Outcome Measures
Our primary outcome was post-LVAD implantation all-cause inpatient
mortality. Secondary outcomes of interest were intraoperative cardiac
arrest, post-procedure ischemic stroke, post-procedure thromboembolism,
infections, major gastrointestinal (GI) bleeding, cardiac complications
(such as pericardial complications, complete heart block and insertion
of permanent pacemaker), short-term percutaneous mechanical circulatory
support (PCMS), implant-related complications and acute kidney injury
(AKI) for index hospitalization during which patients received LVADs.
Detailed methods, including covariate ascertainment, are included under
the Data Supplement.
