Insights

The COVID-19 pandemic impacted endovascular therapy (EVT) volumes for peripheral artery disease (PAD) differently based on limb severity. Chronic limb-threatening ischemia (CLTI) volumes remained stable, while intermittent claudication volumes decreased.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Public Health

Background:

  • The COVID-19 pandemic's effect on endovascular therapy (EVT) for symptomatic peripheral artery disease (PAD) in Japan remains unexamined.
  • Understanding these impacts is crucial for healthcare planning and patient management.

Purpose of the Study:

  • To systematically evaluate the impact of the COVID-19 pandemic on EVT procedure volumes in Japan.
  • To differentiate the pandemic's effects based on the severity of PAD.

Main Methods:

  • Analysis of nationwide EVT procedural registry data from Japan (2012-2023).
  • Comparison of EVT volumes for chronic limb-threatening ischemia (CLTI) and intermittent claudication before, during, and after the pandemic.

Main Results:

  • EVT volumes for CLTI remained stable throughout the pandemic period and beyond.
  • EVT volumes for intermittent claudication showed a decrease below forecasted levels starting in 2020.
  • This reduction in intermittent claudication EVT volume persisted even after the main pandemic phase.

Conclusions:

  • The COVID-19 pandemic's influence on EVT volumes for PAD is not uniform.
  • Limb severity is a key factor determining the impact of the pandemic on EVT utilization.
  • Intermittent claudication patient volumes experienced a sustained decline post-pandemic, warranting further investigation.

Peripheral Artery Disease I: Introduction

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 Artery Disease IV: Nursing Management

 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,...

Peripheral Artery Disease III: Interprofessional Care

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 Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

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...

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...
