Hypertension and coronary sclerosis have been the subject of extensive study, yet they have many aspects that are still poorly understood.In the present work we have tried to ascertain how far they are dissociated and how far they overlap, and in particular we have studied their effects on the circulatory capacity of the coronary tree by injection and radiography.Over a period of four years, from 1935 to 1939, we made a careful clinical study of most of the cases of (1) No cardiac symptoms: Cases 24, 47, 60, and 69.Death was from pulmonary embolism in Case 24, from cerebral hmemorrhage in Case 47, and from uremia in Cases 60 and 69.(2) Effort dyspnoea only: Cases 23, 36, 39, 43, 44, and 65.Death was from cerebral hemorrhage in Cases 23 and 44, from herniotomy in Cases 36 and 39, from pneumonia in Case 43, and from hzema- temesis from peptic ulcer in Case 65.(3) Left ventricular failure: Cases 11, 13, 19, 41, 45, and 68.Death was from cerebral hzemorrhage in Case 11, from uremia in Cases 13, 19, 41, and 45, and from bronchopneumonia in Case 68.(4) Full course-death in congestive heart failure: Cases 8, 32, 38, 58, 62, and 63 followed previous manifestations of left ventricular failure; Cases 28, 48, 49, 50, and 53 had no such previous manifesta- tions.CLNiCAL FEATURESOwing to the arbitrary nature of the clinical grouping, the complaint was necessarily one of pain in those with ischemic heart disease: in ten it was the presenting feature, but in five it was less evident than dyspncea.For the same reason pain was not present in the hypertensive group, except in an Q 205
