Impact of Different Therapeutic Strategies With Left Ventricular Assist Devices on Health-Related Quality of Life During Prolonged Device-Based Support.

ABSTRACT: Background: Left ventricular assist device (LVAD) implantation improves survival and health-related quality of life (HRQoL) of patients with heart failure. However, the impact of LVADs or different LVAD-based therapeutic strategies on long-term HRQoL has not been investigated. We evaluated the long-term HRQoL of Japanese patients who were treated with different LVAD-based therapeutic strategies. Methods and Results: Patients whose data were recorded in the Japanese Registry for Mechanical Assisted Circulatory Support between January 2010 and December 2018 were divided into 3 groups: primary implantable LVAD (G-iLVAD; n=483), primary paracorporeal LVAD (n=33), and bridge-to-bridge from paracorporeal to implantable LVAD (n=65). HRQoL was evaluated using the EuroQoL 5-dimension 3-level (EQ-5D-3L) before and 3 and 12 months after LVAD implantation; the mean EQ-5D-3L visual analog scale (VAS) score in the G-iLVAD group at these time points was 47.4, 71.1, and 72.9, respectively (where scores of 0 and 100 indicate worst and best imaginable health state, respectively). Changes in the least squares means of the VAS scores at 3 and 12 months after implantation differed significantly among the 3 groups. Social function, disability, and physical and mental problems were significantly lower in the G-iLVAD than other groups. Conclusions: HRQoL improved significantly at 3 and 12 months after LVAD implantation in all groups. Physical function showed a stronger improvement than did social function, disability, and mental function.

Project description:AimsDonor heart shortage leads to increasing use of left ventricular assist device (LVAD) as bridge-to-transplant or destination therapy. Prolonged LVAD support is associated with aortic valve insufficiency, representing a relevant clinical problem in LVAD patients. Nevertheless, the impact of LVAD support on inflammation, remodelling, and chondro-osteogenic differentiation of the aortic valve is still not clearly understood. The aim of the study is to evaluate the impact of LVAD support on structural and molecular alterations of the aortic valve.Methods and resultsDuring heart transplantation, aortic valves of 63 heart failure patients without (n = 22) and with LVAD support (n = 41) were collected and used for analysis. Data on clinical course as well as echocardiographic data were analysed. Calcification and markers of remodelling, chondro-osteogenic differentiation, and inflammation were evaluated by computed tomography, by mRNA analysis and by histology and immunohistochemistry. Expression of inflammation markers of the LVAD group was analysed with regard to levels of C-reactive protein and driveline infections. Calcium accumulation and mRNA expression of determined markers were correlated with duration of LVAD support. Data were also analysed relating to aortic valve opening and aortic valve insufficiency. There was no difference in the frequency of cardiovascular risk factors or comorbidities between the patient groups. Expression of matrix metalloproteinase-9 (P = 0.007), alpha-smooth muscle actin (P = 0.045), and osteopontin (P = 0.003) were up-regulated in aortic valves of LVAD patients. Histological appearance of the aortic valve was similar in patients with or without LVAD, and computed tomography-based analysis not yet revealed significant difference in tissue calcification. Expression of interferon gamma (P = 0.004), interleukin-1 beta (P < 0.0001), and tumour necrosis factor alpha (P = 0.04) was up-regulated in aortic valves of LVAD patients without concomitant inflammatory cell infiltration and independent from unspecific inflammation. Expression of matrix metalloproteinase-2 (P = 0.038) and transforming growth factor beta (P = 0.0504) correlated negatively with duration of LVAD support. Presence of aortic valve insufficiency led to a significantly higher expression of interferon gamma (P = 0.007) in LVAD patients. There was no alteration in the determined markers in relation to aortic valve opening in LVAD patients.ConclusionsLeft ventricular assist device support leads to signs of early aortic valve degeneration independent of support duration. Thus, the aortic valve of patients with LVAD support should be closely monitored, particularly in patients receiving destination therapy as well as in the prospect of using aortic valves of LVAD patients as homografts in case of bridge-to-transplant therapy.
