Insights
COVID-19 can harm the heart, leading to conditions like myocarditis and heart failure. This study uses a computational model to explore how COVID-19 affects cardiac and pulmonary functions in patients.
Area of Science:
- Cardiovascular Medicine
- Computational Biology
- Infectious Diseases
Background:
- COVID-19 infection is increasingly linked to cardiovascular complications.
- These complications include myocardial injury, acute coronary syndrome, myocarditis, arrhythmia, and heart failure.
- Understanding the cardiovascular impact of COVID-19 is crucial for patient management.
Purpose of the Study:
- To investigate the interplay between local cardiac changes, global cardiovascular variables, and overall cardiac function in COVID-19 patients.
- To develop and utilize a computational model to simulate cardiovascular and pulmonary interactions.
- To assess cardiac function parameters in virtual subjects with varying COVID-19 severity.
Main Methods:
- Employed a lumped parameters computational model of the cardiovascular system.
- Utilized a three-dimensional multiphysics model of cardiac electromechanics.
- Simulated systemic and pulmonary circulations, cardiac valves, and chambers using physical process equations.
Main Results:
- The computational model successfully simulated cardiovascular dynamics.
- Assessed key cardiac function parameters through numerical simulations.
- Revealed interactions between cardiac and pulmonary functions in simulated COVID-19 scenarios.
Conclusions:
- A novel computational model can effectively reveal cardiac and pulmonary function interactions.
- The model aids in understanding cardiovascular impacts of COVID-19 in diverse patient profiles.
- This approach offers insights for prospective treatment strategies in COVID-19 patients with cardiac involvement.
Abstract:
Emerging studies address how COVID-19 infection can impact the human cardiovascular system. This relates particularly to the development of myocardial injury, acute coronary syndrome, myocarditis, arrhythmia, and heart failure. Prospective treatment approach is advised for these patients. To study the interplay between local changes (reduced contractility), global variables (peripheral resistances, heart rate) and the cardiac function, we considered a lumped parameters computational model of the cardiovascular system and a three-dimensional multiphysics model of cardiac electromechanics. Our mathematical model allows to simulate the systemic and pulmonary circulations, the four cardiac valves and the four heart chambers, through equations describing the underlying physical processes. By the assessment of conventionally relevant parameters of cardiac function obtained through our numerical simulations, we propose a computational model to effectively reveal the interactions between the cardiac and pulmonary functions in virtual subjects with normal and impaired cardiac function at baseline affected by mild or severe COVID-19.

Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...

Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...
Imbalances in Cardiac Output
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...
