慢性心力衰竭患者体质量指数改变的临床意义

Clinical significance of the body mass index changes of chronic heart failure patients

目的观察慢性心力衰竭患者治疗前后体质量指数(body mass index,BMI)改变情况,明确其改变的临床指导意义。方法共纳入65例慢性心力衰竭患者,患者入院次日晨空腹测量其体质量、身高,计算BMI,其后每日测量体质量,直至病情好转出院。计算患者入院后BMI最高值与最低值的差值、观察并记录患者入院时的临床表现,如心功能分级、水肿程度。结果患者在出院时BMI值显著下降(t=9.083,P<0.001)。心功能Ⅳ级患者,BMI差值显著高于Ⅱ、Ⅲ级患者(Z=3.655,P<0.001;Z=4.562,P<0.001);重度水肿患者BMI差值高于轻、中度水肿患者,同时三者均高于无水肿患者。结论 BMI的变化可作为衡量心力衰竭严重程度的指标,有临床应用价值。

Objective To observe changes of th e body mas s index （BMI ） of chronic h e a r tfailure （CHF） pat ients after their therapy and to clarity its clinic significance. Methods Sixty-fivepatients with CHF were measured their body weight and height to calculate BMI during their hospi tal ization. The clinical manifestations such as heart function grade and edema degree were recorded at their admission. Results T h e BMI decreased sign if ic an tly a t th e i r disch arg e = 9. 0 8 3, P 〈0. 001） . The gap between the highest and lowest BMI of pat ients with W-grade hear t function was significantly higher than that of patients with [[-and H-grade heart function （Z = 3. 655 ？F〈 0. 001; Z = 4. 562, P 〈0. 0 0 1 ） . F o r p a t ien ts with severe e d ema ,th e gap was h ig he r th an th o se of mild and medium edema, and th a t of th e p a t ien ts of edema was h ig h e r th an th a t of people w i th o u tedema. Conclusions T h e change of BMI can used to re fle ct th e h e a r t function of CHF p atien ts .
