Preoperative arterial lactate and outcome after surgery for type A aortic dissection: The ERTAAD multicenter study. Heliyon 2023; 9:e20702. [PMID: 37829811 PMCID: PMC10565766 DOI: 10.1016/j.heliyon.2023.e20702] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 09/25/2023] [Accepted: 10/04/2023] [Indexed: 10/14/2023] Open
Abstract
Background Acute type A aortic dissection (TAAD) is associated with significant mortality and morbidity. In this study we evaluated the prognostic significance of preoperative arterial lactate concentration on the outcome after surgery for TAAD. Methods The ERTAAD registry included consecutive patients who underwent surgery for acute type A aortic dissection (TAAD) at 18 European centers of cardiac surgery. Results Data on arterial lactate concentration immediately before surgery were available in 2798 (71.7 %) patients. Preoperative concentration of arterial lactate was an independent predictor of in-hospital mortality (mean, 3.5 ± 3.2 vs 2.1 ± 1.8 mmol/L, adjusted OR 1.181, 95%CI 1.129-1.235). The best cutoff value preoperative arterial lactate concentration was 1.8 mmol/L (in-hospital mortality, 12.0 %, vs. 26.6 %, p < 0.0001). The rates of in-hospital mortality increased along increasing quintiles of arterial lactate and it was 12.1 % in the lowest quintile and 33.6 % in the highest quintile (p < 0.0001). The difference between multivariable models with and without preoperative arterial lactate was statistically significant (p = 0.0002). The NRI was 0.296 (95%CI 0.200-0.391) (p < 0.0001) with -17 % of events correctly reclassified (p = 0.0002) and 46 % of non-events correctly reclassified (p < 0.0001). The IDI was 0.025 (95%CI 0.016-0.034) (p < 0.0001). Six studies from a systematic review plus the present one provided data for a pooled analysis which showed that the mean difference of preoperative arterial lactate between 30-day/in-hospital deaths and survivors was 1.85 mmol/L (95%CI 1.22-2.47, p < 0.0001, I2 64 %). Conclusions Hyperlactatemia significantly increased the risk of mortality after surgery for acute TAAD and should be considered in the clinical assessment of these critically ill patients.

Abstract
Background Acute type A aortic dissection (ATAAD) is associated with high mortality. Previous studies found that maintaining a high level of oxygen delivery (DO2) could decrease the postoperative mortality, but the minimum threshold of DO2 remained unclear. The present study aimed to investigate the relationship between maintaining intraoperative DO2 ≥280 mL/(min·m2) and the 90-day postoperative mortality of ATAAD patients. Methods The clinical data of 178 ATAAD patients who underwent Sun's procedure in our center from January 2018 to July 2022 were retrospectively analyzed in the present cohort study. The included patients were divided into hypoxic group [DO2 <280 mL/(min·m2)] and normoxic group [DO2 ≥280 mL/(min·m2)]. The primary endpoint was the 90-day all-cause mortality, and the secondary endpoints were postoperative mechanical ventilation time, the application of continuous renal replacement therapy (CRRT), brain complications, and other postoperative complications. Results Among all the patients, a total of 23 patients died 90 days postoperatively. Compared with the hypoxic group, blood flow, hematocrit (HCT), DO2, and DO2/VO2 ratio during cardiopulmonary bypass (CPB) were significantly higher, while the need for CRRT and the 90-day mortality were significantly lower in the normoxic group. The median follow-up time was 4 months. Kaplan-Meier curve indicated that the survival rate of ATAAD patients in the normoxic group was significantly higher. Univariate cox regression analysis demonstrated that 90-day mortality was reduced by 72.1% in the normoxic group. Conclusions Maintaining DO2 ≥280 mL/(min·m2) during CPB by increasing CPB flow and HCT level is associated with decreased 90-day mortality of ATAAD patients.

Abstract
OBJECTIVE To analyze the clinical characteristics of patients with overweight acute type A aortic dissection, and to explore the risk factors of acute kidney injury in patients with overweight acute type A aortic dissection. METHODS From March 2019 to February 2022, the clinical data of 71 patients with acute type a aortic dissection diagnosed by CTA and undergoing surgical treatment with BMI > 24 in the First People's Hospital of Yunnan Province were retrospectively analyzed, and analyzed by univariate and logistic multivariate analysis methods. RESULTS The mean BMI of all included patients was 27.23, The mean surface area of all included human populations was 1.833. The mean age of all patients was (52.06 ± 10.71) years old, and 35 patients developed acute kidney injury after surgery. Multi-factor Logistics regression analysis confirmed the risk factors for postoperative acute kidney injury in overweight patients with acute type A aortic dissection, including gender, CPB transit time and intraoperative infusion of suspended red blood cells. Seven patients in the AKI group died in hospital after surgery and two patients died in the non-AKI group. CONCLUSIONS Among patients with overweight acute Type A aortic dissection, the incidence of AKI is 49.30%. According to multi-factor Logistics regression analysis, gender, CPB transit time and intraoperative suspended red blood cell volume are independent risk factors for postoperative acute kidney injury in patients with overweight acute Type A aortic dissection.

