ardiac muscle marked by an increase ofthe interstitial connective tissue with waste of muscle fiber. Itcorresponds to the nutritional type of arteriosclerosis. It is theusual form of senile degeneration and in its milder form is normal. Etiology.—Myofibrosis is due to impaired nutrition eitherfrom some fault in the blood or from diminished supply throughcoronary sclerosis. As myofibrosis is one of the terminal results of malnutri-tion whether due to impaired quality of the blood or to diminishedquantity, anything which will cause either of these may producea myocarditis and consequent degeneration. The diminishedblood supply causes insufficient repair of muscle waste, butthere is sufficient to supply hyperplastic connective tissue whichrequires less nutrition or perhaps the blood of the aged containsmore of the nutritional elements required by the connectivetissue and less of the elements required to repair muscle w^aste.This would explain the general tendency to fibrosis in oldage.

This can often be demonstratedto be of different ages, and in the older parts calcareouschange may have occurred. SENILE MYOFIBROSIS 97 Satterthwaite has shown how an embolus from chronicendocarditis might be arrested in a branch of the coronaryartery and produce local infarct with fibrosis. Chronic endo-carditis may follow an acute myocarditis, endocarditis, pericardi-tis, infectious disease, syphilis, gout, nephritis, diabetes, oralcohol, lead, or tobacco intoxication. Pathology.—Senile myofibrosis affects the whole organbut the hyperplasia is most marked in the auricles. In the earlystage of the disease the heart is usually enlarged, hypertrophiedor dilated, later as the muscle waste proceeds it becomes smaller.There is an increase of connective tissue and a waste of musclefiber, but the muscle fibers are not infiltrated with granularmatter as occu
