NCT01627457

Brief Summary

In this Prestudy which will be followed by the multicentral GEx- main-trial, the feasibility of a new cardiac rehabilitation device (GEx system) is proved with coronary heart disease patients who participate in cardiac rehabilitation training exercise at the rehabilitation clinic (phase II) and subsequently at home (phase III). The GEx system consists of a easy-to-wear vest with integrated electrodes to measure electrocardiogram (ECG), respiration and activity, furthermore of a PDA to collect and store the monitored data and a cradle to charge the batteries. Several physiological parameters are extracted from thes measured vital signs like heart rate, breathing rate, ECG and activity. In this pretrial first the GEx sensor system is validated during guided exercise of the patients in the rehabilitation clinic (phase II). Subsequently at home (phase III) the practicability of the vest and sensors and possible technical problems in real- life use are proved. This means after moderate training like walking, cycling or running at home for 3 weeks patients will report the feasibility of usage. The ECG data and breathing- frequency data will be analyzed to see if data are recorded and transmitted well in regard to technical problems.

Outcome Measures

Primary Outcomes (1)

  • Evaluation of accuracy and safety of data of the GEx system received during in-patient cardiac rehabilitation (phase II) and evaluation of practicability and technical problems in real- life use during cardiac rehabilitation at home (phase III).

    The GEx system is evaluated during in-patient cardiac rehabilitation supervised by cardiologists in order to analyze data for quality of heart rate measurement and data acquisition by device. 30 Patients undergo moderate training exercise like walking, cycling or running three times a week three weeks long. In a second step practicability and technical problems are tested during continuation of the moderate training of the patient at home. The Evaluation is performed by CPX, lactate measurement, 2D-Echo, questionnaires and device data like heart rate and breathing rate.

Study Arms (1)

GEx Training

EXPERIMENTAL

CAD Patients in cardiac rehabilitation phase II (inpatient) and phase III (at home)in order to analyze data for quality of heart rate measurement and data acquisition by device as well as for practicability and technical problems at home.

Device: Guided Exercise (GEx) system

Interventions

30 CAD patients will wear the GEx system while they are trained during inpatient cardiac rehabilitation (phase II) in order to evaluate accuracy and safety of data like heart rate, breathing, ECG three times a week for about three weeks. In a second step these patients train at home (phase III) in order to evaluate practicability and technical problems of the GEx device three times a week for about three weeks.
