Developing a Non-invasive Cardiac Functional Health Status Measurement Device

9. februar 2016 opdateret af: University of Florida

Developing a Non-invasive Cardiac Functional Health Status Measurement Device to be Used in a Critical Population of Adults and Children With Heart Failure.

This is a single-center, non-randomized study.Enrolled patients will be placed on a tilt table and a stress test will be performed in a total of 4 different positions. Their blood pressure will be measured at each position. Also, a pulse oximeter will be placed on the forehead to measure pulse rate and strength. These results will be compared to cardiac functional classifications defined by New York Heart Association (NYHA) criteria for adults and New York Pediatric Heart Failure (NYPHF) index for our pediatric age patients. The primary aim of this initiative is to assess the discriminatory value of a cardiac functional health classification based upon the degree of dependency of cardiac function on changes in cardiac preload and afterload circulatory volume.

Detaljeret beskrivelse

Participants will be asked to review the informed consent and consent to the study prior to any study procedures. The study will consist of a single visit to the Medical Plaza at the University of Florida. During this visit, Enrolled patients will be placed on a tilt table and their position changed to a total of 4 different positions. Their blood pressure will be measured at each position. Also, a pulse oximeter will be placed on the forehead to measure pulse rate and strength. The study will take approximately 25 minutes. Data collected shall include a questionnaire for the patient, a list of the patient's co-morbidities, an echocardiogram or catheter lab data if available, and a list of the patient's current medications.

Intervention / Behandling
Eksperimentel: CVInsight (TM)
Patient will be placed on a tilt table and pulse oximetry (Nonin Medical)and blood pressure will be measured at different table positions (different angles). A hemodynamic monitor called CVInsight(TM) will be used to monitor the pulse oximeter readings.
Enhed: CVInsight(TM)
Patient will be placed on a tilt table and pulse oximetry (Nonin Medical) and blood pressure will be measured at different table positions (different angles). Four positions will be explored. A hemodynamic monitor called CVInsight(TM) will be used to monitor the pulse oximeter readings.

Tidsramme
Pulse Rate
Tidsramme: Average pulse rate from baseline to 30 minutes
Continuous change of pulse rate from baseline through the end of the study will be followed. Changes in pulse rate will be plotted against the four tilt table positions. Four positions will be explored, Mounting position, baseline, passive leg raise (cardiac preload dependent) and orthostasis head raise (cardiac afterload dependent). Patients go from mounting position, to baseline, to the corresponding position (passive leg raise or orthostasis head raise) and back to baseline. The assessment will take 30 minutes. From the graph, average pulse rate is calculated.
Average pulse rate from baseline to 30 minutes
Pulse Strength
Tidsramme: Average pulse strength from baseline to 30 minutes
Continuous change of pulse strength from baseline through the end of the study. Pulse strength is measured as volts by the system. Changes in pulse strength will be plotted against the four tilt table positions. Four positions will be explored, Mounting position, baseline, passive leg raise (cardiac preload dependent) and orthostasis head raise (cardiac afterload dependent). Patients go from mounting position, to baseline, to the corresponding position (passive leg raise or orthostasis head raise) and back to baseline. The assessment will take 30 minutes. Cardiac function curves will be constructed with the data collected and average pulse strength from baseline to 30 minutes will be reported.
