Hi:
"I appear to have a permanent heart strain"
What exactly do you mean by this? Having chest (heart area) pain or discomfort?
"Was hospitalized for 3 days"What diagnostic cardiac-related tests have you had thus far?
In general, it's well known that viruses may/can affect the heart. As it has been reported, researchers and scientists know that some viruses have what is known as
"tissue affinity", that is, it homes in on/seeks out one or two types of body tissue. Coxsackie B goes for the heart muscle (myocardium) in which the virus locks onto receptor sites thereof.
Viruses/enteroviruses, which includes Coxsackie A and B may/can cause inflammation in the brain as well as the sensitive lining of the lungs and heart (includes valves/chambers).
A virus can cause conditions such as myocarditis (inflammation of the muscle), which can lead to viral cardiomyopathy, heart muscle disease, which often leads to heart failure/congestive heart failure.
In the United States, infection with Coxsackie B virus is the most common cause of viral cardiomyopathy and viral pericarditis, which can be a result of an infection by several types of other viruses, including echoviruses, adenoviruses, the human immunodeficiency virus (HIV) and the viruses that cause mumps or hepatitis.
Dilated cardiomyopathy may/can be caused by an acute inflammation of the heart muscle (myocarditis) due to a viral infection, i.e., viral cardiomyopathy.
Best of luck down the road of life.
