Vascular Endothelial Inflammation and Health Status In INOCA (VISION-INOCA)
8 maj 2026 uppdaterad av: NYU Langone Health
A Single Center Diagnostic Study of Endothelial Inflammation and Health Status in Patients With Ischemia and Nonobstructive Coronary Arteries (INOCA)
The purpose of this study is to evaluate coronary artery and peripheral vein vascular endothelial profiles in patients with ischemia with non-obstructive coronary arteries (INOCA) who undergo coronary function testing (CFT).
The aims are: (1) Evaluate coronary artery endothelial profiles and associations with coronary microvascular dysfunction (CMD) in INOCA.
(2) Assess brachial vein endothelial cell profiles in patients with INOCA and associations with CMD, and (3) Characterize relationships between endothelial signatures and anginal symptoms, functional status, and physical activity at baseline and 1-year follow-up.

Grupp / Kohort |
Intervention / Behandling |
|---|---|
|
Non-Obstructive CAD
Participants with ischemia with non-obstructive coronary arteries (INOCA) and endothelial sampling will be fully eligible for long-term follow up.
A Wearable activity monitoring device (Fitbit) will be provided post-procedure to these participants.
Participants will be followed for a minimum of 1 year.
|
Participant will undergo invasive coronary angiography as clinically indicated (standard of care).
Endothelial cells will be obtained from clinical coronary guidewires after retrieval from the guide catheter.
Wearable activity monitoring device that measures physical activity based on the number of steps per day.
The device also tracks sleep efficiency (exploratory) through a proprietary algorithm, and other health metrics.
Daily step count and heart rate are recorded on the wearable device.
Participants will undergo invasive coronary function testing as clinically indicated (standard of care).
|
|
Obstructive CAD
Participants with obstructive coronary artery disease (CAD) at the time of angiography may undergo endothelial sampling and blood collection but will not be provided a wearable activity monitoring device or undergo long-term follow up.
|
Participant will undergo invasive coronary angiography as clinically indicated (standard of care).
Endothelial cells will be obtained from clinical coronary guidewires after retrieval from the guide catheter.

Åtgärdsbeskrivning |
Tidsram |
|---|---|---|

Change in Seattle Angina Questionnaire (SAQ) score
Tidsram: Baseline, 1 year follow up
|
The Seattle Angina Questionnaire (SAQ) scores range from 0 to 100 for all five domains (Physical Limitations, Angina Stability, Angina Frequency, Treatment Satisfaction, and Quality of Life), with higher scores indicating better health status, fewer limitations, and less frequent angina.
A 10-point change in score is typically considered clinically significant.
|
Baseline, 1 year follow up
|
|
Change in Duke Activity Status Index (DASI) score
Tidsram: Baseline, 1 year follow up
|
The DASI is a 12-item self-report questionnaire used to assess a patient's functional capacity.
Scores range from 0 to 58.2, with higher scores indicating better functional capacity.
