Disease category
Atherosclerosis is a disease in which arteries narrow due to the buildup of plaque containing cholesterol, fat, blood components, calcium, etc., on the inner walls of the arteries.
Core mechanism
Lifestyle habits related to arterial damage, diseases such as hypertension, hypercholesterolemia, and diabetes, inflammatory diseases, and genetic factors may be involved in its development.
Main causes · related factors
As plaque grows and hardens, the arterial lumen narrows, reducing the flow of oxygen-rich blood, and if plaque ruptures, a thrombus may form and block the blood vessel.
Representative patterns
Depending on the affected vessels, symptoms such as angina, dyspnea, transient ischemic attack, leg pain during walking, cognitive or visual abnormalities, and abdominal pain and weight loss after meals may occur.
Individual differences
Risk may vary depending on age, smoking/tobacco use, a diet high in saturated fats, family history, hypertension, diabetes, metabolic syndrome, and inflammatory diseases.
Diagnosis
In the early stages, there may be no symptoms, and symptoms may manifest when oxygen demand increases due to physical or emotional stress; if it progresses, it can lead to complications such as myocardial infarction, stroke, and limb loss.
Management
Diagnosis is made by comprehensively evaluating medical history, family history, lifestyle habits, risk factors, physical examination, blood tests, and cardiovascular-related tests.
Treatment/Research Status
The condition may be asymptomatic, and symptoms and test results vary depending on the involved vessels and the degree of blood flow restriction; therefore, the extent and risk of the disease should not be determined by a single symptom or test alone.
Read Evidence
Management is individualized by combining lifestyle habits that benefit heart health, management of risk factors and comorbidities, and, when necessary, drug therapy and procedures or surgery to restore blood flow.
Key Precautions
The goal of treatment is to reduce the risk of plaque and thrombosis, preserve blood flow, and prevent complications; specific treatments are determined according to the involved site, degree of blood flow restriction, and comorbidities.

At a Glance

Atherosclerosis is a disease in which arteries narrow due to the buildup of plaque containing cholesterol, fat, blood components, calcium, etc., on the inner walls of the arteries.

Depending on the affected vessels, symptoms such as angina, dyspnea, transient ischemic attack, leg pain during walking, cognitive or visual abnormalities, and abdominal pain and weight loss after meals may occur.

How the disease works

Lifestyle habits related to arterial damage, diseases such as hypertension, hypercholesterolemia, and diabetes, inflammatory diseases, and genetic factors may be involved in its development.

As plaque grows and hardens, the arterial lumen narrows, reducing the flow of oxygen-rich blood, and if plaque ruptures, a thrombus may form and block the blood vessel.

Variations in presentation among individuals

Risk may vary depending on age, smoking/tobacco use, a diet high in saturated fats, family history, hypertension, diabetes, metabolic syndrome, and inflammatory diseases.

The broad framework of diagnosis and management

In the early stages, there may be no symptoms, and symptoms may manifest when oxygen demand increases due to physical or emotional stress; if it progresses, it can lead to complications such as myocardial infarction, stroke, and limb loss.

Diagnosis is made by comprehensively evaluating medical history, family history, lifestyle habits, risk factors, physical examination, blood tests, and cardiovascular-related tests.

Current status of treatment

The condition may be asymptomatic, and symptoms and test results vary depending on the involved vessels and the degree of blood flow restriction; therefore, the extent and risk of the disease should not be determined by a single symptom or test alone.

Management is individualized by combining lifestyle habits that benefit heart health, management of risk factors and comorbidities, and, when necessary, drug therapy and procedures or surgery to restore blood flow.

The goal of treatment is to reduce the risk of plaque and thrombosis, preserve blood flow, and prevent complications; specific treatments are determined according to the involved site, degree of blood flow restriction, and comorbidities.

How to read clinical trials

Clinical trial registration only demonstrates the existence and design of a study and does not prove efficacy, safety, approval, or standard of care; therefore, it must be interpreted by distinguishing between the disclosure of status and results.

Points to verify during clinical consultations

In clinical practice, it is possible to identify symptoms and onset time, smoking habits, diet, exercise, blood pressure, blood glucose, lipids, family history, current medications, past cardiovascular/cerebrovascular events, necessary tests, and follow-up plans.
