INTRODUCTION AND OBJECTIVES: In Spain there is little information available about @entity662 units for the treatment of @entity1 of low-to-medium risk with suspected @entity1187 . @entity1 AND METHOD: A prospective study was performed among emergency room @entity1 who complained about @entity662 and were suspected of suffering an @entity1187 with a normal or unspecific initial evaluation. They underwent an early submaximum stress test to decide on possible hospitalization. The follow-up time was 1 year. RESULTS: Of 472 emergency room @entity1 with suspected @entity1187 , 179 performed the stress-test during the first hours of the triggering @entity662 episode. None met the high-risk criteria for @entity1459 . In 78.8% of the cases, the test results were negative and the @entity1 were discharged. The results were positive in 15.1% and inconclusive in 6.1%; there were no complications during the procedure. @entity1 with a negative stress test had a more favorable outcome than the rest, with fewer following visits to the emergency room (11% vs 22%, p<0.001). One @entity1 with a negative stress test died of a @entity65 . None of the @entity1 suffered @entity583 during follow-up and 89% of the @entity1 with negative stress test had a favorable outcome (in terms of visits to the emergency room, @entity1459 , @entity583 , or @entity65 ). CONCLUSIONS: @entity662 units for the care of low-to-medium risk @entity1 with @entity662 allow a fast and safe hospital release with a favorable mid-term outcome.
