Bypass Surgery Outcomes Still Good Despite Ageing Population, Australia

Article Date: 17 Feb 2008 - 13:00 PST

Despite an ageing population, outcomes for coronary artery bypass graft (CABG) surgery patients in Victoria remained steady between 2001 and 2006, and 30-day mortality rates are still low, according to a study published in the latest Medical Journal of Australia.

Dr Diem Dinh - Research Fellow at the Department of Epidemiology and Preventive Medicine at Monash University - and co-authors studied the preoperative risk factors and postoperative outcomes of patients undergoing CABG surgery in Victoria over the five-year period 2001-2006.

Rates of 30-day mortality and postoperative risk of disease after CABG surgery have remained steady despite an increase in the age of patients, Dr Dinh says.

\"The mean age of patients undergoing isolated CABG surgery increased from 65.4 years in 2001-02 to 66 years in 2005-06.

\"There was also an increase in the proportion of patients with hypertension, respiratory disease, and left main coronary artery disease.

\"The number of patients undergoing repeat CABG surgery decreased.\"

The low mortality rate is the same as that reported in the United Kingdom and is lower than the United States.

Dr Dinh says further research is needed into the longer-term outcomes of CABG surgery patients, as well as a comparison between outcomes in other Australian states and territories.

\"We are in the process of developing a web-based system that will streamline data collection and provide real-time benchmarking measures.\"

　　根据最近出版的澳大利亚医学杂志上的一项调查，尽管人口老龄化，在xxx冠状动脉旁路移植术患者的预后在２００１年到２００６年期间一直保持稳定，并且３０天的死亡率仍然很低。
　　迪姆.廷博士――莫纳什大学流行病学与预防医学系的研究人员，和他的合著者一起研究了在２００１年至２００６年之间在xxx经过冠脉旁路移植术的患者的术前危险因素和术后预后超过了五年。
　　廷博士说：“尽管患者的年龄增长，但冠状动脉旁路移植术后的３０天死亡率和疾病的术后危险已经趋向于稳定。”实施隔离的冠状动脉旁路移植术患者的平均年龄从２００１－２００２年的６５.４岁增长到２００５－２００６年的６６岁。伴有高血压，呼吸系统疾病，和左冠状动脉主干病变的患者的比例也有一定的增长。实施二次冠状动脉旁路移植术的患者数目下降了。低死亡率和英国报告的一样，而且比美国要低。
　　廷博士声明需要进一步调查冠状动脉旁路移植术患者的长期预后，也同澳大利亚的其它洲和地区之间进行一个对照。我们正在进行一种基于web系统的开发，这种系统将提高数据收集的效率，并且能够提供实时的规范措施。
