  • For healthy controls: no history of cardiovascular disease
  • Able to undergo finger arterial waveform measurement

Who cannot join

  • History of recent cardiac surgery or intervention (<6 months)
  • Hand disorders affecting finger mobility (e.g., arthritis)
  • Pregnant or breastfeeding women
  • Participation in other studies affecting arterial waveform
  • Unable to understand or comply with study procedures

About this study

Official title: A Study on Noninvasive Real-Time Arterial Pressure Waveform Analysis for the Detection and Evaluation of Cardiovascular Diseases

The goal of this observational study is to learn whether noninvasive real-time arterial waveform monitoring can be used to assess cardiovascular diseases in adults. The main question it aims to answer is:

Can photoacoustic imaging accurately capture arterial waveforms from patients' fingers? Can features extracted from the arterial waveforms reflect the type and severity of cardiovascular diseases? Participants will be asked to place their fingers into the imaging device, where their finger arterial pulse information will be noninvasively recorded.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT07350629
Study groupRoleWhat they receive
Healthy SubjectsHealthy adult volunteers with no known cardiovascular disease will undergo noninvasive arterial waveform acquisition using the photoacoustic imaging device. No intervention is applied; data collection provides baseline waveform features for comparison with AR and AS patients.
Aortic Regurgitation (AR) PatientsParticipants diagnosed with aortic regurgitation (AR) will undergo noninvasive arterial waveform acquisition using a photoacoustic imaging device. No intervention is applied; data collection focuses on capturing finger arterial pulse waveforms to assess features associated with AR.
Aortic Stenosis (AS) PatientsParticipants diagnosed with aortic stenosis (AS) will undergo noninvasive arterial waveform acquisition using the same photoacoustic imaging device. No intervention is applied; data collection focuses on capturing finger arterial pulse waveforms to assess features associated with AS.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluation of the state of aortic regurgitation and aortic stenosis by photoacoustic tomography

    To determine the feasibility of using photoacoustic tomography to differentiate aortic regurgitation and aortic stenosis based on arterial waveform measurements.

    Measured: At enrollment (single time point)

Secondary outcomes (3)
  1. Rise time of photoaocustic arterial waveform

    To determine the systolic upstroke rise time of arterial waveforms using photoacoustic tomography

    Measured: At enrollment (single time point)

  2. Decay time of photoaocustic arterial waveform

    To determine the diastolic decay time of arterial waveforms using photoacoustic tomography

    Measured: At enrollment (single time point)

  3. Dicrotic notch time of photoaocustic arterial waveform

    To determine the dicrotic notch time of arterial waveforms using photoacoustic tomography

    Measured: At enrollment (single time point)

Questions about this trial

What is this clinical trial studying?

An observational study of Aortic Regurgitation Disease and Aortic Stenosis Disease, run by Anhui Provincial Cancer Hospital at 1 site in China.

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 6 inclusion and 5 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: looking for participants now, as of the sponsor's last update on 20 Jan 2026. 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 China. 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?

This study is still under way. Results are not available in the source record yet.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluation of the state of aortic regurgitation and aortic stenosis by photoacoustic tomography (time frame: At enrollment (single time point)). 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 20 Jan 2026.
