RESUMEN
BACKGROUND: Stress hyperglycemia and glycemic variability (GV) can reflect dramatic increases and acute fluctuations in blood glucose, which are associated with adverse cardiovascular events. This study aimed to explore whether the combined assessment of the stress hyperglycemia ratio (SHR) and GV provides additional information for prognostic prediction in patients with coronary artery disease (CAD) hospitalized in the intensive care unit (ICU). METHODS: Patients diagnosed with CAD from the Medical Information Mart for Intensive Care-IV database (version 2.2) between 2008 and 2019 were retrospectively included in the analysis. The primary endpoint was 1-year mortality, and the secondary endpoint was in-hospital mortality. Levels of SHR and GV were stratified into tertiles, with the highest tertile classified as high and the lower two tertiles classified as low. The associations of SHR, GV, and their combination with mortality were determined by logistic and Cox regression analyses. RESULTS: A total of 2789 patients were included, with a mean age of 69.6 years, and 30.1% were female. Overall, 138 (4.9%) patients died in the hospital, and 404 (14.5%) patients died at 1 year. The combination of SHR and GV was superior to SHR (in-hospital mortality: 0.710 vs. 0.689, p = 0.012; 1-year mortality: 0.644 vs. 0.615, p = 0.007) and GV (in-hospital mortality: 0.710 vs. 0.632, p = 0.004; 1-year mortality: 0.644 vs. 0.603, p < 0.001) alone for predicting mortality in the receiver operating characteristic analysis. In addition, nondiabetic patients with high SHR levels and high GV were associated with the greatest risk of both in-hospital mortality (odds ratio [OR] = 10.831, 95% confidence interval [CI] 4.494-26.105) and 1-year mortality (hazard ratio [HR] = 5.830, 95% CI 3.175-10.702). However, in the diabetic population, the highest risk of in-hospital mortality (OR = 4.221, 95% CI 1.542-11.558) and 1-year mortality (HR = 2.013, 95% CI 1.224-3.311) was observed in patients with high SHR levels but low GV. CONCLUSIONS: The simultaneous evaluation of SHR and GV provides more information for risk stratification and prognostic prediction than SHR and GV alone, contributing to developing individualized strategies for glucose management in patients with CAD admitted to the ICU.

BACKGROUND: The triglyceride-glucose (TyG) index and estimated glucose disposal rate (eGDR), which are calculated using different parameters, are widely used as markers of insulin resistance and are associated with cardiovascular diseases and prognosis. However, whether they have an additive effect on the risk of mortality remains unclear. This study aimed to explore whether the combined assessment of the TyG index and eGDR improved the prediction of long-term mortality in individuals with and without diabetes. METHODS: In this cross-sectional and cohort study, data were derived from the National Health and Nutrition Examination Survey (NHANES) 2001-2018, and death record information was obtained from the National Death Index. The associations of the TyG index and eGDR with all-cause and cardiovascular mortality were determined by multivariate Cox regression analysis and restricted cubic splines. RESULTS: Among the 17,787 individuals included in the analysis, there were 1946 (10.9%) all-cause deaths and 649 (3.6%) cardiovascular deaths during a median follow-up of 8.92 years. In individuals with diabetes, the restricted cubic spline curves for the associations of the TyG index and eGDR with mortality followed a J-shape and an L-shape, respectively. The risk of mortality significantly increased after the TyG index was > 9.04 (all-cause mortality) or > 9.30 (cardiovascular mortality), and after eGDR was < 4 mg/kg/min (both all-cause and cardiovascular mortality). In individuals without diabetes, the association between eGDR and mortality followed a negative linear relationship. However, there was no association between the TyG index and mortality. Compared with individuals in the low TyG and high eGDR group, those in the high TyG and low eGDR group (TyG > 9.04 and eGDR < 4) showed the highest risk for all-cause mortality (hazard ratio [HR] = 1.592, 95% confidence interval [CI] 1.284-1.975) and cardiovascular mortality (HR = 1.683, 95% CI 1.179-2.400) in the overall population. Similar results were observed in individuals with and without diabetes. CONCLUSIONS: There was a potential additive effect of the TyG index and eGDR on the risk of long-term mortality in individuals with and without diabetes, which provided additional information for prognostic prediction and contributed to improving risk stratification.

