简要总结
To characterize the physiological signals collected from a Wearable Cardiac Monitor (WCM) prototype device in subjects with heart failure and preserved ejection fraction (HFpEF) and compare against signals from subjects with heart failure and reduced ejection fraction (HFrEF).
To evaluate the relationship of physiological signals measured from a wearable cardiac monitor (WCM) prototype device with ECHO measures of systolic and diastolic function
详细描述
This is a non-randomized, feasibility study that will enroll up to 100 participants clinically diagnosed with HFpEF or HFrEF. Approximately 70% of participants will have HFpEF and 30% will have HFrEF.
There will be one study visit per participant. The study visit includes device placement and data collection during postural changes. Echocardiograms will also be collected throughout the study and at least 30% of participants will undergo a submaximal exercise test. The device will then be removed.

入选标准
- •Patients with NYHA class II or III heart failure defined by symptoms and signs of heart failure
- •Documented episode of decompensated heart failure in the past 3 years, which either: a) resulted in a hospital admission (primary diagnosis) or b) was treated in out-patient clinic
- •HFrEF defined by documented evidence of EF ≤ 40% OR
- •HFpEF defined by documented evidence of:
- •EF ≥ 50% and no prior record of EF < 40%
