Key result
Significant coronary artery stenosis (>70%) was associated with worse stress-induced myocardial perfusion defects compared to intermediate stenosis (40-69%), with a median Summed Stress Score of 8.0 versus 4.0.

Zavadovsky et al. (2017) conducted a cross-sectional in Stable coronary artery disease (n=102). Significant coronary artery stenosis (>70%) vs. Intermediate coronary artery stenosis (40-69%) was evaluated on Summed Stress Score (SSS) (p=0.004). Significant coronary artery stenosis (>70%) was associated with worse stress-induced myocardial perfusion defects compared to intermediate stenosis (40-69%), with a median Summed Stress Score of 8.0 versus 4.0.
