Understanding Angina: What It Is, Symptoms, Diagnosis, & Treatment
Updated: Aug 11
Angina is a term often associated with heart health, but what exactly does it mean? Angina is not a disease itself but a symptom of an underlying heart condition, most commonly coronary artery disease. It occurs when the heart doesn’t get enough oxygen-rich blood, causing discomfort or pain in the chest.
At Highfield & District Medical Centre, we’re here to provide you with the information and support you need to manage heart health effectively.
What is Angina?
Angina is chest pain or discomfort caused by reduced blood flow to the heart. This can occur during physical activity, emotional stress, or even at rest, depending on the type of angina.
Types of Angina:
Stable Angina: Triggered by predictable activities like exercise or stress, and relieved by rest or medication.
Unstable Angina: More severe, occurs without warning, and may signal a heart attack.
Variant (Prinzmetal’s) Angina: Rare and caused by a spasm in the coronary arteries, often occurring at rest.
Signs and Symptoms of Angina
The symptoms of angina can vary, but common signs include:
Chest Pain or Discomfort: Often described as pressure, tightness, or heaviness in the chest.
Pain Radiating to Other Areas: Pain may spread to the arms, neck, jaw, shoulder, or back.
Shortness of Breath: Particularly during physical activity.
Nausea, Fatigue, or Dizziness: Sometimes accompanying chest discomfort.
If you experience severe or persistent chest pain, seek immediate medical attention by calling 000.
Who is More Likely to Experience Angina?
Several risk factors increase the likelihood of developing angina, including:
Age: Men over 45 and women over 55 are at greater risk.
Family History of Heart Disease: Genetic predisposition can play a role.
Lifestyle Factors: Smoking, poor diet, and lack of physical activity.
Existing Conditions: High blood pressure, diabetes, or high cholesterol.
How is Angina Diagnosed?
Doctors use a variety of methods to diagnose angina:
Medical History and Symptoms: Discussing your symptoms and risk factors.
Physical Examination: Checking for signs of heart strain.
Diagnostic Tests: These may include:
Electrocardiogram (ECG): To measure heart activity.
Stress Test: Monitoring your heart during exercise.
Coronary Angiography: Using imaging to view blood flow in the arteries.
Treatment for Angina
The goal of treatment is to reduce symptoms and prevent heart attacks. Treatment options include:
Lifestyle Changes:
Quit smoking and avoid second hand smoke.
Maintain a heart-healthy diet rich in fruits, vegetables, and whole grains.
Exercise regularly as advised by your doctor.
Manage stress effectively through relaxation techniques.
Medications:
Nitroglycerin: To relieve chest pain.
Beta-Blockers and Calcium Channel Blockers: To improve blood flow.
Statins: To lower cholesterol levels.
Medical Procedures:
Angioplasty and Stent Placement: To open narrowed arteries.
Coronary Artery Bypass Surgery: For severe cases of blocked arteries.
Myths About Angina Debunked
Myth: Angina is a heart attack.
Truth: While angina indicates reduced blood flow to the heart, it is not the same as a heart attack. However, it is a warning sign that should not be ignored.
Myth: Only older adults get angina.
Truth: While age is a factor, younger individuals with risk factors like diabetes or smoking can also develop angina.
Myth: If the pain goes away, it’s not serious.
Truth: Even if symptoms subside, angina indicates an underlying issue that needs medical attention.

Regular Check-Ups: Schedule routine visits with your doctor to monitor heart health.
