Characteristics of the Hospitalization Period in Patients Who Died as a Result of Covid-19 With Acute Cardiovascular Complications
The aim. To identify adverse risk factors in hospitalized patients with fatal consequences of the coronavirus disease-2019 and its acute cardiovascular complications. Materials and methods. A retrospective study was conducted of 66 people in the study group with acute respiratory failure and cardiovascular complications due to COVID-19. The comparison group was 48 people who died of acute cardiovascular events without SARS-CoV-2 infection or other bacterial or viral diseases. The criteria for inclusion in the study group were the presence of confirmed SARS-CoV-2 infection by the polymerase chain reaction method, the presence of acute cardiovascular complications during COVID-19, and patients hospitalized during its treatment. Inclusion criteria for the comparison group were hospitalized patients with acute cardiovascular diseases that led to death without SARS-CoV-2 infection. The exclusion criteria for both groups were: age before 18 years old; absence of informed consent of the authorized person of dead person or the decision of the authorized person to withdraw from the study at any of the stages; the presence of other co-infections that could have a cumulative negative effect on the state of the respiratory and cardiovascular systems (flu virus, hepatitis virus, human immunodeficiency virus, pathogens that led to symptoms of acute intestinal infections). Age and gender distribution, comorbidities, length of hospitalization, and laboratory markers were evaluated in both cohorts. Cardiovascular complications were confirmed by the results of ultrasound examinations, computed tomography angiography and comparison with postmortem morphological findings in autopsy reports for the analysis of the current study,. The results. There were 48 men (72.7%) and 18 women (27.3%) in the study group of 66 patients who developed cardiovascular complications at the background of COVID-19, and in the comparison group – 39 men (81.3%) and 9 women (18.7%), which indicates acceptable comparability of the groups among themselves due to sex (p=0.374) and age (p=0.338). In particular, the age median for men in the study group was 65 years (IQR - 21 years), with minimum and maximum age values – 36 and 83 years, respectively; the median age for women in the study group was also 65 years (IQR – 12.5 years), with the lower and upper age limits in the group being 41 and 78 years. The age median for men in the comparison group was 62 years (IQR 15 years), with a lower and upper age range of 54 and 81 years. The age median for women in the comparison group was 68 years (IQR – 16.5 years), with the lower and upper age values in the group being 55 and 79 years. Men and women of the comparison group did not statistically differ from each other in terms of age (р=0.412). A significant difference was found between the length of hospitalization in both cohorts (р˂0.00001) – the median length of stay in hospital for the study group was 15 days, and for the comparison group – 10 days. It was established that malignant diseases were an additional concomitant factor of mortality in the group of patients with COVID-19 (р=0.043). The percentage ratio of neutrophils (p=0.048) and lymphocytes (p=0.031) in patients of the study group significantly differed. Conclusions. Unfavorable risk factors in patients with fatal consequences of Coronavirus disease-2019 and acute cardiovascular complications were concomitant oncological pathology, a long period of hospitalization, and changes in the percentage ratio of neutrophils and lymphocytes.
