About this trial

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.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Age 18-80 years

Able to provide informed consent

For AR group: clinically diagnosed aortic regurgitation

For AS group: clinically diagnosed aortic stenosis

Disqualifiers

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

Trial population

Participants will be recruited from adult patients attending the cardiology department at the First Affiliated Hospital of University of Science and Technology of China, including individuals diagnosed with aortic regurgitation (AR) or aortic stenosis (AS), as well as healthy adult volunteers without known cardiovascular disease. Recruitment will focus on adults aged 18-80 years who are able to comply with finger arterial waveform measurement procedures.
