Heart Muscle Inflammation (Myocarditis): Complications

The following are the most important diseases or complications that can be caused by myocarditis (inflammation of the heart muscle):

Cardiovascular disorders (I00-I99).

Symptoms and abnormal clinical and laboratory findings not elsewhere classified (R00-R99).

Further

  • High 10-year mortality (death rate) of viral myocarditis: nearly 40% of affected patients died within the next 10 years, according to an analysis by German cardiologists.Prognostic factors are:
    • Detection of necrosis and fibrosis areas by late contrast enhancement, “late gadolinum enhancement” (LGE): this was associated with twice the mortality risk (risk of death) compared with unremarkable patients: the risk of dying from a cardiac (heart-related) cause increased 3-fold, and the risk of cardiac death increased 14-fold.
    • LGE + LVEF (left ventricular ejection fraction; ejection fraction of the heart) ≤ 40%: poor survival.