BACKGROUND: Pre-procedure liver dysfunction was associated with acute kidney injury after percutaneous coronary intervention (PCI). The aim of this study is to assess and compare the predictive value of different liver function scoring systems for contrast-associated acute kidney injury (CA-AKI) in patients undergoing elective PCI.MethodsâandâResults:A total of 5,569 patients were retrospectively enrolled. The model for end-stage liver disease (MELD) including albumin (MELD-Albumin) score (AUC=0.661) had the strongest predictive value in comparison to the MELD score (AUC=0.627), the MELD excluding the international normalized ratio (MELD-XI) score (AUC=0.560), and the MELD including sodium (MELD-Na) score (AUC=0.652). In the fully adjusted logistic regression model, the MELD-Albumin score and the MELD-Na score were independently associated with CA-AKI regardless of whether they were treated as continuous or categorical variables; however, this was not the case for the MELD score and the MELD-XI score. Furthermore, the addition of the MELD-Albumin score significantly improved the reclassification beyond the fully adjusted logistic regression model. The study further explored the association between different versions of the MELD score and CA-AKI using restricted cubic splines and found a linear relationship between the MELD-Albumin score and the risk of CA-AKI. CONCLUSIONS: The MELD-Albumin score had the highest predictive value for CA-AKI in patients undergoing elective PCI. The addition of the MELD-Albumin score to the existing risk prediction model significantly improved the reclassification for CA-AKI.

Liver fibrosis scores have been demonstrated to be associated with poor prognosis after percutaneous coronary intervention (PCI). However, no studies have compared the prognostic value of these scores in acute myocardial infarction (AMI) patients with and without diabetes. We retrospectively enrolled 1576 AMI patients who underwent PCI. There were 177 all-cause deaths and 111 cardiac deaths during follow-up (median 3.8 years). The non-alcoholic fatty liver disease fibrosis score (NFS) showed a better prognostic value than the fibrosis-8 (FIB-8) score (Harrell's C-index: 0.703 vs 0.671, P = .014) and the fibrosis-4 (FIB-4) score (Harrell's C-index: 0.703 vs 0.648, P < .001) in the overall population. In the time-dependent receiver operating characteristic analysis, the NFS also had the highest area under the curve across all time points. Consistent results were observed in diabetic and non-diabetic populations. Adding the NFS to traditional cardiovascular risk factors significantly improved the prediction both for all-cause mortality (Harrell's C-index: 0.806 vs 0.771, P < .001) and cardiac death (Harrell's C-index: 0.800 vs 0.771, P = .014). The NFS showed a better prognostic value than the FIB-8 score and the FIB-4 score in patients with AMI undergoing PCI, which might be preferable for estimating the risk of mortality regardless of the presence or absence of diabetes.

AIMS: Variability of metabolic parameters, such as glycemic variability (GV) and systolic blood pressure variability (SBPV), are associated with adverse cardiovascular outcomes. However, whether these parameters have additive effects on mortality in patients with coronary artery disease (CAD) hospitalized in the intensive care unit (ICU) remains unclear. METHODS: We retrospectively enrolled patients with CAD from the Medical Information Mart for Intensive Care-IV database. The highest tertile of variability was defined as high variability. A variability scoring system was established, which assigned 0 points to tertile 1, 1 point to tertile 2, and 2 points to tertile 3 for GV and SBPV. RESULTS: Among 4237 patients with CAD, 400 patients died in hospital, and 967 patients died during 1-year follow-up. High GV and high SBPV were associated with an increased risk of mortality. The effects of GV and SBPV on in-hospital mortality were partially mediated by ventricular arrhythmias (18.0 % and 6.6 %, respectively). The risk of mortality gradually increased with the number of high-variability parameters and increasing variability scores. CONCLUSIONS: GV and SBPV have additive effects on the risk of mortality in patients with CAD hospitalized in the ICU. Ventricular arrhythmias partially mediate the effects of GV and SBPV on in-hospital mortality.

AIMS: The stress hyperglycemia ratio (SHR) is significantly associated with short-term adverse cardiovascular events. However, the association between SHR and mortality after the acute phase of acute coronary syndrome (ACS) remains controversial. METHODS: This study used data from the Medical Information Mart for Intensive Care-IV database. Patients with ACS hospitalized in the intensive care unit (ICU) were retrospectively enrolled. RESULTS: A total of 2668 ACS patients were enrolled. The incidence of in-hospital and 1-year mortality was 4.7 % and 13.2 %, respectively. The maximum SHR had a higher prognostic value for predicting both in-hospital and 1-year mortality than the first SHR. Adding the maximum SHR to the SOFA score could significantly improve the prognostic prediction. In the landmark analysis at 30 days, the maximum SHR was a risk factor for mortality within 30 days regardless of whether patients had diabetes. However, it was no longer associated with mortality after 30 days in patients with diabetes after adjustment (HR = 1.237 per 1-point increment, 95 % CI 0.854-1.790). CONCLUSIONS: The maximum SHR was significantly associated with mortality in patients with ACS hospitalized in the ICU. However, caution is warranted if it is used for predicting mortality after 30 days in patients with diabetes.

