Normal stress test, Echo and cardiac CTA - can I be 100% certain nothing is wrong with my heart?

1 doctor agreed:
Normal stress test, Echo and cardiac CTA - can I be 100% certain nothing is wrong with my heart?

Yes and No: You can be extremely sure (nothing in science is 100%) that your coronary arteries are clean and your heart is functioning normally. MACE (major adverse cardiac events) in patients with normal CTA are nonexistent for 2 years. Having said all that, there are cardiac diseases that would not show up on the tests you have had. Cardiac amyloidosis and sarcoidosis, myocarditis, ARVD and conduction ...Read more

Is nuclear stress test or Cardiac CTA better for ruling out clogged arteries? My nuclear test was clear but they couldn't do CTA due to heart rate.

Is nuclear stress test or Cardiac CTA better for ruling out clogged arteries? My nuclear test was clear but they couldn't do CTA due to heart rate.

Nuclear stress test: The nuclear stress test is better because (1) it is a functional test - your heart is actually "stressed" to beat harder, & (2) you can do it at any heart rate (as you've seen). The cardiac CTA only tells you anatomy - whether or not there is calcium in the arteries - not how your heart functions. Not all plaques contain calcium, either, so cardiac CTA has false negatives also. Talk to your doctor ...Read more

Can a cardiac MRI be done at any heart rate or will my fast rate be a problem like with the CTA?

Can a cardiac MRI be done at any heart rate or will my fast rate be a problem like with the CTA?

Tachycardia: Hi GirishZ, it depends on how fast your HR is. Considering your age (26), I would be curious why a cardiac MRI is needed. And if so, you likely are under close follow up with a doctor. If you have a rapid HR, it would best for you in general, to get it below 110. See your doctor if it is consistently higher than that or if you are having symptoms. Hope that's helpful. ...Read more

3 years ago I had a carotid CTA which detected an intermittent cardiac arrhythmia. I am experiencing heart rate spikes. Was that arrhythmia real?

3 years ago I had a carotid CTA which detected an intermittent cardiac arrhythmia. I am experiencing heart rate spikes. Was that arrhythmia real?

Review of records: In general, the results of tests that you had done should be available to you, and you can take them to another doctor for review. Don't assume that the 2nd opinion doctor will have access to the tests unless you bring them. It is valuable to get not only the written report on paper but also for some tests the images themselves, usually on a CD. Only by seeing the data can a 2d opinion doctor help ...Read more

When measuring ascending aorta size (horiz)from sinotobular junction to innominate artery is cardiac mri/mra for morphology more accurate test than cta?

When measuring ascending aorta size (horiz)from sinotobular junction to innominate artery is cardiac mri/mra for morphology more accurate test than cta?

Depends: Done properly, ideally with ECG gating, an aortic MRA is equivalent to an aortic CTA. The opinion from some vascular docs is an overestimation on MRA. This was probably from movement artifact and older scanners. The benefit of MRA is the lack of iodinated contrast and lack of radiation. It is in routine use at many large medical facilities to periodically track aortic enlargement- kids/adults ...Read more

Intermittent cardiac arrhythmia found during carotid cta 3 yrs ago. Experiencing seizures w/heart rate spikes could arrhythmia contribute to this?

Seizures can cause: An increase in heart rate however not the other way around. Defining the nature of the heart rate response is important. You need to see a health care provider and have them obtain the appropriate testing. ...Read more

Will a coronary CTA with Calcium score show if I have PAD?

Will a coronary CTA with Calcium score show if I have PAD?

CAD often = PAD: Calcium score of the coronary arteries indicates some degree of atherosclerosis or hardening of the arteries. The CTA does not specifically look at the rest of the body i.e. legs, neck, etc. However atherosclerosis is usually a systemic disease such that if there is CAD there is likely some degree of peripheral arterial disease (PAD) also. ...Read more

How accurate is a CTA coronary angiogram? Done at the mayo clinic... Accurate as in seeing hard and soft plaque....????

Extremely accurate: Mayo is among the finest hospitals in the world, and a properly done Coronary CTA can see all manner of arterial narrowing, whether soft or hard plaque. Because of the contrast given, the artery diameter can be measured along each vessel. Discuss the results with your doctor. You may have other reasons for your symptoms other than CAD, especially if you are only 27. ...Read more

Cardiology: Is the so-called warm flush feeling one gets from a coronary CTA exam the same feeling as the fast HR of a nuclear stress test, or not?

