Hi I had a stress test done where they put the dye in my IV and my paper work says a small mild perfusion defect Of apical aspect of the anteroseptal ?

Hi I had a stress test done where they put the dye in my IV and my paper work says a small mild perfusion defect Of apical aspect of the anteroseptal ?

Perfusion defect: Hi, was the defect reversible or irreversible? The perfusion defect simply means that there is reduced blood flow to a part of the heart muscle, there are couple of possibilities including blockage in the artery feeding that area, an old heart attack or an artifact due to the test not being perfect or the heart muscle at that moment is hibernating due to chronic low blood flow, I suggest that you ...Read more

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

I'm having ankle surgery on Tuesday and a stress test the day before that doesn't use a treadmill. I'll be injected with dye. Will that conflict?

I'm having ankle surgery on Tuesday and a stress test the day before that doesn't use a treadmill.  I'll be injected with dye.  Will that conflict?

Stress test: The injectate is not dye but most likely to be a nuclear agent like Cardiolyte. It will not conflict with your ankle surgery. It will determine if you have coronary disease that places you at higher risk, and if so, delay the surgery until this is taken care of. Do it. ...Read more

Can a nuclear stress test cause you problems?

Can a nuclear stress test cause you problems?

Typically not: The only "risk" would be during the stress part, when one runs on a treadmill or gets a drug alternative. However, there is little risk here because this is monitored with an ekg and supervised by a cardiologist/nuclear physician. One drug that is used for stress even has an agent that can reverse its side effects. In summary, under normal standard-of care-conditions, there should be little risk. ...Read more

Can I have a stress test done without the nuclear medicine ?

Can I have a stress test done without the nuclear medicine ?

Not as good: Stress ekg is a very sensitive test and may show signs of stress induced ischemia, such as st depressions. However, it has low specificity, therefore your md won't be able to tell you where in your heart the problem likely is. Nuclear perfusion studies show defects in the myocardial walls giving more clues regarding the possible affected territory. ...Read more
