Impaired fasting glucose is associated with increased perioperative cardiovascular event rates in patients undergoing major non-cardiothoracic surgery

<p>Abstract</p> <p>Background</p> <p>Diabetes mellitus (DM) is a well-established risk factor for perioperative cardiovascular morbidity and mortality in patients undergoing noncardiac surgery. However, the impact of preoperative glucose levels on perioperative cardiovascular outcomes in patients undergoing nonemergent, major noncardiothoracic surgery is unclear.</p> <p>Methods and Results</p> <p>A total of 680 patients undergoing noncardiothoracic surgery were prospectively evaluated. Patients older than 18 years who underwent an elective, nonday case, open surgical procedure were enrolled. Electrocardiography and cardiac biomarkers were obtained 1 day before surgery, and on days 1, 3 and 7 after surgery. Preoperative risk factors and laboratory test results were measured and evaluated for their association with the occurrence of in-hospital perioperative cardiovascular events. Impaired fasting glucose (IFG) defined as fasting plasma glucose values of 100 to 125 mg/dl; DM was defined as fasting plasma glucose ≥ 126 mg/dl and/or plasma glucose ≥ 200 mg/dl or the current use of blood glucose-lowering medication, and glucose values below 100 mg/dl were considered normal. Plasma glucose levels were significantly higher in patients with perioperative cardiovascular events (n = 80, 11.8%) in comparison to those without cardiovascular events (131 ± 42.5 <it>vs </it>106.5 ± 37.5, p < 0.0001). Multivariate analysis revealed that patients with IFG and DM were at 2.1- and 6.4-fold increased risk of perioperative cardiovascular events, respectively. Every 10 mg/dl increase in preoperative plasma glucose levels was related to a 11% increase for adverse perioperative cardiovascular events.</p> <p>Conclusions</p> <p>Not only DM but also IFG is associated with increased perioperative cardiovascular event rates in patients undergoing noncardiothoracic surgery.</p

Impact of perioperative acute ischemic stroke on the outcomes of noncardiac and nonvascular surgery: a single centre prospective study

WOS: 000337748900001PubMed ID: 24869617Background: Although ischemic stroke is a well-known complication of cardiovascular surgery it has not been extensively studied in patients undergoing noncardiac surgery. The aim of this study was to assess the predictors and outcomes of perioperative acute ischemic stroke (PAIS) in patients undergoing noncardiothoracic, nonvascular surgery (NCS). Methods: We prospectively evaluated patients undergoing NCS and enrolled patients older than 18 years who underwent an elective, non-daytime, open surgical procedure. Electrocardiography and cardiac biomarkers were obtained 1 day before surgery, and on postoperative days 1, 3 and 7. Results: Of the 1340 patients undergoing NCS, 31 (2.3%) experienced PAIS. Only age (odds ratio [OR] 2.5, 95% confidence interval [CI] 1.01-3.2, p < 0.001) and preoperative history of stroke (OR 3.6, 95% CI 1.2-4.8, p < 0.001) were independent predictors of PAIS according to multivariate analysis. Patients with PAIS had more cardiovascular (51.6% v. 10.6%, p < 0.001) and noncardiovascular complications (67.7% v. 28.3%, p < 0.001). In-hospital mortality was 19.3% for the PAIS group and 1% for those without PAIS (p < 0.001). Conclusion: Age and preoperative history of stroke were strong risk factors for PAIS in patients undergoing NCS. Patients with PAIS carry an elevated risk of perioperative morbidity and mortality.Contexte : Même si l’AVC ischémique est une complication bien connue de la chirurgie cardiovasculaire, elle n’a pas fait l’objet d’études approfondies chez les patients soumis à une chirurgie non cardiaque. Le but de cette étude était d’évaluer les prédicteurs et les conséquences de l’AVC ischémique aigu périopératoire (IAPO) chez des patients soumis à une chirurgie non cardiothoracique et non vasculaire (NCNV). Méthodes : Nous avons évalué de manière prospective les patients soumis à une chirurgie NCNV et inscrit les patients de plus de 18 ans qui subissaient une intervention chirurgicale ouverte non urgente nécessitant une hospitalisation. L’électrocardiogramme et les biomarqueurs cardiaques étaient obtenus 1 jour avant la chirurgie et aux jours 1, 3 et 7 suivant la chirurgie. Résultats : Parmi les 1340 patients soumis à une chirurgie NCNV, 31 (2,3 %) ont présenté un AVC IAPO. Seuls l’âge (rapport des cotes [RC] 2,5, intervalle de confiance [IC] de 95 % 1,01–3,2, p < 0,001) et des antécédents préopératoires d’AVC (RC 3,6, IC de 95 % 1,2–4,8, p < 0,001) ont été des prédicteurs indépendants de l’AVC IAPO selon l’analyse multivariée. Les patients victimes d’un AVC IAPO avaient davantage de complications cardiovasculaires (51,6 % c. 10,6 %, p < 0,001) et non cardiovasculaires (67,7 % c. 28,3 %, p < 0,001). La mortalité perhospitalière a été de 19,3 % dans le groupe victime d’AVC IAPO et de 1 % chez les patients indemnes d’AVC IAPO (p < 0,001). Conclusion : L’âge et les antécédents préopératoires d’AVC sont des facteurs de risque importants à l’égard de l’AVC IAPO chez les patients soumis à une chirurgie NCNV. Les patients victimes d’un AVC IAPO sont exposés à un risque élevé de morbidité et de mortalité périopératoires
