Is There an Association Between Timed Up and Go Test Performance Results and Directly Measured Peak Oxygen Consumption in Patients with Heart Disease?

This Short Editorial is referred by the Research article "Prediction of Peak Oxygen Consumption in Patients with Heart Disease Based on Performance on the Timed Up and Go Test".
Functional capacity, the ability to perform daily activities independently, is commonly assessed using standardized tests like the 6-minute walk test, Timed Up and Go Test (TUGT), and one-minute sit-to-stand test. However, the gold standard for evaluating functional or cardiorespiratory capacity is cardiopulmonary exercise testing (CPET), which measures peak oxygen consumption (VO2peak). CPET involves gradually increasing exercise intensity until exhaustion or symptom onset.
Numerous studies consistently demonstrate a strong inverse association between VO2peak and cardiovascular events, cardiovascular mortality, and all-cause mortality,, underscoring the pivotal role of functional capacity in the context of cardiovascular diseases. Moreover, in heart failure, regardless of ejection fraction status, poor performance on the 6-minute walk test has been linked to elevated risks of all-cause mortality and heart failure.
