Standard covariates=age, male sex, obesity, education level, coronary risk factors (hypertension, dyslipidaemia, diabetes mellitus).
Model 1=standard covariates+previous MI.
Model 2=standard covariates+previous PCI.
BMI, body mass index; MI, myocardial infarction; PCI, percutaneous coronary intervention.
