SinoSCORE对冠状动脉旁路移植术患者生活质量的预测价值

目的 探讨中国冠状动脉旁路移植手术风险评估系统（Sino System for Coronary Operative Risk Evaluation，SinoSCORE）对冠状动脉旁路移植术（CABG）患者生活质量的预测价值。 方法 选取2008年11月至2010年9月在北京大学人民医院行CABG患者共234例，其中男172例，女62例；年龄（63.0±10.1）岁。分别于术前和术后6个月向患者发放SF-36 生活质量调查简表评估患者生活质量。将234例患者根据其SinoSCORE评分分成低危组（≤1分、67例），中危组（2～5分、77例）和高危组（≥6分、90例）3组。收集所有患者的围手术期资料，使用SinoSCORE对每位患者进行评分，分析SinoSCORE评分与生活质量评分的相关性。 结果 各组患者术后生活质量评分均较术前提高，且差异有统计学意义（P＜0.05），3组患者生活质量改善程度差异无统计学意义。相关性分析表明，多个维度的生活质量评分与SinoSCORE评分相关（r值：-0.150～0.255，P＜0.05）。线性回归分析显示，术后躯体健康总评分等多个维度与SinoSCORE评分之间有线性关系（P＜0.05），但相关性较弱（r2＜0.1）。 结论SinoSCORE评分与患者生活质量相关，尤其是在躯体健康方面相关性更强，SinoSCORE有预测CABG患者生活质量的价值，但预测价值有限。

Predictive Value of SinoSCORE on Quality of Life in Patients Undergoing Coronary Artery Bypass Grafting

Objective To verify the predictive value of Sino System for Coronary Operative Risk Evaluation（SinoSCORE） on quality of life in patients undergoing coronary artery bypass graft （CABG） surgery. Method A total of 234 patients in Peking University People’s Hospital undergoing CABG between November 2008 and September 2010 hadcompleted the preoperative and 6-month postoperative Short Form-36 （SF-36）. There were 172 （73.5%） male patients and63 （26.5%） female patients. The average age was 63.0±10.1 years. According to the SinoSCORE， 234 patients were dividedinto three groups：low risk （SinoSCORE score less than 1 point，n=67）， medium risk （SinoSCORE score 2-5 points，n=77） and high risk （SinoSCORE score more than 6 points，n=90） group. Clinical information of the 234 patients was collected， andthe score values of all patients were calculated according to the SinoSCORE model. Statistic methods were performed toevaluate the relationship between quality of life and SinoSCORE. Results The postoperative quality of life have improvedsignificantly， but the improvement of quality of life have no significantly different between groups. There was statisticallysignificant correlation between quality of life and SinoSCORE （P＜0.05， r value at-0.150 to 0.255）.Linear regression analysis showed that SinoSCORE was significantly collected with quality of life in multiple subgroups （P＜0.05， r 2＜0.1） .Conclusion SinoSCORE have statistically correlated with quality of life， and have certain but limited predictive value on quality of life in CABG patients.
