无氧阈值下代谢当量及年龄、性别、体重指数对冠心病患者心肺运动试验的影响

The heart and lung exercise trial of influence on age、gender、body mass index metabolite equivalents under the anaerobic threshold for coronary heart disease Patient

目的探讨中国冠心病患者无氧阈(anaerobic threshold,AT)值下的代谢当量(metabolite equivalents,METs),以及年龄、性别及体重指数(body mass index,BMI)对其心肺运动试验的影响。方法选取本院2015年9月至2017年1月收治的冠心病患者316例,其中男性161例,女性155例,均进行运动心肺评估。将患者按年龄分为50岁以内、50~59岁、60~70岁、70岁以上年龄组,比较各组之间AT下的METs与最终METs值的差异,分析BMI与AT下METs的相关性。结果各年龄组内男性及女性最终METs值及AT下METs值差异无显著性。各年龄组间相比最终METs值差异有显著性,并与年龄呈负相关,所有年龄组AT下METs值均差异无显著性。男性与女性的最终METs值及AT下METs值差异均无显著性。BMI与最终METs值呈负相关,但与AT下METs值无关。结论冠心病患者无论是男性还是女性AT下代谢当量均较低,平均约3.0~4.5,AT下METs值与年龄、性别及BMI均无关,最终METs值与性别无关,但与年龄呈负相关,年龄越高,最终METs值越小;与BMI值呈负相关,BMI值越高,最终METs值越大。

Objective Probe metabolite equivalents, age, gender and body mass index for Chinese coronary heart disease under anaerobic threshold, considering the influence of heart and lung in exercise trials. Method 316 patients （155 women and 161 men） in our hospital conduct heart and lung evaluation from Sep. 2015 to Jan. 2017. Patients were randomly divided into 4 groups aging below 50、50-59、60-70 and over 70 to compare the difference of metabolite equivalents between anaerobic threshold and final stage. We also calculate the relation between body mass index and metabolite equivalents under anaerobic threshold. Result All the people have lower average value as well as no difference between final metabolite equivalents and metabolite equivalents under anaerobic threshold. However, there is no relation about metabolite equivalents under anaerobic threshold. Conclusion Patients with coronary heart disease no matter the male or the female have low average value about 3.0-4.5 under anaerobic threshold.The metabolite equivalents ender anaerobic threshold have no relationship with age,sex and bodymass index.The final metabolite equivalents have no relationship with the sex,but show negative correlation with the age.The result also suggested that body mass index and metabolite equivalents show negative correlation. The higher body mass index is, the lower metabolite equivalents is.
