Gender is Independently Associated With Red Blood Cell and Platelet Transfusion in Patients Undergoing Coronary Artery Bypass Grafting: Data From the Netherlands Heart Registration.

OBJECTIVES: The aim of this study was to evaluate the incidence of transfusions, including red blood cells (RBC), platelets, and fresh frozen plasma (FFP) during and after coronary artery bypass grafting (CABG) in the Netherlands. Furthermore, the authors aimed to identify the impact of sex on blood product transfusion. DESIGN: A retrospective multicenter cohort study. Data were collected from January 2013 to December 2021 from the Netherlands Heart Registration (NHR) database. SETTING: The NHR receives its data from 16 heart centers in the Netherlands. PARTICIPANTS: Patients older than 18 years who underwent CABG in the Netherlands. INTERVENTIONS: Coronary artery bypass grafting with extracorporeal circulation or off-pump coronary artery bypass grafting. MEASUREMENTS AND MAIN RESULTS: The incidence of blood transfusion, defined as transfusions intraoperatively and during the length of the hospital admission after CABG. In addition, a differentiation was made according to the type of transfusion (packed RBC, platelets, and FFP). In the overall cohort (N = 42,388), the number of patients who received a transfusion of any type was 27.0% (n = 11,428). Women received more often RBC transfusions compared with men (45.4% v 15.6%, respectively, p < 0.001). There was a significant difference between the 2 sexes regarding platelet transfusion (women 10.0% v men 11.1%, p = 0.005) but not in FFP transfusion. Female sex was independently associated with RBC transfusion, using the multivariate logistic regression analysis. CONCLUSIONS: The incidence of any blood transfusion was 27.0%, and was higher in women than in men. The female sex was independently associated with receiving RBC during and after CABG.

Thoracoscopic-assisted, minimally invasive versus off-pump bypass grafting for single vessel coronary artery disease - A propensity matched analysis.

OBJECTIVE: This study compared perioperative outcomes after off-pump revascularization through a thoracoscopic-assisted (non-robotic) minimally invasive approach (Endo-CAB) or sternotomy approach (OPCAB) for patients with single vessel left anterior descending (LAD) disease. METHODS: In this retrospective, propensity matched cohort study, 266 consecutive patients were included in the Endo-CAB group (n = 136) and OPCAB group (n = 130). After propensity score matching 116 Endo-CAB and 116 OPCAB patients were compared. 'Textbook outcome' was defined as the absence of 30-day mortality, re-exploration for bleeding, postoperative ischemia, cardiac tamponade, cerebrovascular events, wound infection, new-onset arrhythmias, pneumonia, placement of chest drains and prolonged hospital stay (> 7 days). Multivariable regression analysis was performed to identify independent predictors for textbook outcome. RESULTS: Textbook outcome occurred significantly more frequent in the Endo-CAB group compared to the OPCAB group (81.9% vs. 59.5%, p < 0.001). Patients undergoing Endo-CAB surgery had shorter hospital admission (3.0 [3.0-4.0] vs. 5.0 [4.0-6.0] days, p < 0.001), less blood loss (225 [150-355] vs. 450 [350-600] mL, p < 0.001). Other perioperative outcomes were comparable for both groups. Regression analysis demonstrated that Endo-CAB approach was an independent positive predictor for textbook outcome (OR 3.02, 95% CI 1.61-5.66, p < 0.001). CONCLUSIONS: Our study suggests that patients undergoing Endo-CAB surgery have improved perioperative outcome resulting in higher rates of textbook outcome for the treatment of single vessel CAD. This technique could be widely available since routine thoracoscopic instruments are used.
