Insights
COVID-19 significantly impacted patients with heart failure, revealing racial disparities in mortality risk factors. Tailored risk assessment and management are crucial for equitable healthcare outcomes.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- The COVID-19 pandemic presented major challenges to healthcare systems globally.
- Patients with comorbidities, such as heart failure, experienced high incidence and mortality rates.
- Understanding these impacts across different racial groups is incomplete.
Purpose of the Study:
- To investigate the characteristics of heart failure and comorbidities during the COVID-19 pandemic.
- To identify variations in clinical biomarkers and mortality factors among different racial groups.
- To highlight the need for customized risk assessment and management strategies.
Main Methods:
- Analysis of a large cohort of 4711 patients, divided into congestive heart failure (CHF) and non-CHF groups.
- Biomarker analysis (blood urea nitrogen, aspartate aminotransferase, white blood cell count).
- Univariate logistic regression, univariate Cox regression, and Kaplan-Meier analysis stratified by race.
Main Results:
- Significant variations in biomarkers were observed based on CHF status.
- Racial stratification revealed significant differences in multiple variables, including CHF prevalence.
- Age and comorbidity were prominent mortality factors, with distinct patterns among racial groups.
Conclusions:
- The study identified distinct mortality risk factors for heart failure during the COVID-19 pandemic across different racial groups.
- Findings underscore the importance of tailored risk assessment and management for diverse populations.
- Results support the development of targeted interventions to promote equitable healthcare outcomes.
Abstract:
The COVID-19 pandemic has posed unprecedented challenges to global healthcare systems, resulting in alarming incidence and mortality rates among patients with comorbidities, including heart failure. Understanding the characteristics of heart failure and other comorbidities during the COVID-19 pandemic is crucial for effective prevention and treatment. However, the current understanding of these characteristics among different racial groups remains incomplete. In this study, we investigated a cohort of 4711 patients, classifying them into congestive heart failure (CHF) and non-CHF groups. Biomarker analysis revealed noteworthy variations in blood urea nitrogen, aspartate aminotransferase, and white blood cell levels based on the presence or absence of CHF. Stratified by three racial groups, univariate logistic regression analysis identified significant differences in multiple variables, including CHF. Subsequent univariate Cox regression and Kaplan-Meier analysis demonstrated variations in mortality factors among distinct populations, with age and comorbidity playing prominent roles. This study utilized a large-scale database to investigate the characteristics of heart failure and related variables during the COVID-19 pandemic. The findings revealed distinctive mortality risk factors among various racial groups, emphasizing the significance of customized risk assessment and management approaches for diverse populations. These findings also provide a valuable resource for the development of targeted interventions and the promotion of equitable healthcare outcomes in the context of the COVID-19 pandemic.
