Impact of mild preoperative renal insufficiency on in-hospital and long-term outcomes after off-pump coronary artery bypass grafting: a retrospective propensity score matching analysis.

Background: Mild preoperative renal insufficiency is not rare in patients receiving isolated off-pump coronary artery bypass grafting surgery (OPCAB) surgery. However, there is less study aimed to evaluate the impact of mild preoperative renal insufficiency on in-hospital and follow-up outcomes after isolated OPCAB surgery. This single-centre, retrospective propensity score matching study aimed to evaluate the impact of mild preoperative renal insufficiency on in-hospital and long-term outcomes after first isolated OPCAB surgery.

Impact of smoking on early clinical outcomes in patients undergoing coronary artery bypass grafting surgery.

Background: To evaluate the impact of persistent smoking versus smoking cessation over one month prior to surgery on early clinical outcomes in Chinese patients undergoing isolated coronary artery bypass grafting (CABG) surgery in a retrospective study.

Methods: The peri-operative data of consecutive well-documented patients undergoing isolated CABG surgery from January 2007 to December 2013 were investigated and retrospectively analyzed. All included patients were divided into either a non-smoking group or a smoking group according to preoperative smoking records.

Risk factors for late right ventricular systolic dysfunction in pediatric patients with repaired tetralogy of Fallot.

To evaluate independent risk factors for late right ventricular systolic dysfunction after correction of Tetralogy of Fallot (TOF) in a single-centre, retrospective and observational clinical trial.Patients less than 3 years of age who underwent correction of TOF and subsequently routine clinical follow-up of more than 36 months were included in this study and were divided either into an experimental group (right ventricular systolic dysfunction) or a control group (normal right ventricular systolic function) according to the tricuspid annular peak systolic velocity (TAPSV) value measured by pulsed wave-tissue Doppler imaging (pulsed wave-TDI). The relevant data of all selected patients were investigated and analyzed.

Protective effects of tight glucose control during cardiopulmonary bypass on myocardium in adult nondiabetic patients undergoing valve replacement.

Background: In this study, we aimed to evaluate the protective effect of tight glucose control during cardiopulmonary bypass on myocardium in adult nondiabetic patients undergoing isolated aortic valve replacement in a prospective and randomized trial.

Methods: Sixty-five adult nondiabetic patients undergoing selective isolated aortic valve replacement were enrolled and randomly assigned to an insulin group (patients received a continuous insulin infusion during surgery; n = 33) or a control group (patients were not administered insulin unless their blood glucose level exceeded 200 mg/dL; n = 32). Cardiac troponin I was assayed preoperatively, and then at 2, 6, 12, 24, and 48 hours after aortic cross-declamping.

Expression changes of ionic channels in early phase of cultured rat atrial myocytes induced by rapid pacing.

Background: Recent studies have demonstrated that atrial electrical remodeling was an important contributing factor for the occurrence, persistence and maintenance of atrial fibrillation. The expression changes of ionic channels, especially L-type calcium channel and potassium channel Kv4.3, were the important molecular mechanism of atrial electrical remodeling.

Risk factors for pulmonary complications following cardiac surgery with cardiopulmonary bypass.

Background: Pulmonary complications following cardiac surgery with cardiopulmonary bypass (CPB) are often associated with significant morbidity and mortality. However, few reports have focused on evaluating intra- and post-operative independent risk factors for pulmonary complications following cardiac surgery with CPB. This study aimed to evaluate peri-operative independent risk factors for postoperative pulmonary complications through investigating and analyzing 2056 adult patients undergoing cardiac surgery with CPB.

Timing of continuous veno-venous hemodialysis in the treatment of acute renal failure following cardiac surgery.

The purpose was to study optimum timing of continuous veno-venous hemodialysis (CVVHD) for acute renal failure (ARF) after cardiac surgery. CVVHD was performed in two groups [elapsed time between urine output (UO) <0.5 ml/kg/h and dialysis of no more than 12 h in group A and >12 h in group B] with a total of 58 adult patients.

Risk factors for late extubation after coronary artery bypass grafting.

Objective: To evaluate the independent risk factors for late extubation after coronary artery bypass grafting (CABG).

Methods: Preoperative, intraoperative, and postoperative characteristics of patients undergoing isolated CABG between June 2005 and June 2008 at the Tongji Hospital were retrospectively analyzed. Elapsed time between CABG and extubation of more than 8hours was defined as late extubation.

[Opportunity for treatment of acute renal failure after cardiac vascular operation using continuous blood purification].

Objective: To evaluate the effect and timing of continuous blood purification (CBP) in treatment of acute renal failure (ARF) following cardiac-vascular surgery.

Methods: Twenty-five patients with ARF following cardiac-vascular surgery were divided into systematic inflammatory response syndrome (SIRS) Group (n = 13) and multiple organ dysfunction syndrome (MODS) Group (n = 12) according to the illness state prior to CBP and were divided into Group A (n = 5, with the APACHEIII score prior to CBP 90). All of the 25 patients underwent continuous veno-venous hemofiltration (CVVH).

Study on the risk factors of postoperative hypoxemia in patients undergoing coronary artery bypass grafting.

Background: To investigate 576 patients undergoing coronary artery bypass grafting (CABG) and to evaluate independent high risk factors of postoperative hypoxemia following CABG.

Methods And Results: The pre-, intra-, and post-operative materials in patients who had CABG performed on them from March 2004 to March 2008 in our hospital were analyzed retrospectively. The relative factors of postoperative hypoxemia were tested through descriptive analysis and logistic regression, and the independent risk factors were obtained.
