DO ALL SPECT APPROPRIATENESS CRITERIA PREDICT LONG-TERM CLINICAL OUTCOMES? A 3-YEAR FOLLOW-UP STUDY

SPECT Appropriateness Criteria (AC) has been established for quality of care since 2005. Our prior study (JACC 2013;61:10S) showed AC predictive power in 1 year follow-up. This study sought to evaluate the effectiveness of appropriate (A) vs. inappropriate (I) AC to predict MACE in 3-year follow-up
