Angina Diagnosis: Essential Tests and Procedures

When experiencing symptoms of angina, it's crucial to undergo specific medical tests to confirm the diagnosis and understand the underlying causes. These diagnostic tools help doctors evaluate heart function and identify any blockages or abnormalities in the coronary arteries.

Common Diagnostic Tests for Angina

1. Electrocardiogram (ECG)

An ECG is one of the first tests performed when angina is suspected. It records the electrical activity of the heart and can detect changes in the ST-T wave segments during and after an angina episode. These dynamic changes help establish a link between the symptoms and coronary artery disease.

2. Coronary CT Angiography

This non-invasive imaging test provides detailed pictures of the coronary arteries. It helps detect any narrowing or blockages in the blood vessels that may be causing chest pain. Coronary CT angiography is especially useful for patients with unclear symptoms or inconclusive ECG results.

3. Exercise Stress Test

During a treadmill or stationary bike stress test, your heart's response to physical activity is monitored through continuous ECG readings. It can reveal ST-T wave changes that occur when the heart muscle isn't receiving enough oxygen-rich blood. However, this test may not be suitable for patients with frequent or severe angina episodes due to potential risks.

4. Coronary Angiogram

Considered the gold standard for diagnosing angina, a coronary angiogram is an invasive procedure that provides the most accurate view of the heart's blood vessels. A special dye is injected into the coronary arteries, allowing doctors to see any blockages or narrowing using real-time X-ray imaging.

Each of these diagnostic tools plays a vital role in confirming angina and determining the best course of treatment. If you experience recurring chest pain, consult a cardiologist to discuss which tests are most appropriate for your condition.
