Nationwide Analysis of Cardiac Arrest Outcomes During the COVID-19 Pandemic.

The coronavirus disease 2019 (COVID-19) pandemic had a significant impact on the chain of survival following cardiac arrest. However, large population-based reports of COVID-19 in patients hospitalized after cardiac arrest are limited. The National Inpatient Sample database was queried for cardiac arrest admissions during 2020 in the United States. Propensity score matching was used to match patients with and without concurrent COVID-19 according to age, race, sex, and comorbidities. Multivariate logistic regression analysis was used to identify predictors of mortality. A weighted total of 267,845 hospitalizations for cardiac arrest were identified, among which 44,105 patients (16.5%) had a concomitant diagnosis of COVID-19. After propensity matching, cardiac arrest patients with concomitant COVID-19 had higher rate of acute kidney injury requiring dialysis (64.9% vs 54.8%) mechanical ventilation >24 hours (53.6% vs 44.6%) and sepsis (59.4% vs 40.4%) compared to cardiac arrest patients without COVID-19. In contrast, cardiac arrest patients with COVID-19 had lower rates of cardiogenic shock (3.2% vs 5.4%, P < 0.001), ventricular tachycardia (9.6% vs 11.7%, P < 0.001), and ventricular fibrillation (6.7% vs 10.8%, P < 0.001), and a lower utilization of cardiac procedures. In-hospital mortality was higher in patients with COVID-19 (86.9% vs 65.5%, P < 0.001) and, on multivariate analysis, a diagnosis of COVID-19 was an independent predictor of mortality. Among patients hospitalized following a cardiac arrest during 2020, concomitant COVID-19 infection was associated with significantly worse outcomes characterized by an increased risk of sepsis, pulmonary and renal dysfunction, and death.

A Comparison of COVID-19 and Influenza-Associated Myocarditis: A Nationwide Study in the United States.

We aimed to compare the characteristics and outcomes of adult patients hospitalized with myocarditis and either concomitant corona virus disease 2019 (COVID-19) or influenza, and elucidate clinical predictors associated with adverse outcomes in both groups. The study used the national inpatient sample (NIS) from 2019 to 2020 to identify 27,725 adult myocarditis hospitalizations, of which 5840 had concomitant COVID-19 and 1045 had concomitant influenza. After propensity score matching, the in-hospital mortality from myocarditis was significantly higher in COVID-19 compared to influenza. Patients with myocarditis and COVID-19 were more likely to have cardiovascular comorbidities and be older than those with influenza-associated myocarditis. Predictors of mortality were also different in both groups.

Impact of COVID-19 on Outcomes of Patients Hospitalized With STEMI: A Nationwide Propensity-matched Analysis.

Patients with ST-segment elevation myocardial infarction (STEMI) and concurrent coronavirus disease 2019 (COVID-19) have been reported to have poor outcomes. However, previous studies are small and limited. The National Inpatient Sample database for the year 2020 was queried to identify all adult hospitalizations with a primary diagnosis of STEMI, with and without concurrent COVID-19. A 1:1 propensity score matching was performed. A total of 159,890 hospitalizations with a primary diagnosis of STEMI were identified. Of these, 2210 (1.38%) had concurrent COVID-19. After propensity matching, STEMI patients with concurrent COVID-19 had a significantly higher mortality (17.8% vs 9.1%, OR 1.96, P< 0.001), lower likelihood to receive same-day percutaneous coronary intervention (PCI) (63.6% vs 70.6%, P = 0.019), with a trend towards lower overall PCI (74.9% vs 80.2%, P = 0.057) and significantly lower coronary artery bypass grafting) (3.0% vs 6.8%, P = 0.008) prior to discharge, compared with STEMI patients without COVID-19. The prevalence of cardiogenic shock, need for mechanical circulatory support, extracorporeal membrane oxygenation, cardiac arrest, acute kidney injury (AKI), dialysis, major bleeding and stroke were not significantly different between the groups. COVID-19-positive STEMI patients who received same-day PCI had significantly lower odds of in-hospital mortality (adjusted OR 0.42, 95% CI 0.20-0.85, P = 0.017). STEMI patients with concurrent COVID-19 infection had a significantly higher (almost 2 times) in-hospital mortality, and lower likelihood of receiving same-day PCI, overall (any-day) PCI, and CABG during their admission, compared with STEMI patients without COVID-19.

Impact of COVID-19 on Patients Hospitalized With Deep Vein Thrombosis and/or Pulmonary Embolism: A Nationwide Analysis.

The Coronavirus disease 2019 (COVID-19) infection predisposes patients to develop deep vein thrombosis (DVT) and pulmonary embolism (PE). In this study, we compared the in-hospital outcomes of patients with DVT and/or PE with concurrent COVID-19 infection vs those with concurrent flu infection. The National Inpatient Sample from 2019 to 2020 was analyzed to identify all adult admissions diagnosed with DVT and PE. These patients were then stratified based on whether they had concomitant COVID-19 or flu. We identified 62,895 hospitalizations with the diagnosis of DVT and/or PE with concomitant COVID-19, and 8155 hospitalizations with DVT and/or PE with concomitant flu infection. After 1:1 propensity score match, the incidence of cardiac arrest and inpatient mortality were higher in the COVID-19 group. The incidence of cardiogenic shock was higher in the flu group. Increased age, Hispanic race, diabetes, chronic kidney disease, arrhythmia, liver disease, coagulopathy, and rheumatologic diseases were the independent predictors of mortality in patients with DVT and/or PE with concomitant COVID-19.

