Abstract

Background: EuroScore (ES) models have been used over the last twenty years for risk assessment before coronary artery bypass graft surgery (CABG) with variation in their ability to assess the overall complications after surgery, the intensive care unit (ICU) stay and heart performance after revascularization in different areas over the world. Objective: To assess the performance of the EuroSCORE in prediction of post-CABG complications at Azadi Heart Center (AHC). Patients and Methods: This correlation study was conducted at AHC, Duhok, Kurdistan Region (Iraq). The study participants were 50 patients (38 males and 12 females) who underwent CABG surgery; informed consent was obtained from all of them for participation in this study. EuroScore II (ES II) model has been assessed before and after CABG, and its correlations with short-term (up to one month) post-operative outcomes were studied. Results: Patients were grouped into low, moderate and high-risk groups each with frequency of 26, 21 and 3, respectively. There was significant correlation between the pre-operative ES II and the post-operative ejection fraction (EF%) in the high-risk group, while there were non-significant correlations with the short-term overall complications and the ICU stay postoperatively. Conclusions: ES II can be used in AHC to predict post-operative EF%, the higher the ES II, the lower post-operative EF%. However, ES II is not valuable to predict other short-term post-operative complications following CABG surgery. Duhok Med J 2020; 14 (1): 53-62
euroscore风险评分系统对伊拉克库尔德地区azadi心脏中心-duhok接受冠状动脉搭桥手术患者的预测有效性
背景:在过去的二十年中,EuroScore (ES)模型被用于冠状动脉搭桥手术(CABG)前的风险评估,其评估手术后总体并发症、重症监护病房(ICU)住院时间和血运重建术后心脏表现的能力在世界不同地区有所不同。目的:评价EuroSCORE对阿扎迪心脏中心(AHC)冠脉搭桥术后并发症的预测作用。患者和方法:本相关性研究在伊拉克库尔德斯坦地区杜霍克AHC进行。研究对象为50例接受CABG手术的患者(38例男性,12例女性);所有参与者都获得了参与本研究的知情同意。在CABG前后评估EuroScore II (ES II)模型,并研究其与术后短期(长达一个月)预后的相关性。结果:将患者分为低、中、高危组,发生率分别为26例、21例、3例。高危组术前ESⅱ与术后射血分数(EF%)有显著相关性,与短期总并发症及术后ICU住院时间无显著相关性。结论:ESⅱ可用于AHC预测术后EF%, ESⅱ越高,术后EF%越低。然而,ES II对于预测CABG术后其他短期并发症没有价值。杜霍克医学杂志2020;14 (1): 53-62
