Insights
Patients with acute heart failure exacerbation and COVID-19 face significantly higher in-hospital mortality and complications like mechanical ventilation and kidney failure compared to those without COVID-19. This highlights the severe impact of concurrent COVID-19 infection on heart failure outcomes.
Area of Science:
- Cardiology
- Infectious Diseases
- Public Health
Background:
- Heart failure exacerbations are a leading cause of morbidity and mortality.
- Limited large-scale studies exist on outcomes of acute heart failure (CHF) with concurrent COVID-19.
- Understanding these outcomes is critical for patient management and public health strategies.
Purpose of the Study:
- To compare clinical outcomes in patients hospitalized with acute CHF with and without COVID-19 infection.
- To identify risk factors and disparities associated with higher mortality in this patient population.
- To inform clinical practice and resource allocation for managing CHF patients during the COVID-19 pandemic.
Main Methods:
- Utilized the National Inpatient Sample (NIS) database for a large-scale retrospective study.
- Identified 2,101,980 patients with acute CHF, including 75,215 with COVID-19.
- Employed multivariate logistic regression, adjusting for demographics, comorbidities, and hospital characteristics.
Main Results:
- Patients with acute CHF and COVID-19 had significantly higher in-hospital mortality (25.78% vs. 5.47%).
- Higher rates of vasopressor use, mechanical ventilation, sudden cardiac arrest, and acute kidney injury were observed in the COVID-19 group.
- Elderly patients, African Americans, and Hispanic individuals experienced higher mortality rates.
Conclusions:
- Concurrent COVID-19 infection dramatically increases in-hospital mortality for acute CHF exacerbations.
- COVID-19 exacerbates end-organ dysfunction, including kidney failure and cardiac arrest, in heart failure patients.
- Disparities in mortality exist among different demographic groups, warranting targeted interventions.
Abstract:
Heart failure exacerbations impart significant morbidity and mortality, however, large- scale studies assessing outcomes in the setting of concurrent coronavirus disease-19 (COVID-19) are limited. We utilized National Inpatient Sample (NIS) database to compare clinical outcomes in patients admitted with acute congestive heart failure exacerbation (CHF) with and without COVID-19 infection. A total of 2,101,980 patients (Acute CHF without COVID-19 (n = 2,026,765 (96.4%) and acute CHF with COVID-19 (n = 75,215, 3.6%)) were identified. Multivariate logistic regression analysis was utilized to compared outcomes and were adjusted for age, sex, race, income level, insurance status, discharge quarter, Elixhauser co-morbidities, hospital location, teaching status and bed size. Patients with acute CHF and COVID-19 had higher in-hospital mortality compared to patients with acute CHF alone (25.78% vs. 5.47%, adjust OR (aOR) 6.3 (95% CI 6.05-6.62, p < 0.001)) and higher rates of vasopressor use (4.87% vs. 2.54%, aOR 2.06 (95% CI 1.86-2.27, p < 0.001), mechanical ventilation (31.26% vs. 17.14%, aOR 2.3 (95% CI 2.25-2.44, p < 0.001)), sudden cardiac arrest (5.73% vs. 2.88%, aOR 1.95 (95% CI 1.79-2.12, p < 0.001)), and acute kidney injury requiring hemodialysis (5.56% vs. 2.94%, aOR 1.92 (95% CI 1.77-2.09, p < 0.001)). Moreover, patients with heart failure with reduced ejection fraction had higher rates of in-hospital mortality (26.87% vs. 24.5%, adjusted OR 1.26 (95% CI 1.16-1.36, p < 0.001)) with increased incidence of vasopressor use, sudden cardiac arrest, and cardiogenic shock as compared to patients with heart failure with preserved ejection fraction. Furthermore, elderly patients and patients with African-American and Hispanic descents had higher in-hospital mortality. Acute CHF with COVID-19 is associated with higher in-hospital mortality, vasopressor use, mechanical ventilation, and end organ dysfunction such as kidney failure and cardiac arrest.
