The Relation of Age to Certain Measures of Performance of the Heart and the Circulation

摘要: The resting cardiac output measurements presented in the preceding article are analyzed relation to intra-arterial pressure provide estimates of peripheral circulatory state and central performance. calculated agewise increase net vascular resistance which is responsible for decrease perfusion, indicates that attrition with age, on average, outstrips expected reduction basal metabolism individual. Despite this lessened requirement, one may adduce evidences a trend toward diminished reserve age even these subjects who revealed no clinical abnormality. feasibility predicting an individual's from his blood commented upon.
