Abstract

Abstract: Background: Coronavirus disease 2019 (COVID-19) rapidly spread worldwide since it first emerged in December 2019, with more than 100 million cases reported to date, causing a great impact on healthcare systems. Heart failure (HF) is a major health problem. It affects about 10 million people in Europe and is the leading cause of hospitalization for patients older than 65 years. During the first wave of COVID-19 there was an important decrease in HF hospitalizations. Data regarding HF admissions during the second and third waves and inter-waves periods is scarce. Purpose: To examine the impact of COVID-19 on HF hospitalizations during the first year of the pandemic and to compare the clinical characteristics and in-hospital outcomes of patients admitted during the three pandemic waves with those admitted the previous year during the same periods. Methods: Data from a tertiary Heart Failure Unit in Southern Spain between 1 March 2020 and 28 February 2021 were compared to the corresponding time period in the previous year. The impact of the pandemic on weekly hospitalizations was assessed using a Poisson Regression model, with year, season and pandemic wave as covariates. Clinical characteristics and in-hospital outcomes of patients admitted during the three waves were compared to those admitted during the same periods one year after. Results: A significantly lower weekly number of admissions for HF was observed during the three pandemic wave periods compared to all other included periods (inter-wave periods and same periods in the previous year) (p=0.002, IRR 0.81, 0.77–0.86). Figure 1 shows monthly HF admissions between 1 March 2020 and 28 February 2021 (pandemic year) and the previous year, as well as COVID-19 hospitalized cases in our area. Clinical characteristics and in-hospital outcomes of patients admitted during the COVID-19 waves and the same periods in the previous year are shown in Figure 2. Patients admitted during the COVID-19 waves were younger, and fewer had diabetes mellitus (DM), atrial fibrillation (AF) and valvular heart disease (VHD). There were no differences in clinical outcomes (intensive care unit admission, in-hospital mortality). Conclusion: There was decline in HF hospitalization during the three waves of the pandemic year, but not during the inter-wave periods. Patients admitted during the wave periods had some clinical differences but similar in-hospital outcomes. Funding Acknowledgement: Type of funding sources: None.
