Echocardiographic Manifestation in Patients With Omicron Variant of COVID-19
Cardiac Structural and Functional Characteristics in Patients With Omicron Infection: a Dynamic Echocardiographic Study in Shanghai, China
Study Overview
Detailed Description
COVID-19 affects the cardiovascular system, and the presence of cardiovascular disease (CAD) and risk factors is associated with worse clinical outcomes in infected patients. However, there is a paucity of information regarding the cardiovascular scenario associated with omicron, the new variant of SARS-CoV-2 that causes COVID-19. Thus, we expect to perform this study to explore the echocardiographic manifestations in patients admitted to the hospital with confirmed COVID-19 infection, during the current omicron wave in Shanghai, China.
According to published guidelines, with written consent from eligible patients, participants are grouped into the severely ill group, the critically ill group, the mildly ill group, and the healthy control group. The investigators will review medical records and document detailed sociodemographic characteristics for each participant. Circulating levels of cardiac biomarkers such as B-type natriuretic peptide (BNP) and cardiac troponin (cTnI), inflammatory biomarkers such as interleukin 6 (IL-6) and high-sensitivity C-reactive protein (hs-CRP), and blood cell counts are measured in the hospital-based laboratory. To study the cardiac manifestations of the patients, echocardiography is performed using a GE Vingmed Ultrasound System (GE Healthcare, Horten, Norway), and morphological and functional parameters of the heart are measured. Clinical outcomes will be censored at the time of data cut-off, and patients after discharge will continue to be interviewed by telephone. Differences in cardiac manifestations and clinical outcomes between the groups are compared by proper statistical tests.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
ICU-Severely ill group
Patients requiring transfer to the intensive care unit (ICU), and presenting with severe symptoms (dyspnea, respiratory rate ≥30/min, blood oxygen saturation ≤93%, partial pressure of arterial oxygen to fraction of inspired oxygen ratio <300, or lung infiltrates >50% within 24 to 48 hours)
|
Echocardiography is performed using a GE Vingmed Ultrasound System (GE Healthcare, Horten, Norway), by an experienced expert.
Morphological and functional parameters of the heart are measured in a consistent manner.
|
ICU-Critically ill group
Patients requiring transfer to the ICU, and presenting with respiratory failure, septic shock, multiple organ dysfunction, or failure)
|
Echocardiography is performed using a GE Vingmed Ultrasound System (GE Healthcare, Horten, Norway), by an experienced expert.
Morphological and functional parameters of the heart are measured in a consistent manner.
|
Mildly ill group
Patients presenting with fever, mild to moderate respiratory symptoms, and with or without imaging presentations of pneumonia
|
Echocardiography is performed using a GE Vingmed Ultrasound System (GE Healthcare, Horten, Norway), by an experienced expert.
Morphological and functional parameters of the heart are measured in a consistent manner.
|
Healthy control group
Healthy volunteers, matched for gender and age, without any signs or evidence of COVID-19 infection
|
Echocardiography is performed using a GE Vingmed Ultrasound System (GE Healthcare, Horten, Norway), by an experienced expert.
Morphological and functional parameters of the heart are measured in a consistent manner.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Left atrial diameter (cm)
Time Frame: Day at the enrollment
|
Left atrial diameter (LAD) is a morphological parameter, which is measured by echocardiography to assess the size of left atrium.
|
Day at the enrollment
|
Left ventricular internal dimension at end-diastole (cm)
Time Frame: Day at the enrollment
|
Left ventricular internal dimension at end-diastole (LVIDd) is a morphological parameter, which is measured by echocardiography to assess the size of left ventricle.
|
Day at the enrollment
|
Interventricular septum thickness (mm)
Time Frame: Day at the enrollment
|
Interventricular septum thickness is a morphological parameter, which is measured by echocardiography to assess the presence of ventricular hypertrophy.
|
Day at the enrollment
|
Left ventricular ejection fraction (%)
Time Frame: Day at the enrollment
|
Left ventricular ejection fraction (LVEF) is a functional parameter, which is measured by echocardiography to assess ventricular systolic function.
|
Day at the enrollment

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
In hospital all-cause mortality (%)
Time Frame: Day at the time of data cut-off
|
To study the clinical outcome in the groups, patients are followed to death or discharge following the echocardiography.
The rate of all-cause mortality (death) is calculated as a percentage (%) for the mildly ill group, the severely ill group, and the critically ill group.
|
Day at the time of data cut-off
|
The need of invasive mechanical ventilation (%)
Time Frame: Day at the time of data cut-off
|
Since COVID-19 mainly damages the respiratory system, some severely ill and critically ill patients may need the treatment of invasive mechanical ventilation (IMV).
The percentage (%) of patients in each group receiving IMV is calculated to assess the clinical consequence of omicron infection.
