About Coronary Intervention (Angiography)

Coronary Angiography is a diagnostic procedure that helps doctors visualize the blood vessels of the heart (coronary arteries). It uses a special contrast dye and X-ray imaging to detect any blockages or narrowing in the arteries that supply blood to the heart.

When necessary, this procedure can be followed by a Coronary Intervention (Angioplasty or Stent Placement) — a treatment to open blocked arteries and restore normal blood flow to the heart muscle.

🔍 Purpose of Coronary Angiography

Doctors recommend angiography when you have:

-Chest pain (angina) or shortness of breath

-Abnormal ECG or stress test results

-A history of heart attack or heart disease

-Risk factors such as diabetes, high blood pressure, or high cholesterol

-To evaluate the condition of coronary arteries before heart surgery

⚙️ How the Procedure is Performed

1.Preparation:

You will be asked not to eat or drink for a few hours before the procedure. An IV line is inserted, and mild sedation may be given.

2.Catheter Insertion:

A thin tube called a catheter is inserted through an artery in your groin (femoral artery) or wrist (radial artery).

3.Dye Injection:

A contrast dye is injected through the catheter into the coronary arteries.

4.X-ray Imaging:

A special X-ray machine (fluoroscopy) captures real-time images showing the flow of blood through the coronary arteries.

5.Intervention (if needed):

If a blockage is found, the cardiologist may immediately perform an angioplasty — using a small balloon to open the blocked area — and may place a stent to keep the artery open.
