Accurate assessment of heart disease leads to earlier, more aggressive therapy

In a study comparing the ability of various medical techniques to accurately determine the extent of heart disease and stratify patients according to disease severity, researchers found that myocardial perfusion testing with gated single photon emission computed tomography (gated SPECT) was a more accurate predictor of prognosis in chronic ischemic heart disease (IHD)-a painful condition caused by a temporary reduction of oxygen-rich blood to the heart.
