Objective: Developing and assessing a risk prediction model of postoperative atrial fibrillation (POAF) after coronary artery bypass grafting (CABG), and aims to provide a reference for the prediction and prevention.
Design: A retrospective case-control study.
Setting: Three major urban teaching and university hospitals and tertiary referral centers.
Objectives: Postoperative neurological deficits remain a challenge in cardiac surgery employing deep hypothermic circulatory arrest (DHCA). This study aimed to investigate the effect of WIN55, 212-2, a cannabinoid agonist, on brain injury in a rat model of DHCA.
Methods: Twenty-four male Sprague Dawley rats were randomly divided into three groups: a control group (which underwent cardiopulmonary bypass (CPB) only), a DHCA group (CPB with DHCA), and a WIN group (WIN55, 212-2 pretreatment before CPB with DHCA).
Article Synopsis
- The study aimed to analyze the in-hospital outcomes of young (≤ 65 years) and old (> 65 years) patients after coronary artery bypass grafting (CABG), focusing on how age influences adverse events.
- Methods included comparing patient data using statistical tests and multifactor binary logistic regression to control for confounding factors.
- Results showed that older patients had higher risks of postoperative in-hospital mortality, symptomatic cerebral infarction, and atrial fibrillation, especially in on-pump CABG, while off-pump CABG also indicated higher risk of atrial fibrillation in older patients.
Objective: This study aims to analyze the association between preoperative LDL/HDL ratio and new-onset atrial fibrillation (AF) after on-pump coronary artery bypass grafting (on-pump CABG), evaluate the clinic value of preoperative LDL/HDL ratio to identify postoperative rhythm.
Methods: A retrospective study of consecutive patients (n = 2052) who underwent on-pump CABG at TEDA International Cardiovascular Hospital (Tianjin, China), from June 1, 2020, to December 30, 2021, was conducted. The association between preoperative LDL/HDL and new-onset POAF was analyzed by Lowess curve and univariate logistic regression.
