Parameter estimates of the risk equations for first and second AMI and HF events.

All covariates are significant at the 5% level.Weibull proportional hazards regression with the Prentice, Williams, and Peterson gap time model was used for estimation.Abbreviations: HF, heart failure; AMI, acute myocardial infarction; TC/HDL, total to HDL cholesterol ratio.a. Significant at the 10% level, but significant interaction with LDL;b. applied as splines in the equation;c. history of event before diagnosis of type 2 diabetes;d. HF before first AMI.
