The Effect of Physical Therapy Intervention in Patients With Left Ventricular Assistive Device on Physical Function

Study Overview
=================
Brief Summary
-----------------
To retrospectively investigate the effect of physical therapy intervention on improving physical function of patients post left ventricular assist device (LVAD) through electronic medical record survey

Detailed Description
-----------------
Method: Using portable electronic medical record system in National Taiwan University Hospital (NTUH), retrospectively survey medical record of patients who underwent left ventricular assist device (LVAD) operation in NTUH, compare improvement among those who had received physical therapy intervention and those who hadn't. Inclusion criteria: aged older than 20 years old; diagnosed with heart failure and need LVAD implantation Progress: Note down patients' clinical signs and symptoms, drug usage, imaging findings, physical therapy intervention details, and recovery of functional status. Physical therapy intervention details include: onset symptoms, history, treatment frequency, treatment type, any signs and symptoms during treatment progress and recovery of functional status post physical therapy.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in walking function | By using Six-Minute Walk Test (6MWT), we can obtain the maximum distance that patient can afford walking. In 6 minutes, they should walk as many as they can, on a 15-meter level corridor, assisted device (e.g. cane) can be used if they need. During the test, the patient can stop or rest if they want. | Baseline, two weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Rating Perceived Exertion (RPE) | By using the Borg Rating of Perceived Exertion Scale (score 6-20), the patient subjectively grade the level of perceived exertion after 6MWT. | Baseline, two weeks | 
| Change in heart rate | While doing 6MWT, patients' heart rate will be monitored through portable electrocardiography (ECG) throughout the test. Resting heart rate and heart rate after 6MWT will be recorded. | Baseline, two weeks | 
| Change in blood pressure | Resting blood pressure and blood pressure after 6MWT will be measured. | Baseline, two weeks |
