Clopidogrel Versus Adenosin in Non Urgent Percutaneous Coronary Intervention (PCI) — RACE  

Percutaneous Coronary Intervention Clinical Trial

Official title:
Randomized Comparison of Adenosin Intracoronary Infusion and Clopidogrel Pretreatment on Myonecrosis Occurence in Elective PCI

Clinical Trial Summary

Percutaneous coronary intervention (PCI) is associated with up to 30% incidence of myonecrosis, as reflected by elevation of cardiac enzymes in a successful procedure. Apart from side-branch occlusion, intimal dissection and coronary spasm, a possible aetiology of myonecrosis after PCI might be distal embolization of atherogenic materials from plaque disruption causing obstruction of blood flow at capillary level resulting in micro-infarction. Recent studies have suggested that pretreatment with adenosine in the cath lab and Clopidogrel and statins greater than 6 hours before may be associated with a reduction in infarct size after reperfusion therapy for acute myocardial infarction. Whether pretreatment with adenosine decreases the incidence of myonecrosis in patients undergoing non-urgent PCI is not fully known. The investigators propose that adenosine-induced hyperaemia can potentially ameliorate the deleterious effects of distal embolization associated with non-urgent PCI through dilatation of the microvasculature. Mechanistically, this may reduce capillary obstruction by facilitating the throughput passage of embolized platelet thrombi out to the venous end of the coronary circulation, thereby reducing the incidence of post-PCI myonecrosis. In this prospective, randomized, open-label study, the investigators evaluated the incidence of myonecrosis after non-urgent PCI with a treatment with intracoronary adenosine compared with pretreatment of loading dose of Clopidogrel 300/600 mg >/< 6 hours.
