Syndrome X defines a group of patients who present typical angina pectoris,positive exercise test and normal coronary arteriogram.In studies with Thallium 201 in these patients,incidence of appearance of reversible deffects showing a reduction in blood flow reserve is less than 20%.The purpose of this study is to asses the result of Thallium scan and washout in subjects with Syndrome X.24 patients selected from those undergoing diagnostic angiography for typical angina who had normal arteriograms were studied with Thallium 201 SPET to evaluate uptake and washout.Washout was calculated applying the formula stress uptake-redistribution uptake / stress uptake.
Thallium defects were found in 3/24 and washout defects in 22/24. There is a statistically significative reduction ( p<0,0.5 ) in thallium uptake and washout in patients with syndrome X compared to a control group.
| Thallium scans | Syndrome X | Controls |
| Mean Stress counts | 83.72 | 111.99 |
| Mean Redistribution counts | 86.2 | 108.13 |
| Washout | -3.11 | 3.44 |
Conclusion: The visual analysis of Tallium-201 slices is of limited value in patients with syndrome X.Analysis of Thallium 201 washout provides additional information.
