Abstract
A total of fourty-eight cases of various cardiovascular diseases were throughly examined clinico-pathologically, classifying according to the types and degrees of CHF into four groups, namely A-, B-, C-, and D-groups, of which, however, D-group alone was essentially free of apparent CHF and thus to be considered as the control to the others. Thus from these studies there may be revealed to some extent the characteristic correlations between the clinical features and the pathological findings, especially concerned with the therapeutic responsibilities thereof. In conclusion it may be emphasized in this paper that the active or progressive myocardial degeneration not infrequently leading to some protracted shock-like states without evident backward congestion as typically demonstrated in the present A-group may be mainly responsible for the so-called "refractory " CHF in the strict sense, though there the mechanical factors such as valvular deformities per se seem rather mild, and in general vice versa as verified somewhat in the other groups.
