The last one we had, instead of doing angiograms, they are now doing CT scans instead. It is more comfortable than the old angio's, but wonder if they are as good as the angiograms or not. At least with the angiogram if you need a stent it can all be done at once instead of a CT scan, & then another procedure to place the stent. I have three already, & a pace maker because they lost me on the table. Could this be the reason or is it just safer? Just wondering if anyone else is having this done.
A number of imaging tests may be used to see how well blood moves through your arteries.
Doppler tests use ultrasound or sound waves.
Magnetic resonance arteriography (MRA) is a special type of MRI scan
Special CT scans called CT angiography
Arteriograms or angiography use x-rays to see inside the arteries
Coronary CT angiograms are becoming a common option for people with a variety of heart conditions.
Unlike a traditional coronary angiogram, CT angiograms don't use a catheter threaded through your blood vessels to your heart. Instead, a coronary CT angiogram relies on a powerful X-ray machine to produce images of your heart and heart vessels. CT angiograms don't require the recovery time needed with traditional angiograms.
CT angiograms will expose you to a small amount of radiation.
For you specifically since you have known coronary artery disease, a traditional coronary angiogram may be a better option, since you can also receive treatment for your artery blockages during a traditional coronary angiogram.
Talk to your specialist about which test is best for you.
Hello Gary and a warm welcome to DC
The movement in health care is to make procedures less invasive, quicker and cheaper. Also many countries have screening programmes (UK spelling) for many different conditions; with the aim to diagnose and treat any abnormalities in its early stage. The reason why you had a Cardiac CT (That it what you had, but which one?) is because it’s the future. This is the way that heart function and disease will now be assessed and screened. Angiogram/ Angiography will become the gold standard, as it is more accurate in its ‘observations’ and treatment like stenting can be undertaken. However it will we used following Cardiac CT (CCT) for the reasons aforementioned. As advances in CCT technology continues to develop (and it is at a quick pace) Angiograms will diminish. It is worth noting that CCT is a CT scan machine and will be also used for scanning other areas of the body. The difference is that these newer CT scan machine take much more detailed images and so now can be used to scan the heart. There are two types of procedures undertaken with CCT
1) Coronary Calcium Screening
2) Detection of Coronary Artery Disease (CAD).
Coronary Calcium Screening (CCS) takes place in a CT machine but this machine doesn't show the beginning of blockages in the Coronary Arteries (CA). It detects if there is any calcium deposits in the CA as this is an indication that the beginning of a potential blockages to the walls of the CA is forming. This is called Artherosclerosis. By CCS the patients can be treated way before they would develop symptoms of coronary disease. The advantage of this procedure is that no contrast is required to see the CA. Low radiation exposure- No recovery time – non invasive and it is the cheaper of the two types of procedures. Disadvantage is that it may not be correct. In a small scale study Artherosclerosis was found in a number of patients via Angiogram who had been told that no calcium deposits had been detected using CCS.
Which Patients will receive this investigation? = Those who are part of a countries screening programme -Those who marginally have elevated: cholesterol and high blood pressure, smoking history – Diabetes -Family history of heart disease - Asymptomatic (have no symptoms) CAD patients, classed as having an intermediate risk of developing CAD but with lifestyle changes and pharmacologic therapy the risk would be reduced - CCS may be reasonable in some symptomatic patients -To assess patients who have equivocal treadmill or functional test results -To assess patients with chest pain who have equivocal or normal echocardiography findings and negative cardiac enzyme test results.
Detection of Coronary Artery Disease (CAD). This CCT does detect blocked, partial blockages and the beginning of blockages of the CA. In other words this CCT detects CAD. This type of CCT is used to assess heart chambers, heart valves and the surrounding blood vessels, however for now it is mainly used to rule in or out blockages. If a blockage of any type is detected an Angiogram is undertaken. The advantages are it is less invasive and quicker than an Angiogram. Quicker recovery time. Disadvantages are with the make and model of the CT machines. Some machines require the patient to have a contrast medium. Some machines require the patient to have a drug to slow their heart rate down. The images produced can be in 2 dimensional, 3 dimensional of high definition - High radiation exposure – In accurate data for e.g. image may say that you have a 60% blockage but the Angiogram shows that it higher or lower than this.
Which Patients will receive this investigation? = Those who are part of a countries screening programme - Symptomatic CAD patients
