Atherosclerosis

Atherosclerosis is buildup of lipid-rich plaques and inflammatory tissue in arterial walls. It can narrow blood supply or produce acute events after plaque disruption.

At a glance

Quick facts

Category
Cardiovascular disorders
What it is
Atherosclerosis is buildup of lipid-rich plaques and inflammatory tissue in arterial walls.
Typical presentation
Often silent for years; symptoms depend on the affected artery, such as angina, leg pain on walking or transient neurological symptoms.
Assessment
Risk factors and organ-specific assessment guide cholesterol tests and imaging when clinically indicated.
Treatment approach
Smoking cessation, healthy activity, lipid lowering and control of blood pressure and diabetes reduce vascular risk.
Key safety concern
New stroke-like symptoms, chest pain or signs of sudden limb ischemia need immediate emergency assessment.

Overview

Atherosclerosis is buildup of lipid-rich plaques and inflammatory tissue in arterial walls. It can narrow blood supply or produce acute events after plaque disruption.

Symptoms and presentation

Often silent for years; symptoms depend on the affected artery, such as angina, leg pain on walking or transient neurological symptoms.

CLINICAL FEATURES

Presentation and warning signs

The pattern varies and cannot replace an individual assessment.

Clinical overview
Presentation
  • Often silent for years
  • symptoms depend on the affected artery
  • such as angina
  • leg pain on walking or transient neurological symptoms
Clinical assessment
  • Risk factors and organ-specific assessment guide cholesterol tests and imaging when clinically indicated
  • Interpret results with history and examination
When to seek urgent care
  • New stroke-like symptoms, chest pain or signs of sudden limb ischemia need immediate emergency assessment.

Emergency symptoms and clinical severity should be assessed locally.

Clinical assessment and diagnosis

Risk factors and organ-specific assessment guide cholesterol tests and imaging when clinically indicated. Routine scans are not necessary for everyone.

ASSESSMENT

How the clinical assessment proceeds

Exact investigations depend on the clinical context.

Clinical workflow
1Define the symptom patternOften silent for years; symptoms depend on the affected artery, such as angina, leg pain on walking or transient neurological symptoms.
2Assess disease or alternative causesRisk factors and organ-specific assessment guide cholesterol tests and imaging when clinically indicated. Routine scans are not necessary for everyone.
3Discuss care and monitoringSmoking cessation, healthy activity, lipid lowering and control of blood pressure and diabetes reduce vascular risk. Procedures are reserved for selected symptomatic disease.

Treatment and management

Smoking cessation, healthy activity, lipid lowering and control of blood pressure and diabetes reduce vascular risk. Procedures are reserved for selected symptomatic disease.

Treatment & care hub

Elements of care

Individual treatment is based on diagnosis, comorbidities and clinician assessment.

Management overview
