COVID-19-induced cardiovascular damage differs from other prevalent viruses

Area of Science:

• Cardiovascular pathology
• Infectious disease
• Immunology

Background:

• Viral infections, including COVID-19, pose a global health threat across all demographics.
• Severe COVID-19 is linked to significant cardiovascular disease (CVD) complications such as heart failure and stroke.
• CVD encompasses a range of heart and blood vessel disorders.

Purpose of the Study:

• To investigate the mechanisms by which viral infections, particularly COVID-19, induce cardiovascular disease.
• To identify risk factors associated with severe viral-induced CVD.
• To compare the CVD-inducing mechanisms of COVID-19 with other viral pathologies.

Main Methods:

• Literature review of databases including PubMed, Google Scholar, CDC, and Lexi-Comp.
• Searches focused on terms like "COVID-19 and cardiovascular pathology" and "Viral infection induced heart damage."
• Analysis of identified mechanisms and risk factors.

Main Results:

• COVID-19-induced CVD mechanisms include direct viral entry, inflammation, cytokine storm, hypoxia, and plaque destabilization.
• Other viral infections can also cause CVD through similar pathways like inflammation and cytokine storm.
• Older age, male sex, and higher body mass index (BMI) are identified risk factors for severe viral-associated CVD complications.

Conclusions:

• Viral infections share common mechanisms in causing CVD, but COVID-19 may lead to more severe outcomes due to distinct and heightened cytokine responses.
• Understanding these mechanisms is crucial for managing and preventing viral-induced cardiovascular complications.
• Risk stratification for CVD in viral infection patients should consider age, sex, and BMI.