BACKGROUND: The Age-D-dimer-Albumin (ADA), the CREDO-Kyoto, and the PARIS scores have been established to predict thrombotic events. However, the prognostic performance of these scores compared to the GRACE score in patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI) has not been reported. METHODS: Consecutive AMI patients treated with PCI were retrospectively enrolled at a teaching hospital in China from January 2016 to December 2019. The primary endpoint was all-cause mortality and the secondary endpoint was cardiac death. Harrell's C-index and net reclassification improvement (NRI) were used to compare the prognostic value of these scores with the GRACE score for mortality. RESULTS: Of the 1,578 patients enrolled, the mean age was 62.5 years, and 23.5% were female. During a median follow-up of 3.8 years, 146 all-cause deaths and 80 cardiac deaths occurred. The ADA score showed a better prognostic performance than the GRACE (Harrell's C-index: 0.800 vs. 0.749; p = 0.003), the CREDO-Kyoto (Harrell's C-index: 0.800 vs. 0.765; NRI = 0.348, p < 0.001), and the PARIS scores (Harrell's C-index: 0.800 vs. 0.694; NRI = 0.556, p < 0.001). In the multivariable Cox regression analysis, the ADA score was independently associated with all-cause mortality (hazard ratio [HR] = 1.641 per 10-point increment, 95% confidence interval [CI]: 1.397-1.929) and cardiac death (HR = 1.636 per 10-point increment, 95% CI: 1.325-2.020). The risk of all-cause mortality and cardiac death increased with the rising of the ADA score. CONCLUSION: The ADA score showed a better prognostic performance than the GRACE, the CREDO-Kyoto, and the PARIS scores in patients with AMI undergoing PCI, which was a potential predictive tool for mortality.

The model for end-stage liver disease (MELD) score, which can reflect liver and renal function, is associated with poor prognosis. However, the prognostic performance of the modified MELD score in patients undergoing elective percutaneous coronary intervention (PCI) has not been fully evaluated and compared. This study retrospectively enrolled 5324 patients. During a median follow-up of 2.85 years, 412 patients died. Time-dependent receiver operating characteristic curves at 3 years indicated that the MELD including albumin (MELD-Albumin) score had the highest prognostic performance (AUC = .721) than the MELD score (AUC = .630), the MELD excluding the international normalized ratio (MELD-XI) score (AUC = .606), and the MELD including sodium (MELD-Na) score (AUC = .656) (all P < .001). The MELD-Albumin score, the MELD score, and the MELD-Na score were independent predictors of long-term mortality; however, the MELD-XI score was not when treated as a categorical variable (P = .254). Adding the MELD-Albumin score to the model of clinical risk factors could improve the prognostic performance. For the subgroup analysis, the association between the MELD-Albumin score and long-term mortality was more pronounced in patients ≤75 years (interaction P value = .005). The MELD-Albumin score showed the strongest prognostic performance than the other versions of the MELD score in patients undergoing elective PCI.

Previous studies have demonstrated that non-invasive liver fibrosis scores (LFSs) are associated with kidney function deterioration. This study aimed to assess the predictive performance of LFSs in contrast-associated acute kidney injury (CA-AKI) in coronary artery disease (CAD) patients undergoing elective percutaneous coronary intervention (PCI). This retrospective study involved 5627 patients. The frequency of CA-AKI was 6.3% (n = 353). In a multivariate logistic analysis after adjustment, non-invasive LFSs, including fibrosis-5 score (FIB-5), fibrosis-4 score (FIB-4), aspartate aminotransferase to alanine aminotransferase ratio (AAR), and aspartate aminotransferase to platelet ratio index were independent risk factors for CA-AKI (all P < .05), whereas the Forns score was not (P > .05). The highest predictive performance was observed for FIB-5 (area under the curve [AUC] = .644) compared to other LFSs. A restricted cubic spline analysis confirmed approximately linear relationships between LFSs and risks of CA-AKI. Furthermore, adding FIB-5 (AUC = .747; net reclassification improvement [NRI] = .441, P < .001; integrated discrimination improvement [IDI] = .008, P < .001) or AAR (AUC = .747; NRI = .419, P < .001; IDI = .006, P = .010) to an established clinical risk model could significantly improve the prediction of CA-AKI. The LFSs were significantly associated with CA-AKI, possibly serving as predictive tools for early identification of CAD patients undergoing elective PCI that are at high risk of CA-AKI.

