Figure . Freedom from the primary end point defined by all‐cause mortality, rehospitalization for acute heart failure, heart transplantation, and mechanical circulatory support implantation.

Kaplan–Meier survival curves for freedom from the primary end point are plotted and compared according to the group of quality of life. Patients with low QoL experienced severe cardiovascular events more frequently (logrank P=0.013). QoL indicates quality of life.
