Clinical risk assessment after first myocardial infarction--is additional noninvasive testing necessary?
In order to assess whether the outcome of MI can be predicted by clinical data alone or whether and how much noninvasive testing is necessary to predict cardiac events or death, 361 patients were prospectively evaluated and followed for up to five years. A recursive partitioning analysis indicated that high-risk patients can be identified clinically after MI with a high degree of accuracy; to separate low-risk patients who need no further investigation or therapy, however, one additional noninvasive test is necessary which allows quantification of myocardial damage as well as exercise-induced ischemia. Additional tests added little to this risk prediction, indicating that multiple noninvasive testing should not be performed.
