Novel Wearable Device for Heart Failure Management

Study Overview
=================
Brief Summary
-----------------
Heart failure (HF) is a major cardiovascular disease with high readmission and mortality rate. A wearable device that could remotely monitor and detect the worsening HF early before the symptoms appear will help reduce HF readmissions effectively. The purpose of the current study is to examine the efficiency of a novel wearable device based on flexible strain sensor comparing to the clinical 'gold standard,' and then transform it into a clinical application.

Detailed Description
-----------------
The prospective cohort study aims to examine the efficiency of a novel wearable device based on a flexible strain sensor to improve the outcomes of patients with HF compared to the standard-of-care without wearable device monitoring. The primary and secondary endpoints will be examined in subgroups determined by baseline variables reflecting demography,NYHA functional class,left ventricular ejection fraction,natriuretic peptide,additional co-morbidities,and others.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Rate of Hospital Readmissions for Heart Failure | Total hospitalizations for heart failure will be monitored via follow-up. | Up to 6 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Concordance of the Jugular Vein Pressure with the RHC Measurement | Accuracy of jugular vein pressure measurements by the novel wearable device compared to right heart catheterization. | Up to 6 months | 
| Change From Baseline N-terminal Pro-brain Natriuretic Peptide(NT-proBNP) or Brain Natriuretic Peptide(BNP) | Change from baseline to 6 months in N-terminal pro-brain natriuretic peptide (NT-proBNP) or Brain Natriuretic Peptide(BNP). NT-proBNP/BNP level will be measured using commercial kits system during the follow-up period. Change from baseline was defined as the value of NT-proBNP/BNP at 6 months minus the baseline value. Baseline value was defined as the mean of all available measurements from the screening visit. | Up to 6 months | 
| Change in Exercise Capacity as Measured by the 6-Minutes-Walking-Test (6MWT) Distance. | Change from baseline to 6 months in exercise capacity as measured by the distance walked in 6 minutes in standardised conditions. | Up to 6 months | 
| Compliance Percentage of Patients | Patient adherence to daily measurement and transmission of sensor readings will be recorded. | Up to 6 months | 
| Change in Quality of Life | Quality of life will be measured with the Kansas City Cardiomyopathy Questionnaire (KCCQ) answered by the patients directly on a patient application.KCCQ is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. The KCCQ total symptom score incorporates the symptom domains into a single score. Scores are transformed to a range of 0-100, in which higher scores reflect better health status. | Up to 6 months | 
| Change in New York Heart Association (NYHA) functional class. | NYHA class will be evaluated according to the patients' clinical characteristics during the follow-up.NYHA Functional Classification places patients in one of four categories based on how much they are limited during physical activity; Class I being best and Class IV being the worst functional class. Class I has no limitation to physical activity, Class II has slight limitation to physical activity, Class III has marked limitation of physical activity, and Class IV is unable to carry out any physical activity without severe discomfort. | Up to 6 months | 
| Freedom From a Device/System-related Complication | Device/System-related Complications refer to adverse events such as device failure and allergy. | Up to 6 months |
