What causes viral myocarditis?
Potential causes include: Viruses.
Many viruses are commonly associated with myocarditis, including the viruses that cause the common cold (adenovirus); COVID-19; hepatitis B and C; parvovirus, which causes a mild rash, usually in children (fifth disease); and herpes simplex virus..
Can the flu cause myocarditis?
Acute myocarditis is a well-known complication of influenza infection. The frequency of myocardial involvement in influenza infection varies widely, with the clinical severity ranging from asymptomatic to fulminant varieties.
Does the flu cause heart inflammation?
Having any kind of viral infection, such as the flu, makes the heart work harder. In an effort to fight off the infection, the body releases chemicals that often cause inflammation, blood clotting and elevated blood pressure.
Can the flu damage your heart?
Flu is a respiratory illness and because of that, patients can develop problems with appropriate oxygen levels, which can affect every organ in the body, including the heart. It can especially take a toll on the heart if you already have heart problems.
How is myocarditis detected?
Myocarditis is preliminarily diagnosed by detecting signs of irritation of heart muscle during the patient’s history and physical exam. Blood tests for heart muscle enzymes (CPK levels) can be elevated. Electrical testing (EKG) can suggest irritation of heart muscle and document irregular beating of the heart.
Is myocarditis the same as a heart attack?
Myocarditis can also mimic a heart attack. When cardiac inflammation occurs in the regions of the heart nearest to the outside surface, it can present as chest pain. However, in myocarditis the coronary vasculature, which supplies the heart and is generally blocked in heart attacks, usually appears normal 1.
Can viral myocarditis recur?
Can Myocarditis Recur? Yes, myocarditis can recur, and in some cases can lead to a chronically enlarged heart (called dilated cardiomyopathy). There is no known way to prevent recurrence of myocarditis. However, the risk of recurrence is low (probably about 10 to 15 percent).
What is the most common cause of myocarditis?
Viral infection is the most common cause of myocarditis. When you have one, your body produces cells to fight the virus. These cells release chemicals. If the disease-fighting cells enter your heart, some chemicals they release can inflame your heart muscle.
Is viral myocarditis contagious?
The viruses are spread through contact with body fluids of an infected person and can also be transmitted from a pregnant woman to a fetus during pregnancy. This is the most common cause of myocarditis, blamed for about half of all US cases.
Can flu cause irregular heartbeat?
It may begin with mild flu-like symptoms such as fever, but as the heart muscle gets weakened by the viral infection, you may experience: Chest pain. Shortness of breath (at rest or during physical activity) Abnormal heartbeat (arrhythmia)
What does heart inflammation feel like?
Inflammation of the heart often causes chest pain, and you may feel like you are having a heart attack.
Can lung issues cause heart palpitations?
Pulmonary hypertension can cause irregular heartbeats (arrhythmias), which can lead to a pounding heartbeat (palpitations), dizziness or fainting.
Will myocarditis go away?
Usually, a mild case of myocarditis will go away without any lasting damage. Severe cases may not be diagnosed until you have the symptoms of heart failure. Even severe cases may go away without notice, but these severe cases usually cause ongoing and irreversible damage to the heart muscle.
Can you recover from viral cardiomyopathy?
“With current therapy, 40% to 50% of people with new-onset viral cardiomyopathy will recover their earlier level of heart function.
How long does viral myocarditis last?
In many cases, myocarditis improves on its own or with treatment, leading to a complete recovery. Myocarditis treatment focuses on the cause and the symptoms, such as heart failure. In mild cases, persons should avoid competitive sports for at least three to six months.
