Arm Description

After 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.

After 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.

After 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.

Outcomes

Primary Outcome Measures

Coronary artery flow using thrombolysis in myocardial infarction (TIMI) flow grade
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.
Coronary TIMI frame count
A continuous measurement assessing flow in the epicardial arteries.
Slow flow / no-reflow phenomenon
Slow flow phenomenon means delayed progression or lack of contrast medium through the coronary tree.

Secondary Outcome Measures

Main adverse cardiovascular and cerebrovascular events (MACCE)
Death, Cardiac death, Rehospitalization (Heart failure) , Non-fatal myocardial infarction, Target vessel myocardial infarction, Target lesion revascularization, Target vessel revascularization, Ischemic-driven revascularization, Stent thrombosis, Bleeding, Cerebrovascular events, etc.

5. Study Description

Brief Summary
Elective percutaneous coronary intervention (EPCI) is the common treatment of ST segment elevation myocardial infarction (STEMI).Slow flow / no-reflow phenomenon following EPCI 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 EPCI.
