摘要
目的探讨肥胖是否影响心血管外科手术的预后。方法采用回顾性研究法，对在我院接受心脏外科手术的1052例病人进行研究。根据BMI分为A（正常体重）、B（超重）和C（肥胖）三组，应用x^2检验、logistic回归、多元线性回归等方法，对各组多项指标进行比较和分析。结果C组住院时间、ICU停留时间以及术后呼吸机使用时间均明显长于A组；三组问病死率差异无统计学意义，但肾功能不全、需要透析和房颤的发生率C组明显高于A组。结论肥胖不影响心血管外科术后总病死率和多数并发症，但可通过多种途径间接增加费用支出，且具有潜在的增加手术风险可能。
Objective To explore whether obesity play a role in the prognosis of cardiac surgery in Chinese. Methods A total of 1052 patients who received cardiac surgery between January 1st 1997 and December 31 st 2005 were included in cardiovascular center of Beijing Tongren Hospital. They were divided into three groups by BMI, the patients with BMI 〈 24 were considered as normal or control （ group A） ,24 - 28 as overweight（ group B）, and ≥28 as obese group（ group C）. Chi square analysis, multiple logistic regression and multiple linear stepwise regression were used. Results The average age of the patients was 61.5 ± 12.6 （ range 16 - 87）. Days of hospitalization, hours of ICU stay and ventilation of obese group were significantly longer than that of normal group respectively（ P 〈 0. 001 ）. Incidence of renal failure, dialysis requiry, atrial fibrillation also positively associated with obesity. However, we did not find a statistically significant correlation between obesity and all-cause death and most complications. Conclusions Obesity does not increase the death rate of cardiac surgery and neither does most complications, but it increases the expense of patients and could potentially raise risks of the cardiac surgery.
