrophil-Lymphocyte Ratio (NLR) (1.71 (0.82-9.14) vs. 1.43 (0.78-5.75) p=0.036) were significantly higher in MB patients. There was no significant difference between the two groups in terms of other biochemical and hemogram values. Conclusion: Common, simple and inexpensive platelet indices were found to be increased in myocardial bridge diabetic patients
