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.
