Cardiac Rehab Retrospective Review (CR3)
- Conditions
- Ventricular ArrythmiaVentricular FibrillationVentricular TachycardiaHeart FailureSudden Cardiac Death
- Registration Number
- NCT04675957
- Lead Sponsor
- Medical University of Graz
- Brief Summary
All patients enrolled in the Austrian LifeVest Registry will be retrospectively screened for successfully completed ambulatory or stationary rehabilitation program. Baseline characteristics, complete rehab data, outcomes and follow up data, as well as wearable cardioverter defibrillator(WCD)-derived data will be collected from these patients.
Specifically, performance data from the start of the exercise training (ET) will be compared to the end of ET; including type of training, exertion, time and duration will be collected. In addition, WCD recorded data such as automatically and manually recorded ECGs, compliance, and TRENDS data will be collected.

* BradycardiaNumber of inadequate WCD alarms (as recorded by WCD) per patient 3 months To investigate the safety and feasibility of WCD therapy during cardiac rehabilitation, the number of inadequate WCD alarms will be recorded
Number of other issues with WCD 3 months To investigate the safety and feasibility of WCD therapy during cardiac rehabilitation, every data with an issue with WCD disturbing the normal rehabilitation activities will be collected.
Number of adequate WCD alarms (as recorded by WCD) per patient 3 months To investigate the safety and feasibility of WCD therapy during cardiac rehabilitation, the number of adequate WCD alarms will be recorded
Number of patients with abnormal blood pressure (measured in mmHg) 3 months To investigate the safety and feasibility of WCD therapy during cardiac rehabilitation, the following data for abnormal blood pressure will be collected:
* Occurrence of Hypotension

Number of patients with inappropriate WCD Shocks 3 months To investigate the safety and feasibility of WCD therapy during cardiac rehabilitation, the number of inappropriate WCD shocks (captured via LifeVestNetwork) will be collected.
Number of patients with appropriate WCD Shocks 3 months To investigate the safety and feasibility of WCD therapy during cardiac rehabilitation, the number of appropriate WCD shocks will be collected.
Number of other Adverse Events 3 months To investigate the safety and feasibility of WCD therapy during cardiac rehabilitation, other adverse events recorded by staff during therapy session that stopped ET session (notWCD specific) will be collected.
- Secondary Outcome Measures
Name Time Method Performance in ergometry - measured in watts (difference between initial Evaluation and final Evaluation) 3 months The measures regarding exercise performance while wearing a WCD during cardiac rehabilitation will be evaluated through the use of descriptive statistics before and after rehabilitation.
Body weight - measured in kilogram (difference between initial Evaluation and final Evaluation) 3 months The measures regarding exercise performance while wearing a WCD during cardiac rehabilitation will be evaluated through the use of descriptive statistics before and after rehabilitation.
diastolic dysfunction (measured in grade) 3 months The measures regarding exercise performance while wearing a WCD during cardiac rehabilitation will be evaluated through the use of descriptive statistics before and after rehabilitation.
With Echocardiography, the diastolic dysfunction (grade) will be collected.Body Position derived from the WCD 3 months The correlation of WCD-derived parameters such as body position with patients' exercise performance during cardiac rehabilitation will primarily be an ad-hoc statistical analyses. Body position is measured by position sensors.
Step count derived from the WCD (steps/day) 3 months The correlation of WCD-derived parameters such as the step count with patients' exercise performance during cardiac rehabilitation will primarily be an ad-hoc statistical analyses.
Intraventricular septum (diastolic, measured in mm) 3 months The measures regarding exercise performance while wearing a WCD during cardiac rehabilitation will be evaluated through the use of descriptive statistics before and after rehabilitation.
With Echocardiography, the Intraventricular septum (diastole, mm) will be collected.Difference in physical exercise capacity - measured in METs 3 months The measures regarding exercise performance while wearing a WCD during cardiac rehabilitation will be evaluated through the use of descriptive statistics before and after rehabilitation.
Body Mass Index (BMI, weight and height will be combined to report BMI in kg/m^2); (difference between initial Evaluation and final Evaluation) 3 months The measures regarding exercise performance while wearing a WCD during cardiac rehabilitation will be evaluated through the use of descriptive statistics before and after rehabilitation.
Blood pressure - measured in mmHg (difference between initial Evaluation and final Evaluation) 3 months The measures regarding exercise performance while wearing a WCD during cardiac rehabilitation will be evaluated through the use of descriptive statistics before and after rehabilitation.
Size of the Left atrial (measured in mm) 3 months The measures regarding exercise performance while wearing a WCD during cardiac rehabilitation will be evaluated through the use of descriptive statistics before and after rehabilitation.
With Echocardiography. the size of the Left atrial (mm) will be collected.Left ventricular ejection fraction - measured in % (difference between initial Evaluation and final Evaluation) 3 months The measures regarding exercise performance while wearing a WCD during cardiac rehabilitation will be evaluated through the use of descriptive statistics before and after rehabilitation.
With echocardiography the left ventricular ejection fraction (%) will be collected.Left ventricular end diastolic diameter (measured in mm) 3 months The measures regarding exercise performance while wearing a WCD during cardiac rehabilitation will be evaluated through the use of descriptive statistics before and after rehabilitation.
