Long-Term Survival After LVAD Implantation in End-Stage Heart Failure

Sponsor: The Affiliated Nanjing Drum Tower Hospital of Nanjing University Medical School

Summary

This is a prospective, observational, multi-center cohort study designed to evaluate long-term survival and clinical outcomes in patients with end-stage heart failure undergoing left ventricular assist device (LVAD) implantation. Patients receiving LVAD implantation as part of routine clinical care will be enrolled and followed for up to 3-5 years. During the study period, data will be collected on baseline characteristics, preoperative medical therapy, intraoperative surgical information, in-hospital course, and long-term postoperative medication use, as well as survival status, major clinical outcomes, LVAD-related complications, and hospital readmissions. In addition, myocardial tissue samples will be obtained from the left ventricular apex during LVAD implantation surgery. These tissue samples are routinely removed as part of the standard surgical procedure and would otherwise be discarded after pathological examination. Peripheral blood samples will also be collected at predefined time points as part of routine clinical blood testing. No additional surgical procedures or invasive interventions are required for this study. This study does not involve any experimental treatment or changes to standard medical care. All treatments and follow-up assessments are determined by the treating physicians according to routine clinical practice. The purpose of this study is to improve understanding of long-term outcomes after LVAD implantation and to explore potential biological factors associated with prognosis in patients with end-stage heart failure.
