ABSTRACT
Background: COVID-19 tends to have a harsher course in the elderly population, which can include the development of arrhythmias, including supraventricular tachycardia (SVT). Due to lack of sufficient data, we studied baseline patient characteristics, comorbidities, and outcomes of SVT in octogenarians admitted with COVID-19, using the 2020 National Inpatient Sample (NIS). Objective(s): We aimed to study the patient characteristics and outcomes of SVT in octogenarians admitted with COVID-19, using the 2020 National Inpatient Sample (NIS). Method(s): Octogenarians (ages 80-89 years, inclusive) with COVID-19 were recruited from the 2020 NIS (April 1st 2020 - December 31st 2020). A diagnosis of SVT was identified via the ICD-10 code "I47. 1". Patient characteristics that can influence the presence of SVT were identified via logistic regression models. The adjusted odds ratios (aOR) having cardiogenic shock or mortality among COVID-19 positive octogenarians with SVT were also explored. Result(s): Our study consisted of 240570 octogenarians who tested positive for COVID-19. 2.2% of them (5250 cases) also had a diagnosis of SVT during their hospitalization. Among them, Females (aOR 0.919, 95%CI 0.868-0.973, p<0.01) were more likely to develop SVT. Racial disparities were also observed as Blacks (aOR 1.234, 95%CI 1.137-1.338, p<0.01) had higher odds of having SVT, whereas Hispanics (aOR 0.898, 95%CI 0.819-0.984, p=0.021) had lower odds compared to Whites. Comorbidities such as chronic pulmonary disease (aOR 1.106, 95%CI 1.037-1.179, p<0.01), and heart failure (aOR 1.122, 95%CI 1.053-1.195, p<0.01) also led to higher odds of SVT. Lower odds were seen among those with diabetes (aOR 0.852, 95%CI 0.802-0.905, p<0.01), obesity (aOR 0.839, 95%CI 0.764-0.921, p<0.01), or smoking history (aOR 0.892, 95%CI 0.835-0.954, p<0.01). The use of mechanical ventilation (aOR 2.829, 95%CI 2.638-3.034, p<0.01) or non-invasive ventilation (aOR 1.755, 95%CI 1.615-1.907, p<0.01) showed higher odds of developing SVT. Finally, patients with SVT had increased risk of cardiogenic shock (aOR 1.510, 95%CI 1.206-1.891, p<0.01) and mortality (aOR 1.166, 95%CI 1.085-1.253, p<0.01). Conclusion(s): Multiple factors influenced the presence of SVT among octogenarians who had COVID-19. SVT in these patients was associated with higher incidences of cardiogenic shock and mortality. Additional focus targeting patient care and further research to better understand the mechanisms behind these variations may help improve outcomes. [Formula presented]Copyright © 2023
ABSTRACT
Background: Viruses are the most common cause of myocarditis. With the ongoing COVID-19 pandemic, several cases of myocarditis have been reported in COVID-19 positive patients. Such patients may also experience a variety of arrhythmias that can provoke death. Objective(s): To evaluate the presence of various cardiac arrhythmias among COVID-19 positive myocarditis patients and understand their impact on mortality. Method(s): COVID-19 positive patients, admitted between April 1st 2020 to December 31st 2020, were recruited from the 2020 National Inpatient Sample. The presence of myocarditis and various cardiac arrhythmias were also identified via their respective ICD-10 codes. Logistic regression models were used to identify the odds of mortality in the presence of myocarditis. We further proceeded to estimate the odds of mortality among myocarditis patients who had various arrhythmias. Result(s): Our study found 6135 (0.4%) patients with myocarditis among 1628110 cases of COVID-19 recorded in the United States between April to December 2020. Age ranged between 0 - 90 years with a mean of 58 years. Multiple cardiac arrhythmias were also observed among myocarditis patients as 310 (5.1%) recorded supraventricular tachycardia, 520 (8.5%) had ventricular tachycardia, 120 (2.0%) had ventricular fibrillation, 520 (8.5%) had paroxysmal atrial fibrillation, 165 (2.7%) had atrial flutter, and 20 (0.3%) had long QT syndrome. The presence of myocarditis was linked with higher odds of mortality among all COVID-19 patients (aOR 2.551, 95% CI 2.405-2.706, p<0.01). Various cardiac arrhythmias were also potential predictors of mortality among myocarditis cases in COVID-19 patients, such as supraventricular tachycardia (aOR 1.346, 95% CI 1.041-1.74, p=0.023), ventricular tachycardia (aOR 1.896, 95% CI 1.557-2.308, p<0.01), ventricular fibrillation (aOR 4.161, 95% CI 2.74-6.319, p<0.01), and atrial flutter (aOR 1.485, 95% CI 1.047-2.106, p=0.026). Conclusion(s): Myocarditis was associated with higher mortality among COVID-19 admissions. Arrhythmias such as supraventricular tachycardia, ventricular tachycardia, ventricular fibrillation, and atrial flutter were predictive of higher mortality in these patients. Continued caution is advised among health-care providers encountering these arrhythmias in myocarditis patients who are COVID-19 positive.
