OBJECTIVE: To evaluate whether liposomal prostaglandin E1 (lipo-PGE1) can decrease reperfusion no-reflow in a catheter-based porcine model of acute myocardial infarction (AMI).
METHODS: Twenty-two male Chinese mini-swines were randomized into three groups: six in a sham-operation group, and eight each in the control and lipo-PGE1 groups. The distal part of the left anterior descending coronary artery (LAD) in the latter two groups was completely occluded for 2 h, and then reperfused for 3 h. Lipo-PGE1 (1 μg/kg) was injected 10 min before LAD occlusion until reperfusion for 1 h in the lipo-PGE1 group. Hemodynamic data and proinflammatory cytokines were examined before AMI, 2 h after occlusion, and 1, 2, and 3 h after reperfusion. Myocardial contrast echocardiography (MCE) and double staining were performed to evaluate the myocardial no-reflow area (NRA).
RESULTS: Left ventricular systolic pressure and end-diastolic pressure significantly improved in the lipo-PGE1 group after reperfusion compared with the control group and also 2 h after AMI (P<0.05 for both). MCE and double staining both showed that lipo-PGE1 decreased reperfusion NRA after AMI (P<0.05, P<0.01). Lipo-PGE1 decreased serum interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) after myocardial infarction reperfusion (P<0.05 for both).
CONCLUSIONS: Lipo-PGE1 is cardioprotective in our porcine model of myocardial infarction reperfusion no-reflow, decreasing NRA and attenuating the inflammatory response.
