Brief Summary
Primary percutaneous coronary intervention (PPCI) is the gold standard of treatment of ST segment elevation myocardial infarction (STEMI).Slow flow / no-reflow phenomenon following PPCI in STEMI patients has been a serious and common complication that closely related to the incidence of major adverse cardiovascular events (MACE) and affected patients' prognosis. No reflow is a multi-factorial phenomenon. And its preventive and therapeutic effects are not satisfactory. This prospective randomized controlled study aimed to compare favorable effects of Nitroprusside versus Tirofiban on the prevention of slow flow / no-reflow phenomenon during PPCI.

Outcome Measures
Primary Outcomes (7)
Coronary artery flow using thrombolysis in myocardial infarction (TIMI) flow grade after stent implantation
Grade 0, no myocardial blush or contrast density; grade 1, minimal myocardial blush or contrast density; grade 2, moderate myocardial blush or contrast density but less than that obtained during angiography of a contralateral or ipsilateral noninfarct-related coronary artery; grade 3, normal myocardial blush or contrast density comparable with that obtained during angiography of a contralateral or ipsilateral noninfarct-related coronary artery.
1 minute after stent implantation
Coronary artery flow using TIMI flow grade after balloon dilatation
Grade 0, no myocardial blush or contrast density; grade 1, minimal myocardial blush or contrast density; grade 2, moderate myocardial blush or contrast density but less than that obtained during angiography of a contralateral or ipsilateral noninfarct-related coronary artery; grade 3, normal myocardial blush or contrast density comparable with that obtained during angiography of a contralateral or ipsilateral noninfarct-related coronary artery.
1 minute after balloon dilatation
Coronary TIMI frame count after stent implantation
A continuous measurement assessing flow in the epicardial arteries.
1 minute after stent implantation
Coronary TIMI frame count after balloon dilatation
A continuous measurement assessing flow in the epicardial arteries.
1 minute after balloon dilatation
Slow flow / no-reflow phenomenon after stent implantation
Slow flow phenomenon means delayed progression or lack of contrast medium through the coronary tree.
1 minute after stent implantation
Slow flow / no-reflow phenomenon after balloon dilatation
Slow flow phenomenon means delayed progression or lack of contrast medium through the coronary tree.
1 minute after balloon dilatation
ECG ST-segment fall more than 50%
The extent of ST segment elevation was reduced by more than 50%
in 2 hours post-PCI
Secondary Outcomes (1)
Main adverse cardiovascular and cerebrovascular events (MACCE)
at 1 day post-PCI, at follow up of 1, 3, 6,12 months post-PCI
Study Arms (3)
Nitroprusside group
EXPERIMENTALAfter coronary target vessel blood flow recovery by thrombus aspiration or/and balloon angioplasty (diameter ≤ 2.0mm), intracoronary infusion of Nitroprusside Sodium via guide-catheter was performed. Then repeated administration of Nitroprusside Sodium was done prior to coronary stent implantation or post dilatation.
Tirofiban group
EXPERIMENTALAfter coronary target vessel blood flow recovery by thrombus aspiration or/and balloon angioplasty (diameter ≤ 2.0mm), intracoronary infusion of Tirofiban Hydrochloride via guide-catheter was performed.
Control group
PLACEBO COMPARATORAfter coronary target vessel blood flow recovery by thrombus aspiration or/and balloon angioplasty (diameter ≤ 2.0mm), intracoronary infusion of heparinized saline via guide-catheter was performed.
Interventions
Intracoronary infusion 50\~100μg each time (repeated)
Intracoronary infusion 10μg/kg for single time
Intracoronary infusion 2ml for single time
