The National Heart, Lung, and Blood Institute (NHLBI) awarded a $173,352 Project Grant (CFDA 93.837 - Cardiovascular Diseases Research) to Vanderbilt University Medical Center (VUMC) to conduct research on molecular characterization of frailty and functional limitations in heart failure with preserved ejection fraction (HFpEF). The key products and services to be delivered under this 5-year award, which began on Jul 15, 2025, include:

  1. Measuring associations between the human proteome and hemodynamic/physiologic measures of multi-organ function in HFpEF patients.
  2. Identifying and prioritizing reversible pathways of multi-organ system impairment in HFpEF by measuring circulating proteomes before and after a randomized clinical trial intervention.
  3. Conducting a pilot prospective study of home-based rehabilitation using a mobile app in HFpEF patients, supported by a larger NIH-funded effort.

This research aims to elucidate the molecular mechanisms underlying frailty and functional limitations in HFpEF, a prevalent cardiovascular condition, in order to inform future targeted therapeutic approaches.
