Understanding Coronary Angiography: A Vital Test for Heart Health
Coronary angiography is an important diagnostic tool used to assess the condition of your heart’s blood vessels. This test is primarily conducted to detect blockages or narrowing of the coronary arteries, which can lead to serious cardiac conditions, including heart attacks.
What is Coronary Angiography?
Coronary angiography is a procedure that uses X-rays and a special dye to examine the blood vessels in the heart. It’s a part of a broader family of tests called cardiac catheterization, where a catheter (a small, flexible tube) is inserted into the arteries to monitor or treat cardiovascular conditions.
This test is most often used when coronary artery disease (CAD) is suspected, as it provides clear, real-time images of any narrowing or blockages in the coronary arteries. In some cases, angioplasty or stent placement may be performed during the angiography to open a blocked artery, improving blood flow to the heart.
Why is Angiography Needed?
Coronary angiography is commonly performed in the following situations:
- Diagnosing coronary artery disease (CAD): The procedure identifies narrowing or blockages in the coronary arteries caused by a buildup of plaque, a condition known as atherosclerosis.
- Following a heart attack, angiography can evaluate the extent of damage caused by the blocked blood supply to the heart.
- Diagnosing and planning treatments for angina: This is chest pain caused by restricted blood supply to the heart.
- Planning interventional procedures: For example, coronary angioplasty, which widens narrowed or blocked arteries, or the placement of a stent to maintain blood flow.
Coronary angiography is also used to assess congenital heart diseases, heart valve issues, or heart failure.
It is usually done after non-invasive tests, such as an electrocardiogram (ECG), echocardiogram, or stress test, have indicated the possibility of coronary artery disease. The angiogram assists doctors in making a more precise diagnosis and determining the most effective treatment plan.
How Does a Coronary Angiogram Work?
At TX Hospital, one of the leading Hyderabad heart hospitals, the procedure is typically performed in a specialized room called the catheterization laboratory (or cath lab). Steps involved in the technique include:
- Preparation: Before the test, patients are asked to fast for several hours. An intravenous (IV) line is placed for sedation, and heart monitoring patches (electrodes) are attached to record the heart’s rhythm.
- Sedation:Â you stay awake throughout the procedure; a mild sedative is administered to help you stay relaxed. This may make you feel drowsy or slightly light-headed, depending on the sedation level.
- Insertion of the Catheter: A thin catheter is gently inserted into an artery through a tiny incision, typically located in the wrist or groin. The coronary arteries are reached by gently guiding this catheter through the blood channels.
- Injection of Dye: After the catheter reaches the coronary arteries, a contrast dye is released through it. This dye enhances the visibility of the blood vessels on the X-ray, enabling doctors to examine blood flow and identify any blockages..
- Treatment During the Procedure: If a blockage is detected, the doctor may perform angioplasty (using a balloon to widen the artery) or place a stent (a small mesh tube) to keep the artery open.
After the Procedure: Recovery and Care
Once the procedure is complete, you will be moved to a recovery area where the medical team will monitor your heart rate, blood pressure, and oxygen levels if the catheter is inserted through the groin, you might need to remain lying flat for several hours to minimize the risk of bleeding.
Some common post-procedure instructions include:
- To aid in your kidneys’ removal of the contrast dye, drink a lot of water.
- Refrain from intense physical activity and lifting heavy objects for a few days.
- Take rest for one or two days, especially if the catheter was inserted into your groin.
- Monitor for signs of complications like increased swelling, pain, or infection at the insertion site.
If you experience any chest pain, shortness of breath, or signs of infection, contact the doctor immediately.
Interpreting the Results
The results of a coronary angiogram can help doctors:
- Locate and evaluate the degree of blockages in the coronary arteries.
- Assess the volume of blood reaching the heart.
- Plan for possible treatments, such as angioplasty or stent placement
If no blockages are found, the test may help rule out coronary artery disease, leading to further investigation into the causes of any chest pain or heart-related symptoms.
