Bradykinin preconditioning improves the profile of cell survival proteins and limits apoptosis after cardioplegic arrest.
BACKGROUND We hypothesized that preconditioning the heart with bradykinin (BK) would improve the profile of antiapoptotic proteins and inhibit myocardial apoptosis. METHODS AND RESULTS Eighteen rabbit hearts were retrogradely perfused with Krebs-Henseleit buffer (KHB). Six control hearts were perfused with KHB for 90 minutes without cardioplegia ischemia. Six hearts were arrested for 30 minut...
متن کاملMyocardial interstitial glucose and lactate before, during, and after cardioplegic heart arrest.
The interstitial fluid of the human myocardium was monitored in 13 patients undergoing aortic valve and/or bypass surgery before, during, and after hypothermic potassium cardioplegia. The regulation of glucose and lactate was studied after sampling with microdialysis. The following questions were addressed. 1). Is the rate of transcapillary diffusion the limiting step for myocardial uptake of g...
متن کاملRemote ischaemic preconditioning reduces myocardial injury in patients undergoing cardiac surgery with cold-blood cardioplegia: a randomised controlled trial.
BACKGROUND Remote ischaemic preconditioning (RIPC) induced by brief ischaemia and reperfusion of the arm reduces myocardial injury in coronary artery bypass (CABG) surgery patients receiving predominantly cross-clamp fibrillation for myocardial protection. However, cold-blood cardioplegia is the more commonly used method world wide. OBJECTIVE To assess whether RIPC is cardioprotective in CABG...

Am J Physiol Heart Circ Physiol 279: H882–H888, 2000.—The effects of the potassium (K) channel opener pinacidil (Pin) on the coronary smooth muscle Ca-myosin light chain (MLC) phosphorylation pathway under hypothermic K cardioplegia were dete...
متن کاملConsistent Two to Four Degree Crystalloid Potassium Cardioplegia
_____________ _ The use of hypothermic crystalloid potassium cardioplegia in open heart surgery has been shown to be effective in arresting the heart and protecting it from ischemic injury during aortic crossclamping. A perfusion technique for the routine delivery of 2-4° centigrade (C) crystalloid potassium cardioplegia has been employed in 116 consecutive coronary artery bypass graft procedur...
