53 yr old and just got results from a nuclear stress test. Findings showed SPEC images showed medium perfusion abnormality of moderate intensity in the basal and mid anterior myocardial walls on the stress images. The defect is present on the resting images consistent with prior myocardial infraction,. Gated SPECT images reveals diminished myocardial thickening and wall motion of anterior wall. There is no stress transcient ischemic dilation of left ventricle. TID index 1,04 lV volume 47 ml the left ventricular ejection fraction was calculated or visually estimated at 70%
///impression--70myocardial perfusion imaging is abnormal. there is a moderate area of infarction in the basal anterior and midanterior myocardial walls, the left ventricular ejection fraction was calculated or visually estimated at 70% TID index normal normal lv volume
i am waiting on doctors results can you please explain what this all means and treatments thanks
Without being able to review your entire chart/history it will not be possible to give you an exact answer, but generally speaking having a fixed defect (i.e. perfusion abnormalities on both the rest and stress images) usually represents one of two possibilities.
1) You may have had a prior heart attack and therefore that area of the heart takes up less of the nuclear tracer
2) This finding may be artifact (false positive)
All non-invasive testing modalities have inherent limitations. Nuclear stress testing can occasionally give false positive results due to artifact and therefore the interpretation of the test information by your physician who has access to all of the clinical information is key.
I would recommend you have a detailed discussion with your physician who ordered the test on how best to proceed.
