COVID-19—The Pandemic of the 21st Century and Correlation With Cardiovascular System—A Single Center Experience

Objective: To analyze the data of the cardiac comorbidities, investigational modalities, laboratory parameters, and outcomes of patients with COVID-19 related to cardiovascular system hospitalized in our center.Methods: Confirmed cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) COVID-19 infection by positive result on polymerase chain reaction testing of a nasopharyngeal sample, who were admitted to Indraprastha Apollo Hospital, Delhi, were included in the study. Demographics, baseline comorbidities, and test results related to cardiovascular diseases were collected and analyzed.Results: The study included 1012 patients, admitted in our institute with a COVID-19 positive report. The mean age of the patients was 54.6 ± 6.8 years. The male to female ratio was 1.7:1. The demographic characteristics included diabetes in 38%, hypertensives 45%, history of coronary artery disease 22%, and chronic kidney disease 30%. A total of 426 patients were all treated on HCQS. A total of 7 patients were primigravida with full term pregnancy. The patients were also stratified according to age and demographic characteristics were noted. The total number deceased were 41 with 971 patients making complete recovery. The results showed no change in QTc interval in survivors and nonsurvivors. D-dimer, ferritin, and LDH were raised in all nonsurvivors compared to survivors. Even thrombocytopenia and low albumin levels were noted in nonsurvivors.Conclusions: The study revealed no significant change in QTc interval in survivors and nonsurvivors on HCQS. Critically ill patients showed the trends of being underweight, low albumin levels, thrombocytopenia, raised D-dimer, lactate dehydrogenase (LDH), and ferritin levels. Further studies on larger numbers are needed to confirm these findings.
