Cardiac injuries in patients with coronavirus disease 2019: Not to be ignored
Insights
Older patients with COVID-19 (coronavirus disease 2019) who experienced cardiac injury showed higher mortality. Elevated hs-Troponin I (hs-TnI) levels indicated a poor prognosis, potentially linked to inflammation and coagulation issues.
Area of Science:
- Critical Care Medicine
- Infectious Diseases
- Cardiology
Background:
- Coronavirus disease 2019 (COVID-19) is a global health crisis.
- Understanding the clinical manifestations and prognostic factors of COVID-19 is crucial for patient management.
- Cardiac involvement in COVID-19 patients requires further investigation.
Purpose of the Study:
- To elucidate the clinical features of COVID-19 patients.
- To identify predictors of mortality in COVID-19.
- To explore the role of cardiac injury in COVID-19 outcomes.
Main Methods:
- Retrospective analysis of 73 intensive care unit (ICU) patients with COVID-19.
- Collected demographic, comorbidity, and laboratory data upon admission.
- Compared clinical characteristics and outcomes between survivors and non-survivors.
Main Results:
- Non-survivors were older and had more comorbidities than survivors.
- Elevated C-reactive protein, interleukin-6, D-dimer, and hs-Troponin I (hs-TnI) were observed in non-survivors.
- Higher hs-TnI levels correlated with shorter survival time and increased mortality risk, though this association weakened after adjusting for inflammatory and coagulation markers.
Conclusions:
- Cardiac injury is a significant early complication of COVID-19, associated with increased mortality.
- Inflammatory factor cascade and coagulation abnormalities are potential mechanisms underlying COVID-19-related cardiac injury.
Objective:
To describe the clinical features of coronavirus disease 2019 (COVID-19).
Methods:
We recruited 73 patients with COVID-19 [49 men and 24 women; average age: 58.36 years (SD: 14.31)] admitted to the intensive care unit of Wuhan Jinyintan Hospital from December 30, 2019 to February 16, 2020. Demographics, underlying diseases, and laboratory test results on admission were collected and analyzed. Data were compared between survivors and non-survivors.
Results:
The non-survivors were older (65.46 [SD 9.74]vs 46.23 [12.01]) and were more likely to have chronic medical illnesses. Non-survivors tend to develop more severe lymphopenia, with higher C-reactive protein, interleukin-6, D-dimer, and hs-Troponin I(hs-TnI) levels. Patients with elevated hs-TnI levels on admission had shorter duration from symptom onset to death. Increased hs-TnI level was related to dismal prognosis. Death risk increased by 20.8% when the hs-TnI level increased by one unit. After adjusting for inflammatory or coagulation index, the independent predictive relationship between hs-TnI and death disappeared.
Conclusions:
Cardiac injury may occur at the early stage of COVID-19, which is associated with high mortality. Inflammatory factor cascade and coagulation abnormality may be the potential mechanisms of COVID-19 combined with cardiac injury.
