问题单项选择题

一心肌梗死患者经治疗后病情稳定，准备出院。现考虑根据代谢当量(metabolic equivalent，MET)对该患者进行日常生活活动与职业活动指导。确定患者的安全运动强度之后

建议该患者日常活动峰值强度不可超过峰值MET的（）

A．35%～50%

B．45%～55%

C．50%～65%

D．50%～60%

E．70%～80%

答案

参考答案：E

解析：

心血管患者不可能进行所有日常生活活动或职业活动，因此需要在确定患者的安全运动强度之后，根据MET选择合适的活动。职业活动(每天8小时)的平均能量消耗水平不应该超过患者峰值MET的40%，峰值强度不可超过峰值MET的70%～80%。
