INTRODUCTION AND AIM: The optimal length of stay for @entity1 with uncomplicated @entity583 ( @entity583 ) treated with primary percutaneous coronary intervention (PPCI) is still undetermined. The Zwolle risk score (ZRS) is a simple tool designed to identify @entity1 who can be safely discharged within 72 hours. The purpose of this study was to assess the applicability and performance of the ZRS in our population. METHODS: We studied 276 consecutive @entity1 (mean age 62  14 years, 75% male, 20% Killip class >1) admitted over a two-year period for @entity583 and treated with PPCI. ZRS, length of stay, 30-day mortality and readmission were obtained for all @entity1 . Low risk was defined as ZRS  <=3. RESULTS: The median ZRS was 3 (interquartile range [IQR] 1-4), with 171 @entity1 (62%) being classified as low risk. Thirty-day mortality was 4.7% (13 @entity1 ). Compared to other @entity1 , low-risk @entity1 had shorter length of stay (median 5.0 [IQR 4-7] vs. 7.0 [5-13] days, p<0.001), and lower 30-day mortality (0 vs. 12.4%, p<0.001), yielding a negative predictive value of 100% (95% CI 97.0-100%) for the proposed cutoff. The ZRS showed excellent discriminative power (C-statistic: 0.937, 95% CI 0.906-0.968, p<0.001), and good calibration against the original cohort. CONCLUSIONS: The ZRS appears to perform well in identifying low-risk @entity583 @entity1 who could be safely discharged within 72 hours of admission. Using the ZRS in our population could result in a more rational use of in- @entity1 resources.
