SPECT MPI may not be necessary for older patients who can achieve a given exertion level during an exercise stress test without showing indications of cardiovascular distress or heart disease, according to findings presented at a nuclear cardiology meeting. The study, which reviewed data on 24,689 patients, developed hypothetical parameters for patients to undergo MPI and radioisotope injection. In assessing patient data, researchers found that using their guidelines, 1,561 patients considered eligible for injection did not need it. Researchers said their parameters may help reduce radiation exposure and costs.
