A study presented at ASNC2013 affirms the safety of limiting the use of myocardial perfusion imaging in low-risk angina patients to those who fail an exercise stress test. Patients who passed a stress test, were younger than 65 and had normal ECG findings and no history of coronary artery disease were eligible to skip MPI, a strategy that could lower costs and limit radiation exposure. However, MPI findings for those not eligible to skip the test were normal in 94.6% of cases, suggesting additional criteria might be warranted, according to one expert.
