Study of the vessels of the upper extremities and the rhythm of heart activity in patients with vibration disease in the post-СOVID period

Abstract

Currently, there are many consequences of the new coronavirus infection. We shall study the actual long-term consequences of this disease for population health in the coming years. It is necessary to consider concomitant chronic diseases in patients who are particularly dangerous in the post-COVID period. Vibration disease is one of the leading occupational pathologies in the Russian Federation. Symptoms of vibration disease are vegetative-vascular disorders, cold, cyanosis, paresthesia, violation of regional blood circulation of the extremities. As is known from numerous sources, the defeat of the cardiovascular system (CVS) against the background of COVID-19 infection occurs through angiotensin-converting enzyme (ACE-2) receptors, which presents in large numbers in the endothelium of veins and arteries. The study aims to research hemodynamics features in patients with vibration disease after a new coronavirus infection. In the clinic of occupational pathology, the researchers examined 28 patients with a previously established diagnosis of VD after a coronavirus infection. We did a Holter ECG, ultra-sound examination of the arteries and veins of the upper extremities. Arrhythmias in the form of supraventricular extrasystoles, paroxysms of atrial fibrillation, positional sinus tachycardia occur in patients with VB after a new coronavirus infection on an ECG and daily monitoring of the ECG by Holter. As is known, cardiac arrhythmias are essential in the development of acute and chronic vascular pathology, characterized by a decrease in arterial blood filling and changes. Ultrasound of the vessels of the upper extremities revealed moderate expansion of the radial and ulnar veins, insufficiency of the valve apparatus during functional tests, increased venous outflow. There was also an increase in the indicators of peripheral vascular resistance, which indicates violations of the tonic properties of the vessels of the upper extremities and violations of vasodilation. Scientists identified violations of the tonic properties of blood vessels in patients with vibration disease in the post-COVID period on ultrasound, arrhythmias in the form of supraventricular extrasys-toles, paroxysms of atrial fibrillation, positional sinus tachycardia on daily ECG monitoring.
