AbstractIn patients who have end-stage heart failure, medical therapy is of limited use, and heart transplantation is frequently not an option because of the shortage of donor hearts. Two new treatment options, left ventricular assist devices (LVADs) and implantable cardiac resynchronization therapy (CRT) devices, can improve survival and quality of life in patients who have heart failure. Both types of devices are easy to implant. However, LVADs carry the risk of infection and mechanical failure, and CRT is ineffective in a substantial proportion of patients who have heart failure. Therefore, methods must be devised to identify patients who have heart failure who are likely to benefit from these devices. Data suggest that early LVAD implantation, before end-stage heart failure develops, is critical to slowing or reversing disease progression. Similarly, in indicated patients who have less advanced disease, CRT may be particularly beneficial.
