Abstract/OtherAbstract:
Forty-five pigs with acute coronary artery occlusions-low MI pulse sequence (CPS) to guide high MI (1.9 MI) pulses during infusion of platelet-targeted MBs or non-targeted MBs. Third group received no ultrasoundMB. All groups received pro-urokinase, heparin, and aspirin. Angiographic recanalization rates, resolution of ST elevation, and wall thickening were analyzed. Pigs receiving MB had more rapid replenishment of risk area (RA) (80% versus 40% for MB; p=0.03) and higher epicardial recanalization rates (53% versus 7% for pro-urokinase alone; p=0.01). Replenishment of contrast within RA with MB showed higher recanalization rates and higher rates of ST resolution (82% versus 21% for pro-urokinase alone; p=0.006). ST resolution occurred in six pigs (40%) with MB who did not have epicardial recanalization; five had recovery of wall thickening. Conclusions: IV MB with brief high MI DUS guided by CPS improves both epicardial recanalization rates and microvascular recovery.
