SHM Converge Scientific Abstract ePoster Gallery-Reduced Rates of Hospitalzations Accompanied by Increased Mortality for Heart Failure in Covid-19 Pandemic, Mar-Oct 2020

Pdf Summary

This multicenter study examined 8,989 hospitalizations for acute decompensated heart failure (ADHF) across seven hospitals in three U.S. states, comparing the early COVID-19 pandemic period (March–October 2020) with a pre-pandemic period (October 2018–February 2020). The authors also performed a systematic review and meta-analysis of 17 published studies.<br /><br />The study found a clear decline in ADHF hospitalizations during the pandemic, especially among older adults and those with more comorbidities. Among hospitalized patients, treatment patterns were largely unchanged: use of heart failure medications, surgical interventions, devices, critical care admission, and in-hospital mortality did not differ significantly between time periods. However, some care patterns shifted, with more patients admitted to non-cardiology services or discharged home with self-care during the pandemic.<br /><br />Despite similar in-hospital care, 30-day outcomes worsened. Adjusted 30-day all-cause readmissions decreased from 13% to 10%, but 30-day mortality increased from 9.7% to 11.3%. In the meta-analysis, there was no consistent difference in in-hospital mortality or readmissions overall, but 30-day mortality was 18% higher during the pandemic across pooled studies.<br /><br />The authors conclude that the COVID-19 era was associated with fewer heart failure hospitalizations and fewer readmissions, but higher short-term mortality after hospitalization. They suggest this may reflect a distinct “COVID-19 heart failure phenotype,” characterized by younger age, fewer comorbidities, and higher 30-day mortality.
