Congestive heart failure may occur in late stage, which is caused by myocarditis or myocardial fibrosis. Occasional myocarditis. The myocardial isoenzyme of CK may be increased, but it is not necessarily related to myocardial involvement. Most of them are produced by regenerated myofibrils of damaged muscle.
