Hyperchloremia is associated with poor renal outcome after coronary artery bypass grafting

Abstract Background Hyperchloremia is associated with the risks of several morbidities and mortality. However, its relationship with acute kidney injury (AKI) and end-stage renal disease (ESRD) in patients undergoing coronary artery bypass grafting (CABG) remains unresolved. Methods A total of 2977 patients undergoing CABG between 2003 and 2015 were retrospectively reviewed from two tertiary hospitals. Patients were categorized by serum chloride levels into normochloremia (95–105 mmol/L), mild hyperchloremia (106–110 mmol/L), and severe hyperchloremia (> 110 mmol/L). The odds ratios (ORs) for AKI and hazard ratios (HRs) for ESRD were calculated after adjustment for multiple covariates. The death-adjusted risk of ESRD was additionally evaluated. Results Postoperative AKI occurred in 798 patients (26.5%). The hyperchloremia group had a higher risk of AKI than the normochloremia group, wherein the risk was incremental depending on the severity of hyperchloremia, as follows: ORs were 1.26 (1.06–1.51) and 1.95 (1.52–2.51) in the mild and severe hyperchloremia groups, respectively. During a median period of 7 years (maximum 15 years), 70 patients (2.3%) had ESRD. The severe hyperchloremia group was at an elevated risk of ESRD compared with the normochloremia group, with an HR of 2.43 (1.28–4.63). Even after adjusting for the competing risk of death, hyperchloremia was associated with the risk of ESRD. Conclusions Preoperative hyperchloremia is associated with poor renal outcomes such as AKI and ESRD after CABG. Accordingly, serum chloride should be monitored in patients undergoing CABG.

Risk Of Death

Abstract Purpose To assess the prevalence of frailty in the preoperative period and to evaluate its effect on the risk of complications and adverse outcomes in patients undergoing coronary artery bypass grafting (CABG). Methods 303 patients undergoing preoperative management for elective primary CABG were recruited in the study. The study cohort was divided into three groups depending on the PRISMA-7 scores suggesting the presence or absence of frailty and the presence of prefrailty. Statistical analysis was performed using the commercially available software package STATISTICA 8.0.360.0 for Windows (StatSoft, Inc., USA) and SPSS Statistics v. 17.0.0. Results 46 (15%) patients had frailty, while 49 (16%) patients were diagnosed with prefrailty. 208 (69%) patients did not have any signs of frailty. All three groups had significant age differences, therefore only elderly patients aged of 67.0±6.5 years with frailty were allocated for subsequent analysis (prefrailty group - 62.3±7.4 years old, patients without frailty - 60.0±7.7 years, p=0.003). Patients with frailty or prefrailty more often suffered from diabetes mellitus (patients without frailty - 19.2%, prefrailty group - 30.6% and frailty group - 28.3%, p=0.05), arterial hypertension (69.2%, 93.9% and 95.7%, respectively, p<0.001), atrial fibrillation or flutter (7.2%, 14.3% and 19.6%, respectively, p=0.03), chronic heart failure class 3–4 (7.2%, 10.2% and 8.7%, respectively, p=0.002), and peripheral arterial disease (22.6%, 38.8% and 58.7%, respectively, p<0.001). Three groups were comparable in main clinical and demographic parameters. There were no significant differences found in the incidence of postoperative atrial fibrillation or flutter (15.9%, 8.2% and 6.5%, respectively, p=0.07) and infections (1.9%, 0% and 4.3%, respectively, p=0.640). The incidence of myocardial infarction in the intra- and early postoperative period after CABG did not differ significantly between the groups (0.5%, 2% and 0%, respectively, p=0.328) as well as the incidence of stroke (2.4%, 2% and 0%, respectively, p=0.640). Patients with frailty and prefrailty had significantly higher cerebrovascular and cardiovascular mortality compared to those without frailty (8.2%, 2.2% and 0.5%, respectively, p=0.001). Conclusion Almost 15% of patients referred to CABG suffered from frailty. The presence of prefrailty or frailty increases the risk of death in the early postoperative period after CABG.

Objective Epiaortic ultrasound (EU) reliably reveals ascending aortic atherosclerosis (AAA), allowing strategies to minimize the risk of embolization or plaque disruption during coronary artery bypass grafting. Our objective was to delineate if EU-guided intervention improved outcomes. Methods Patients undergoing coronary artery bypass grafting (2004–2007) were categorized by EU grade (grade 1–2 [mild] vs. 3–5 [moderate/severe]) and the use of an aortic clamp. A propensity score estimated probability of clamp use was based on 45 risk factors. Multiple logistic regression models measured the association between outcomes—death, stroke, myocardial infarction, and major adverse cardiac and cerebrovascular events (MACCE)—and the primary variables (grade and clamp use), adjusted for propensity score. Results Grade was available in 4278 patients. Patients with grade 3 to 5 AAA had an increased risk of death (adjusted odds ratios (AOR) 3.11; P < 0.001), stroke (AOR 2.12; P < 0.001), and MACCE (AOR 2.58; P < 0.001). Aortic clamping (any clamp, all grades) led to a higher risk of stroke (AOR 2.77; P = 0.032). EU altered aortic manipulation in 530 patients (12.4%). In this group, patients with high grade aortas had similar rates of death, stroke or MACCE, when compared with patients with low-grade aortas. Conclusions EU alters surgical strategy. Patients with grade 3 to 5 AAA are at increased risk of death, stroke, and MACCE compared with patients with grade 1 to 2 AAA. Clamping the aorta (any grade) increases the risk for stroke. Aortic clamping should be avoided in patients with grade 3 to 5 AAA, but EU may minimize morbidity and mortality if a clamp must be used.
