Key result
Patients with STEMI and nonobstructive residual stenosis after thrombus aspiration had a significantly lower prevalence of multivessel disease compared to those with obstructive stenosis (15.1% vs 46.2%, P<0.001).
Why the study?
What are the clinical and angiographic predictors of nonobstructive residual stenosis after thrombus aspiration in patients with STEMI?

What are the clinical and angiographic predictors of nonobstructive residual stenosis after thrombus aspiration in patients with STEMI?
Absolute Event Rate: 15.1% vs 46.2%
p-value: p=<0.001
A significant proportion of STEMI patients have nonobstructive residual stenosis after thrombus aspiration, which is independently predicted by younger age and the absence of other vascular disease.
No takes yet. Share an insight, caveat, or question.
May signal lower atherosclerotic burden in STEMI after thrombus aspiration; leaves open whether this alters revascularization decisions.
Gonçalves et al. (2012) conducted a cohort in ST-elevation myocardial infarction (STEMI) (n=172). Nonobstructive residual stenosis (<50%) vs. Obstructive residual stenosis (≥50%) was evaluated on Multivessel disease (p=<0.001). Patients with STEMI and nonobstructive residual stenosis after thrombus aspiration had a significantly lower prevalence of multivessel disease compared to those with obstructive stenosis (15.1% vs 46.2%, P<0.001).
