Does adjuvant trastuzumab induce ventricular remodeling despite aerobic exercise training?
Initiation of adjuvant trastuzumab therapy is associated with LV cavity dilation and reduced ejection fraction despite aerobic exercise training. The long-term consequences of trastuzumab-induced LV remodeling and the means to prevent LV dysfunction require further study.
High annual hospital volume was consistently associated with lower stroke mortality. Our study encourages further research to determine whether this is due to differences in case mix, more organized care in high-volume facilities, or differences in the performance or in the processes of care among facilities.
