The effect of concomitant COVID‐19 infection on outcomes in patients hospitalized with heart failure

Abstract Aims Patients with cardiovascular disease appear particularly susceptible to severe COVID‐19 disease, but the impact of COVID‐19 infection on patients with heart failure (HF) is not known. This study aimed to quantify the impact of COVID‐19 infection on mortality in hospitalized patients known to have HF. Methods and results We undertook a retrospective analysis of all patients admitted with a pre‐existing diagnosis of HF between 1 March and 6 May 2020 to our unit. We assessed the impact of concomitant COVID‐19 infection on in‐hospital mortality, incidence of acute kidney injury, and myocardial injury. One hundred and thirty‐four HF patients were hospitalized, 40 (29.9%) with concomitant COVID‐19 infection. Those with COVID‐19 infection had a significantly increased in‐hospital mortality {50.0% vs. 10.6%; relative risk [RR] 4.70 [95% confidence interval (CI) 2.42–9.12], P
