Clinical Trial Substantiates Superiority of SRAclinic in the Detection of Atrial fibrillation
- The international medical journal 'Stroke' published convincing results of a clinical trial conducted at the University Hospital Heidelberg, Germany
- SRAclinic shows significant superiority over standard procedures - 40 percent more patients with paroxysmal atrial fibrillation identified
Throughout Germany, in France and Austria, more than 30 hospitals (stroke units) already use successfully the fully automated ECG analysis for the detection of atrial fibrillation SRAclinic (SRA = Stroke Risk Analysis), developed by the apoplex medical technologies GmbH, Pirmasens (Germany). The medical journal "Stroke", an official journal of the American Heart Association, just published the results of a clinical trial, which proves a clear superiority of SRAclinic* to the current standard procedures for the detection of paroxysmal atrial fibrillation. This is of great importance especially for those patients with strokes of unknown origin. Only the detection of atrial fibrillation makes an adequate therapy with anticoagulating drugs possible to reduce the risk for further strokes.
The publication in "Stroke" is based on a prospective study conducted by the principal investigator Prof. Dr. med. Roland Veltkamp, between March 2010 and January 2011 on approximately 500 patients at the stroke unit of the University Hospital Heidelberg. The study compared the detection rate of paroxysmal atrial fibrillation of SRAclinic with the current standard procedure. The investigators succeeded in proofing superiority of SRAclinic over the 24 hour long term ECG and the ECG monitoring without the automated detection software in the identification of patients with paroxysmal atrial fibrillation.
"SRAclinic has clearly proven it's superiority over the elaborate methods used in our stroke unit to detect atrial fibrillation", states Prof. Dr. med. Roland Veltkamp. "After the analysis of the study results we changed the routine diagnostic for the detection of paroxysmal atrial fibrillation at our stroke unit with 20 beds completely to SRAclinic. The anyway recorded ECG signals from the monitoring system at the stroke unit are analysed by SRAclinic. 24 hour long term ECGs are only recorded in exceptional cases which means a considerable relieve for our colleagues from cardiology."

"SRAclinic is well on the way to become the standard procedure for the detection of paroxysmal atrial fibrillation in stroke units. In about 25 percent of all strokes in Germany the origin of the stroke cannot be identified. A substantial part of these is assumed to be caused by undetected paroxysmal atrial fibrillation, which increases the risk for secondary strokes with worse consequences for the patients" states Albert Hirtz, Managing Director of apoplex medical technologies GmbH. "New methods do not necessarily induce higher costs but can often reduce the current costs - with benefits for the patients and the insurance companies. SRAclinic is safe, reliable and a resource-efficient solution, as it uses data from the monitoring system for the analysis" emphasizes Albert Hirtz the economical advantages of SRAclinic.
Convincing Study Results
The objective of the study was a comparison of the two presently applied standard procedures in stroke units, which are 24 hour long term ECG and patient monitoring, with SRAclinic in relation to an identification of patients with previously unknown paroxysmal atrial fibrillation. Patients with ischemic stroke or TIA (transitional ischemic attack) were included in the study. During their stay at the stroke unit, in 41 from 496 patients paroxysmal atrial fibrillation was detected for the first time. 14 (34.1%) patients were found with 24 ECG recordings, 27 (65.9%) with the continuous bed side electrographic monitoring and 38 (92.7%) have been identified with SRAclinic. That means, SRAclinic is able to increase the detection rate for paroxysmal atrial fibrillation more than twofold compared to the widely used 24 hour long term ECG recording.
Background information to SRAclinic
The fully automated Stroke Risk Analysis SRAclinic, developed by the apoplex medical technologies GmbH, Pirmasens, for the detection of atrial fibrillation is already used in the stroke units of more than 30 hospitals in Germany, France and Austria.
SRAclinic is analysing the ECG data from the mandatory patient monitoring or from long term ECG recordings. The analysis is based on a mathematical algorithm which interprets deviations from the heart rate dynamics which come along with atrial fibrillation. There is also a version for primary prevention (SRAdoc und SRA24), which is offered to General practitioners.
