Is dilated cardiomyopathy infection?
Viral infections, and some hormonal disorders are common causes of dilated cardiomyopathy. Shortness of breath and fatigue are often the first symptoms. Electrocardiography, echocardiography, and magnetic resonance imaging are used to diagnose dilated cardiomyopathy.
What causes dilated cardiomyopathy with myocarditis?
Up to 20% of myocarditis patients may subsequently develop a chronic inflammatory dilated cardiomyopathy (DCMi). Although myocarditis can result from a vast number of viruses, bacteria, protozoa, or fungi,4 the most frequently identified trigger is a narrow spectrum of viruses.
What can cause cardiomyopathy?
Certain health conditions or behaviors that can lead to acquired cardiomyopathy include:
- Long-term high blood pressure.
- Heart tissue damage from a heart attack.
- Long-term rapid heart rate.
- Heart valve problems.
- COVID-19 infection.
- Certain infections, especially those that cause inflammation of the heart.
What is the most common cause of infectious myocarditis in the United States?
In the United States and other developed countries, viral infections are most frequently the cause of myocarditis. In developing countries, rheumatic carditis, Chagas disease, and complications related to advanced HIV/AIDS also provide important causes of myocarditis.
Can EBV cause cardiomyopathy?
Epstein-Barr virus is a rare cause of myocarditis. We could locate only 15 cases (9 adults and 6 children) reported in the medical literature in English. We report an adult patient who presented with signs and symptoms of heart failure most likely secondary to myocarditis caused by Epstein-Barr virus infection.
Is dilated cardiomyopathy the same as myocarditis?
Myocarditis is, by definition, an inflammatory disorder, while dilated cardiomyopathy (DCM) is, in most cases, idiopathic. However, accumulating data has revealed an important inflammatory component in the pathogenesis of DCM, and there is growing evidence that myocarditis and DCM are closely related.
Can a viral infection cause congestive heart failure?
An rare type of heart failure known as viral cardiomyopathy is triggered by a viral infection. Most people with heart failure can trace it to long-standing cardiac risks.
Can Covid cause DCM?
It is postulated that persistent immune activation upon viral infection increases the risk of developing dilated cardiomyopathy in COVID-19 patients.
Can viral infection cause dilated cardiomyopathy?
Myocarditis, an inflammatory disease of heart muscle, is an important cause of dilated cardiomyopathy worldwide. Viral infection is also an important cause of myocarditis, and the spectrum of viruses known to cause myocarditis has changed in the past 2 decades.
