  • 2. Ongoing stable GDMT HF management and management of potential comorbidities according to the 2013 ACCF/AHA Guidelines for the management of Heart Failure (with no significant changes [>100% increase or 50% decrease], excluding diuretic dose changes for a minimum of 4 weeks prior to screening) that is expected to be maintained without change for 6 months.

  • a. End-expiratory PCWP during supine ergometer exercise >= 25mm Hg, and greater than RAP by >= 5 mm Hg.
  • 6. Site determined echocardiographic evidence of diastolic dysfunction documented by one or more of the following:
  • a. LA diameter > 4 cm; or
  • b. LA volume index > 28 ml/m2 or
  • c. Lateral e* <10 cm/s; or
  • d. Septal e* <8 cm/s; or
  • e. Lateral E/e* >10 ; or
