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.

Assessment of the Cardiovascular System I: Subjective Data

A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
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...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

Imaging Studies for Cardiovascular System I:Echocardiography

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
