BACKGROUND: Acute renal dysfunction (ARD) is common after cardiac surgery with cardiopulmonary bypass (CPB). CPB results in a sudden systemic inflammatory response. Systemic and local pro-inflammatory cytokines synthesis has been linked with sub-clinical renal injury, especially tubular lesions. Therefore, we sought to assess the systemic synthesis pro-inflammatory cytokines and its ...

In patients with coronary artery disease, the need for more accurately defined treatment recommendations based on the distribution of atherosclerotic disease has given rise to multiple trials designed to evaluate the efficacy of medical therapy versus percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). To clarify these treatment ...
Bulcao Christian F - - 2008
BACKGROUND: Cardiopulmonary bypass (CPB) and cardioplegic arrest during cardiac surgery leads to desensitization of myocardial beta-adrenergic receptors (beta-ARs). Impaired signaling through this pathway can have a detrimental effect on ventricular function and increased need for inotropic support. The mechanism of myocardial beta-AR desensitization during cardiac surgery has not been defined. ...

BACKGROUND: Angiotensin-converting enzyme (ACE) inhibitors confer renal protection in different clinical settings. No final conclusions are available on the renal benefits of ACE inhibitors after coronary artery bypass grafting (CABG). Because ACE inhibitors decrease glomerular perfusion pressure, they may exacerbate kidney injury during cardiopulmonary bypass (CPB)-related hypoperfusion. We evaluated the ...
