Coronary Artery Disease

Coronary artery disease develops when the arteries that supply the heart become narrowed by atherosclerosis. It may cause chest discomfort, shortness of breath or no symptoms until the disease becomes more advanced. ^[1][2]

What is Coronary artery disease?

Reduced blood flow can cause angina during exertion, emotional stress or sometimes at rest. When a plaque ruptures and a clot forms, it may trigger a heart attack. ^[1][3]

What are the symptoms and what causes it?

Symptoms can include chest pressure, arm or jaw discomfort, shortness of breath, reduced exercise tolerance and sometimes nausea or sweating. Major risk factors include smoking, diabetes, high blood pressure, high cholesterol, family history and age. ^[1][2][3]

How is it diagnosed?

Evaluation may include ECG, blood tests, stress testing, echocardiography, CT coronary imaging or invasive angiography depending on urgency and symptom pattern. ^[1][2]

What are the treatment options?

Treatment often combines lifestyle changes, medications that reduce risk or symptoms and, in selected cases, procedures such as stenting or bypass surgery. The plan depends on disease severity and symptoms. ^[1][2][4]

Possible complications and when to seek medical care

Heart attack, arrhythmia, heart failure and sudden cardiac death are serious complications. New or worsening chest pain, especially at rest or with sweating and shortness of breath, is an emergency. ^[1][2][3]

What may help in daily life?

Risk-factor control matters even when symptoms are mild. The disease affects the whole cardiovascular system, not just the chest. ^[2][3]

Common mistakes during follow-up

Common mistakes include ignoring exertional chest discomfort and stopping heart medications because symptoms temporarily improve. ^[2][4]

FAQ

What is coronary artery disease?

Coronary artery disease is explained by its symptoms, causes, diagnosis and treatment plan. The most important step is matching the symptoms with the correct medical evaluation. ^[1][2]

When should I see a doctor for coronary artery disease?

Seek medical review if symptoms are persistent, worsening, recurrent or clearly affecting daily life. Urgent review is needed when warning signs or severe symptoms are present. ^[1][2]

Can coronary artery disease improve without treatment?

Some mild cases or symptom flares may settle, but not every condition should be watched at home. Improvement does not always mean the underlying problem has been resolved. ^[1][2]

How is coronary artery disease diagnosed?

Diagnosis usually starts with a medical history and examination, then moves to targeted tests depending on the symptom pattern and suspected cause. ^[1][2]

Why does follow-up matter?

Follow-up helps confirm the diagnosis, assess response to treatment and detect complications or recurrence earlier. ^[1][2]
