OBJECTIVE Ischemic postconditioning (POC) by brief episodes of ischemia performed just at the time of reperfusion can reduce infarct size in animal models and clinical settings of percutaneous coronary intervention. However, the clinical applicability of postconditioning in cardiac surgery remains to be determined. We investigated the effect of(More)
BACKGROUND Postconditioning by brief episodes of ischaemia performed just at the time of reperfusion have been shown to reduce the size of infarcts in animal models, and in the clinical setting of percutaneous cardiac intervention. The clinical applicability of postconditioning in cardiac surgery remains to be determined. We investigated the effect of(More)
The postoperative course of cyanotic patients is generally more complicated than in acyanotic patients. The ischemic postconditioning provides protection from myocardial injury. We conducted a randomized trial to evaluate the clinical benefits of postconditioning in patients undergoing repair of tetralogy of Fallot. Ninety-nine patients with tetralogy of(More)
BACKGROUND Magnesium is often used to supplement cardioplegic solutions during cardiopulmonary bypass due to its cardioprotective effect during ischemia and reperfusion. The aim of this meta-analysis was to evaluate the effects of magnesium-supplemented cardioplegia versus an inactive (placebo) control cardioplegia on reducing cardiac injury after cardiac(More)
We previously found that remote ischemic perconditioning (RIPerc) was effective in attenuating myocardial injury during cardiac surgery. Given that microRNAs (miRs) act as an important player in ischemic/reperfusion (I/R) injury and apoptosis, this study aimed to investigate whether RIPerc reduces apoptosis in atrial myocardium and which apoptosis-related(More)
BACKGROUND Remote ischemic perconditioning (RIPerc) is a new alternative of remote ischemic conditioning and has not been well studied. RIPerc attenuates myocardial injury when applied during cardiac surgery. However, its protective effects on other organs remain unknown. MATERIALS AND METHODS Patients with rheumatic heart disease undergoing valve(More)
OBJECTIVE Ischemic postconditioning effectively minimizes the ischemic/reperfusion injury, and the large series of case reports on its protective effects in cardiac surgery are limited. A randomized trial was conducted to investigate the effect of ischemic postconditioning on cardiopulmonary protection in children undergoing cardiac surgery for tetralogy of(More)
OBJECTIVE To investigate the protective effects of hypoxic preconditioning (HPC) on myocardial cells, and to determine the protective mechanism. METHODS In the HPC model, the cells viability, productions of malondialdehyde (MDA), contents of ATP, lactate dehydrogenase (LDH), creatine kinase (CK), and expressions of intercellular adehesion molecule-1(More)
OBJECTIVE To summarize the experience of mitral vavuloplasty for mitral insufficiency in 53 patients. METHODS Between January 2001 and September 2006,53 patients (31 males and 22 females) with mitral insufficiency underwent mitral valve repair at our hospital. The mean age was (23.8+/-10.4) years, and the mean weight was (43+/-12) kg,including 29 cases of(More)
BACKGROUND Although the involvement of microRNAs (miRNAs) has been intensively studied in myocardial infarction, there is no report on the regulation of miRNAs by ischemic postconditioning in patients undergoing cardiac surgery. We aim to explore the regulation of miRNAs by ischemic postconditioning in double valve replacement. MATERIALS AND METHODS In(More)