COVID-19, Heart Failure Hospitalizations, and Outcomes: A Nationwide Analysis.

Heart Failure (HF) patients are at a higher risk of adverse events associated with Coronavirus disease 2019 (COVID-19). Large population-based reports of the impact of COVID-19 on patients hospitalized with HF are limited. The National Inpatient Sample database was queried for HF admissions during 2020 in the United States (US), with and without a diagnosis of COVID-19 based on ICD-10-CM U07. Propensity score matching was used to match patients across age, race, sex, and comorbidities. Multivariate logistic regression analysis was used to identify predictors of mortality. A weighted total of 1,110,085 hospitalizations for HF were identified of which 7,905 patients (0.71%) had a concomitant diagnosis of COVID-19. After propensity matching, HF patients with COVID-19 had higher rate of in-hospital mortality (8.2% vs 3.7%; odds ratio [OR]: 2.33 [95% confidence interval [CI]: 1.69, 3.21]; P< 0.001), cardiac arrest (2.9% vs 1.1%, OR 2.21 [95% CI: 1.24,3.93]; P<0.001), and pulmonary embolism (1.0% vs 0.4%; OR 2.68 [95% CI: 1.05, 6.90]; P = 0.0329). During hospitalizations for HF, COVID-19 was also found to be an independent predictor of mortality. Further, increasing age, arrythmias, and chronic kidney disease were independent predictors of mortality in HF patients with COVID-19. COVID-19 is associated with increased in-hospital mortality, longer hospital stays, higher cost of hospitalization and increased risk of adverse outcomes in patients admitted with HF.

Impact of COVID-19 in patients hospitalized with stress cardiomyopathy: A nationwide analysis.

Stress cardiomyopathy was noted to occur at a higher incidence during coronavirus disease of 2019 (COVID-19) pandemic. This database analysis has been done to compare the in-hospital outcomes in patients with stress cardiomyopathy and concurrent COVID-19 infection with those without COVID-19 infection. The National Inpatient Sample database for the year 2020 was queried to identify all admissions diagnosed with stress cardiomyopathy. These patients were then stratified based on whether they had concomitant COVID-19 infection or not. A 1:1 propensity score matching was performed. Multivariate logistic regression analysis was done to identify predictors of mortality. We identified 41,290 hospitalizations for stress cardiomyopathy, including 1665 patients with concurrent diagnosis of COVID-19. The female preponderance was significantly lower in patients with stress cardiomyopathy and COVID-19. Patients with concomitant COVID-19 were more likely to be African American, diabetic and have chronic kidney disease. After propensity matching, the incidence of complications, including acute kidney injury (AKI), AKI requiring dialysis, coagulopathy, sepsis, cardiogenic shock, cases with prolonged intubation of >24 h, requirement of vasopressor and inpatient mortality, were noted to be significantly higher in patients with COVID-19. Concomitant COVID-19 infection was independently associated with worse outcomes and increased mortality in patients hospitalized with stress cardiomyopathy.

Nationwide Analysis of the Outcomes and Mortality of Hospitalized COVID-19 Patients.

INTRODUCTION: The Coronavirus disease 2019 (COVID-19) pandemic has affected people worldwide with the United States (US) with the largest number of reported cases currently. Previous studies in hospitalized COVID-19 patients have been limited by sample size. METHODS: The National Inpatient Sample database which is the largest inpatient database in the US was queried in the year 2020 for the diagnosis of COVID-19 based on ICD-10-CM U07.1 and associated outcomes. Multivariate logistic regression analysis was used to identify predictors of mortality. STATA 16.0 was used for statistical analysis. RESULTS: A weighted total of 1,678,995 hospitalizations for COVID-19 were identified. Median age of admitted patients with COVID-19 was 65 year (51-77) with 47.9% female and 49.2% White. Majority of the patients admitted were >65 years of age (49.3%). Hypertension and diabetes were the most common comorbidities (64.2% and 39.5%, respectively). Overall inpatient mortality was 13.2% and increasing to 55.9% in patients requiring mechanical ventilation. Trend of inpatient mortality was significantly decreasing over the year. Predictors of inpatient mortality included age, male sex, diabetes, chronic kidney disease, heart failure, arrythmia, obesity, and coagulopathy. Despite a lower proportion of patients admitted to hospital with COVID-19, Black, Hispanic, and Native Americans were at an increased adjusted odds of inpatient mortality. Disparity was also noted in income, with low median household income associated with higher risk of mortality. CONCLUSION: In the largest US cohort with >1.6 million hospitalized COVID-19 patients in 2020, overall inpatient mortality was 13.6% with significantly higher mortality in ventilated patients. Significant socioeconomic and racial disparities were present with minorities at higher odds of mortality.
