Brief summary
we hypothesized that periprocedural treatment with intravenous lipo-PGE1 may reduce myocardial injury and improve clinical outcomes in patients undergoing PCI.
Detailed description
Ever since the inception of percutaneous coronary intervention (PCI), it has been apparent that some myocardial injury was often associated with the procedure, and even asymptomatic minor post-procedural myocardial necrosis does have an important prognostic signification. The possible mechanisms of periprocedural myocardial injury were often attributed to distal embolisation of atheromatous material during the procedure, occlusion of minute side branches, occlusive dissection or no-reflow. Prostaglandin E1 incorporated in lipid microspheres (lipo-PGE1) is a new galenic form of PGE1, with PGE1 incorporated into soybean oil microspheres 0.2 micron in diameter, using lecithin as surfactant. This drug preparation can protect PGE1 against inactivation in the lung and has targeting effect to tissues injured by arterial occlusion. It was shown in the experiments that, by the pharmacological effects such as improving endothelial function, dilating coronary and systemic microvessels, inhibiting platelet aggregation and reducing ischemia-reperfusion injury, lipo-PGE1 had a more marked protective effect in arterial occlusive tissue injury and a more potent platelet aggregation inhibitory effect than free PGE1. Clinical studies have demonstrated that lipo-PGE1 is a very valuable agent for the treatment of peripheral vascular disorders and diabetic neuropathy.
Interventions
DRUGlipo-PGE1
those in the PGE1 group received additional 20 micrograms/day of lipo-PGE1 intravenously, starting at least 24 hours before PCI and continuing for 5 days
