Fig. 2From: Efficacy and safety of intracoronary prourokinase during percutaneous coronary intervention in treating ST-segment elevation myocardial infarction patients: a randomized, controlled studyCoronary physiology assessments results. The IMR in intracoronary prourokinase group was reduced compared with control group (a), while no difference of CFR (b) or FFR (c) was found between the two groups. Comparison between the two groups was determined by t-test. P-value < 0.05 was considered as statistically significant. IMR, index of microcirculatory resistance; CFR, coronary flow reserve; FFR, fractional flow reserveBack to article page
