The prognostic value of postoperative blood glucose in non-diabetic patients with rheumatic heart disease.

BACKGROUND: Blood glucose (BG) is a risk factor of adverse prognosis in non-diabetic patients in several conditions. However, a limited number of studies were performed to explore the relationship between postoperative BG and adverse outcomes in non-diabetic patients with rheumatic heart disease (RHD). METHODS: We identified 1395 non-diabetic patients who diagnosed with having RHD, and underwent at least one valve replacement and preoperative coronary angiography. BG was measured at admission to the intensive care unit (ICU) after surgery. The association of postoperative BG level with in-hospital and one-year mortality was accordingly analyzed. RESULTS: Included patients were stratified into four groups according to postoperative BG level's (mmol/L) quartiles: Q1 (< 9.3 mmol/L, n = 348), Q2 (9.3-10.9 mmol/L, n = 354), Q3 (10.9-13.2 mmol/L, n = 341), and Q4 (≥ 13.2 mmol/L, n = 352). The in-hospital death (1.1% vs. 2.3% vs. 1.8% vs. 8.2%, P < 0.001) and MACEs (2.0% vs. 3.1% vs. 2.6% vs. 9.7%, P < 0.001) were significantly higher in the upper quartiles. Postoperative BG > 13.0 mmol/L was the best threshold for predicting in-hospital death (area under the curve (AUC) = 0.707, 95% confidence interval (CI): 0.634-0.780, P < 0.001). Multivariate logistic regression analysis indicated that postoperative BG > 13.0 mmol/L was an independent predictor of in-hospital mortality (adjusted odds ratio (OR) = 3.418, 95% CI: 1.713-6.821, P < 0.001). In addition, Kaplan-Meier curve analysis showed that the risk of one-year death was increased for a postoperative BG > 13.2 (log-rank = 32.762, P < 0.001). CONCLUSION: Postoperative BG, as a routine test, could be served as a risk measure for non-diabetic patients with RHD.

Utility of age, creatinine, and ejection fraction score in patients with type B aortic dissection undergoing thoracic endovascular aortic repair.

BACKGROUND: Older age, renal and cardiac dysfunction are predictors of poor outcome in aortic dissection. The aim of this study was to evaluate the association of the age, creatinine and ejection fraction (ACEF) score with adverse events in patients with type B aortic dissection (TBAD) undergoing thoracic endovascular aortic repair (TEVAR). METHODS: The study enrolled 605 patients from January 2010 to July 2015, who were classified into three groups according to the tertiles of ACEF score: Tertile 1 (≤0.77, n = 204), Tertile 2 (0.77-0.96, n = 205) and Tertile 3 (>0.96, n = 196). The association between ACEF, AGEF (age, glomerular filtration rate and ejection fraction) and the updated version of the ACEF (ACEF II) score with adverse events was analyzed. RESULTS: After a median 3.4 years follow-up, 63 (10.4%) patients died. Multivariable analysis revealed that ACEF score was independently associated with long-term mortality (adjusted hazard ratio = 3.54; 95% confidence interval, 2.09-6.01; p < 0.001). ACEF, AGEF and ACEF II score had similar predictive ability for both in-hospital and long-term death. The in-hospital mortality (1.5% vs. 1.0% vs. 6.6%, p = 0.001) were significantly higher in Tertile 3. In addition, cumulative long-term mortality in Tertile 3 was significantly higher than that in Tertile 1 and 2 (Log-Rank = 23.74; p < 0.001). CONCLUSION: ACEF score could be served as an useful and relatively simple tool for pre-TEVAR risk stratification in TBAD patients.
