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...

in patients requiring coronary artery bypass grafting (cabg), usually at least one of the internal mammary arteries is used. this study evaluates the degree of atherosclerotic involvement of the internal mammary artery (ima) in patients undergoing cabg. during two months period, 79 patients (66 male and 13 female with a medium age of 58 years) undergoing myocardial revascularization had a biops...

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.

background the prevalence of chronic postoperative pain after cardiac surgery has been reported from 17% to 56%. objectives we aimed to compare the prevalence of postoperative pain between patients who had undergone cabg using the internal mammary artery (ima) and those who had undergone other cardiac surgeries including cabg using the saphenous vein or cardiac valvular surgeries. patients and ...

  Among the present classes of calcium channel blockers, dihydropyridine derivatives are widely used in the therapy of hypertension, angina pectoris and the other cardiovascular diseases. Since the prototype of dihydropyridine derivatives, nifedipine, does not have the optimum pharmacokinetic and pharmacodynamic characteristics, several attempts have been made to synthesize other drugs in this ...

I read with interest the article in the April 2012 edition by Grau et al. I congratulate Grau et al. [1] for an excellent study. It will be interesting to know how both internal mammary arteries were used—either in situ or as y graft. In spite of the established superiority of left internal mammary artery graft, the use of the bilateral internal mammary artery has not gained popularity. In rece...

AIM The left internal mammary artery is the graft of choice for coronary artery bypass surgery. The necessity for preoperative internal mammary artery angiography is still controversial. We designed a prospective left internal mammary angiography for evaluating the risk of stenosis in the left internal mammary and subclavian artery, and the risk and the necessity for pre-operative internal mamm...

BACKGROUND Standard coronary artery bypass graft surgery uses a single internal mammary artery and supplemental vein or radial artery grafts. Several observational studies have suggested a survival benefit with two internal mammary artery grafts compared to a single internal mammary artery graft, but this has not been tested in a randomised trial. The Arterial Revascularisation Trial is a Medic...
