Why the study?
Does pre-PCI index of microcirculatory resistance (IMR) predict periprocedural myocardial infarction in patients undergoing elective PCI?
Population
50 consecutive patients undergoing elective percutaneous coronary intervention of a single lesion in the…
Design
Cohort
Follow-up
periprocedural
Key result
Pre-PCI index of microcirculatory resistance ≥27 U was independently associated with a 23-fold increased risk of developing periprocedural MI (OR 22.7; 95% CI 3.8-133.9).

May inform periprocedural MI risk stratification before elective PCI; leaves open whether IMR-guided interventions improve outcomes.

Does pre-PCI index of microcirculatory resistance (IMR) predict periprocedural myocardial infarction in patients undergoing elective PCI?
Odds Ratio: 22.7 (95% CI 3.8–133.9)
p-value: p=0.003
Pre-PCI measurement of the index of microcirculatory resistance (IMR) strongly predicts the risk of periprocedural myocardial infarction during elective PCI.
Ng et al. (2012) conducted an observational in Elective percutaneous coronary intervention (n=50). Pre-PCI index of microcirculatory resistance (IMR) ≥27 U vs. Pre-PCI IMR <27 U was evaluated on Periprocedural myocardial infarction (OR 22.7, 95% CI 3.8-133.9, p=0.003). Pre-PCI index of microcirculatory resistance ≥27 U was independently associated with a 23-fold increased risk of developing periprocedural MI (OR 22.7; 95% CI 3.8-133.9).
