Stress (Definition)

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

Radiotracers such as thallium or technetium sestamibi (cardiolite) are injected intravenously and travel through blood to heart muscle.2 sets of images are made during rest and exercise and compared. Indications for this study include chest pain, previous heart attack, heart surgery and coronary artery disease ...Read more

Tomorrow i'm getting a nuclear stress test w cardiolite. Worried about side effects and reaction to the thallium or whatever they use. Should i worry?

Isotopes quite safe: Dyes are not used during nuclear stress tests. Trace radioactive isotopes are but there are no significant reactions to these minute doses used considering the thousands of tests done around the globe daily unless one has a history of being allergic to the thallium or cardiolite. ...Read more

What to do if I'm 53 y/o white female with vice like chest pain,numbness & tingling & perspiration..cardiolite stress normal..what is going on?

Poss false negative: Cardiolyte stress tests in the best laboratories in the world only have 80% sensitivity. You don't mention if your pain is exertional. That aspect of pain is far more important than the other descriptors you use. You need a coronary angiogram to clear the air. It may be normal. Your pain may not be of cardiac origin. But there is a valid indication here to find out. ...Read more

Getting a stress echo done next week. Can thallium (cardiolite) cause a heart attack or is it the actual activity that can cause ha during testing?

Stress testing: The circulation of the heart is evaluated by stress testing. Walking on a treadmill or injection of medicine has the effect of stressing the heart muscle. Sometimes additional information is obtained by simultaneously imaging the heart using ultrasound or injecting a nuclear isotope and scanning the heart with a special nuclear camera. The tests are safe and provide very useful information. ...Read more

How good is a cardiolite study for detecting potential heart attack?

How good is a cardiolite study for detecting potential heart attack?

Stress thallium: The study is made to look at the possibility of clogged arteries in the heart that can be more discernible with exercise or stress. If distribution of dye is poorer in some areas, these have to be defined with angiogram to be able to treat them. If there is diffuse disease and equalization, it can miss. If there are collaterals the area would still look good. It is not to predict mi, only vessels. ...Read more
