Still to decide

Just a few days ago I put a question on the site about whether I should go for a Myo Cardio Perfusion test and there was some great advice but I still can't decide and it is the night before.Hi DD 13 I got in touch , eventually with specialists. When my Cardio specialist finally got back to me he told me about another type of test and also sympathised with my worries. He did not consult with my thoracic consultant who knows about my bronchiastasis . My GP also fudged the issue and both of them said it was down to me!!!!! I feel guilty about wasting NHS time and resources but the cardio specialist didn't get through to me until friday afternoon . Being a teacher didn't help. I now realise that I have had 2 CT scans an angiogram/angioplast and a normal x ray within the last year. Do people still think I should go ahead with the Nuclear Myo Cardio gram.

I am at my wits end making this decision.

Thanks for listening

Hi Stan2, I had this test on 13 th December 2018...it does take a few hours but most of that is spent sitting around. The stress part of the test is done in 3 minute blocks up to a maximum of 12 minutes, I only managed six minutes on a treadmill, it could be an exercise bike though, I was told they need at least six minutes as they have to inject a second isotope at 1 minute before the end of the test. It is a moderate walking pace on an incline not a run.

Hope this helps, I did not have any adverse effects and the scan itself is more like a small ct scanner then an mri so not too enclosed...


Hi Bassman65

Did you worry about the radiation at all?



Not really, you have to have something to eat and drink after each isotope to stop it getting where it shouldn’t

It is a very common procedure these days and less invasive than having and angiogram with wire pressure sensor


Did you have lots of Ct scans before hand ? Why did they miss out the angiogram?

sorry about being nosey?



I had an echocardiogram followed by an angiogram: this showed a mild to moderate atheroma in one artery and extreme slow blood flow in all three. Initially they were going to do a second angiogram inserting a very fine wire to measure the pressure either side of the artery.

In the end they opted for the MPS instead as it is basically the same test (so they told me) but much less invasive and you don’t need 4 days off work afterwards....


The radiation is really not an issue. The test, imo, is the most useful noninvasive diagnostic tool cardiologists have available to them to determine if you have reduced blood flow in your coronary arteries. It sounds as though this may weigh upon your mind if you do not have the test. That being said, I would have the test for peace of mind. If the test does identify an issue that needs to be addressed you'll get the care you need and be just fine. If coronary problems are identified before a cardiovascular event has occurred, they can usually be remedied with great success. Good luck and be well.


Hi Stan,

It really is nothing to worry about, I have had an AVM in my brain zapped using Gamma Radiation with no ill effects !!! I have also had a Myocardial Perfusion scan + Angiography. Prior to CABG surgery the Surgeon wouldn't commit until the Neuro Surgeon had carried out a scan to confirm the AVM had been obliterated. This was because of the use of Heparin to thin my blood during the by pass surgery. Don't worry they probably carry out 1000s a week across the World without any problems.


Hi Prada

Thanks for replying

I am not really worried about anything going wrong. I am just very worried about having so much Radiation in the past year that I may now fall into the dangerous zone of being at risk from cancer.

Kind regards



I can understand your unease about not being exposed too much radiation.

I had to have a CT recently they included an another test whilst I was there to prevent me being exposed repeatedly to radition.

It was however very reassuring to find out everything was normal and my new pain was related to my ongoing heart problem.

Perhaps discuss this issue with the Radiographer carrying out the test?

They are specialists who should know.
