Physical Activity After Treatment for Symptomatic Peripheral Artery Disease

Area of Science:

• Vascular Medicine
• Rehabilitation Science

Background:

• The relationship between invasive treatments and physical activity in claudication patients is not well understood.
• Peripheral artery disease (PAD) affects physical function and quality of life.

Purpose of the Study:

• To investigate the association between invasive versus noninvasive treatment and physical activity levels at 12 months in patients with claudication.
• To examine the impact of changes in physical activity on health status.

Main Methods:

• A cohort of 656 claudication patients from US vascular clinics were categorized by treatment (invasive vs. noninvasive).
• Leisure time physical activity (LTPA), work-related physical activity (WRPA), and health status (PAQ SS) were assessed at baseline and 12 months.
• Multivariable regression models analyzed the association of treatment with physical activity and changes in physical activity with changes in health status.

Main Results:

• 29.9% of patients underwent invasive treatment.
• No significant association was found between invasive treatment and 12-month LTPA or WRPA.
• Increased LTPA was strongly associated with improved health status (PAQ SS) compared to persistent sedentary behavior.

Conclusions:

• Invasive treatment for claudication did not influence physical activity levels at follow-up.
• Increased physical activity, regardless of treatment type, is linked to significant health status improvements in PAD patients.
• Strategies to enhance physical activity may be crucial for improving outcomes in peripheral artery disease.
