What is a Cardiolite Stress Test?
I have to go have this done tomorow. Has anyone ever had this done? What do i have to expect? Thank you.
Asked by Candance Schertz 2 years ago.
Cardiolite is something that they give you that is radioactive and is taken up by the cells of the heart wall (the myocardium) so that they can then take images of the heart during exercise to assess the blood flow to the heart. You will be given an injection of the Cartiolite (it's a preparation of thallium-201) and asked to walk on a treadmill until you have reached 85% of your maximum predicted heart rate, which depends on your age, gender and physical condition. There are a few different protocols depending on what they are looking for, but the most common one is for you to exercise, get your heart rate up, have the injection, and then they will do one set of images in the next 5 or 10 minutes. After they're finished, you stop, and then they do another set two or three hours later. But you would need to talk to your doctor or your test center about the details; as I said, there are other protocols they might be using. Good luck! I hope everything goes well.

What is the the difference between a lexiscan stress test and a cardiolite stress test ?
as far as im aware they are the same except no treadmill is required for the lexiscan nuclear test?
Asked by Ciara Altop 2 years ago.
cardiolite is an isotope that is injected before and during exercise so that it shows up in the heart to see if there are any blockages in the arteries. Lexiscan is a drug used along with cardiolite to make the heart act like it is exercising. It can be used as a resting treadmill and also with walking. It is used on patients that cannot walk on a treadmill or are walking on the treadmill and cannot walk long enough to get their target heart rate or the heart rate does not increase with exerecise usually because of drugs the patients are taking called beta blockers.

I think New Zealand because of their very bad result of test cricket. Recently England has defeated New Zealand very badly also their performance not like good now. So, I think New Zealand is the most under rated test cricket team in the world or I think South Africa is the most powerful test cricket team in the world. Answered by Maricela Doolittle 2 years ago.

WHAT CAN I EXPECT DURING THE CARDIOLITE NUCLEAR STRESS TEST? I AM A LITTLE APPREHENSIVE ABOUT THE PROCEDURE?
WHAT WILL I FEEL DURING THE NUCLEAR STREE TEST? WOULD I FEEL LIKE I'M HAVING A HEART ATTACK AFTER THE ISOTOPE INJECTION?
Asked by Dora Ximines 2 years ago.
no the isotope won't cause you to feel any different. You will be either asked to walk on treadmill or given a drug called persantin if you can not physically exercise. Its quite easy Answered by Van Dudenbostel 2 years ago.
Why do doctors tell people that Cardiolite heart scans are equal to a chest x-ray when they are really 3 rem?
Major organs -- 3 to 5 rem; some parts of the body get less. Check "radiation dose cardiolite" on the internet. Although the EDE is ~500 mrem, major organs get significantly more.
Asked by Tammy Tardio 2 years ago.
Diagnostic heart scans use about 40 millicuries of Tc-99m. Those injections cause about 3000 mrem, 3 rem, to a person; almost the Federal radiation worker annual limit. Yet doctors tell people that it is equivalent to a chest x-ray (i.e., 10 mrem). This leads doctors to prescribing these out like candy.....with no proper risk/benefit analysis (and they make big bucks). The public has no idea have radioactive they are after these, or that they have incurred significant radiation dose. Doctors are really "playing God" with these. Answered by Marisela Leardi 2 years ago.
A cardiolite scan exposes patient's to ionizing radiation, it is true. Why not request a stress echocardiogram with contrast instead? in many cases you get better information about perfusion, and wall motion, and zero radiation, at one quarter the cost. Doctors push the nuclear exam because they own the equipment, and it makes allot of money. PEACE, TJ Answered by Sherise Maudlin 2 years ago.
According to the web site below, you are off by an order of magnitude on your 3 rem estimate. Answered by Jordan Pherigo 2 years ago.
Question about Cardiolite?
I tried telling her we could just do it at my house, with no treadmill and just the kids, but it didn't work.....
Asked by Susan Rosenholm 2 years ago.
If Cardiolite is a "safe inert substance", with "no known medical side effects", why would a doctor instruct a patient to stay away from children after it is administered? That makes me a bit nervous.... Also, if you have had an exercise stress test, could you please describe how it went for you? Any bad experiences, side effects, etc.? Thanks. Answered by Merideth Kerins 2 years ago.
Don't know about cardiolite. I have went through the nuclear stress test a couple times; No harm done. I still missspell words. Answered by Tashina Bonomi 2 years ago.
Does it ever cause an odd taste in the mouth (especially when eating) a day or so after injection? Answered by Madge Nian 2 years ago.
maybe he wants you to stay away from children so you will pass the stress test? Answered by Latisha Settimo 2 years ago.
Different test results on electrocardiogram and CardioLite?
Sorry, It is Echo.
Asked by Kareem Sultemeier 2 years ago.
Electrocardiogram does not show EF. It must be Echocardiogram. Myocardial function tested on Cardiolite stress test is more reliable that one that is done on ordinary Echocardiogram as the technique is more advanced. Therefore, you can assume that your true Ejection Fraction(EF) is 55-60 which is normal. Good luck. Answered by Lauren Aldi 2 years ago.
You cannot measure ejection fraction from an ecg .The cardiolite showed a EF OF 55-60. It is slightly below normal but nothing to worry about. EDIT: good thing that you clarified that, the cardiolite is more accurate that the echo Answered by Simon Obert 2 years ago.
Definitely speak to you doctor. EF lower than 40% may indicate heart failure or some other problem. generally, most would say an EF above 80% is ok, but since your cardiolite EF was less than that, I would suggest speaking to your doctor right away. Are you on any medications that could be causing the fluctuation? (Digoxin, Beta-Blockers, Verapamil, Diltizaem, etc.?) Answered by Linnie Lebouf 2 years ago.
cardiolite tests are more reliable than conventional echo test. Answered by Mariam Winkelbauer 2 years ago.
Has anyone had a cardiolite stress test? I'm having one tomorrow morning & I'm slightly apprehensive?
Can you tell me what I can expect and if there are reactions to the cardiolite? Fear of the unknown I guess.
Asked by Tobi Kurtti 2 years ago.
you will be fine. the cardiolite you receive may make you feel flushed but other than that nothing to worry about. the test will take about 3 hours. Answered by Elina Lynah 2 years ago.
There are differn't kinds of stress tests. Cardiolite is the nuclear medicine that you recieve. You will get an injection when you first get there, you will wait a while then get the first set of pictures. After that you will either have a treadmill stress test or a chemical induced one. With the treadmill you will walk until you get to your target heart rate, when you get to your target (goes by your age) you will get the second dose of cardiolite you will walk another min or so and then be taken off. If you are doing the chemical induced one (there are diff kinds) you will probably feel flushed, some pressure in your chest, and might have some shortness of breath. Dont let it scare you. You are hooked up to an EKG machine the whole time. Half way through the chemical induced one you will get the second dose of nuclear med. After you are done with this part you will go back on the table for a second set of pictures. The first one is without the vessels opened up, the second one is with them opened up. The 2 are compared to see if the vessels do open up or not. Don't be scared. It is not that bad, and someone is with you the whole time. Good luck! Answered by Jerome Kasperski 2 years ago.
the best thing about the unknown is that you can find in in Yahoo Answers...or Google. Best of luck! BTW - How old are you? Answered by Shantay Beiler 2 years ago.

