Patients with increased glycated hemoglobin (HbA1c) seem to be at increased risk of sternal wound infection (SWI) after coronary artery bypass grafting (CABG). However, it is unclear whether ...increased baseline HbA1c levels may affect other postoperative outcomes.
Data on preoperative levels of HbA1c were collected from 2606 patients undergoing elective isolated CABG from 2015 to 2016 and included in the prospective, multicenter E-CABG registry.
The prevalence of HbA1c ≥ 53 mmol/mol (7.0%) among non-diabetics was 5.3%, among non-insulin dependent diabetics was 53.5% and among insulin dependent diabetics was 67.1% (p < 0.001). The prevalence of HbA1c > 75 mmol/mol (9.0%) among non-diabetics was 0.5%, among non-insulin dependent diabetics was 5.8% and among insulin dependent diabetics was 10.6% (p < 0.001). Baseline levels of HbA1c ≥ 53 mmol/mol (7.0%) was a significant predictor of any SWI (10.7% vs. 3.3%, adjusted p-value: <0.001), deep SWI/mediastinitis (3.8% vs. 1.3%, adjusted p-value: 0.001) and acute kidney injury (27.4% vs. 19.8%, adjusted p-value: 0.042). These findings were confirmed in multilevel mixed effect logistic regression adjusted for participating centers. Among patients with diabetes, HbA1c ≥ 53 mmol/mol (7.0%) was predictive of SWI (11.1% vs. 4.8%, p = 0.001).
HbA1c is increased in a significant proportion of patients undergoing elective CABG and these patients are at higher risk of SWI. Less clear is the impact of increased HbA1c on other postoperative outcomes. These results do not support screening of HbA1c in patients without history of diabetes. Preoperative screening of HbA1c is valuable only to identify diabetics at risk of SWI.
•HbA1c is increased in a significant number of patients undergoing coronary surgery.•Preoperative screening of HbA1c is not justified in non-diabetic patients undergoing coronary surgery.•Preoperative screening of HbA1c is identifies diabetics at high risk of sternal wound infection after coronary surgery.•Less clear is the impact of increased HbA1c on other postoperative outcomes.
Background Multiple percutaneous coronary interventions ( PCIs ) are considered determinant of poor outcome in patients undergoing coronary artery bypass grafting ( CABG ), but scarce data exist to ...substantiate this. Methods and Results Patients who underwent CABG without history of prior PCI or with PCI performed >30 days before surgery were selected for the present analysis from the prospective, multicenter E-CABG (European Multicenter Study on Coronary Artery Bypass Grafting) registry. Out of 6563 patients with data on preoperative SYNTAX (Synergy between PCI With Taxus and Cardiac Surgery) score, 1181 patients (18.0%) had undergone PCI >30 days before CABG . Of these, 11.6% underwent a single PCI , 4.4% 2 PCI s, and 2.1% ≥3 PCI s. PCI of a single main coronary vessel was performed in 11.3%, of 2 main vessels in 4.9%, and of 3 main vessels in 1.6% of patients. Multivariable analysis showed that differences in early mortality and other outcomes were not significantly different in the study cohorts. The adjusted hospital/30-day mortality rate was 1.8% in patients without history of prior PCI , 1.9% in those with a history of 1 PCI , 1.4% after 2 PCI s, and 2.5% after ≥3 PCI s (adjusted P=0.8). The adjusted hospital/30-day mortality rate was 2.0% in those who had undergone PCI of 1 main coronary vessel, 1.3% after PCI of 2 main vessels, and 3.1% after PCI of 3 main coronary vessels (adjusted P=0.6). Conclusions Multiple prior PCI s are not associated with increased risk of early adverse events in patients undergoing isolated CABG . The present results are conditional to survival after PCI and should not be viewed as a support for a policy of multiple PCI as opposed to earlier CABG .

