Abstract
BackgroundPrior research has linked cardiovascular diseases with higher COVID-19 mortality and worse hospital outcomes, particularly in severe heart failure. Large population-based data regarding the impact of pre-existing ischemic heart disease (IHD) on COVID-19 outcomes is not well established. ObjectiveTo study the impact of COVID-19 infection on IHD hospital mortality and other outcomes. MethodsThe study included a patient cohort from the 2020 and 2021 National Inpatient Sample (NIS) database. Propensity score matching was used to match the study cohort (COVID-19 with IHD) to controls (COVID-19 without IHD) using a 1:1 matching ratio. The outcomes analyzed were in-hospital mortality, rates of acute kidney injury (AKI), acute myocardial injury (AMI), cardiogenic shock, cardiac arrest, mechanical ventilation, tracheal intubation, pulmonary embolism (PE), ventricular tachycardia (VT), ventricular fibrillation (VF), length of stay (LOS), and total hospitalization charges. ResultsA total of 2,532,652 patients met the inclusion criteria (1,199,008 females [47.3 %), predominantly Caucasian 1,456,203 (57.5 %); mean [SD] age 63, (5.4), including 29,315 (1.1 %) patients with a history of IHD. Following propensity matching, 4,772 COVID-19 patients with and without IHD were matched. IHD patients had higher rates of AMI (adjusted odds ratio (aOR) 3.75, 95 % CI 3.27–4.31, p < 0.001), cardiogenic shock (aOR 2.89, 95 % CI 1.60–5.19, p < 0.001), VT (aOR 3.26, 95 % CI 2.48–4.29, p < 0.001), and VF (aOR 2.23, 95 % CI 1.25–3.99, p < 0.001). The odds ratios of in-hospital mortality, AKI, PE, mechanical ventilation, tracheal intubation, and resource use were not significantly different. ConclusionA history of IHD does not impact COVID-19 mortality but increases the risk of in-hospital cardiac complications.
