CT heart scan with a calcium score may be just as good as the results of a treadmill test to determine a future heart attack?

CT heart scan with a calcium score may be just as good as the results of a treadmill test to determine a future heart attack?

Calcium score of 0: A calcium score of 0 is predictive of no future heart attack because it means the individual doesn't have arteriosclerosis. Neither a stress test nor a CTA are crystal balls and neither accurately predict future heart attacks. Negative results mean the person is statistically at lower risk but if you are the among the 5 in a 100, your risk is 100%. We have no good test to predict the future. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

Echocardiogram, CT heart scan or cardiac mri. What does each one test for and how accurate are they? Holter results less than 1% of beats pacs an pvcs

Imaging tests: Echo uses sound waves to image cardiac structure and function. Ct scan uses computerized x-ray examination to do similar imaging and MRI uses yet another technology. Echo gives real time wall motion imaging while the other two are almost real time. They are all very accurate and each has its own strengths and weaknesses. We choose depending on what specifically we need in information. ...Read more

No symptoms. Healthy. Heart disease in family. Had CT heart scan to calc my calcium score of 83. Thoracic aorta ascending aorta was 3.8 cm, atherosclerosis . What does that mean? Age 50, 162lbs, BP 130/80, male, 6-1 height. No meds. Aspirin daily

Coronary calcium: Normal coronary arteries do not contain calcium. Therefore your mild to moderate score could indicate coronary artery blockage of uncertain degree. In view of your family history , I recommend that you undergo a maximal treadmill stress test (echo or nuclear)for further screening for significant coronary artery blockage and consideration for intensive statin therapy and Cardiology consultation. ...Read more

Is my high fat primal diet a good idea? I am off my statins, ratios and tris have improved. Tc still high, but CT heart scan shows calcium score 0.

Is my high fat primal diet a good idea?  I am off my statins, ratios and tris have improved.  Tc still high, but CT heart scan shows calcium score 0.

Probably: The devil is in the details. Both the details of your numbers and the details of your food choice. For example, if you are eating red meat, it is best to have grass-fed beef. So tough to answer in 400 words. That said, i would be very pleased with a calcium score of 0. Even with bad lipids a 0 score suggests very low risk for cardiac events. ...Read more

Can a heart scan CT calcium score show the presence of soft plaque in the arteries. If not, can an CT angiogram sans catheter do the job?

Can a heart scan CT calcium score show the presence of soft plaque in the arteries. If not, can an CT angiogram sans catheter do the job?

Yes: Soft plaque does contain calcium, so it will elevate the calcium score. CTA can estimate (key word: estimate) the degree of blockage. Researchers have tried to make predictive instruments that incorporate calcium scores. Check this one out sponsored by the NIH: http://www.mesa-nhlbi.org/Calcium/ArterialAge.aspx ...Read more

What heart scan is better, CT scanner or ultra scan?

What heart scan is better, CT scanner or ultra scan?

UltraSOUND: I think you mean cardiac ultrasound (also known as echocardiography). They look at different things. Echo sees over all function, wall thickness, chamber dimensions, valves, and can measure blood flow and pressure. Ct is for detecting calcium and looking at the coronary arteries. ...Read more

I had a lung and heart CT scan a week ago two weeks ago had a cardiogram and still nobody can explain why i still get chest pain can you help?

I had a lung and heart CT scan a week ago two weeks ago had a cardiogram and still nobody can explain why i still get chest pain can you help?

CP: I do not know the characteristics of your chest pain. A good history will point toward the diagnosis. Acid reflux inducing esophageal spasm and chest wall pain from heavy lifting its a possibility. Apparently they did a cardiac cath. And I am assuming its negative. Continue care with your doctors. Sometimes take time to match a symptom with a diagnosis. ...Read more

Why am i still experiencing fatigue 6 weeks after the flu very weak had heart CT scan and blood work all normal. Can't resume normal activity?

Cannot diagnose: This could be multiple different things. Whether you actually had influenza or an illness simulating it is the first of many questions that need answering. You are obviously seeing a doctor. Let them get to the root of this. If you are not satisfied, go see an infectious diseases expert. They are very good at working these things out. Good luck. ...Read more

What are the primary differences in a CT scan of heart and a nuclear stress test? Would one make more sense looking for blockages?

What are the primary differences in a CT scan of heart and a nuclear stress test? Would one make more sense looking for blockages?

CARDIAC IMAGING: A CT reveals anatomy with some limitation if heavy calcium is present & scanner technology dependent,A nuclear stress depends on the isotope (TCc vs Thallium vs one of the PET agents) reveals detailed information on function,often the 2 modalities are complementary and necessary for appropriate diagnosis and treatment/prognostication ...Read more
