NCT03406819

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

EXPERIMENTAL

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.

Drug: Nitroprusside Sodium

Tirofiban group

EXPERIMENTAL

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.

Drug: Tirofiban Hydrochloride

Control group

PLACEBO COMPARATOR

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.

Drug: Heparinized saline

Interventions

Intracoronary infusion 50\~100μg each time (repeated)

Also known as: Experimental-1 group
Nitroprusside group

Intracoronary infusion 10μg/kg for single time

Also known as: Experimental-2 group
Tirofiban group

Intracoronary infusion 2ml for single time

Also known as: Control group
Control group
