What Is Coronary Angiography?

Coronary angiography is a procedure that uses X-rays to visualize and inspect arteries. It shows if there are any blocked arteries and how well your heart muscle is working.

During this procedure, a catheter is inserted into an artery in your arm or groin and advanced into one of your coronary arteries. Thereafter, contrast dye is injected into the coronary artery to make it visible on X-ray images.

The procedure can help identify blockages in the heart’s blood vessels and guide treatment decisions for patients at risk of developing heart disease or having a heart attack due to narrowed or blocked blood vessels that supply oxygenated blood to various organs.

When Is Coronary Angiography Performed?

Coronary angiography is typically performed if you have chest pain or other symptoms that suggest the presence of heart disease. If you have had a heart attack or have been diagnosed with coronary artery disease. It can be used in conjunction with an exercise stress test.

How Is Coronary Angiography Done?

If you’re scheduled for coronary angiography, here’s what you can expect:

  • The doctor will give you a sedative, usually in the form of an injection, at the start of your procedure.
  • They’ll insert a catheter into one of your arteries, either in your groin or wrist, and guide it through your blood vessels to reach your heart.
  • They’ll inject a special dye (contrast agent) into the coronary arteries that supply blood to your heart muscle so that they can see them clearly on X-rays taken after injecting this contrast agent.

Where Is Coronary Angiography Performed?

Coronary angiography is performed in a cath lab (catheterization laboratory). The cath lab is a room with special equipment for performing coronary angiography and other procedures that entail inserting a long, thin tube (called a catheter) into the blood vessels of your heart.

Why Is Coronary Angiography So Common Nowadays?

Advancements in medical science have made coronary angiography more accessible to patients. The procedure has become simple and the risk has reduced significantly. Also, unhealthy diets and lifestyle choices put more people at risk of developing cardiac ailments. That’s why coronary angiography is commonly performed now-a-days.

What are the risks involved in Coronary angiography?

In expert hands coronary angiography is a near-zero risk procedure. The risk of complications can be broadly categorized into:

Less severe complications

  • bleeding under the skin at the wound site (haematoma) – this should improve after a few days, but contact your Cardiologist if you’re concerned. Application of ice packs would be helpful.
  • bruising – it’s common to have a bruise in your groin or arm for a few weeks. Application of ice packs would be helpful.
  • allergy to the contrast dye used, causing symptoms such as a rash and a headache – this is uncommon, but you should discuss any allergies with your cardiologist before having the procedure

Severe complications

The chance for developing a serious complication during coronary angiogram is 1 in 1000. People with serious underlying heart problems are most at risk. Discuss with your cardiologist about the risks before the procedure.

  • damage to the artery in the arm or groin in which the catheter was inserted, with the blood supply to the limb possibly being affected 
  • heart attack – a serious medical emergency where the heart’s blood supply is suddenly blocked 
  • stroke – a serious medical condition that occurs when the blood supply to the brain is interrupted 
  • damage to the kidneys caused by the contrast dye 
  • tissue damage caused by X-ray radiation if the procedure is prolonged 
  • death

In Conclusion

Coronary angiography is used to diagnose and treat heart diseases, before cardiac surgery, angioplasty-stent procedures as well as other conditions such as aneurysms in blood vessels. It helps doctors identify underlying causes of heart failure and determine the proper course of treatment.

      Angiography is a minimally invasive procedure, which makes it extremely safe. However, it can involve a few minor side effects. The benefits outweigh the risks for most patients. However, in some cases, coronary angiography can result in serious complications.

      In this article, we’ll delve deeper into the risks and side effects associated with coronary angiography.

      Common Side Effects of Coronary Angiography

      If you’re planning to visit the doctor for an angiography, you can expect one or more of the following side effects:

      • Bruising
      • Swelling
      • A buildup of blood (resulting in a bump)

      All these symptoms are localized to the area where the cut was made for inserting the catheter. Most patients experience a gradual improvement in these side effects without medical intervention. You can take painkillers to relieve discomfort after the procedure.

      Complications of Coronary Angiography

      If you’re lucky, you’ll come out of coronary angiography with minor bruising and swelling. However, some patients develop the following complications:

      • An infection near the cut :- It makes the area around the cut red, swollen, and tender.
      • An allergic reaction to the dye :- It usually results in an itchy rash.

