Defining heart disease risk for death in COVID-19 infection

Abstract
Background: Cardiovascular disease (CVD) was in common in Coronavirus Disease 2019 (COVID-19) patients and associated with unfavorable outcomes. We aimed to compare the clinical observations and outcomes of SARS-CoV-2-infected patients with or without CVD.
Methods: Patients with laboratory-confirmed SARS-CoV-2 infection were clinically evaluated at Wuhan Seventh People’s Hospital, Wuhan, China, from January 23 to March 14, 2020. Demographic data, laboratory findings, comorbidities, treatments and outcomes were collected and analyzed in COVID-19 patients with and without CVD.
Results: Among 596 patients with COVID-19, 215 (36.1%) of them with CVD. Compared with patients without CVD, these patients were significantly older (66 years vs 52 years) and had higher proportion of men (52.5% vs 43.8%). Complications in the course of disease were more common in patients with CVD, included acute respiratory distress syndrome (22.8% vs 8.1%), malignant arrhythmias (3.7% vs 1.0%) including ventricular tachycardia/ventricular fibrillation, acute coagulopathy(7.9% vs 1.8%), and acute kidney injury(11.6% vs 3.4%). The rate of glucocorticoid therapy (36.7% vs 25.5%), Vitamin C (23.3% vs 11.8%), mechanical ventilation (21.9% vs 7.6%), intensive care unit admission (12.6% vs 3.7%) and mortality (16.7% vs 4.7%) were higher in patients with CVD (both p < 0.05). The multivariable Cox regression models showed that older age (≥65 years old) (HR 3.165, 95%CI 1.722-5.817) and patients with CVD (HR 2.166, 95%CI 1.189-3.948) were independent risk factors for death.
Conclusion: CVD are independent risk factors for COVID-19 patients. COVID-19 patients with CVD were more severe and had higher mortality rate, early intervention and vigilance should be taken.
