Prognostic Evaluation of Acute Myocardial Infarction Through Blood Chemical Examination ―A Trial to Improve the Efficiency of the Computer Assisted Laboratory Diagnosis (CALD) System of Kawasaki Medical School (KMS)―
To improve the prognostic prediction of acute myocardial infarction by (AMI) CALD (KMS), a computer assisted laboratory diagnostic system used in the Kawasaki Medical School Hospital, new tests for blood cellular elements (WBC, Lym, Pit) were added to those employed to examine 22 types of blood chemical ingredients. The discriminant, the positive or negative values of which refer to prognosis of survival or death, was mathematically derived from the improved CALD. This improved CALD allowed us to predict the prognosis at any time during the clinical course of AMI patients with a considerably good possibility of success. The rate of success 80% level for the surviving cases during the period from the first to the 14th hospitalization day, although it was below the 50% level in the early stage (the first to and second days) of hosoitalization.
