BACKGROUND: Studies have shown mortality benefit for @entity737 ( @entity737 ) in @entity583 ( @entity583 ) @entity1 with reduced left ventricular ejection fraction (LVEF), but contemporary eligibility and appropriate utilization of @entity737 is unknown. OBJECTIVE: The purpose of this study was to determine the contemporary eligibility and appropriate utilization of @entity737 post- @entity583 . METHODS: Using the prospective Minneapolis Heart Institute regional @entity583 registry, LVEF before discharge and at follow-up were stratified into 3 groups: normal (LVEF >= 50%), mildly reduced (LVEF 35%-49%), and severely reduced (LVEF <35%). RESULTS: From March 2003 to June 2012, 3626 @entity1 were treated. @entity1 with in-hospital death (n = 187), @entity1479 in place (n = 21), negative cardiac biomarkers (n = 337), and undocumented in-hospital LVEF (n = 9) were excluded, leaving 3072 @entity1 in the final analysis, including 1833 (59.7%) with LVEF >= 50%, 875 (28.5%) with LVEF between 35% and 49%, and 364 (11.8%) with LVEF <35% before hospital discharge. Overall, 1029 @entity1 (33.5%) underwent follow-up echocardiography >= 40 days post- @entity583 , including 140 of the 364 @entity1 (38.5%) discharged with LVEF <35%. In total, 73 @entity1 (7.1%) with follow-up echocardiography >= 40 days post- @entity583 met criteria for an @entity1479 (68 LVEF  <=30%, 5 LVEF 30%-35%, and New York Heart Association class II or greater). Only 26 of these @entity1 (35.6%) underwent @entity1479 placement within 1 year post- @entity583 . Overall, only 10% to 15% of potentially eligible @entity1 had an @entity1479 implemented. CONCLUSION: Rates of @entity1479 implantation in appropriate @entity583 @entity1 after 40 days are low. Strategies are needed to identify and expand access to these high-risk @entity1 .
