Care-After-Coronary-Angiography.jpg

Many people have heart disease, but not all of them know it. Doctors use a variety of tests to identify cardiac ailments and their underlying causes. Coronary angiography is one of the most common diagnostic tests that doctors use.

While it’s considered a safe and minimally invasive procedure, coronary angiography comes with a few risks. You can read more about the potential risks and complications in our previous blog.

The good news is that you can avoid side effects with proper care after the procedure. If you’ve recently had coronary angiography or are going through one soon, here is what you need to do after the procedure:

Avoid Heavy Physical Activity

It’s important to rest after coronary angiography. Avoid lifting heavy objects or resuming your exercise routine right after the procedure. Make sure you get plenty of sleep and let your body and mind relax for at least a week after angiography. Ask your doctor if you’re unsure when to hit the gym or start exercising.

Embrace Healthy Habits

Avoid cigarettes for at least a few days if you are a smoker. Smoking can cause spasms in the coronary arteries, leading to a heart attack or stroke after your angiography. Also, avoid alcohol consumption, and make sure you eat a balanced diet.

If you are a coffee drinker or have high blood pressure, avoiding all caffeine products (coffee, tea) and salt for several days following your procedure may be a good idea. The most important thing is to listen carefully to what your doctor tells you about caring after coronary angiography to avoid any other complications during recovery or later down the road.

Be Careful About Removing the Bandage

A crucial step to caring after coronary angiography is to avoid removing the bandage until the morning of the second day after the procedure. Also, you should not remove it yourself. Let someone else help you remove it. You must consult your doctor or nurse before removing the bandage.

Expect Soreness and Pain for a Few Days

Your arm or leg (where the catheter was inserted) might feel sore for a few days following a coronary angiogram. The discomfort you feel is usually caused by the catheter or dye used for the test. 

The catheter may have been left in place too long, leading to irritation and inflammation. Or it could be a reaction to the dye that was used to take images of your arteries during the procedure. It can also happen if you’re allergic to any component of either one.

In most cases, the pain and soreness should subside after a few days. If the pain persists or the arm/leg becomes numb, it’s a good idea to reach out to your doctor. Also, if you have a fever or trouble breathing, call your doctor right away. 

If you are bleeding from the incision site, apply direct pressure with a gauze dressing until the bleeding stops. Don’t remove the dressing unless instructed by medical staff at the hospital.

Conclusion

Coronary angiography is a safe and effective procedure that can give you a better understanding of your heart health. If you follow your doctor’s instructions, you’ll be on the road to recovery in no time.

      Doctors use various diagnostic tests to assess cardiac health and diagnose conditions like coronary artery disease and heart failure. While a coronary angiogram is commonly used to identify these conditions, your doctor can prescribe other tests like CT coronary angiography. 

      In our previous blogs, you can read more about the use cases and risks of coronary angiography. In this article, we’ll delve deeper into CT coronary angiography and understand why it’s crucial for people with cardiac ailments.

      What Is CT Coronary Angiography?

      CT coronary angiography is a type of CT scan that uses special dyes to evaluate the heart’s blood vessels. It can detect blockages in the coronary arteries that supply blood to the heart. It can identify blockages that are too small for other methods, such as a regular angiogram or an electrocardiogram (ECG), to pick up.

      CT coronary angiography

      A CT coronary angiography scan aims to find any abnormal areas in your coronary arteries that could be causing stenosis (narrowing) or occlusion (blockage). It helps doctors identify underlying heart-related ailments and determine the right course of treatment.

      How Does CT Coronary Angiography Work?

      The test is usually done in a hospital or clinic. To begin with, the doctor or radiologist will start an intravenous (IV) line to administer the contrast dye. As the contrast flows through your veins, it will appear on the scan as bright white areas on a black background. It’ll help the doctor see your heart and coronary arteries. 

      The test usually lasts about 30 minutes to one hour. The CT coronary angiogram procedure involves two scans: one with diastolic blood flow and another with systolic blood flow

      When Is CT Coronary Angiography Used?

      CT coronary angiography is used to diagnose a heart attack and evaluate blood flow in the heart. Also, doctors use it to detect blockages in arteries that supply blood to the heart muscle.

      What Are the Risks of CT Coronary Angiography?

      While CT coronary angiography is a non-invasive and safe procedure, it can cause the following side effects:

      • You may have an allergic reaction to the contrast dye.
      • Your body will be exposed to high levels of radiation, which can increase your risk of developing cancer.
      • You might have to pay out of pocket because the test isn’t always covered by insurance.
      • You might experience more anxiety and stress if the scans indicate blockages in your arteries.

