Stress Test Sheds Light on Survival Odds

September 11, 2012

The ability to perform a stress exercise test strongly predicts survival, but an inability to complete the test may be diagnostic for severe disease, according to two Brazilian studies.

In one study, 11.6% of 391 patients who did not reach 85% of their maximum heart rate had higher ischemia scores on SPECT myocardial perfusion imaging compared with those who completed the test, reported Andrea De Lorenzo, MD, of Clinica de Diagnostico por Imagem in Rio de Janeiro, and colleagues.
