The report searches the impacts of serum creatinine phosphokinase (CPK) on diabetes, heart, and anaemia patients using a real data set of 299 subjects and a derived statistical modeling. It is shown that mean CPK is positively associated with AGE (P=0.0335) and ejection fraction (EFT) (P=0.0417), while it is negatively associated with their joint interaction effect (JIE) of AGE * EFT (P=0.0058). Mean CPK is negatively associated with serum creatinine (SCT) (P<0.0001), while it is positively associated with EFT (P=0.0417), and their JIE of EFT * SCT (P<0.0001). Mean CPK is indifferent to both the marginal effects of the subject's anaemia disease status (ADS) and platelets count (PLC), while it is negatively associated with their JIE of ADS * PLC ( P=0.0184). Mean CPK is negatively associated with SCT (P< 0.0001) and the subject's diabetes mellitus status (DMS) (P=0.0103), while it is positively associated with their JIE of DMS * SCT (P<0.0001). Variance of CPK is indifferent to DMS and the subject's smoking status (SMS), while it is negatively associated with their JIE of DMS * SMS (P=0.0023). Variance of CPK is positively associated with ADS (P=0.0229) and SEX (P= 0.0005), while it is negatively associated with their JIE of ADS * SEX (P=0.0212). CPK's variance is indifferent to PLC, and positively associated with ADS (P=0.0229), while it is negatively associated with their JIE of ADS * PLC (P=0.0400). It is observed that CPK is associated with diabetes, anaemia patients, cardiac factor EFT along with many other risk factors. These research outcomes may give much information for better treatment and research process.
