thallium stress test Report.. Please Tell me the conclusion of Report ? do I need angiography ?
Dipyridamole myoview spect myocardial perfusion study
Age / Sex : 65/M
Indication: HTN, DM, ? IHD
Isotope : 7mCi of Tc-99m Myoview at peak stress
21mCi of Tc-99m Myoview at rest
Persantin Infusion Stress: Pharmacological Intervention was performed with injection persantin (Dipyridamole) at a rate of 0.142 mg/kg/min, 07 Mci of Tc-99m Myoview was given I/V. His resting ECG showed 0.5-1mm ST-T Depression in inferolateral leads. No further ECG changes were noted during and after persantin infusion. After 1-min slow rose from 76/min to 82/min and BO increased from 130/80 mmHg to 14/80 mmHg SPECT images were acuired around an arc of 180 (RAO=LPO)
Scan Interprentation: Stress images show a medium to large sized perfusion defect of moderate to high severity involving the apex, leteral and inferior wall. There is no evidence of reversibility of the apical inferior wall shile evidence of good reversibility is noted over the other mentioned defects on rest images. remaining LV moocardiym is LV cavity is dilated in stress images (transient ischemic dilatation)
Conclusion: Myocardial perfusion SPECT with dipyridamole intervention is a large sized dnducible ischemia of moderate to hight severity involving the apex. lateral and mid medium sized infarct is noted over the apical inferior wall
Most of us aren't health professionals and aren't qualified to make recommendations. What did your doctor recommend?
That said, I've learned from having heart disease there are certain key words that would get my attention and want more information, as one would learn from an Angiography. Some of those words are mentioned in your report, such as 'defect of moderate to high severity', 'no evidence of reversibility' and 'evidence of good reversibility', mid medium sized infarct'.
The test you've just had is called a nuclear perfusion scan and it basically involved putting a radioactive contrast into your blood stream which will find its way into your cells. This contrast is called Thallium and the ideology being, if there is no thallium in a group of cells, then they are going to be dead. This is because they have been without a blood supply for too long, the vessel supplying those cells is blocked. The thallium doesn't stay in your body very long after. I notice from the report that you had persantine injected to stress your heart, rather than use a treadmill. Anyway, your report...
I don't know if you have had an angiogram yet, but if not, I think you definitely need one now. It looks as though you have had a previous heart attack and some muscle is termed as irreversible, meaning it took no thallium into the cells. Some of that area is reversible, probably a slight glow on the images, suggesting a blockage is restricting flow to another large area. The part which has suffered a heart attack appears to be a medium sized area at the back of the left ventricle at the bottom. The good news is that with intervention (stents or bypass) the rest of the left ventricle can be saved. The area which requires blood flow increased is quite substantial. Your left ventricle is dilated, but that's hardly surprising with it trying to compensate.
Have they booked you for angiography yet?
Thank you soo much Mr. Ed34, Actually my appointment with dr is on coming monday so I was just taking an idea about my report... Anyway, what i could understand with your comments that my Dr will definatly suggest me for Angiography... anyway, thanks again
yes. doctor recommend Angeoghraphy.. but tell me your openion that how much stents will be needed ? dr said that possibily there will be one or two stents will be needed.. but actual figure will come after angeo..
What you say ?
I think that stenting will be wise, because your tissue (heart muscle) is showing signs of suffering oxygen loss and this needs to be restored to help the muscle recover.
If you need 2 stents or more, I would seriously consider having it done. I certainly would. I would also look at serious lifestyle changes. Diet, stress, regular exercise etc.
