Total and indirect effects of sPAT on the association between mental stress-induced ischemia and worsening executive function. Indirect effect= 0.35*0.17. This pathway accounted for 18.2% of the total effect (indirect effect/(indirect effect + direct effect) x100).
Model adjusted for demographics (age, sex, race, and education), clinical variables (body mass index, hypertension, hyperlipidemia, diabetes mellitus, smoking history, prior myocardial infarction, and heart failure) and medication use (aspirin, statin, angiotensin-converting enzyme inhibitor, and beta-blockers).
