  Purpose

The occurrence of no-reflow phenomenon after recanalization of the infarct related artery in acute myocardial infarction is described in up to 40% of cases. This event is associated with a worse prognosis at follow up and an unfavourable left ventricular remodelling . Two main pathogenetic mechanisms cause no-reflow: distal embolization and ischemia-reperfusion injury.

Due to the multifactorial pathogenesis of no-reflow during acute MI a combined mechanic and pharmacologic approach is believed to offer a better solution for achieving optimal microvascular reperfusion. Thus, in this randomized study we will assess the effect of nitroprusside or adenosine in adjunct to current best therapy (thrombus aspiration and IIb-IIIa antagonists) for ST elevation MI using ST segment resolution on standard 12 leads ECG as primary endpoint of myocardial reperfusion.

Primary Outcome Measures:
  • Rate of major adverse cardiac events [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]

Enrollment: 240
Study Start Date: January 2008
Study Completion Date: September 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
Patients will receive intravenous administration of abciximab prior to PCI. After wire crossing, thrombus aspiration will be performed. The device will removed outside the body, flushed with saline and subsequently reintroduced in the culprit vessel beyond the occlusion site and intracoronary drugs will be selectively administered.
Drug: adenosine
Adenosine (80 mcg as fast bolus followed by 2 mg given in 33cc of saline in 2 minutes as slow bolus)
Active Comparator: 2
Patients will receive intravenous administration of abciximab prior to PCI. After wire crossing, thrombus aspiration will be performed. The device will removed outside the body, flushed with saline and subsequently reintroduced in the culprit vessel beyond the occlusion site and intracoronary drugs will be selectively administered.
Drug: nitroprusside
Nitroprusside (60 mcg as fast bolus followed by 100 mcg given in 33cc of 5% glucose in 2 minutes as slow bolus)
Placebo Comparator: 3
Patients will receive intravenous administration of abciximab prior to PCI. After wire crossing, thrombus aspiration will be performed. The device will removed outside the body, flushed with saline and subsequently reintroduced in the culprit vessel beyond the occlusion site and intracoronary drugs will be selectively administered
Drug: placebo
33 cc of heparinized saline given in 2 minutes as slow bolus
