About this study

Official title: A Clinical Study to Determine the Correlation Between the SPhENo-Cardiograph™, a Seismocardiograph Device, and GE Vivid Q, an Echocardiograph, for Known Systemic Timing Intervals (STI).

The study Sponsor, Heart Force Medical Inc. (HFM), has developed a patented medical device called the SPhENo-CardiographTM. The SPhENo-Cardiograph™ provides a non-invasive assessment of the electro-mechanical function of the heart. The electrocardiograph (ECG) represents the waveform of the electrical stimulus to the cardiac muscle. The mechanical actions of the electrical potentials delivered in the ECG are revealed as the seismocardiograph (SCG). The SCG represents the changes in acceleration of the heart during the cardiac cycle. The SCG waveform reflects the ultra-low frequency vibrations of cardiac contraction. These low frequency vibrations are transmitted through the sternum. Using the point of initiation of ventricular contraction on the ECG, the Q wave, with fiduciary points on the synchronous seismocardiograph, it is possible to determine timing events of the cardiac cycle. The timing events of the cardiac cycle during systole are referred to as Systolic Timing Intervals (STI) and comprise the Pre-Ejection Period (PEP) and the Left Ventricular Ejection Time (LVET). The PEP is the time from the Q wave to the Aortic valve opening. The Left Ventricular Eject Time (LVET) is the time between the Aortic Valve opening and closing. The ratio of PEP/LVET in individuals with established heart disease is > 0.42. It is based on the formula described by Dr Arnold Weissler and first published in Circulation in 1968 (Weissler et al,1968). Weissler et al showed that the PEP/LVET ratio >0.42 are indicative of a lengthening of the PEP with some marginal shortening of the LVET. This is indicative of pathology associated with the coronary circulation (Ahmed et al, 1972;). This ratio can then be used as part of a non-invasive quantitative assessment of cardiac performance (Lewis et al 1977).

Using the SPhENo-CardiographTM, HFM has developed an algorithm to assess heart health that otherwise requires a number of technologies; stethoscope, ECG and Carotid pulse tracing to identify the dicrotic notch or Aortic Valve closure.

Questions about this trial

What is this clinical trial studying?

A study testing SPhENo-Cardiograph in people with Cardiovascular Risk Factor, run by Heart Force Medical Inc. at 1 site in Canada.

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 3 inclusion and 9 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: finished, as of the sponsor's last update on 11 Feb 2016. 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 Canada. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Correlation coefficient ≥0.8 between STI ratio values determined by the SPhENo-Cardiograph™ and an echocardiograph (time frame: 1 day). The study lists 4 primary outcomes in all. 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 11 Feb 2016.