In Cardiolite stress testing, why do doctors not exercise pts. with a LBBB and instead use lexi or abutomine?
Asked by Kaye Topel 2 years ago.
A dobutamine stress test is a test that allows a patient who cannot walk on a treadmill or ride a bicycle to complete a stress test. The tracer (cardiolite) is utilized. Images are obtained before the dobutamine is infused and after the dobutamine is infused. This helps to determine if areas of the heart are receiving enough blood or if there are blockages (coronary artery disease). Answered by Nicolette Austill 2 years ago.
I had a Cardiolite Stress Test using a chemical stressor showing "inferior Ischemia" and "fixed apical defect"
I want to know what this means. I can't find an answer I can understand. I have an appt. with a cardiologist the day after tomorrow. Thank you
Asked by Cary Lorentz 2 years ago.
You most likely have a blockage in the Right Coronary Artery. That artery supplies the right Ventricle, which lies next to the diaphragm. It is inferior to the left ventricle.. The fixed apical defect means that you have had a complete blockage, or an almost complete blockage to a terminal segment of the artery going to the very tip of your heart. Exercise is supposed to dilate your arteries. So a fixed defect means that there was no ability to dilate that segment and to deliver further blood to that area. That means that you had a previous infarction (heart attack). The inferior ischemia indicates that there is not enough blood flow to the inferior portion of your heart. But in this case, the exercise dilates the blood vessel enough that blood flow picks up. So there isn't a fixed defect. I suspect that there is, or are several blockages. The one that is downstream has done its damage. The upstream blockage might be amenable to surgery or a stent. Not all heart attacks cause the classic symptoms of chest pain, anxiety and feelings of doom, radiation of pain to the left side, sweating and nausea. In the case of Right ventricular heart attacks, they generally have an atypical presentation - often presenting with sever nausea or vomiting, hiccups, etc. That's because, as I said, it sits on the diaphragm and so it gets confused (by the brain) with GI or stomach problems. You don't say how symptomatic you are. but the fact that you have had the Cardiolite stress test indicates that your cardiologist was worried about giving you an all-out exercise stress test. He was worried that that might have precipitated another heart attack. My guess is that a heart catheterization is in line for you. Answered by Rhea Kreisman 2 years ago.

Apical Ischemia Answered by Margorie Sweatt 2 years ago.
Wait for your appointment with your cardiologist. I think it means that you've probably had some kind of heart attack in the past, and likely still have coronary artery disease causing inferior ischemia. Ischemia is lack of blood flow to a certain area of your heart (the inferior part in your case), and usually correlates to a specific artery that provides blood to that part of the heart. Likely means your cardiologist will have a suggestion on how to help fix that one specific artery. Good luck! Answered by Kylee Garoner 2 years ago.
The fixed defect, if it is not an artifact, indicates irreversible loss of blood flow generally reflecting a prior heart attack. Inferior ischemia indicates that the inferior surface or base of your heart has impaired blood flow due to a blocked artery that has not resulted in a heart attack.

Has anyone ever had cardiolite reaction?
Has anyone had a reaction to Cardiolite? I had injections yesterday during a stress test ,and all night I felt like I couldn't get enough to drink. Today my tounge feels like its on fire. How long does this remain in your system, and how much radiation have I been exposed to?
Asked by Ramiro Cornmesser 2 years ago.
If you have an allergic reaction of sorts it usually occurs within mins not sometime the next day. The amount of radiation is equivalent to a CT scan so it's really not that much. The half life is 6.02 hrs so it remains in the system for approx 2 days. Answered by Libby Kimball 2 years ago.
