title: Towards evidence-based emergency medicine: Best BETs from the Manchester Royal Infirmary. BET 2: Is there value in testing troponin levels after ICD discharge?
abstract: A short cut review was carried out to establish whether testing for troponin levels is useful after discharge of an Implanted Cardioverter-Defibrillator (ICD). Many papers were found using the reported searches, none of which directly addressed the problem but some 13 presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of those best papers are tabulated. It is concluded that the number of ICD discharges must be taken into account when evaluating any troponin level rise. Overall a positive troponin assay post ICD discharge is independently associated with an increased mortality.
