Key result
Myocardial perfusion scintigraphy predicts event-free survival better than angiography in women with positive stress tests.
Why the study?
Does myocardial perfusion scintigraphy provide better prognostic value than coronary angiography in women with suspected CAD and positive stress test results?
Observational (n=115)
Does myocardial perfusion scintigraphy provide better prognostic value than coronary angiography in women with suspected CAD and positive stress test results?
Absolute Event Rate: 93.9% vs 89.7%
p-value: p=<0.01
Myocardial perfusion scintigraphy offers superior prognostic value compared to coronary angiography for predicting cardiovascular events and the need for revascularization in women with suspected CAD and positive stress tests.
MPS may better stratify revascularization risk than angiography in women with positive stress tests; leaves open whether it should alter diagnostic pathways.

Miernik et al. (2012) conducted an observational in Suspected coronary artery disease with positive ECG stress test results (n=115). Myocardial perfusion scintigraphy vs. Coronary angiography was evaluated on Survival without cardiovascular events (p=<0.01). Myocardial perfusion scintigraphy was a significantly better predictor of survival without cardiovascular events than coronary angiography in women with positive stress test results.
