Key result
Physical activity tolerance clusters HF patients into 3 distinct groups differing in NYHA class and BNP.
Why the study?
The study aimed to classify physical activity in patients with heart failure categorized as NYHA class I or II.

How can physical activity and self-care behavior be classified in patients with NYHA class I or II heart failure?
Patients with mild heart failure can be classified into three distinct groups based on physical activity tolerance and self-management, highlighting the need for tailored patient instruction.
This study aimed that we were classification of physical activity in patients with heart failure categorized as New York Heart Association (NYHA) class I or II. We were a survey using a researcher- administered questionnaire, SF-8, the Specific Activity Scale (SAS), and the Scale to Measure Self-Care Behavior of Patients with Heart Disease. We included 70 patients who were treated in the Department of Cardiovascular Medicine at Hospital A. Regarding patient characteristics and clinical information after the cluster analysis, there were significant differences in the NYHA class (p = 0.001), BNP level (p = 0.012), self-management of medication adherence (p = 0.000), and exercise habits (p = 0.005). We summarized characteristics of each group as follows : Group A showed high tolerance to physical activity and near-perfect self-management; Group B showed moderate tolerance to physical activity but was not willing to commit to daily exercise and self-management; and Group C showed low tolerance to physical activity and often requested others to handle medication management. We needed that tolerance to physical activity and proposals for tailored instruction according to patient conditions, and needed that instructions tailored to the characteristics of heart failure patients in groups A-C.

Doi et al. (2020) conducted a cross-sectional in Chronic heart failure (NYHA class I or II) (n=70). Physical activity tolerance was evaluated on Classification of physical activity tolerance using hierarchical cluster analysis of Specific Activity Scale (SAS) scores. Cluster analysis based on physical activity tolerance classified heart failure patients into three distinct groups that differed significantly in NYHA class (p=0.001), BNP level (p=0.012), medication adherence (p<0.001), and exercise habits (p=0.005).
