Applicability of the Zwolle risk score for safe early discharge after primary percutaneous coronary intervention in ST-segment elevation myocardial infarction

Abstract

The ZRS appears to perform well in identifying low-risk STEMI patients 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-patient resources.

Value-Based ST-Segment–Elevation Myocardial Infarction Care Using Risk-Guided Triage and Early Discharge

“…One Spanish study examined 276 patients with the Zwolle Risk Score, however, only did so retrospectively. 6 A prospective study from the same country looked only at low-risk patients, of which just 54 were targeted for early discharge, with no assessment of effect on cost. 12 The Safe-Depart Trial studied prospective implementation of the Zwolle Score in a Canadian hospital, but only 54 patients were enrolled, of whom just 27 had the risk score applied to their care.…”

Safety of early discharge after primary angioplasty in low-risk patients with ST-segment elevation myocardial infarction: A meta-analysis of randomised controlled trials

“…The ZRS has been validated in several studies and can be used in up to 60% of all STEMI patients. 11,22,23 In this metaanalysis, the study by Melberg et al 13 and the EDAMI trial used the ZRS to identify low-risk STEMI patients (ZRS 3). The PAMI-II criteria designate as low-risk STEMI patients aged 70 years or less, with a left ventricular ejection fraction greater than 45%, one or twovessel disease, successful PCI and no persistent arrhythmias.…”

2020 Clinical practice guidelines for Acute ST-segment elevation myocardial infarction

“…Показано, что данные факторы являются независимыми предикторами 30-дневной смертности. Пациенты с ≤3 баллами по шкале Zwolle имеют 0,5% риск 30-дневной смертности и могут быть безопасно выписаны из стационара в первые 72 ч. Валидность шкалы Zwolle была показана в целом ряде исследований [295][296][297][298].…”
