HR, Hazard ratio; CI, confidence intervals; IHD, ischemic heart disease; hs-CRP, high-sensitivity C-reactive protein; RWMA, regional wall motion abnormality; LVH, left ventricular hypertrophy; LVEF, left ventricular ejection fraction; SSS, summed stress score.
* Adjusted with age, gender, diabetes, LV ejection fraction, and reversible perfusion defect.
** Adjusted with age, gender, diabetes, LV ejection fraction, and any type of perfusion defect (reversible, fixed, and mixed).
