RESULTS OF THE REGIONAL PROJECT “KUZBASS WITHOUT ARRHYTHMIA”

Highlights

• For the first time in Kuzbass, a study was conducted to identify asymptomatic cardiac arrhythmias in the working-age population at the enterprise «AZOT». The study allowed for early diagnosis of arrhythmias requiring interventional treatment, reduced risks of complications, and ensured the return to work and a full life for patients with asymptomatic heart rhythm disorders.

Aim. To conduct a comprehensive examination to identify the prevalence of asymptomatic heart rhythm disorders requiring interventional treatment for tachyarrhythmia among the working-age population of AZOT LLC.

Methods. As part of the regional project «Kuzbass without arrhythmia» а total of 1,324 AZOT employees were examined, including 745 men (56.3%) and 578 women (43.7%), with an average age of 54 years. The first stage of the study included lectures on cardiovascular diseases for employees, while the second stage involved an assessment of their medical history and laboratory and instrumental examinations.

Results. The lecture course contributed to a 2.5–fold increase in employee motivation to complete the second stage of the examination. Atrial fibrillation and ventricular extrasystole (VES) were detected in 0.6% of ECG recordings and 0.4%, respectively. During 24-hour ECG monitoring, atrial fibrillation was detected in 1.8% of patients, ventricular extrasystoles in 4.8%, and supraventricular extrasystoles in 3.7%. Heart rhythm disturbances occurred in one in ten patients, with no symptoms or clinical manifestations, representing a 9.1% incidence. All patients with atrial fibrillation had indications for surgical treatment. Follow-up observation is recommended for supraventricular and ventricular extrasystoles.

Conclusion. Increased staff awareness facilitated the detection of arrhythmias and timely treatment.
