Beyond GDMT: bridging the therapeutic gap in heart failure.

Guideline-directed medical therapy is the backbone of heart failure treatment. However, patients continue to experience heart failure symptoms, impaired quality of life, and reduced functional status despite guideline-directed medical and device treatment. There is a void in treatment alternatives between guideline-directed therapy and the advanced heart failure surgical options of heart transplant (HT) and left ventricular assist device (LVAD). Cardiac contractility modulation and baroreceptor activation therapies are shown to improve heart failure symptoms, quality of life, and exertional capacity in select patients and complement our current treatment paradigm. The purpose of this paper is to review these novel Food and Drug Administration (FDA)-approved heart failure therapies and facilitate the identification of appropriate candidates.
