Aims To explore the epidemiological and clinical features of 2019 novel coronavirus(2019-nCoV)-infected patients with cardiac injury . Methods and results Data were collected from patients medical records, and we defined cardiac injury according to cardiac biomarker troponin I level > 0.03>ug/L. Among the 291 patients, 15 (5.2%) showed evidence of cardiac injury. Of 16 hospitalized patients with cardiac injury, the median age was 62 years, and 11/15 (73.3%) were men. Underlying cardiovascular diseases in some patients were hypertension (n=7, 46.6%), coronary heart disease (n=3, 20%) and diabetes (n=3, 20%). The most common symptoms at illness onset in patients with cardiac injury were fever (n=11, 73.3%), cough (n=7, 46.7%), headache or fatigue (n=5, 33.3%) and dyspnoea (n=4, 26.6%). These patients had higher systolic pressures, and lower lymphocyte counts and platelet counts, compared with patients without cardiac injury, respectively. Bilateral infiltrates on chest X-ray and elevated C-reactive protein occurred in all patients with cardiac injury. Compared with patients without cardiac injury, patients with cardiac injury were more likely to develop acute respiratory distress syndrome (73.3%), and receive mechanical ventilation (53.4%), continuous renal replacement therapy (33.3%), extracorporeal membrane oxygenation (26.7%) and vasopressor therapy (26.7%) and be admitted to the intensive care unit (73.3%). One patient died during the study. Conclusion Cardiac injury is a common condition among patients infected with 2019-nCoV.Compared with patients without cardiac injury, the clinical outcomes of patients with cardiac injury are relatively worse.
