Insights

Peri-ungueal capillaroscopy (PUC) detects early signs of atherosclerosis in microcirculation. Lesions are not specific but indicate disease severity and progression, aiding diagnosis.

Area of Science:

  • Vascular Biology
  • Dermatology
  • Cardiology

Context:

  • Atherosclerosis impacts major vessels and microcirculation, leading to distal ischemia.
  • Assessing microvascular changes is crucial for understanding disease consequences.

Purpose:

  • To evaluate lesions from atherosclerosis using peri-ungueal capillaroscopy (PUC).
  • To determine the diagnostic and prognostic value of PUC in atherosclerotic disease.

Summary:

  • 210 patients with atherosclerosis risk factors or disease were studied using PUC.
  • Patients were grouped by lesion severity observed via PUC.
  • Capillaroscopic findings, while non-specific, correlate with disease severity and appear early.

Impact:

  • PUC can identify early microcirculatory changes in atherosclerosis.
  • The severity of capillaroscopic lesions reflects the overall atherosclerotic burden.
  • This non-invasive technique may aid in early diagnosis and prognosis assessment.

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

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 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...

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...
