The role of vitamin D in the development of cardiac arrhythmias in locomotive drivers

Abstract

Introduction. Heart rhythm disorders in locomotive drivers are a significant disease that increases the risk of sudden death and thromboembolic complications, including during professional duties. Conditions associated with cardiac arrhythmias in locomotive drivers can create a state for disastrous situations on the railway. Identification of risk factors for heart rhythm disorders and their prevention in locomotive drivers is an important task. The study aimed to study the role of vitamin D in developing cardiac arrhythmias in locomotive drivers. Materials and methods. We recruited the patients in the cardiology department's conditions, JSC "Russian Railways" in Moscow. The study included patients with detected cardiac arrhythmias. We did not have patients with a history of surgical treatment of cardiac arrhythmias with organic myocardial diseases. Namely: ischemic heart disease, myocarditis, congenital and acquired heart defects, cardiomyopathy. Also, scientists did not study patients with somatic disorders, decompensation of chronic diseases, and endocrine and urinary systems. Results. The study revealed a widespread prevalence of low vitamin D levels among locomotive drivers with cardiac arrhythmias. The statistical analysis showed the effect of vitamin D deficiency on cardiac arrhythmias' development with a high risk of sudden death and thromboembolic complications. We revealed the negative impact of occupational stress on the development of cardiac arrhythmias in locomotive drivers. Scientists have found the relationship of vitamin D deficiency with the level of anxiety of drivers. A review of studies on the role of vitamin D deficiency in developing cardiovascular diseases, including cardiac arrhythmias, is presented. The results of the study are consistent with the data of the scientific literature. Conclusions. It is necessary to survey locomotive drivers to identify vitamin D deficiency with the subsequent correction to prevent cardiac arrhythmias.
