Key result
Self-reported vigorous physical activity on the IPAQ-L correlated with predicted maximal oxygen uptake (p=0.025), and moderate activity correlated with heart rate reserve (p=0.005) on CPET.
Why the study?
Current guidelines emphasize regular aerobic exercise in cardiovascular disease prevention, but the utility of the International Physical Activity Questionnaire Long Form for physical activity quantification in patients with heart failure with reduced ejection fraction needed evaluation.
Does the IPAQ-L questionnaire correlate with CPET parameters for quantifying physical activity in patients with HFrEF undergoing cardiac rehabilitation?

Does the IPAQ-L questionnaire correlate with CPET parameters for quantifying physical activity in patients with HFrEF undergoing cardiac rehabilitation?
p-value: p=0.025
The IPAQ-L questionnaire correlates with some CPET parameters and can be used to evaluate physical activity levels in cardiac rehabilitation, though it cannot replace CPET.
IPAQ-L may aid activity assessment in HFrEF rehab; leaves open substitution for CPET.
(1) Background: Current guidelines emphasize the importance of regular moderate and/or high intensity aerobic exercises in cardiovascular disease prevention. Our study aimed to evaluate the utility of the International Physical Activity Questionnaire Long Form (IPAQ-L) for its physical activity (PA) quantification in patients with heart failure with reduced ejection fraction. (2) Methods: We conducted a cross-sectional study of 110 patients aged between 34 and 69 years admitted to the Cardiovascular Rehabilitation Clinic. All patients underwent a clinical examination, blood tests, a cycle ergometer exercise stress test and individual assessment of their weekly PA level using the IPAQ-L. (3) Results: Obesity, hypertension and type 2 diabetes were highly prevalent in our study group but did not influence the IPAQ-L results. In terms of physical performance, moderate intensity was the most common level of intensity found in our study group. Regarding the data on the relationship between the IPAQ-L questionnaire and cardiopulmonary exercise testing (CPET) parameters, vigorous PA was correlated with predicted maximal oxygen uptake (p = 0.025) and moderate PA, in addition to walking, were correlated with heart rate reserve (p = 0.005 and p = 0.009, respectively). (4) Conclusions: IPAQ-L can be used for the evaluation of individual PA levels within a cardiovascular rehabilitation program, but cannot substitute for the importance and utility of CPET.

Manta et al. (2021) conducted a cross-sectional in Heart failure with reduced ejection fraction (n=110). International Physical Activity Questionnaire Long Form (IPAQ-L) vs. Cardiopulmonary exercise testing (CPET) was evaluated on Relationship between the IPAQ-L questionnaire and cardiopulmonary exercise testing (CPET) parameters (p=0.025). Self-reported vigorous physical activity on the IPAQ-L correlated with predicted maximal oxygen uptake (p=0.025), and moderate activity correlated with heart rate reserve (p=0.005) on CPET.