      What Should I Expect When Having CT Coronary Angiography?

      If you are planning to get a CT coronary angiography, you should be prepared for the following:

      • The radiologist will ask you to change into a hospital gown.
      • The radiologist will give you an injection of a contrast dye.
      • You will lie on a table, and the table will move into the CT scanner.
      • The scan is painless and takes about 20 minutes.

      Conclusion

      CT coronary angiography is a painless and safe test that can help determine if you have blocked arteries. If you have chest pain, you should consider getting the test done as soon as possible because it may save your life.

          Coronary angiography is a common diagnostic test used by doctors to identify conditions, such as coronary artery disease and aneurysms. In our previous blog, we discussed how the procedure is carried out and when it’s used. Click here to check it out.

          coronary angiography

          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.

              Coronary-Bifurcation-Lesions.jpg

              Coronary arteries are the vessels which supply blood (oxygen and nutrients) to the heart; this supply may be disrupted due to buildup of cholesterol and fatty deposits, called plaques, on the inner walls of the arteries (atherosclerosis) causing narrowing of the vessel lumen.

              Coronary lesions branch out as they progress to supply various cardiac structures. A bifurcation lesion is a stenosis or abnormal narrowing of greater than 50% that occurs in a coronary artery at the origin of the side branch or adjacent to the origin of the side branch. Branching points a.k.a bifurcation points in the coronary arteries are prone to develop atherosclerosis as the shear stress is higher at the branch points.

              The figure shows how a bifurcation stenosis appears schematically as well as on angiography.

              bifurcation lesion

               

              Why bifurcation lesions are important?

              A vast majority of coronary arteries obstructions happen at the branching point. About 15-20% of patients of referrals for bypass surgery are because of the presence of coronary narrowing at bifurcation location. They are considered a tough lesion to treat by angioplasty and stent.

              How are bifurcation lesions diagnosed?

              Bifurcation lesions are identified on coronary angiography. Only lesions affecting side branch blood vessels more than 2.25 mm is considered important and called bifurcation lesions. The main vessel that gives branches is called main vessel and the branches that originate from it are called side branches. The point at the division of the main vessel and side branch is called a bifurcation point.

              How is a bifurcation lesion unique?

              Bifurcation lesions can involve the coronary artery either before or after the bifurcation point. In addition, side branches could be either diseased or free from disease. Based on the location and severity of the cholesterol plaque at the bifurcation point, sub types of bifurcation lesions have been identified.

              The challenge of performing angioplasty and stent for a bifurcation stenosis lies in the ability to preserve the main vessel and the side branch. Stents being metallic tubes risk occluding the side branch when placed across the side branch. This apprehension of losing the side branch, is one of the primary reasons for patients to be sent for bypass surgery instead of angioplasty and stent.

              Coronary-bifurication

              Can angioplasty and stent be performed for a bifurcation lesion?

              Angioplasty and stent can be eminently performed for a bifurcation stenosis. Over the last 2 decades numerous techniques in stent implantation have been developed to treat the bifurcation lesions. Some of these techniques include:

              • Provisional T stent technique
              • Tap technique
              • Double kiss crush technique
              • Culotte technique

              Advent of these techniques enabled experienced operators to perform angioplasty and stent successfully with chances of repeat narrowing seen in 3-6% patients at the site of stenting. Risk of losing a side branch after stenting is reduced to 1% once the new techniques are employed.

              Dr. C Raghu is an expert in bifurcation lesion angioplasty and the center where he has been trained, ICPS Paris France is considered the “Mecca” for bifurcation lesion angioplasty techniques development. 

              How does a bifurcation lesion angioplasty differ from a normal angioplasty?

              Bifurcation lesion angioplasty, involves utilization of novel stent techniques mentioned above. In addition, angioplasty operator experience is a major factor in determining  outcomes. Choosing the “right” stent that allows side branch access, use of specialized technologies such as fractional flow reserve (FFR), expertise in deploying 2 stents especially the process of “stent crush” and the handling of two balloons through a single catheter – kissing balloon are key points for the best results in a stent procedure.

              What are the chances of side branch occlusion in a bifurcation lesion angioplasty?

              Contemporary bifurcation angioplasty using Intravascular imaging employing contemporary stenting techniques in the hands of expert bifurcation angioplasty operators carries a 99% success rate with a chance of losing side branch in 1% and repeat narrowing at the end of 9 months being 3-6%. These results are comparable and if not superior to bypass surgery as angioplasty entails a short hospital stay and fast recovery.
