BACKGROUND Increases in cardiac troponin(cTn)in coronavirus disease 2019(COVID19)have been associated with worse ***,data about the significance of cTn in elderly subjects with COVID19 are *** From a registry of consecutive patients with COVID19 admitted to a hub hospital in Italy from 25/02/2020 to 03/07/2020,we selected those≥60 yearold and with cTnI measured within three days from the molecular diagnosis of SARSCoV2 *** available,a second cTnI value within 48 h was also *** relationship between increased cTnI and allcause inhospital mortality was evaluated by a Cox regression model and restricted cubic spline functions with three *** Of 343 included patients(median age:75.0(68.0−83.0)years,34.7%men),88(25.7%)had cTnI above the upperreference limit(0.046μg/L).Patients with increased cTnI had more comorbidities,greater impaired respiratory exchange and higher inflammatory markers on admission than those with normal ***,they died more(73.9%vs.37.3%,P<0.001)over 15(6−25)days of *** association of elevated cTnI with mortality was confirmed by the adjusted Cox regression model(HR=1.61,95%CI:1.06−2.52,P=0.039)and was linear until 0.3μg/L,with a subsequent *** 191(55.7%)patients with a second cTnI measurement,49(25.7%)had an increasing trend,which was not associated with mortality(univariate HR=1.39,95%CI:0.87−2.22,P=0.265).CONCLUSIONS In elderly COVID19 patients,an initial increase in cTn is common and predicts a higher risk of *** cTn testing may not confer additional prognostic information.
