Cardiology>>>>>Cardiac Rehabilitation
Question 3#

You are reviewing a 60-year-old patient in clinic after a recent NSTEMI. They have not yet completed their cardiac rehabilitation programme and are asking for advice about ongoing physical activity. They have been looking online and have come across articles that say they should exercise at about 6 ‘METs’. 

They ask you to explain what a MET is and if it means that they have to jog to keep healthy.

A) 1 MET, or metabolic equivalent of task, is equivalent to the resting metabolic rate when sitting quietly, and has a conventional reference value of 3.5 mL O2/kg/min which is equal to 1 kcal/kg/h
B) 1 MET, or metabolic equivalent of task, is equivalent to the resting metabolic rate when sleeping, and has a conventional reference value of 3.5 ml O2/kg/min which is equal to 1 kcal/kg/h
C) 1 MET, or metabolic equivalent of task, is equivalent to the resting metabolic rate when sitting quietly, and has a conventional reference value of 6.5 mL O2/kg/min which is equal to 1 kcal/kg/h
D) 1 MET, or metabolic equivalent of task, is equivalent to the resting metabolic rate when sleeping, and has a conventional reference value of 6.5 mL O2/kg/min which is equal to 1 kcal/kg/h
E) The METs are a baseball team from New York that have sponsored an exercise programme for cardiac patients

Correct Answer is A

Comment:

A metabolic equivalent is a way of expressing the metabolic energy requirements of a task as multiples of the resting metabolic rate (RMR). 1 MET is equivalent to the RMR when sitting quietly, and has a conventional reference value of 3.5 mL O2/kg/min which is equal to 1 kcal/kg/h.
