UNLABELLED Simvastatin can prevent cardiac remodelling after myocardial infarction, though the exact mechanisms are uncertain. Myocardial no-reflow is associated with progressive cardiac remodelling. However, it remains unknown whether post-infarction treatment with simvastatin can also reduce myocardial no-reflow for which suppression of adenosine triphosphate-sensitive K+ (K(ATP)) channel ope...
During global ischemia in isolated rat hearts, the development of contracture, due to irreversible myofilament sliding, causes reduction of left ventricle luminal volume. Also, a considerable area of the myocardium cannot be reperfused after 1 hour's global ischemia. The purpose of this study was to reduce myofilament sliding by placing a fluid-filled isovolumic balloon in the left ventricular ...
BACKGROUND We investigated myocardial perfusion dynamics after thrombolysis and its clinical implications. METHODS AND RESULTS We studied 39 patients with acute anterior myocardial infarction (AMI). Myocardial contrast echocardiography (MCE) was performed before and immediately after successful reflow with intracoronary injection of sonicated Ioxaglate. The average segmental score by two-dime...
It has been verified that glycoprotein IIb/IIIa inhibitor tirofiban can attenuate myocardial no-reflow. Myocardial no-reflow has been associated with alterations in endothelial junctions. In addition, ET-1 is an important mechanism for myocardial no-reflow. However, the effect of tirofiban on endothelial junctions and Endothelin-1 (ET-1) is unknown. Methods: Twenty-eight mini-swines were random...
BACKGROUND Ischemia/reperfusion injury may have deleterious short- and long-term consequences for cardiac allografts. The underlying mechanisms involve microvascular dysfunction that may culminate in primary graft failure or untreatable chronic rejection. METHODS AND RESULTS Here, we report that rat cardiac allograft ischemia/reperfusion injury resulted in profound microvascular dysfunction t...
