Heart failure patient detection method, heart disease identification method, heart failure test reagent, heart failure test kit, heart failure detection device, and program for heart failure detection

摘要

An object of the present invention is to provide a highly specific method for detecting a cardiac failure patient, a method for discrimination of cardiac disease, a test reagent for cardiac failure, a test kit for cardiac failure, a device for detecting cardiac failure, and a program for detecting cardiac failure. In order to attain the abject, the amount or concentration of cytoskeleton-associated protein 4 (CKAP4) protein is measured in a blood sample to determine the presence of cardiac failure when the value of the amount or concentration is lower than a predetermined standard value.
