All-cause mortality and non-fatal MI were the primary end points. The association of the primary end point with ischaemia severity and CFVR-LAD was assessed, after multivariable adjustment for all other significant clinical and imaging variables, including anatomic CAD severity by the modified Duke Prognostic Index. The primary end point occurred in 767 (24%) patients (death in 409 and non-fatal MI in 375 patients) during a median follow-up of 42 months. Multivariable Cox regression analyses indicated that, among other significant variables, anatomic CAD severity, reversible ischaemia, and CFVR-LAD were all independently associated with the primary end point; reversible ischaemia was also associated with subsequent MI, while CFVR-LAD with mortality, independent of anatomic CAD severity.<\/jats:p>\n               <\/jats:sec>\n
