Table vs Unstable Angina: Key Differences

Angina is a warning signal from your heart that it is not getting enough oxygen-rich blood. It often feels like pressure, heaviness, or squeezing pain in the chest. While angina itself is not a heart attack, it can be a strong indicator of underlying heart disease. Among the different types of angina, stable angina and unstable angina are the most commonly discussed, and understanding their differences is very important for timely diagnosis and treatment.

What is Stable Angina?

Stable angina is the most common type of angina. It typically develops when your heart works harder than usual, such as during exercise, climbing stairs, or after emotional stress.

Key features of stable angina:

• The chest discomfort follows a predictable pattern.
• Pain usually lasts a few minutes and goes away with rest.
• Medication such as nitroglycerin often helps relieve the pain.
• It is a signal that the heart arteries are narrowed but not suddenly blocked.

Stable angina is manageable, but it requires medical attention because it indicates coronary artery disease, which can worsen if left untreated.

What is Unstable Angina?

Unstable angina is a more serious and unpredictable condition. It can happen even when you are at rest or sleeping. It is considered a medical emergency because it often means that blood flow to the heart is severely reduced and could lead to a heart attack.

Key features of unstable angina:

• Chest pain occurs without a predictable pattern.
• It may happen more frequently and last longer.
• Pain may not fully improve with rest or medication.
• Symptoms may spread to the arm, jaw, neck, or back.

Unstable angina signals a higher risk of heart attack. Immediate medical evaluation is essential.

Table Comparing Stable vs Unstable Angina

Symptoms You Should Not Ignore

Both stable and unstable angina have overlapping symptoms, but unstable angina tends to be more alarming.

Common symptoms include:

• Chest pain or pressure that may feel like heaviness
• Discomfort spreading to arms, shoulders, jaw, or back
• Shortness of breath
• Nausea or dizziness
• Excessive sweating

If your chest pain becomes more frequent, lasts longer, or occurs even at rest, it is important to seek emergency medical help immediately.

Causes and Risk Factors

Both conditions are linked to coronary artery disease caused by plaque buildup in the arteries. When plaque narrows or suddenly blocks blood flow, angina develops.

Risk factors include:

• High blood pressure
• High cholesterol
• Diabetes
• Smoking
• Lack of physical activity
• Obesity
• Family history of heart disease
• Stress and poor lifestyle habits

Managing these risk factors with regular check-ups, healthy diet, exercise, and medical care can reduce the chance of angina progressing.

Diagnosis of Angina

Doctors use various tests to diagnose angina and identify whether it is stable or unstable. These may include:

Electrocardiogram (ECG): Records electrical activity of the heart.

Blood tests: To check heart damage markers.

Stress tests: Assess heart function during exertion.

Echocardiogram: Ultrasound imaging of the heart.

Coronary angiography: Identifies blocked or narrowed arteries.

Treatment Options

Treatment differs for stable and unstable angina depending on the severity.

Stable angina treatment may include:

• Lifestyle changes like quitting smoking, healthy eating, and exercise.
• Medications to improve blood flow and reduce workload on the heart.
• Procedures such as angioplasty or bypass surgery if needed.

Unstable angina treatment requires urgent care:

• Immediate hospitalization.
• Medications to dissolve clots or prevent new ones.
• Coronary interventions to restore blood flow.

Prevention Tips

You can lower your risk of developing unstable angina by controlling the risk factors that cause stable angina.

Simple steps include:

• Eat a balanced diet rich in fruits, vegetables, and whole grains.
• Exercise regularly as advised by your doctor.
• Avoid smoking and limit alcohol.
• Manage stress effectively.
• Keep blood pressure, cholesterol, and diabetes under control.
• Go for regular health check-ups.
