Myocarditis and pericarditis share common causes: viral infection, bacterial infection, autoimmune disease, and drug side effects. Children and young adults more often have myocardial involvement during pericarditis.
NSAIDs are the primary treatment for myopericarditis. Unlike pure myocarditis, myopericarditis does not typically lead to poor cardiovascular outcomes, such as heart failure.
