Title: The prognostic value of serial troponin measurements in patients admitted for COVIDâ€19 Cord-id: m9s7stph Document date: 2021_7_8
ID: m9s7stph
Snippet: AIMS: Myocardial injury (MI) in coronavirus diseaseâ€19 (COVIDâ€19) is quite prevalent at admission and affects prognosis. Little is known about troponin trajectories and their prognostic role. We aimed to describe the early inâ€hospital evolution of MI and its prognostic impact. METHODS AND RESULTS: We performed an analysis from an Italian multicentre study enrolling COVIDâ€19 patients, hospitalized from 1 March to 9 April 2020. MI was defined as increased troponin level.

Document: AIMS: Myocardial injury (MI) in coronavirus diseaseâ€19 (COVIDâ€19) is quite prevalent at admission and affects prognosis. Little is known about troponin trajectories and their prognostic role. We aimed to describe the early inâ€hospital evolution of MI and its prognostic impact. METHODS AND RESULTS: We performed an analysis from an Italian multicentre study enrolling COVIDâ€19 patients, hospitalized from 1 March to 9 April 2020. MI was defined as increased troponin level. The first troponin was tested within 24 h from admission, the second one between 24 and 48 h. Elevated troponin was defined as values above the 99th percentile of normal values. Patients were divided in four groups: normal, normal then elevated, elevated then normal, and elevated. The outcome was inâ€hospital death. The study population included 197 patients; 41% had normal troponin at both evaluations, 44% had elevated troponin at both assessments, 8% had normal then elevated troponin, and 7% had elevated then normal troponin. During hospitalization, 49 (25%) patients died. Patients with incident MI, with persistent MI, and with MI only at admission had a higher risk of death compared with those with normal troponin at both evaluations (P < 0.001). At multivariable analysis, patients with normal troponin at admission and MI injury on Day 2 had the highest mortality risk (hazard ratio 3.78, 95% confidence interval 1.10–13.09, P = 0.035). CONCLUSIONS: In patients admitted for COVIDâ€19, reâ€test MI on Day 2 provides a prognostic value. A nonâ€negligible proportion of patients with incident MI on Day 2 is identified at high risk of death only by the second measurement.
