Summary
Smartphone-delivered home-based exercise therapy (HBET) shows promise for peripheral arterial disease (PAD) patients. This pilot study explores the feasibility of mobile-first HBET, potentially improving accessibility and public health benefits for PAD management.
Area of Science:
- Cardiovascular Medicine
- Rehabilitation Science
- Digital Health
Background:
- Supervised exercise therapy (SET) is recommended for symptomatic peripheral arterial disease (PAD) but faces low patient adoption.
- Home-based exercise therapy (HBET) via smartphones may increase access, yet its feasibility, particularly in low-resource settings, is underexplored.
Purpose of the Study:
- To assess the feasibility of a smartphone-enabled home-based exercise therapy (HBET) program for patients with symptomatic PAD.
- To evaluate the effectiveness of mobile-first HBET compared to walking advice on exercise capacity.
Main Methods:
- A pilot randomized trial comparing smartphone-enabled HBET with walking advice in inner-city PAD patients.
- Participants used a smartphone app for daily reminders and education, with weekly phone coaching.
- Physical activity was monitored using Fitbit, and the primary outcome was the change in 6-minute walking test (6MWT) distance at 12 weeks.
Main Results:
- The pilot enrolled 15 patients (mean age 66.1 years, 60% female, 87% Black) with symptomatic PAD.
- Baseline ABI averaged 0.86, and 6MWT was 363.5m.
- Enrollment is ongoing to reach a target of 50 participants by December 2020.
Conclusions:
- This trial provides preliminary evidence for a home-based, mobile-first approach to structured exercise rehabilitation for PAD.
- Smartphone-enabled HBET offers potential for greater accessibility than traditional center-based programs.
- If proven effective, this approach could yield significant public health benefits for PAD management.

01:27Peripheral Artery Disease III: Interprofessional Care
178
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

01:30Peripheral Artery Disease I: Introduction
223
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

The nursing management of a patient with peripheral artery disease (PAD) begins with a thorough assessment of the patient’s health history and clinical manifestations.AssessmentHealth History: Evaluate the patient’s history of hypertension, hyperlipidemia, family history of cardiovascular issues, and lifestyle factors such as dietary patterns, smoking, and physical activity.Physical Examination:Assess the affected extremity for decreased or absent peripheral pulses,...

257
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Nursing management for a patient with arteriosclerosis involves a comprehensive approach focusing on lifestyle modification, disease monitoring, education, and symptomatic care. Here is an overview of effective nursing strategies:Assessment and Monitoring: Initial and ongoing assessments are crucial. Nurses must document the patient's medical history, including any hypertension, diabetes, hyperlipidemia, and other cardiovascular diseases. Assessments also cover family history and lifestyle...