BACKGROUND: Pre-procedure liver insufficiency has been demonstrated as a poor prognostic factor after percutaneous coronary intervention (PCI). Recent research discovered that the aspartate aminotransferase-to-alanine aminotransferase ratio (De-Ritis ratio) reflects the severity of liver insufficiency and was associated with adverse outcomes. We aim to evaluate the predictive value of the De-Ritis ratio for contrast-associated acute kidney injury (CA-AKI) and long-term mortality in patients undergoing elective PCI. METHODS: We retrospectively enrolled 5780 consenting patients undergoing elective PCI between January 2012 and December 2018. CA-AKI was defined as an increase in serum creatinine ≥0.3 mg/dl or ≥50% within 48 h after the administration of contrast media. RESULTS: The incidence of CA-AKI was 6.3% (n = 363). The De-Ritis ratio >1.30 was identified as the best cut-off value for CA-AKI prediction. The De-Ritis ratio showed an area under the curve (AUC) of 0.636 [95% confidence interval (CI): 0.605-0.667] in predicting CA-AKI, which was significantly greater than alanine aminotransferase (p<0.001) and aspartate aminotransferase (p = 0.012) alone. Furthermore, compared to currently recognized liver function assessment tools, the predictive value of the De-Ritis ratio on CA-AKI was similar to the MELD score (AUC: 0.636 vs 0.626, p = 0.631) and higher than the MELD-XI score (AUC: 0.636 vs 0.561, p<0.001). Multivariate logistic analysis showed that the De-Ritis ratio >1.30 was independently associated with CA-AKI (odds ratio=1.551, 95% CI: 1.185-2.030, p = 0.001). The addition of the De-Ritis ratio to the fully adjusted logistic regression model has significant incremental effects on the risk prediction for CA-AKI with a continuous net reclassification improvement of 0.395 (p<0.001) and an integrated discrimination improvement of 0.005 (p = 0.018). Additionally, the De-Ritis ratio >1.30 was significantly associated with long-term mortality (hazard ratio=1.285, 95% CI: 1.007-1.641, p = 0.044). CONCLUSIONS: The De-Ritis ratio was an independent risk factor for CA-AKI and long-term mortality in patients undergoing elective PCI.

BACKGROUND: Neutrophil and albumin are well-known biomarkers of inflammation, which are highly related to contrast-associated acute kidney injury (CA-AKI). We aim to explore the predictive value of neutrophil percentage-to-albumin ratio (NPAR) for CA-AKI and long-term mortality in patients without chronic kidney disease (CKD) undergoing elective percutaneous coronary intervention (PCI). METHODS: We retrospectively observed 5083 consenting patients from January 2012 to December 2018. CA-AKI was defined as an increase in serum creatinine ≥50% or 0.3 mg/dL within 48 h after contrast medium exposure. RESULTS: The incidence of CA-AKI was 5.6% (n=286). The optimal cut-off value of NPAR for predicting CA-AKI was 15.7 with 66.8% sensitivity and 61.9% specificity [C statistic=0.679; 95% confidence interval (CI), 0.666-0.691]. NPAR displayed higher area under the curve values in comparison to neutrophil percentage (p < 0.001) and neutrophil-to-albumin ratio (NAR) (p < 0.001), but not albumin (p = 0.063). However, NPAR significantly improved the prediction of CA-AKI assessed by the continuous net reclassification improvement (NRI) and integrated discrimination improvement (IDI) compared to neutrophil percentage (NRI=0.353, 95% CI: 0.234-0.472, p < 0.001; IDI=0.017, 95% CI: 0.010-0.024, p < 0.001) and albumin (NRI=0.141, 95% CI: 0.022-0.260, p = 0.020; IDI=0.009, 95% CI: 0.003-0.015, p = 0.003) alone. After adjusting for potential confounding factors, multivariate analysis showed that NPAR >15.7 was a strong independent predictor of CA-AKI (odds ratio =1.90, 95% CI: 1.38-2.63, p < 0.001). Additionally, NPAR >15.7 was significantly associated with long-term mortality during a median of 2.9 years of follow-up (hazard ratio =1.68, 95% CI: 1.32-2.13; p < 0.001). CONCLUSIONS: NPAR was an independent predictor of CA-AKI and long-term mortality in patients without CKD undergoing elective PCI.
