plantation rule, patients aged >60 years at the time of wait list entry are been being treated nominally with bridge-totransplantation therapy (BTT) but practically with DT. To achieve better clinical results at introduction of DT in Japan, the clinical results and adverse events in these DT patients should be evaluated.In the present study, we compared the clinical results of patients aged >60 years at LVAD implantation with younger patients, and analyzed the adverse events and change of end-organ function on long-term follow-up using a national database.
Use of a left ventricular assist device (LVAD) has become standard therapy for end-stage congestive heart failure. 1-6 Age has been shown to have an adverse impact on long-term clinical results for continuousflow LVAD, 2,7,8 but the age at which the risk of an LVAD becomes unacceptable is undefined. Furthermore, studies on the risk factors for mortality after LVAD implantation specifically in elderly patients, are very limited. 8 In Japan, destination therapy (DT) will be approved by the Ministry of Health, Labor and Welfare in the near future but, because of donor shortage and national trans- Yoshiki Sawa, MD, PhD on behalf of the Japanese HeartMateII Investigators Background: Advanced age has an adverse impact on clinical results in left ventricular assist device (LVAD) patients. We compared the clinical results of patients aged >60 years with younger patients using a national Japanese database.
Methods and Results:Between April 2013 and December 2016, 300 patients underwent HeartMateII implantation. Of these, 37 patients were ≥60 years at LVAD implantation, and the clinical results of these patients were compared with the other younger 263 patients. At 1 and 3 years the on-device survival was 95%, 91% in younger patients, and 85%, 75% in older patients, respectively (P=0.016), although age was not a risk factor on the multivariate analysis. There was no significant difference between the groups in incidence of various adverse events except stroke. In the propensity-matching cohort, the incidence of stroke was significantly higher in patients aged >60 years (P=0.047). In patients aged >60 years, improvement of renal function was transient and there was no improvement later than 3 months, and recovery of serum albumin level to preoperative value was delayed.Conclusions: There were significant differences in the stroke incidence and recovery of end-organ functions after LVAD implantation. This may have important implications for patient selection in future destination therapy in Japan, where quality of life is an important issue in LVAD support.
