Abstract

Background

Since the outbreak of the Coronavirus Disease 2019 (COVID-19) in China, respiratory manifestations of the disease have been observed. However, as a fatal comorbidity, acute myocardial injury (AMI) in COVID-19 patients has not been previously investigated in detail. We investigated the clinical characteristics of COVID-19 patients with AMI and determined the risk factors for AMI in them.

Methods

We analyzed data from 53 consecutive laboratory-confirmed and hospitalized COVID-19 patients (28 men, 25 women; age, 19–81 years). We collected information on epidemiological and demographic characteristics, clinical features, routine laboratory tests (including cardiac injury biomarkers), echocardiography, electrocardiography, imaging findings, management methods, and clinical outcomes.

Results

Cardiac complications were found in 42 of the 53 (79.25%) patients: tachycardia (n=15), electrocardiography abnormities (n=11), diastolic dysfunction (n=20), elevated myocardial enzymes (n=30), and AMI (n=6). All the six AMI patients were aged >60 years; five of them had two or more underlying comorbidities (hypertension, diabetes, cardiovascular diseases, and chronic obstructive pulmonary disease). Novel coronavirus pneumonia (NCP) severity was higher in the AMI patients than in patients with non-definite AMI (p<0.001). All the AMI patients required care in intensive care unit; of them, three died, two remain hospitalized. Multivariate analyses showed that C-reactive protein (CRP) levels, NCP severity, and underlying comorbidities were the risk factors for cardiac abnormalities in COVID-19 patients.

Conclusions

Cardiac complications are common in COVID-19 patients. Elevated CRP levels, underlying comorbidities, and NCP severity are the main risk factors for cardiac complications in COVID-19 patients.

    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    Our study has some limitations. First, this is a modest-size case series of hospitalized COVID-19 patients; more standardized data from a larger cohort would beneficial for further determining the clinical characteristics. Second, our data showed the clinical characteristics of AMI induced by COVID-19, including the clinical presentations, electrophysiological abnormality, myocardial enzyme and myocardial injury marker levels, and cardiac dysfunction and enlargement. However, the tissue characteristics in myocardial damage (i.e., edema, fibrosis, and microcirculation disorder) should be further demonstrated via cardiac magnetic resonance imaging examination as far as possible under the premise of controlling transmission. Finally, most of the COVID-19 patients with AMI had severe or critically severe NCP and high fatality rate, but long-term follow-up should be performed to determine adverse cardiac events in the patients who could not be diagnosed with MI but had elevated levels of one or more myocardial enzymes and myocardial injury markers. In summary, we found that cardiovascular complications are common in COVID-19 patients and include tachycardia, elevated myocardial enzyme levels, cardiac dysfunction, and even AMI. More importantly, CRP level elevation, NCP severity, and underlying cardiovascular diseases are the major risk factors for AMI in these patients.
