Peripheral Artery Disease III: Interprofessional Care01:27

Peripheral Artery Disease III: Interprofessional Care

121
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...

Peripheral Artery Disease I: Introduction

158
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...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

174
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...

Exercise and Cardiovascular Response01:20

Exercise and Cardiovascular Response

3.6K
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Summary

Many older adults do not respond well to exercise therapy for peripheral artery disease. Over a third showed no improvement in walking distance, highlighting the need for personalized exercise programs.

Area of Science:

  • Gerontology
  • Exercise Physiology
  • Cardiovascular Disease Research

Background:

  • Nonresponse to exercise is well-documented in young athletes but understudied in older adults undergoing aerobic exercise interventions.
  • Peripheral artery disease (PAD) affects older adults, impacting physical function and quality of life.

Purpose of the Study:

  • To determine the prevalence of nonresponse and poor response to a 12-week supervised exercise therapy program in older adults with PAD.
  • To analyze response patterns in functional and quality of life outcomes.

Main Methods:

  • A cohort of 44 older adults (mean age 72.3 years, 47.7% female) with PAD participated in 12 weeks of supervised exercise therapy.
  • Outcomes included objective measures of physical function (e.g., walking distance) and patient-reported functional and quality of life measures.
  • Response was categorized as nonresponse (no change/decline) or poor response (lack of clinically meaningful improvement).

Main Results:

  • The prevalence of nonresponse in walking distance was 31.8%.
  • The prevalence of poor response in walking distance was 43.2%.
  • Similar nonresponse and poor response patterns were observed across objective and patient-reported physical function measures. All participants improved in at least one outcome, but only two improved in all outcomes.

Conclusions:

  • A significant proportion of older adults with PAD do not achieve meaningful benefits from standard supervised exercise therapy.
  • Individual variability in response suggests a need for tailored exercise programming.
  • Further research should identify modifiable predictors of exercise response to optimize therapeutic benefits for individuals with PAD.
