: Is the Treadmill Test Safe When Performed Using a Surgical Mask and
Are Its Results Reliable In Terms Of Diagnosis?
Abstract
Objective: Mask use has a substantial role in reducing the spread of
COVID-19 in confined spaces. However, the use of masks is controversial
in cases where intense effort is required, such as the treadmill
exercise test. Since the majority of subjects undergoing this test are
elderly individuals with comorbidities, the safety and reliability of
the test are critical matters that must be elucidated in the
post-COVID-19 era. In this study, the safety of the treadmill exercise
test performed using a mask and the diagnostic reliability of the test
were questioned. Method: In our clinic, before March 11, 2020, treadmill
exercise tests were performed without a mask; whereas, after this date,
patients were supplied with a standard surgical mask during the test.
These two groups were compared with regard to various characteristics to
assess diagnostic reliability and safety. Results: The diagnostic
reliability and the safety of the stress test performed with a mask was
found to be similar to that of tests performed without a mask. However,
we noted that shortness of breath was more common in the mask-wearing
group. Conclusion: The treadmill exercise test performed by wearing
surgical masks is safe and its results are reliable for diagnosis.
