About this study

This is a prospective pilot study to evaluate changes before and 4 weeks(+/- 1 week) after beta-blocker withdrawal in 30 HFpEF patients. The study involves 2 visits that are 4 weeks apart. The first study visit will occur at a standard of care clinic visit and the second visit will be a research visit to fill out questionnaires and perform the limited echocardiogram. No long term follow up beyond the 2nd visit.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Stable HFpEF patients with NYHA Class II-III or elevated BNP ≥100
  • N=30 (Target: 30).
  • Age: 50 ~ 80 years.
  • ECHO evidence of EF ≥50% and Grade 2 or 3 diastolic dysfunction.
  • Chronic loop diuretic use
  • Currently on beta-blocker

Exclusion criteria

  • Beta blocker was prescribed for treating other cardiac conditions such as atrial fibrillation or coronary artery disease.
  • Heart rate > 100 bpm
  • Recent hospitalization due to HF within 3 months
  • Non-English speaker

Primary outcomes

  1. Changes in KCCQ-23 score

    Time frame: Baseline and after 4 weeks of beta blocker discontinuation

    Kansa city cardiomyopathy questionnaire (KCCQ-23)- self-administered, 23-item. questionnaire that quantifies physical limitations, symptoms, self-efficacy, social interference and quality of life. Scores are transformed to a range of 0-100, where higher scores reflect better health status.

Secondary outcomes

  1. Changes in cardiac mechanics by echocardiography

    Time frame: Baseline and after 4 weeks of beta blocker discontinuation

    Echocardiographic E/e' ratio

  2. Changes in biomarker

    Time frame: Baseline and after 4 weeks of beta blocker discontinuation

    changes from baseline in BNP level (pg/mL) after 4 weeks of beta blocker discontinuation

  3. 6 minute walk test

    Time frame: Baseline and after 4 weeks of beta blocker discontinuation

    The distance (meters) covered over a time of 6 minutes. A greater distance indicates a better exercise capacity.
