An angiogram is one of the most important diagnostic procedures used to evaluate the condition of blood vessels, especially those supplying the heart. By using a special contrast dye and X-ray imaging technology, doctors can clearly identify narrowed arteries, blockages, or other abnormalities that may affect blood flow.

When performed to examine the arteries of the heart, the test is called a coronary angiogram. It plays a vital role in diagnosing chest pain, suspected heart attacks, shortness of breath, and coronary artery disease. The results help cardiologists determine the most appropriate treatment, such as medication, angioplasty with stent placement, or coronary artery bypass surgery.

What Is an Angiogram?

An angiogram is a medical imaging procedure that allows doctors to visualize the inside of blood vessels. During the procedure, a special iodine-based contrast dye is injected into the arteries, and X-ray fluoroscopy is used to monitor blood flow in real time.

This test helps identify:

• Whether an artery is blocked

• The location and severity of the blockage

• Narrowing or damage to blood vessels

• Whether blood is flowing normally

Why Is an Angiogram Performed?

A cardiologist may recommend an angiogram for several reasons, including:

• Evaluating the cause of chest pain

• Assessing the risk of a heart attack

• Detecting coronary artery blockages

• Identifying narrowed or damaged blood vessels

• Planning treatment with medication, stents, or bypass surgery

An angiogram provides detailed information that helps doctors make accurate diagnoses and treatment decisions.

How Is an Angiogram Performed?

1. Preparation Before the Procedure

Patients are usually asked to fast for several hours before the procedure. Blood tests, kidney function tests, and other necessary evaluations may be performed beforehand. The healthcare team also obtains informed consent.

2. Transfer to the Catheterization Laboratory

The patient is taken to a cardiac catheterization laboratory (Cath Lab), where heart rate, blood pressure, and oxygen saturation are continuously monitored.

3. Local Anesthesia

A local anesthetic is administered to numb a small area, usually at the wrist (radial artery) or the groin (femoral artery), to minimize discomfort.

4. Catheter Insertion

A small sheath is inserted into the artery, followed by a thin, flexible catheter that is carefully guided toward the coronary arteries.

5. Contrast Dye Injection

A contrast dye is injected through the catheter, making the arteries visible on X-ray images as the dye flows through the blood vessels.

6. Image Evaluation

Real-time images allow the cardiologist to determine:

• The presence of arterial blockages

• The percentage of narrowing

• Which arteries are affected

• The most suitable treatment approach

7. Completion of the Procedure

Once imaging is complete, the catheter is removed. If the radial approach is used, a pressure band is applied to the wrist. If the femoral approach is used, the patient may need to remain lying flat for several hours.

How Long Does an Angiogram Take?

A routine coronary angiogram typically takes 10 to 20 minutes. However, the duration may vary depending on the patient's condition and the complexity of the procedure.

Approximate Cost of an Angiogram in Bangladesh

The cost of an angiogram varies depending on the hospital, available facilities, and medical services provided.

Government Hospitals

• Approximately BDT 2,000–5,000

• Costs are generally lower due to government subsidies, although waiting times may be longer.

Private Hospitals

• Typically BDT 15,000–30,000 or more

• Prices vary depending on the hospital, cardiologist, and service package.

Factors That Affect the Cost

• Hospital facilities and reputation

• Quality of the catheterization laboratory

• Cardiologist's consultation and procedure fees

• Radial or femoral access technique

• Whether medications, reports, and observation are included in the package

For the most accurate and up-to-date pricing, patients should contact the hospital's cardiology department directly.

Aftercare Following an Angiogram

Proper care after the procedure helps ensure a smooth recovery.

• Do not remove the pressure band unless instructed by your healthcare provider.

• Avoid heavy lifting or strenuous activities for at least 24–48 hours.

• Drink plenty of water to help eliminate the contrast dye from your body.

• Contact your doctor immediately if you experience excessive pain, swelling, bleeding, numbness, or redness at the insertion site.

• Take prescribed medications as directed and attend all follow-up appointments.

Is an Angiogram Safe?

An angiogram is considered a safe and commonly performed diagnostic procedure. With modern catheterization laboratories and experienced cardiologists, the risk of serious complications is very low. Although minor risks exist, most patients undergo the procedure without significant problems.

Conclusion

An angiogram is a reliable and highly effective diagnostic procedure for evaluating the health of the heart and blood vessels. It helps identify arterial blockages, narrowing, and blood flow abnormalities, allowing doctors to recommend the most appropriate treatment, whether medication, angioplasty, or bypass surgery. Early diagnosis through angiography can reduce the risk of serious heart complications and significantly improve long-term health outcomes.
