Key result
Postdilatation following stent implantation during primary percutaneous coronary intervention significantly increased the rate of final no-reflow compared to no postdilatation (22.2% vs. 9.3%) in STEMI patients.
Why the study?
Postdilatation improves stent expansion during PCI but may increase distal thromboembolization and microvascular injury in STEMI, leaving its benefit controversial.
Does adjunctive balloon postdilatation improve coronary blood flow and reduce inhospital mortality in patients undergoing primary PCI for STEMI?
Population
216 STEMI patients undergoing primary PCI
Comparison
Postdilatation vs no postdilatation following stent implantation
Design
Retrospective propensity score-matched study

Postdilatation was associated with higher no-reflow in STEMI primary PCI; leaves open whether to avoid routine use pending randomized trials.

Does adjunctive balloon postdilatation improve coronary blood flow and reduce inhospital mortality in patients undergoing primary PCI for STEMI?
Absolute Event Rate: 22.2% vs 9.3%
p-value: p=0.009
Adjunctive balloon postdilatation during primary PCI for STEMI is associated with an increased risk of angiographic no-reflow without a significant impact on inhospital mortality.
Şenöz et al. (2021) conducted a cohort in ST-segment elevation myocardial infarction (STEMI) (n=216). Postdilatation vs. No postdilatation was evaluated on Final no-reflow (TIMI 0-2) rate (p=0.009). Postdilatation following stent implantation during primary percutaneous coronary intervention significantly increased the rate of final no-reflow compared to no postdilatation (22.2% vs. 9.3%) in STEMI patients.
