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
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
Extremely lightheaded after Cardiac stress test, but it came back completely normal. Report showed no abnormalities. Is the lightheadedness okay?
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 moreSee 1 more doctor answer
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

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 moreSee 1 more doctor answer
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
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 ...Read more
