Common Questions and Answers about Stress test heart muscle

Avatar m tn Stunned heart muscle does not recover as rapidly as hibernating heart muscle. But in contrast with infarcted heart muscle, in which many muscle cells are dead, it does indeed recover. Function in the stunned heart muscle may not return for 10 to 16 days after the restoration of blood flow. To answer your question of how long depends on whether the heart cells are stunned, hibernating or necrotic...or combination of the 3 variables.
Avatar m tn Each test is progressivly more accurate. An EKG is about 50% accurate, a normal stress test is about 65% accurate and a nuclear stress test is about 85% accurate overall but if you back out the false positives, it will find significant heart disease 97% of the time. Having said that, are you working with your doctor to find a cause other than heart disease?
Avatar n tn My nuclear stress test results were as follows ver batim. I do not know what it means, are the results acceptable, good very good etc. What does this say about the blood flow to the heart muscle ? "injection of Myoview nuclear tracer & resting images obtained excercised on a treadmill for 5 min 34 sec. to 10.
512736 tn?1211343352 4-16-08 at cardiologist office and had an angina attack and was told I need a stress test. I have had these tests before and it will be fine and 2 weeks later I am being rushed to emergency for stents. Why did this not show on stress test? They are expensive. Thank You for your help!
Avatar f tn My husband is 66 and recently had a SPECT Myocardial Perfusion Imaging Study (stress test). It was essentially normal, with the exception of the following: "there is a moderate sized reversible defect of the inferior and apical walls". The left ventricle was normal in size and the ejection fractions were 57% at rest and 63% post stress. The internet resources suggest that such a defect could be indicative of a prior silent heart attack. Is this true?
Avatar f tn An echo looks at the structure and function of the heart, whereas the stress test was looking for blockages causing your symptoms. Having a leaky valve can predispose to certain abnormal heart rhythms which may have caused your palpitations, weak heart muscle (AKA heart failure) can cause leg swelling and shortness of breath -- neither of these things are detectable with a treadmill stress test unless there was an echo done at the same time.
Avatar f tn This is when a blood vessel completely blocks, preventing oxygen getting to the part of the heart muscle concerned. The area of muscle which has been killed is small, but it has resulted in abnormal wall movement. However, the overall function of the left ventricle is good and your heart is pumping well, giving an EF of 56% which is fine. You was very lucky that the blockage was probably low down in the Coronary artery, causing only a small attack.
Avatar f tn When using EKG and blood pressure monitoring alone the test is variously called a cardiac stress test, exercise stress test, exercise treadmill test, exercise tolerance test, stress test or exercise ECG test. Heart rate, breathing, blood pressure, EKG, and how tired you feel are monitored during the test.
Avatar m tn Reversible means the blockages are not total, and no heart muscle is damaged, so intervention with stents or bypass will make things much improved. If the blockages are not severe enough, they may try to help with medication. I think you will be required for an Angiogram next to see the exact extent of the disease.
Avatar m tn The risk during a nuclear stress test is extremely small for a heart attack, etc. or any adverse effect. To ensure your full safety, this test will be performed in laboratories that are fully equipped and very carefully and professionally monitor of the patients during the test and this will assure the detection and treat any abnormal conditions that may develop during the course of testing.
Avatar n tn If a stress thallium test shows scar tissues does it mean, the scar is across complete thickness of that particular heart muscle section. Could it be possible that the scared muscle tisssues on the surface, which is imaged, may actually have healthy tissues below them. It is said that blood is locally distributed to heart muscles by smaller size arteries.
Avatar f tn test with myocardial perfusion imaging revealed mild to moderate ischemia involving the basal anterior septum and mid anterior septal walls. He is status post recent (4/7/08) four-vessel bypass graft with a LIMA to the LAD. My husband has been labeled a walking piece of plaque by his cardiologist. With his open-heart surgery being so recent, with him being diabetic, and he has never had any symptoms of his illness - should this recent test be looked into further by your opinion?
Avatar f tn Was the stress test completed, or stopped due to shortness of breath, muscle fatigue, irregular EKG findings, etc.

Avatar m tn I had an abnormal stress test last week, and I had a heart attack many years ago. My cardiologist said he thinks I should have a Heart Cath, but is leaving it up to me. He said something that was confusing to my husband and me. He said my heart performed good during the stress test but that was bad. Sounded contradictory to us.
Avatar f tn I recently had an abnormal EKG that showed a LBBB. I was sent for a Lexiscan stress test and this was the conclusion: Calculated post stress LVEF 51%. There was a medium sized mild to moderate, fixed defect in the basal anteroseptal, mid anteroseptal, apical anterior, apical septal, apex segments.
Avatar f tn A Thallium Stress test looks at the blood flow to your heart muscle at rest and during stress. During a stress test, a radioactive material called Thallium is injected into a vein. A gamma camera takes pictures of the Thallium in your heart. the EKG and Echo were at rest and they are Fine ! now A Thallium Stress test just to see how your heart Managing the blood during stress.
1491262 tn?1288413065 The test appropriate for evaluation of pumping ability would be to analyze the degree of heart wall movement impairment from thd prior heart attack. Apparently, the stress stress was a perfusion test to view the blood flow at rest and during exercise. With exercise there is a higher demand for blood/oxygen and the test results would help determine the degree of blockage, etc.
Avatar m tn There are probably some minor variations in your ECG that a thallium test ( looks at blood flow through out the heart muscle) would explain. Probably nothing.
Avatar n tn I can produce a numbert of different opinions what is the appropriate heart rate and so on with exercising. The best method for someone with a heart issue is to have a stress test. A stress test is oftened done for the purpose of learning the degree of tolerance/risk one can safely do. The rule of thumb stated is not recommended for someone who has heart issues. You will be safe to engage in exercising according to METs.
Avatar m tn thallium stress test Report.. Please Tell me the conclusion of Report ? do I need angiography ? Dipyridamole myoview spect myocardial perfusion study Age / Sex : 65/M Indication: HTN, DM, ? IHD Isotope : 7mCi of Tc-99m Myoview at peak stress 21mCi of Tc-99m Myoview at rest Persantin Infusion Stress: Pharmacological Intervention was performed with injection persantin (Dipyridamole) at a rate of 0.142 mg/kg/min, 07 Mci of Tc-99m Myoview was given I/V. His resting ECG showed 0.
Avatar n tn A nuclear stress test lets doctors see pictures of your heart while you are resting and shortly after you have exercised. The test can give information about the size of the heart's chambers, how well the heart is pumping blood, and whether the heart has any damaged or dead muscle. Nuclear stress tests can also give doctors information about your arteries and whether they might be narrowed or blocked because of coronary artery disease.