Abstract
Several studies have found that lactate correlates with surgical outcomes in patients with heart disease. However, the prognostic value of postoperative lactate in patients with acute type A aortic dissection (AAAD) remains unclear. This study aimed to investigate the relationship between postoperative lactate and in-hospital mortality in patients with AAAD. Patients who underwent AAAD surgery at Fujian Cardiac Medical Center from February 2020 to January 2022 were enrolled in this retrospective study. Correlations between in-hospital mortality and various parameters, including lactate, were investigated. A total of 357 patients were included in this study, 58 of which died. Multivariate logistic regression analysis revealed that body mass index (BMI) (odds ratio [OR] = 1.099, 95% confidence interval [CI]: 1.017-1.188, P = 0.017), cardiopulmonary bypass (CPB) time (OR = 1.005; 95% CI: 1.000-1.010, P = 0.039), and lactate (OR = 1.291, 95% CI: 1.182-1.409, P < 0.001) were independent risk factors for in-hospital mortality in AAAD patients. Receiver operating characteristic (ROC) curve analysis showed that lactate had a moderate power for in-hospital mortality (area under the curve [AUC] = 0.729, 95% CI: 0.647-0.810, P < 0.001). Furthermore, the combination of lactate, BMI, and CPB time showed better performance (AUC = 0.780; 95% CI: 0.706-0.854, P < 0.001) in predicting in-hospital mortality than in using these variables independently. Among patients undergoing AAAD surgery, postoperative lactate was significantly associated with in-hospital mortality. Lactate can be used as a potential predictor of in-hospital mortality. The combination of lactate, BMI, and CPB time showed better performance in predicting in-hospital mortality than using single one.

Abstract
Background: Serum lactate is commonly measured in the perioperative period in patients who have undergone surgery for an acute type A aortic dissection (ATAAD). However, conflicting data has been reported as to whether lactate elevation is associated with short-term prognosis. The aim of the current study was to determine the association between perioperative arterial lactate levels and postoperative 30-day mortality. Methods: Patients who underwent repair of a ATAAD at our institution were retrospectively screened and those with comprehensive measurements of serum lactate before surgery and at 0, 1, 3, 6, 12, and 24 h after surgery in the intensive care unit (ICU) were selected for the analysis. Patients' demographic features and outcomes were reviewed to determine risk factors associated with 30-day mortality using logistic regression modeling. The association between serum lactate levels at different time points and 30-day mortality were analyzed by receiver-operating characteristic curves. Results: 513 patients were identified and retrospectively analyzed for this study including 66 patients (12.9%) who died within 30 days after surgery. Patients who died within 30 days after surgery had elevated lactate levels measured before surgery and at 0, 1, 3, 6, 12, and 24 h after their ICU stay. Lactate measured at 24 h post ICU admission (odds ratio, 2.131; 95% confidence interval, 1.346-3.374; p = 0.001) was a predictor of 30-day mortality. The area under the curve (AUC) for 30-day mortality with lactate levels at 12 h and 24 h post ICU stay were 0.820 and 0.805, respectively. Conclusion: Early elevation of lactate level is correlated with increased 30-day mortality in patients who received ATAAD surgical repair.

Abstract
BACKGROUND Hyperlactatemia is a common complication in critically ill patients with high morbidity and mortality. Hyperlactatemia patients who require continuous renal replacement therapy (CRRT) constitute a subgroup with increased mortality risk. The clinical significance of serum lactate in these patients was not well understood and clearance of lactate using CRRT shown no survival benefits. The aim of this study is to investigate the incidence and non-lactate risk factors for ICU mortality in hyperlactatemia patients who underwent CRRT. METHOD Hyperlactatemia patients with a serum lactate level >2 μmol/L who underwent CRRT between January, 2014 and May, 2021 were retrospectively investigated. Demographic characteristics and clinical data were collected from the electronic medical record system. The primary endpoint was predictors for ICU mortality which were identified by using multivariate logistic regression analysis. RESULTS A total of 178 eligible patients were finally included with a mean age of 56.6 ± 17.9 years and a median APACHE II score of 18 (IQR (14-22)). The multivariate regression results showed that male gender (OR 0.55 (95%CI 0.27-1.12), p = 0.1), mechanical ventilation (OR 2.60 (95%CI 1.27-5.34), p = 0.008), history of hypertension (OR 2.40 (95%CI 1.12-5.14), p = 0.02), SOFA score (OR 1.16 (95%CI 1.05-1.28), p = 0.002), AST (OR 1.0005 (95%CI 0.99-1.001), p = 0.08), and PT (OR 1.08 (95%CI 0.99-1.17), p = 0.06) were independently associated with ICU mortality. After adjusting for age, illness severity (APACHE II score), and serum lactate level, the statistical significances of SOFA score (OR 1.16 (95%CI 1.04-1.29), p = 0.005), hypertension (OR 2.25 (95%CI 1.02-4.95), p = 0.04), and mechanical ventilation (OR 2.54 (95%CI 1.22-5.25), p = 0.01) were not affected. The overall ICU mortality was 58.4% (104/178). CONCLUSION The hyperlactatemia patients who underwent CRRT were at increased ICU mortality. Gender, AST, PT, SOFA score, history of hypertension, and mechanical ventilation were independent predictors for ICU mortality. Future studies with prospectively design, large sample size, and subgroup analyses are warranted to validate these findings.

