Coping, Mood, Quality of Life, and Outcomes in Recipients of Left Ventricular Assist Devices: A Cluster Analysis

Objective: Left ventricular assist devices (LVADs) are increasingly used for temporary circulatory support until transplant or as destination therapy for patients with end-stage heart failure. Understanding patients' attitudes and resources is crucial to support them. Methods: Sixty-one LVAD recipients (55 [10] years, 10% women, 15% destination therapy) participating in cardiac rehabilitation (CR) postimplant underwent assessment of coping styles (Coping Orientation for Problem Experiences), quality of life (Medical Outcomes Study Short-Form 36, Minnesota Living with Heart Failure Questionnaire), and mood (Hospital Anxiety and Depression Scale). Results: Cluster analysis identified two homogeneous groups: C1 (n = 18) patients had higher anxiety (9.6 [5.0] versus 4.0 [2.7], p < .001), depression (10 [3.0] versus 4 [2.7], p < .001), and avoidant coping (29 [5.2] versus 21.2 [3.8], p < .001) scores and worse quality of life (Short-Form 36 of the Medical Outcomes Study Physical Component Scale 31 [5.3] versus 35.6 [6.9], p < .001; Mental Component Scale 34.3 [6.8] versus 50.3 [8], p < .001; MLHFQ physical 26 [7.2] versus 13.9 [8.2], p < .001; emotional 17.7 [3.4] versus 3.86 [3.2], p
