To determine the frequency of stroke and common factors leading to it after coronary artery bypass grafting.
This study was conducted at Cardiothoracic Surgery Department, Rehman Medical Institute, Peshawar. Study design was descriptive cross sectional study and the duration of the study was six months. The total sample size was 183 cases using 8.3% frequency of stroke after coronary artery bypass grafting, 95% confidence interval, 4% margin of error, using WHO sample size calculator.
In this study mean age was 45 years with SD ± 1.26. Seventy five percent patients were male while 46(25%) females. Six patients (3%) patients had stroke while 177(97%) patients did not have any stroke. Among the six patients who were analyzed, all of them had Diabetes Mellitus and 50% patients had recent AMI, while only one patient had prior history of Atrial Fibrillation.
Diabetes Mellitus is an independent risk factor for stroke after CABG surgery. whereas, recent MI is also associated with increased incidence of stroke in post CABG patients.
确定冠状动脉搭桥术后中风的发生率及导致中风的常见因素。
本研究在白沙瓦雷曼医学院心胸外科进行。研究设计为描述性横断面研究，研究时长为六个月。使用世界卫生组织样本量计算器，以冠状动脉搭桥术后8.3%的中风发生率、95%的置信区间、4%的误差幅度计算，总样本量为183例。
本研究中平均年龄为45岁，标准差为±1.26。75%的患者为男性，46名（25%）为女性。6名（3%）患者发生中风，177名（97%）患者未发生任何中风。在分析的6名患者中，他们均患有糖尿病，50%的患者近期发生过急性心肌梗死，而只有1名患者有房颤病史。
糖尿病是冠状动脉搭桥术后中风的独立危险因素。此外，近期心肌梗死也与冠状动脉搭桥术后患者中风发生率增加有关。
