Insights
COVID-19 patients face increased risks of cardiovascular diseases (CVDs). Acute coronary syndrome (ACS) significantly raises mortality, while acute pulmonary embolism (APE) and acute myocarditis (AMyo) do not independently impact death risk in COVID-19 patients.
Area of Science:
- Cardiology
- Infectious Diseases
- Pulmonology
Background:
- COVID-19 is associated with an elevated risk of acute cardiovascular diseases (CVDs), including acute coronary syndrome (ACS), acute pulmonary embolism (APE), and acute myocarditis (AMyo).
- The precise influence of these CVDs on COVID-19 patient mortality remains incompletely understood.
- This study investigates the impact of CVDs on COVID-19 pneumonia progression and their detectability using standard clinical tools.
Purpose of the Study:
- To determine if CVDs affect the clinical course of COVID-19 pneumonia.
- To assess the utility of common diagnostic tests and examinations in identifying CVDs in COVID-19 patients.
- To analyze the independent impact of ACS, APE, and AMyo on in-hospital mortality among COVID-19 patients.
Main Methods:
- Analysis of data from 249 consecutive COVID-19 patients admitted to a cardiology department.
- Inclusion of clinical status, biomarker levels, computed tomography (CT) scans, and bedside echocardiography upon admission.
- Statistical analysis to evaluate predictive values of biomarkers and the influence of CVDs on mortality, adjusting for lung involvement.
Main Results:
- D-dimer levels effectively predicted APE (AUC=0.850), with a sensitivity of 69.4% and specificity of 96.2% at a threshold of 4968.0 ng/mL.
- NT-proBNP levels predicted AMyo (AUC=0.692), showing 54.5% sensitivity and 86.5% specificity at a cut-off of 8970 pg/mL.
- Troponin T levels were not diagnostically useful for differentiating CVDs. Lung involvement extent predicted mortality (OR=1.03). ACS independently increased mortality (OR=5.27), whereas APE and AMyo did not significantly affect death risk after adjusting for lung disease.
Conclusions:
- D-dimer and NT-proBNP are valuable biomarkers for differentiating CVDs in COVID-19 patients, unlike troponin T.
- Acute coronary syndrome in conjunction with COVID-19 significantly elevates in-hospital mortality, independent of lung disease severity.
- Acute pulmonary embolism and acute myocarditis, when co-occurring with COVID-19, did not demonstrate an independent impact on in-hospital mortality in this cohort.
Abstract:
BACKGROUND COVID-19 increases the risk of acute cardiovascular diseases (CVDs), including acute coronary syndrome (ACS), acute pulmonary embolism (APE), and acute myocarditis (AMyo). The actual impact of CVDs on mortality of patients with COVID-19 remains unknown. This study aimed to determine whether CVDs influence the course of COVID-19 pneumonia and if they can be easily detected by using common tests and examinations. MATERIAL AND METHODS Data of 249 consecutive patients with COVID-19 hospitalized in a dedicated cardiology department were analyzed. On admission, clinical status, biomarkers, computed tomography, and bedside echocardiography were performed. RESULTS D-dimer level predicted APE (AUC=0.850 95% CI [0.765; 0.935], P<0.001) with sensitivity of 69.4% and specificity of 96.2% for a level of 4968.0 ng/mL, and NT-proBNP predicted AMyo (AUC=0.692 95% CI [0.502; 0.883], P=0.004) and showed sensitivity of 54.5%, with specificity of 86.5% for the cut-off point of 8970 pg/mL. Troponin T levels were not useful for diagnostic differentiation between CVDs. An extent of lung involvement predicted mortality (OR=1.03 95% CI [1.01;1.04] for 1% increase, P<0.001). After adjusting for lung involvement, ACS increased mortality, compared with COVID-19 pneumonia only (OR=5.27 95% CI [1.76; 16.38] P=0.003), while APE and AMyo did not affect risk for death. CONCLUSIONS D-dimer and NT-proBNP, but not troponin T, are useful in differentiating CVDs in patients with COVID-19. ACS with COVID-19 increased in-hospital mortality independently from extent of lung involvement, while coexisting APE or AMyo did not.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
