Prediction of all-cause mortality in women with known or suspected coronary artery disease by stress technetium-99m tetrofosmin myocardial perfusion imaging

We studied the incremental value of stress technetium-99m tetrofosmin imaging for predicting all-cause mortality in 503 women (aged 58 ± 12 years) with known or suspected coronary artery disease. The annual mortality rate was 1.4% with normal perfusion and 4% with abnormal perfusion (p <0.01) during a follow-up of 3.5 ± 1.2 years. In an incremental multivariate analysis model, clinical predictors of mortality were age, diabetes mellitus, smoking, and a lower systolic blood pressure during stress. An abnormal scan was incremental to clinical data in predicting mortality.
