Abstract

Heart failure (HF) occurs across the entire range of left ventricular (LV) ejection fractions (EF), not just reduced EF. Nearly half or more patients presenting with HF have a preserved EF>0.50 (HFpEF). Diastolic dysfunction is apparent in all patients with HF, regardless of EF. A preserved EF indicates that the end-diastolic volume is appropriate for the stroke volume, and a reduced EF indicates that the end-diastolic volume is enlarged relative to stroke volume (i.e. the LV is dilated). Most therapies proven to be effective in HF with a reduced EF (ACE-inhibitors, angiotensin receptor blockers, beta-blockers, and cardiac resynchronization) reverse LV dilation. These therapies have not been proven to be effective in HFpEF. Increasing c-GMP may be a treatment target in HFpEF, and potential ways of increasing c-GMP are being studied. Finally, comorbidities are important in HFpEF and are additional targets for therapy.
