Key result
Larger fibrofatty volume over the entire lesion length was the only independent predictor of slow flow during primary PCI for acute myocardial infarction (beta 0.359; 95% CI 0.002-0.012; P=0.006).

Fibrofatty volume may predict slow flow in primary PCI; hypothesis-generating and should not change practice without prospective validation.

Does plaque composition assessed by IVUS-VH predict slow flow in patients undergoing primary PCI for acute myocardial infarction?
Effect estimate: beta 0.359 (95% CI 0.002-0.012)
p-value: p=0.006
Larger fibrofatty plaque volume assessed by IVUS-VH is an independent predictor of the slow flow phenomenon during primary PCI for acute myocardial infarction.
Bae et al. (2008) conducted an observational in Acute myocardial infarction (n=57). Larger fibrofatty volume vs. Smaller fibrofatty volume was evaluated on Slow flow during primary PCI (≤ TIMI grade 2) (beta 0.359, 95% CI 0.002-0.012, p=0.006). Larger fibrofatty volume over the entire lesion length was the only independent predictor of slow flow during primary PCI for acute myocardial infarction (beta 0.359; 95% CI 0.002-0.012; P=0.006).
