Beta-adrenoceptor-mediated responsiveness of human internal mammary artery
The internal mammary artery (IMA) is currently the preferred conduit for myocardial revascularization. However, pre-operative vasospasm and a hypoperfusion state during maximal exercise may limit its use as a bypass graft. The mechanism of spasm has not been clearly defined. Since β-adrenoceptor activation plays a major role in vasorelaxation, the present study was carried out to investigate th...

متن کاملManagement of Internal Mammary Artery Spasm
The article is dedicated to the management of internal mammary artery spasm intraand postoperatively based on the accumulated evidence in the literature. It provides stepwise decision algorithms for safely resolving the spasm and prevention of relapse. INTRODUCTION The left internal mammary artery (IMA) is the most widely used graft and is predominantly anastomosed to the left anterior descendi...