IntroductionTraditional and transcatheter surgical treatments of severe aortic valve stenosis (SAVS) are increasing in parallel with the improved life expectancy. Recent randomised controlled trials ...(RCTs) reported comparable or non-inferior mortality with transcatheter treatments compared with traditional surgery. However, RCTs have the limitation of being a mirror of the predefined inclusion/exclusion criteria, without reflecting the ‘real clinical world’. Technological improvements have recently allowed the development of minimally invasive surgical accesses and the use of sutureless valves, but their impact on the clinical scenario is difficult to assess because of the monocentric design of published studies and limited sample size. A prospective multicentre registry including all patients referred for a surgical treatment of SAVS (traditional, through full sternotomy; minimally invasive; or transcatheter; with both ‘sutured’ and ‘sutureless’ valves) will provide a ‘real-world’ picture of available results of current surgical options and will help to clarify the ‘grey zones’ of current guidelines.Methods and analysisEuropean Aortic Valve Registry is a prospective observational open registry designed to collect all data from patients admitted for SAVS, with or without coronary artery disease, in 16 cardiac surgery centres located in six countries (France, Germany, Italy, Spain, Switzerland and UK). Patients will be enrolled over a 2-year period and followed up for a minimum of 5 years to a maximum of 10 years after enrolment. Outcome definitions are concordant with Valve Academic Research Consortium-2 criteria and established guidelines. Primary outcome is 5-year all-cause mortality. Secondary outcomes aim at establishing ‘early’ 30-day all-cause and cardiovascular mortality, as well as major morbidity, and ‘late’ cardiovascular mortality, major morbidity, structural and non-structural valve complications, quality of life and echocardiographic results.Ethics and disseminationThe study protocol is approved by local ethics committees. Any formal presentation or publication of data will be considered as a joint publication by the participating physician(s) and will follow the recommendations of the International Committee of Medical Journal Editors for authorship.Trial registration number NCT03143361; Pre-results.

Although improved long-term outcomes obtained with the use of arterial grafts for coronary revascularization in comparison with the traditional association of a single arterial and saphenous vein ...grafts have been demonstrated in the overall population, the efficacy of this newer technique in the elderly is difficult to prove because their shorter life expectancy due to advanced heart disease, associated with severe comorbidities. Moreover, more widespread use of this technique is limited by the concerns on the potential morbidity, particularly the longer time required to perform the operation and the possibility of deep sternal wound infection in case of bilateral internal thoracic artery harvesting due to the decreased blood supply to the sternum and surrounding tissues.The review of the recent literature indicates that the use of bilateral internal thoracic arteries in very elderly patients should not be considered routinely. It seems reasonable to avoid it in octogenarians in the presence of well-known predictors of sternal complications such as diabetes, morbid obesity, and severe chronic lung disease.There is also still controversy about the superiority of the radial artery over the saphenous vein graft as a second or third conduit for surgical myocardial revascularization, although the majority of recent studies seem to support more liberal use of the radial artery as second arterial conduit in the elderly. Although a clinical benefit of arterial graft revascularization cannot be formally excluded for elderly patients, the increased complexity of this technique suggests that careful clinical judgment is necessary to select grafts for individual patients.
Purpose: The introduction of transcatheter aortic valves has focused attention on the results of conventional aortic valve surgery in high-risk patients. The aim of the study was to evaluate 5-years ...outcomes in this category of patients in the current surgical era.Methods: This is an observational retrospective study of 581 high-risk patients undergoing aortic valve replacement from 2008 to 2013, with a mean logistic EuroSCORE of 26.6% ± 14.6%. Data were prospectively collected in a database of Emilia-Romagna region (Italy).Results: Overall 30-day mortality was 9.3%. Stroke rate was 1.5%. At 1-, 3-, and 5-years overall mortality was 18.2%, 30.4%, and 42.2%, cardiac death rate was 3.9%, 9.2%, and 12.9%, stroke rate 2.5%, 7.7%, and 10.2%, re-operation occurrence 0.2%, 0.9% and 1.3%, and new pacemaker implantation was 2.3%, 5.1% and 7.8%. At multivariate analysis, urgency, hemodynamic instability, LVEF ≤30%, NYHA III-IV, severe chronic obstructive pulmonary disease (COPD), extra-cardiac arteriopathy, cerebrovascular disease, and creatinine >2.0 mg/dL remained independent predictors of 5-year mortality.Conclusion: The results of the current study add weight to the evidence that traditional aortic valve replacement can be performed in high-risk patients with satisfactory 5-year mortality and morbidity. Our study may help to improve decision-making in this category of high-risk patients with aortic valve disease.
