During the COVID-19 pandemic, the relevance of the dynamics of the prevalence of cardiovascular disease (CVD) is increasing.

PURPOSE OF THE STUDY

To assess the association between the frequency of detection of a new coronavirus infection and the prevalence of CVD, taking into account cardiovascular comorbidity, the severity of COVID-19 and post-covid syndrome (PCS).

MATERIAL AND METHODS

In December 2021, 562 people were surveyed using Google Forms, of which 213 were men (37.9%); women — 349 (62.1%). There were 139 (24.7%) people under the age of 30; 30—44 years — 219 (39.0%), 45—59 years — 118 (21.0%) and 60 years and older — 86 (15.3%). The survey took into account gender, age, body mass index, risk factors for CVD, history of asymptomatic and symptomatic COVID-19, severity, presence of PCS and CVD.

RESULTS

According to the survey participants, 28.3% have CVD, 19.6% had asymptomatic COVID-19. The frequency of detection of asymptomatic COVID-19 did not depend on gender (men were 21.6%; women — 18.3%), age (21.6%; 21.0%; 19.5% and 12.8% in the corresponding age groups). groups) and the presence or absence of CVD (yes — 19.5%; no — 19.6%). 46.1% had a history of symptomatic COVID-19, the detection rate did not depend on gender (men were 46.0%; women — 46.1%), age (44.1%; 50.7%; 44.9% and 38.4% in the respective age groups) and the presence of CVD (yes — 47.2%; no — 45.7%). With a mild course of COVID-19, the presence of CVD was noted in 16.0% of respondents, moderate — in 27.4%, and severe — in 73.5%. In 41.4% of the respondents, PCS was observed (weakness — 59.6%, sleep disturbance — 47.7% and shortness of breath — 46.4%). PCS was detected more often in women (63.4%) than in men (50.0%). The severity of PCS increased with age (50.0%; 55.0%; 64.2% and 81.8% in the respective age groups), the severity of the disease (37.0%; 66.1% and 94.1%) and depended on the presence or absence of CVD (yes — 81.3%; no — 48.9%). PCS was more often detected in smokers (61.4%) and those prone to alcohol abuse (57.9%).

CONCLUSION

Against the background of cardiac comorbidity, every fifth study participant had asymptomatic and every second had symptomatic COVID-19. The frequency of detection of COVID-19 does not depend on gender, age, the presence or absence of cardiovascular diseases. The incidence of cardiovascular disease naturally increases with the severity of COVID-19. Post-covid syndrome was registered in 41.4% of those who had COVID-19, it developed more often in women, increased with age, severity of the disease, and depended on the presence or absence of cardiovascular diseases. The course of COVID-19 and the development of post-COVID syndrome were adversely affected by smoking and alcohol abuse.
