Hi ladies,

    I need your help. My Dr wants me to have a chemical stress test. I am afraid to have it. My breathing is not good enough to do a regular one. He don't think I can get my heart rate up high enough. So he want the chemical test. I am afraid of the chemicals. My Mother had a bad heart. They gave her a chemical stress test and it gave her a heart attack. made her sick, and a ragging migraine for days after. I do not want to have a heart attack. I don't know it I want this being on chemo and with all my other problems. I have Mets to lungs and spine. The cancer is is remission right now. I am left with allot of scare tissues in my lungs. Under stress my heart rate goes up fast and my oxygen drops fast. I am scared that I wont be in control. And will pass out or some thing will happen to send me to the hospital again.

Is there any one here that has had this test while on chemo, with a breathing problem. What was the procedure. Did it hurt.

Side effects?? I have researched and found horror stories. I need more info to make my decision.

What is a "chemical stress test"?  I've never heard of one.

Hi Kay,

 I cannot comments on chemical stress test, however I think you should talk openly with your doctor. You have strong family history plus undergoing Chemo and it should be taken into consideration . Please see cardiologist and discuss your concerns, maybe there ion another test which can be used to answer the same question. I have had stress echo only.

hugs

Hi Kay,

I never heard of a chemical stress test either.  I know Herceptin can damage the heart and assume that Perjeta might be in that category too  I would have a frank talk with the oncologist stating exactly your reasons of concerns and go from there.

By using Google this is what I found, don't know if it will help.  Best to you, Doris

Adenosine Stress Test

Patients who cannot exercise must undergo a pharmacological stress test consisting of medication known as adenosine. The Cleveland Clinic states that adenosine works by dilating the blood vessels leading to the heart, which increases blood flow, thus stimulating exercise. Adenosine essentially mimics exercise immediately after it's taken. During "exercise," a small amount of a radioactive tracer is injected into the patient's vein. A special camera then detects the radiation released by the tracer to produce images of the heart on a monitor, according to the Cleveland Clinic. 
This test allows doctors to determine how adequately the heart distributes blood flow during stress versus at rest and in diagnosing coronary artery disease.

 

Nuclear Stress Test

A nuclear stress test measures blood flow to the heart muscle, according to the Mayo Clinic. The Mayo Clinic states that a nuclear stress test involves injecting a patient with a medication that increases the blood flow to his heart muscle, essentially stimulating exercise. A special camera produces clear pictures of the heart tissue on a monitor. These images show areas of low blood flow and areas of damaged heart muscle. The images of the heart are taken during the stress phase and during the rest phase. 
A nuclear stress test shows how well the heart works during stress (exercise) and at rest. Nuclear stress tests help doctors to diagnose coronary artery disease and heart enlargement, so doctors can devise a proper treatment plan.

 

Stress Echocardiogram

Medline Plus states that a stress echocardiogram determines how well the heart muscle responds to stress. A stress echocardiogram uses ultrasound imaging to show whether the heart is receiving enough blood flow and oxygen while under stress. Doctors can discover and potentially treat any blockage or disease from the results of a stress echocardiogram. 
Medline Plus states that doctors typically refer patients who have symptoms of recent chest pain, recently had a heart attack, those at high risk for heart disease and those who have valve problems to have a stress echocardiogram.

I agree with discussing your concerns with a cardiologist.  In fact, you might want to print your post and have the cardiologist read it...you expressed yourself very well.

I wonder if a MUGA scan would get the docs the information they need....

Please let us know what you decide so we can get on that pink bus.

Hugs,

Linda

I'm having it on the 15th the first part. It is called a Lexi-scan. It won't make my heart race he don't think I can do that part because of the scare tissue in my lungs. So it will just dilate the arteries. He needs to see if there is any blockage or thickening. He is thinking that the Radiation damaged my heart or arteries. I was burned very bad by rads. I am praying that what ever it is meds will take care of it. He says worst case scenario I will need a stint or bypass surgery. God I hope not....I will keep you all posted.

Thanks you all.
Kay

Your plate is already so full.  I do hope you don't need surgery.  I am sorry that the rads burned you so badly.  I really wonder why it is necessary to radiate the chest at all.

Best,

 

Doris

HI Doris,

I know what you mean about Rads, If I had known then what I know now I would not have had rads at all. I found out much later that my Rads Oncologist wasn't even licensed in this state!!

Hope you are feeling well.

Take care darlin

Kay,

I have had both and the chemical one was way easier.  You have a Dr. right there administering it and my understanding that if I had any problems he could quickly stop the test.

I am so sorry to hear about your problems.  I can't help much because I didn't even know what a Lexiscan was but I looked it up and found a list of side effects.  Hope this helps and sending hugs and prayers!