      In both cases, proper use of medications can help control the side effects. For instance, antibiotics can be used in the case of an infection. Similarly, your doctor might prescribe antihistamines if you experience an allergic reaction.

      It’s worth mentioning that coronary angiography comes with a few potential serious complications. These include:

      • Kidney damage (from the dye)
      • Cardiac arrest or stroke
      • Internal bleeding (due to damaged blood vessels)
      • Anaphylaxis (due to severe allergic response to the dye)

      The good news is that these complications are extremely rare (affecting less than one in every 1000 patients). Also, kidney damage due to angiography is usually temporary. Moreover, internal bleeding can be contained with the help of catheter based approaches.

      Seeking Medical Help

      Complications from coronary angiography are rare. Nevertheless, it’s a good idea to consult your doctor if you notice anything unusual after the procedure. For instance, if the leg or arm where the cut was made looks pale or feels numb, it’s a cause for concern. Similarly, if you notice bleeding, redness, or a firm lump near the cut, it could indicate a potential infection. It’s always a good idea to watch out for these signs and consult your doctor for timely treatment.

      In Conclusion

      Coronary angiography is a safe and minimally invasive procedure. It can cause minor side effects, such as pain and swelling. However, in extreme cases, it can also lead to a heart attack or kidney damage. It’s crucial to talk to your doctor about the potential risks before going in for the procedure.

          Heart failure is a serious condition that can result in organ damage and death (if left untreated). If you want more information about the different types and symptoms of heart failure, take a look at our previous blog posts.

          In this article, we’ll explore the different causes of heart failure in greater detail. Let’s get started.

          Heart Failure: A Closer Look

          Heart failure refers to a condition where the heart is unable to pump blood throughout the body with maximum efficiency. It’s usually the result of progressive weakening, thickening, or stiffening of the heart muscles.

          In the past, doctors used to refer to the condition as congestive cardiac failure because it leads to fluid buildup and congestion in the lungs. However, recent research shows that heart failure can cause several other symptoms.

          Symptoms of Heart Failure

          It’s possible for patients to develop heart failure without showing symptoms for months. That’s because they might attribute signs like confusion and fatigue to other factors, such as old age and stress.

          However, if you’re at risk of developing heart failure, you should watch out for the following symptoms:

          • Swelling in the abdomen, feet, and legs
          • Shortness of breath that worsens due to physical exertion or when lying down
          • Weight gain due to fluid buildup
          • Loss of appetite
          • Pale or bluish skin

          Causes of Heart Failure

          Heart failure can be the result of various underlying conditions, including hypertension, diabetes, chronic respiratory disease, cardiomyopathy, and coronary artery disease. Also, it can be caused by damage to the heart muscles due to a viral or bacterial infection or a previous heart attack.

          Moreover, faulty heart valves can strain the cardiac muscles and lead to heart failure. Similarly, heart rhythm disturbances can create structural changes in the left ventricle and cause heart failure.

          It’s worth noting that people with a family history of cardiac ailments are more prone to developing heart failure. Also, the risk is higher in seniors and people with an African-American ethnic background. Alcohol consumption, tobacco smoking, and substance abuse also increase the risk.

          Types of Heart Failure

          Depending on the phase of the heart’s pumping cycle that’s affected by congestive cardiac failure, the condition can be of two types:

          • Systolic heart failure – Heart failure due to a problem in the contraction (systolic) phase of the pumping cycle; also known as heart failure with reduced ejection fraction.
          • Diastolic heart failure – Heart failure due to a problem in the relaxed (diastolic) phase of the pumping cycle; also known as heart failure with preserved ejection fraction.

          Heart failure can also be categorized as:

          • Left-sided heart failure (caused by a weak left ventricle)
          • Right-sided heart failure (caused by a weak right ventricle)

          Stages of Heart Failure

          The American Heart Association (AHA) and the American College of Cardiology (ACC) have identified four distinct stages of heart failure based on the degree of severity. The course of treatment for a patient depends on the stage of heart failure they’re at.

          Diagnosing Heart Failure

          Heart failure is diagnosed through a series of lab tests, including ECG, echocardiogram, coronary angiography, chest X-ray, brain natriuretic peptide test, etc. Doctors recommend the right combination of tests to identify the causes of heart failure and devise a suitable treatment plan.
