Global Longitudinal Peak Systolic Strain (GLPSS) Derived From Transesophageal Echocardiography - A Reliable Measure of Systolic Function?

An observational study of Surgery, run by Medical University of Vienna at 1 site in Austria.

Trial summary

Systolic function is a substantial determinant of overall hemodynamics and organ function. Therefore assessment of left ventricular systolic function (LVF) has been of central interest in Echocardiography. Ejection fraction (EF) measurement has been the gold standard echo-derived measure to describe LVF. Read more about this study

About this study

Official title: Is Global Longitudinal Peak Systolic Strain (GLPSS) Derived From Transesophageal Echocardiography a Reliable Measure of Systolic Function? A Multicenter-Study to Compare GLPSS With Ejection Fraction Derived From Biplane Simpson´s Method on TTE and TEE in Patients Undergoing Elective Cardiac and Non-Cardiac Surgery

Systolic function is a substantial determinant of overall hemodynamics and organ function.

Therefore assessment of left ventricular systolic function (LVF) has been of central interest in Echocardiography. Ejection fraction (EF) measurement has been the gold standard echo-derived measure to describe LVF. However, EF is a blood pool derived and therefore load dependent measure.

Global longitudinal peak systolic strain average is a new parameter derived from speckle tracking tachnique. As a primarily myocardial deformation parameter it is considered to be an equivalent to EF measurement, but maybe less load dependend. The aim of the study is to investigate the reliability of GLPSS average to quantify LVF in the perioperative setting (in cardiac and non-cardiac cases).

Questions about this trial

What is this clinical trial studying?

An observational study of Surgery, run by Medical University of Vienna at 1 site in Austria.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 8 Apr 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Austria. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Heinz D Tschernich, M.D. (+43140400 ext. 4109, heinz.tschernich@meduniwien.ac.at), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

multivariate regression-analysis (time frame: 1, 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Apr 2009.