Abstract
OBJECTIVE To evaluate the risk factors of postoperative hypoxemia in patients after triple-branched stent graft implantation surgery with acute type A aortic dissection by conducting a nomogram. METHODS We evaluated 97 patients with acute type A aortic dissection (2020-2021), who underwent triple-branched stent graft implantation surgery. The independent risk factors were screened using univariate and multivariate logistic regression. We integrated significant factors as well as potential interference factors to build the nomogram model. The accuracy of the nomogram model was determined by using receiver operating characteristic curves (ROC), decision curve analyses (DCA), and calibration plots. Internal verification was evaluated using bootstrap validation. RESULTS Logistic regression analysis illustrated that the postoperative lactic acid, postoperative creatinine, and intraoperative aortic occlusion time were all independent risk factors for hypoxemia. Age, sex, and body mass index (BMI) were clinically relevant for predicting postoperative hypoxemia. We established a nomogram based on these six risk factors. The ROC (area under the curve [AUC] = 0.765), DCA, and calibration confirmed good discriminatory applicability and accuracy of the nomogram. Bootstrap validation (AUC = 0.76) verified the applicability of the nomogram. CONCLUSIONS The nomogram model could serve as a tool for the prediction of postoperative hypoxemia in patients after modified triple-branched stent graft implantation surgery with acute type A aortic dissection.

Effect of nadir hematocrit during cardiopulmonary bypass on the early outcomes after surgical repair of acute type A aortic dissection. J Card Surg 2022; 37:2338-2347. [PMID: 35545926 DOI: 10.1111/jocs.16590] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Revised: 04/05/2022] [Accepted: 04/17/2022] [Indexed: 11/27/2022]
Abstract
OBJECTIVE Although hemodilution during hypothermic cardiopulmonary bypass (CPB) had been thought to improve microcirculation and reduce blood viscosity, there has been no report investigating the effect of low nadir hematocrit (Hct) values caused by severe hemodilution on the surgical outcomes of patients with acute type A aortic dissection (ATAAD). METHODS We retrospectively reviewed 112 consecutive patients who emergently underwent emergency surgical repair of ATAAD at our institution. The patients were classified into the high Hct (nadir Hct ≥ 21% during CPB; n = 51) and low Hct (nadir Hct < 21% during CPB; n = 61) groups. After propensity score matching of preoperative characteristics, surgical outcomes were compared between the groups. RESULTS Although there was no difference in the surgical procedure, longer CPB time and more blood transfusion during surgery were needed in the low Hct group than in the high Hct group. After surgery, estimated glomerular filtration rate was significantly lower (p = .015), lactaic acid was higher (p = .045), and intubation time was longer (p = .018) in the low Hct group than in the high Hct group, although there was no difference in hospital mortality between the groups. The AUC of the nadir Hct during CPB as a prognostic indicator of prolonged postoperative ventilator support was 0.8, with the highest accuracy at 16.7% (sensitivity 88%, specificity 76.9%). In all cohorts, female sex was an independent risk factor for a lower nadir Hct value of <21% during CPB. CONCLUSION A lower nadir Hct value of <21% during CPB may be associated with postoperative renal dysfunction and prolonged ventilator support in patients with ATAAD.

Shetty V, Shales S, Narayan P. Lactate levels: A reliable tool to predict mortality in acute type A aortic dissections? J Card Surg 2022; 37:1212-1214. [PMID: 35172380 DOI: 10.1111/jocs.16322] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Accepted: 01/27/2022] [Indexed: 11/28/2022]
Abstract
Lactate levels are surrogate markers of malperfusion in patients presenting with type A aortic dissections. Lactate measurement is simple, easy to perform, universally available, and thus can be an important tool for predicting mortality. However, the discriminatory power varies between studies and no cut-off point has been defined that can determine outcomes in the most reliable fashion. The risk prediction based on lactate levels can be improved when combined with other clinical and laboratory prognostic factors. Further studies with a much larger sample size, need to be carried out using serial measurements at well-defined time points to try and identify a cut-off value. The addition of lactate values to existing risk prediction scores or developing a new score based on it should be the subject of future research.
