Physical work capacity was evaluated by a multistage bicycle exercise test in 29 patients, 22 men and seven women aged 35-61 years (mean 49) with alcoholic liver cirrhosis and in a sex- and age-matched control group. The maximal work load was reduced in the patient group, mean 122 vs. 186 watts in men (P less than 0.001), and 60 vs. 119 watts in women (P less than 0.005). Resting heart rate was higher in patients (91 vs. 78 beats X min-1, P less than 0.005), and the maximal heart rate was lower (159 vs. 170 beats X min-1, P less than 0.001) compared with controls. Thirteen of 29 (45%) patients compared with 5 of 29 (17%) control subjects had an increase in left ventricular ejection fraction of less than or equal to 5% during exercise (P less than 0.05). The present results suggest that an impaired capacity of the cardiac function to respond adequately to physical stress may at times contribute to the reduced physical work capacity seen in patients with alcoholic liver cirrhosis.
对29例年龄在35 - 61岁(平均49岁)的酒精性肝硬化患者(22名男性和7名女性)以及性别和年龄匹配的对照组进行多级自行车运动试验,以评估其体力工作能力。患者组的最大工作量降低,男性平均为122瓦,对照组为186瓦(P < 0.001);女性平均为60瓦,对照组为119瓦(P < 0.005)。与对照组相比,患者静息心率较高(91次/分钟 vs. 78次/分钟,P < 0.005),最大心率较低(159次/分钟 vs. 170次/分钟,P < 0.001)。29例患者中有13例(45%)与29例对照组中的5例(17%)相比,运动期间左心室射血分数增加小于或等于5%(P < 0.05)。目前的结果表明,心脏功能对身体应激做出充分反应的能力受损有时可能导致酒精性肝硬化患者体力工作能力下降。
