Key result
Suboptimal post-PCI TIMI flow linked to ~22-point higher in-hospital MACE rate.
Why the study?
TIMI flow grade after primary PCI in acute STEMI patients has significant implications for clinical outcomes, but its relation to in-hospital complications and risk factors needed further study.

Supports post-PCI TIMI flow for in-hospital risk stratification; leaves open whether optimization reduces MACE.
Tamrakar et al. (2021) conducted an observational in Acute ST-elevation myocardial infarction (STEMI) (n=93). Suboptimal TIMI flow (≤ 2) vs. TIMI flow = 3 was evaluated on Major adverse cardiac events (MACE) during hospitalization (p=0.008). Suboptimal post-procedural TIMI flow (≤ 2) was associated with a significantly higher rate of in-hospital major adverse cardiac events (48% vs 26%, p=0.008) compared to TIMI 3 flow.
