Clinical Diagnosis Of the "Latent" Ischemic Heart Failure

概要

Parameters obtained with several procedures assessing cardiac function which are handy enough to be carried out almost routinely were studied on their correlativity to obvious changes in the clinical course and on the difference between following three groups~ healthy subjects, ischemic heart disease without signs of heart failure and overt ischemic heart failure. It was clearly shown that most of the non-failing ischemic subjects were in the status of the latent heart failure, the range of distribution of the parameters in the ischemic heart disease being between those in the healthy and ischemic heart failure. Among the procedures studied, the ear-piece dye-dilution method was the most useful in the sense that it reflected cardiac function as it was at the time of the examination, while some other indices such as P wave duration in ECG and Q-I interval were rather poor in variability in relation to the clinical course. Actually P wave duration remained unchanged often long after the complete disappearance of signs of heart failure.
