The amount of virally infected cardiomyocytes varies in different stages of the disease. In a mouse model, at the acute stage (7 days after infection with coxsackievirus B3) approximately 10% of the myocytes are infected and could affect overall cardiac function. In chronic murine infection, the percentage of infected cardiomyocytes are much lower.
This presentation is known as pleurodynia or Bornholm disease in many areas. Patients with chest pain should see a doctor immediately—in some cases, viruses in the Coxsackie B family progress to myocarditis or pericarditis, which can result in permanent heart damage or death. Coxsackie B virus infection may also induce aseptic meningitis.
Viral cardiomyopathy occurs when viral infections cause myocarditis with a resulting thickening of the myocardium and dilation of the ventricles. These viruses include Coxsackie B and adenovirus, echoviruses, influenza H1N1, Epstein–Barr virus, rubella (German measles virus), varicella (chickenpox virus), mumps, measles, parvoviruses, yellow fever, dengue fever, polio, rabies, and the ...
Coxsackieviruses are divided into group A and group B viruses based on early observations of their pathogenicity in neonatal mice. [1] Group A coxsackieviruses were noted to cause a flaccid paralysis (which was caused by generalized myositis) while group B coxsackieviruses were noted to cause a spastic paralysis (due to focal muscle injury and degeneration of neuronal tissue).
Around one in four deaths each year are due to heart disease; that’s 655,000 people annually. A number of factors, says Salim Hayek, MD, a cardiologist at the Michigan Medicine Frankel ...

But heart disease is multifactorial,” Dr. Tadwalkar says. He stresses that genetics plays a big role, along with diet, exercise routine, and other environmental elements like air quality.
Coxsackie A virus is a subgroup of enterovirus A, which are small, non-enveloped, positive-sense, single-stranded RNA viruses. Its protective, icosahedral capsid has an external portion that contains sixty copies of viral proteins (VP1,-2,-3) and an internal portion surrounding the RNA genome containing sixty copies of VP4 viral proteins.
