Key result
Intracoronary epinephrine successfully reversed refractory no-reflow during primary PCI, significantly improving TIMI flow grade from 1.33 to 2.66 (p < 0.001) and restoring TIMI 3 flow in 75% of patients.
Why the study?
Does intracoronary epinephrine improve coronary flow in STEMI patients with refractory no-reflow after primary PCI?

No
Does intracoronary epinephrine improve coronary flow in STEMI patients with refractory no-reflow after primary PCI?
Absolute Event Rate: 2.66% vs 1.33%
p-value: p=<0.001
Intracoronary epinephrine safely and effectively improves angiographic coronary flow in STEMI patients experiencing refractory no-reflow during primary PCI.
No takes yet. Share an insight, caveat, or question.
May support intracoronary epinephrine for refractory no-reflow; hypothesis-generating and requires randomized confirmation before practice change.
Aksu et al. (2015) conducted an observational in Refractory no-reflow after primary percutaneous coronary intervention for STEMI (n=12). Intracoronary epinephrine vs. Baseline (pre-epinephrine) was evaluated on TIMI flow grade (TFG) (p=<0.001). Intracoronary epinephrine successfully reversed refractory no-reflow during primary PCI, significantly improving TIMI flow grade from 1.33 to 2.66 (p < 0.001) and restoring TIMI 3 flow in 75% of patients.
