Can myocarditis lower ejection fraction?

Can myocarditis lower ejection fraction?

From 210 patients who had biopsy-proven myocarditis, and came to our hospital with ECG changes, elevated troponin levels and impaired ejection fraction (EF), we found that in 47% the cases, EF did not recover to normal (gray and yellow) after 2-y standard heart failure therapy.

Can your heart go back to normal after myocarditis?

Some people with myocarditis might have chronic and irreversible damage to the heart muscle requiring lifelong medications, while other people need medications for just a few months and then recover completely.

Are there long-term effects from myocarditis?

Severe myocarditis can permanently damage your heart muscle, possibly causing: Heart failure. Untreated, myocarditis can damage your heart’s muscle so that it can’t pump blood effectively. In severe cases, myocarditis-related heart failure may require a ventricular assist device or a heart transplant.

Can myocarditis last for years?

In a small number of cases, myocarditis may persist and become chronic or long lasting. Chronic myocarditis is associated with dilated cardiomyopathy and may lead to heart failure and other serious complications. Treatment may involve long-term use of steroid medication or a heart transplant operation.

Can myocarditis cause sudden death?

Myocarditis has been reported to be a major cause of sudden and unexpected death in infants, adolescents, and young adults.

What is the prognosis for myocarditis?

The prognosis for patients with acute myocarditis who rapidly recover is very good. Even patients that develop severe myocarditis can completely recover with mild or no complications. However, if damage to the heart muscle becomes chronic and/or progressive, the prognosis for the patient declines.

Is myocarditis a chronic condition?

Myocarditis is an inflammatory disease of the heart, which can persist over a long time. During this time, known as the chronic phase of myocarditis, ongoing inflammation damages the cardiomyocytes.

Is there a link between myocarditis and inflammatory cardiomyopathy?

In this Review, we summarize and evaluate the available evidence on the pathogenesis, diagnosis and treatment of myocarditis and inflammatory cardiomyopathy, with a special focus on virus-induced and virus-associated myocarditis.

What is the prognosis for inflammatory cardiomyopathy?

Despite extensive research, inflammatory cardiomyopathy complicated by left ventricular dysfunction, heart failure or arrhythmia is associated with a poor prognosis. At present, the reason why some patients recover without residual myocardial injury whereas others develop dilated cardiomyopathy is unclear.

Can a cardiogenic shock be caused by myocarditis?

Furthermore, fulminant myocarditis, a rare, sudden and severe cardiac inflammation, is one of the main causes of cardiogenic shock in young adults 4, 5. Prompt diagnosis and specific treatment strategies are needed to reduce mortality and the need for heart transplantation in these patients 4, 5.

What kind of bacteria causes myocarditis in humans?

Myocarditis is an inflammatory cardiac disorder induced predominantly by viruses 6, 7 but also by other infectious agents including bacteria (such as Borrelia spp.), protozoa (such as Trypanosoma cruzi) and fungi.
