Abstract:

Rhythm disorders in young people are often reported and when they are persistent, repetitive or with a severity degree, an ethiopathgenical assessment of arrhythmogenic risk factors and their implications is required. Purpose: Arrhythmogenic risk factors evaluation and the possibility of determining oxidative stress in the arrhythmic pathology in young people. Material and Methods: The study was conducted on 184 young subjects, aged 16-26 years old; the points of interest were: the presence or absence of cardiac dysrhythmias, the existence of proarrhythmogenic risk factors and determination of oxidative stress status modifications. Results: Of the studied young subjects, 39% presented heart rhythm disturbances, repetitive or persistent (atrial extrasystolic arrhythmia, sinus tachycardia, ventricular extrasystolic arrhythmia, paroxysmal atrial fibrillation, paroxysmal supraventricular tachycardia, associated dysrhythmias, atrial flutter, sinus bradycardia), which have been associated with the following risk factors: coffee consumption 82%, stress 80%, physical effort 72%, energy drinks consumption 72%, hyperlipidic diet 69%, familial predisposition 69%, alcohol intake 53%, frequent sleep deprivation 50%, smoking 31%, overweight 31%. The observed risk factors may be involved in the increasing of oxidative stress level, and, for this reason, the determination of oxidative stress biomarkers is required. The association of arrhythmogenic risk factors, with the expression of oxidative stress markers and the existence of enzymatic genetic polymorphism of redox systems, requires proper monitoring for the further risk of endothelial lesions induction, leading to aterosclerosis. Conclusions: Arrhythmogenic risk factors and biomarkers of oxidative stress are important, especially in young people cases, for monitoring the cardiovascular risk, for primary prevention and early treatment.