Cardiology: Is the so-called warm flush feeling one gets from a coronary CTA exam the same feeling as the fast HR of a nuclear stress test, or not?

Same & different: The warm flush of a nuclear stress if from regadenoson or adenosine. A coronary CTA uses iodinated x-ray contrast agent - completely different. However, the feeling may feel similar. A flush is a flush. Niacin can do this too. So can being embarrassed. ...Read more

Nuclear stress test and cardiac coronary CT angiogram, which do you recommend?

Nuclear stress test and cardiac coronary CT angiogram, which do you recommend?

Depends on situation: Nuclear stress test involves looking at perfusion of heart for defective areas representing coronary artery disease looking for areas of permanent damage versus areas that are reversible possible related to area of coronary narrowing. Coronary ct angiogram looks at anatomy of coronary arteries looking for areas of narrowing and blockage. Answer depends on information physician needs and insurance. ...Read more

I had a coronary cta and calcium score that was normal 6 months ago. I do have Wolff-Parkinson-White syndrome but does the cta prove no heart attack?

CTA and heart attack: A cta does not prove one has had a heart attack (mi). It onlyshows the anatomy of the coronary arteries. If they are diseased, you are more prone to developing a mi. Ekg's can show the presence of an acute mi or an old one.
At age 18, you are a bit you to have a cta. What was your physician (p) thinking when the p ordered the study? ...Read more

Is a coronary calcium ct scan a good test to see of there is plaque in the heart arteries? How accurate is it? My cta was inconclusive. Heart rate fas

Coronary Calcium: Coronary Calcium analysis is a method to detect calcified cholesterol in the coronary arteries. A score of zero is quite helpful and predictive in the correct age group. The difficulty is that in younger people, there may be noncalcified cholesterol plaques in the arteries which would not be detected on a coronary calcium screening test, so cardiac CTA or invasive angiography would be considered. ...Read more

I'm 21 and have had problems with angina-like pain all mylife. More recently, I have started getting palpitations and breathlessness. I have had ekgs, holter, echos, bloods and cardiac CT angiogram done. Have I left any bases uncovered?

Look elsewhere: You seem hung up on cardiac causes but you haven't said anything about consultation with a gastroenterologist to look at your esophagus. Esophageal spasm can mimic angina and can even get better with nitroglycerin. You should also consider whether or not this is an anxiety or panic attack. ...Read more

What's safer: coronary angiogram or CT angiogram?

What's safer: coronary angiogram or CT angiogram?

Ct vs cath: In simplest terms the ct angiogram would be safer than a coronary angiogram, however, they are usually used in different circumstances. The ct angiogram is useful as a screening tool to see if coronary disease is present. A cardiac catheterization is performed when a patient has an acute coronary syndrome or a myocardial infarction to evaluate coronary disease, or even treated. ...Read more

Coronary CT angiogram shows extremely high calcium score of 4242 and ~ 70% blockage one artery. Next step cath angio. Should I consider atherectomy?

NO: You need a coronary angiogram-depending what it shows, you may need revascularization. Depending on location and extent, you may need surgery. Otherwise, balloon angioplasty followed by stenting is the treatment of choice. Atherectomy has a very limited and specific indication. If you need it, your interventionalist is the one to make the call. ...Read more

If a coronary ct angiogram Done at mayo clinic in Arizona says I have 0 plaque is it very accurate? My heart rate was 50, how good is that test? Help.

If a coronary ct angiogram Done at mayo clinic in Arizona says I have 0 plaque is it very accurate? My heart rate was 50, how good is that test? Help.

Accurate: CT angio is accurate and your heart rate of 50 was really in the ideal range for the test. If you still have concerns may want to have a stress test that will show changes related to your heart related to higher work loads than at rest. Unless you have some familial lipid/cholesterol problems you are still fairly young to show plaques, though if you smoke you will accelerate their appearance. ...Read more

Will a CT angiogram of the coronary arteries reveal a pulmonary embolism or other lung disease and is it harmful to have 2 CT scans in the same month?

It might: A CT angiogram or the coronaries might show a pulmonary embolism, provided that the radiologists obtained full field of view reconstructions (some do not) and the pulmonary embolism is not higher or lower than the field of view. Most often, the answer would be yes, a significant PE would be identified on this type of scan. Having two ct's in the same month is not optimal, but likely of no harm. ...Read more
