Coughing After Cardiac Stress Test
Extremely lightheaded after Cardiac stress test, but it came back completely normal. Report showed no abnormalities. Is the lightheadedness okay?
Depends: It all depends on how long you ran for on the treadmill. If there were no arrhythmias noticed. It most likely was just related to strenuous exercise. But if it persists I would seek medical attention. ...Read more
Stress affects most people in some way. Acute (sudden, short-term) stress leads to rapid changes throughout the body. Almost all body systems (the heart and blood vessels, immune system, lungs, digestive system, sensory organs, and brain) gear up to meet perceived danger. These stress responses could prove beneficial in a critical, life-or-death situation. Over time, however, repeated stressful situations put a strain on the body that may contribute to physical and psychological problems. Chronic (long-term) stress can have real health consequences and should be addressed like any other health concern. Fortunately, research is showing that lifestyle changes and stress-reduction techniques can help people learn ...Read more
Nuclear stress: All tests have sensitivity and specificity and each lab has its own data. In the best labs these values for this test are >85% sens/spec., there are many technical factors. We choose tests by the information needed and the best test o get us what we need to know. ...Read more
Cardiac stress test: There are various drugs we use during cardiac stress testing with imaging. For routine treadmill or bicycle exercise stress testing without imaging, no drugs are used. When we do perfusion imaging we use thallium 201 or sestamibi for the imaging. We do use adenosine and other agents to facilitate the myocardial perfusion imaging especially if exercise isn't done. ...Read more
Depends: It depends what your doctor is looking for. Ultrasound, cardiac ct and MRI may be able to show how strong your heart is beating (ejection fraction) and if there is any wall motion abnormalities. Cardiac ct and MRI can even look at the vessels, which nuclear scans cannot. However, nuclear cardiac scans are considered the standard of care for looking at how well the blood perfuses the heart tissue. ...Read more
NO!!!!: Caffeine should not be ingested prior to pharmacologic cardiac stress since it can interfere with the results. Stopping caffeine ingestion for at least 24 hours prior to pharmacologic stress should be sufficient. If caffeine is ingested and pharmacologic stress is performed, this can cause false negative results. If you have taken caffeine, stress may be rescheduled or switched to dobutamine. ...Read more
Nope: There is radioactivity involved, but the dose is not considered in the range that it presents a risk and is comparable with other radiology exams. If a physician is ordering the exam, there is typically a good reason that would present more of a "risk" than the nuclear scan. I would not worry about the word "nuclear" in the test and take care of your heart. ...Read more
Like others, I dread the cardiac stress test or nuclear medicine test. What else is there that can better take its place at general 6 month exam? CT?
Test: Dread? First is the question of do you need any test? If there is some information needed for decision making, the question of which test then comes into play. Discussing suggested testing with your doc is best course. If the doctor doesn't need the information, you don't need the test. All tests have pluses and minuses but patients often ask for what they don't need. ...Read more
Pounding heartbeat very irritating. Cardiac exercise stress test no images and 48 hour holter monitor normal. What could be causing this?
I understand your distress.
Feel the Wonder of 3 Billion muscle cells working together to send blood with oxygen to all parts of your body due to which you are alive.
Feel good about Cardiac exercise stress test and holter monitor being normal.
“Pounding heartbeat” indicates overwhelming Anxiety due to stresses of life.

How accurate is a completed cardiac stress test in ruling out heart problems in a person with no personal or family history of heart disease?
Not very...: It looks like you are trying to predict a cardiac event in someone with a low probability of cardiac disease (a healthy person) the best example I can use is this. Can an eye exam predict a car crash? In people with normal eyes, probably not. But if the people you are all testing have eye problems, that eye test is much more predictive. If probability of heart disease is low, stress test less help. ...Read more
What does equivocal cardiac stress test mean in the results? I am a 47 year old male with hypertension controlled through medication. I completed the test reaching the target heart rate with no other symptoms. Test was part of an annual insurance check u
34 year old non-smoker having heart palpitations for a few months. Ekg and cardiac stress test negative. Anything else I should do?
Palpitation treat: Treatments include not using caffeine, alcohol, street drugs, smoking and other stimulant substances. Try to learn meditation and other calming techniques, cut out herbal substances, cough and cold medicines, nutritional supplements, see your doctor to be sure no direct heart problem and for treatment if the basics above don't help. ...Read more
Will cardiac stress test, and heart ultra sound show if I had atherosclerosis? Does homocysteine play any part with it?
Doctor gives cardiac stress test to everyone of his patients. Don't know what he's looking for. What's a less demanding heart pounding type test/scan?
Stress test: Why don't you discuss with the doc why he thinks you need a/the test and what decisions the test results will provide for. If you don't like the answer or if it isn't forthcoming, you might look for someone who will communicate with you. Treadmill tests are not a big deal and neither are heart scans but if you don't need the test, you don't need the test. ...Read more
Fluttery sensation n left side chest between nipple & armpit about 2inches above nipple. Last year for this had EKG & cardiac stress test & was normal
Pounding heartbeat very irritating. Cardiac exercise stress test no images and 48 hour holter monitor normal. Not anxiety can't fall asleep or woken?
For job I must rank top5% at cardiac stress test. Can a supplement with caffeine, theobromine, quercetin cause problems with healthy heart (ekg normal)?
Echocardiogram, cardiac stress test, Coronary CTA, chest X-Ray... Do these tests rule out structural heart disease? What can cause NSVT if all normal?
Does a normal exercise stress test mean there are no blockages and no coronary diseases? What percentage of blockage does it detect?
No: It should be performed to the maximum attainable functional capacity. ...Read more
↑ Heart rate & BP: Recording an ekg while walking up a steeper & steeper incline, at a faster & faster rate, so as to increase heart contraction intensity & rate of contraction, thus blood flow needed by the heart muscle. However, atherosclerosis does not narrow arteries, clots do, & the ekg only detects major qualitative differences in capillary blood flow. Thus only severe artery disease narrowing is ever detected. ...Read more
What is the difference between Cardiopulmonary exercise test vs Exercise stress test? Does Cardiopulmonary exercise test combines both and better?
Not better: Exercise stress tests measure your peak functional capacity and ischemia (blood supply), arrhythmias, and blood pressure response. The different tests are used for different issues. Cardiopulmonary stress tests also measures peak oxygen consumption which is useful for evaluating certain disorders, particularly prior to heart transplantation ...Read more
I'm 19 and received abnormal exercise stress test results. Is there anything that could have affected the test which may have caused the abnormal results?
YOu may have some congenital abnormality that has caused this problem You need to see a cardiologist and will probably require a heart cath to completely eval your heart. If this is then ok you should be in the clear. You could also have some type of viral cardiomyopathy (weak her muscle) that has caused this.
Best wishes. ...Read more
Exercise stress test. After ~1 min. Feet felt like heavy lead & worse as it went faster. Couldn't lift feet at end. Blacked out stumbling off. Why?
Coronary reserve: As a stress test progresses, the heart beats harder and faster which requires a richer and richer circulation provided by the coronary arteries. If need outstrips supply due to blockage, the test becomes abnormal. Thus a stress test is an indirect way to look for blockage. (a direct way is to fill the coronaries with dye and observe them directly) ...Read more

The cough reflex is a protective mechanism that uses muscles in your throat and chest to expel mucous and saliva that may contain pathogens that would otherwise possibly be inhaled via aerosol or to expel pathogens infecting the throat and respiratory system. Cough benefits the host by reducing load and benefits the pathogen which may then spread via aerosol. ...Read more
