Vascular Endothelial Inflammation and Health Status In INOCA (VISION-INOCA)

2026年5月8日 更新者：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.

设计细节

队列和干预

团体/队列
干预/治疗
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.
程序：Invasive coronary angiography
Participant will undergo invasive coronary angiography as clinically indicated (standard of care).
程序：Coronary Artery Endothelial Cell Sampling
Endothelial cells will be obtained from clinical coronary guidewires after retrieval from the guide catheter.
设备：Fitbit
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.
诊断测试：Invasive coronary function testing
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.
程序：Invasive coronary angiography
Participant will undergo invasive coronary angiography as clinically indicated (standard of care).
程序：Coronary Artery Endothelial Cell Sampling
Endothelial cells will be obtained from clinical coronary guidewires after retrieval from the guide catheter.

研究衡量的是什么？

主要结果指标

结果测量
措施说明
大体时间
Change in Seattle Angina Questionnaire (SAQ) score
大体时间：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
大体时间：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.
Baseline, 1 year follow up

IPD 计划说明

The de-identified participant data from the final research dataset will be shared upon reasonable request beginning 9 to 36 months after publication or as required by a condition of awards or supporting agreements, provided the requesting investigator executes a data use agreement with NYU Langone Health. This instance of data sharing will also require separate IRB review as well as review from NYU Langone's Data Sharing Strategy Board (DSSB). Requests should be directed to nathaniel.smilowitz@nyulangone.org. To gain access, data requestors will need to sign a data access agreement.

IPD 共享时间框架

Beginning 9 months and ending 36 months following article publication or as required by a condition of awards and agreements supporting the research.

IPD 共享访问标准

The investigator who proposed to use the data will be granted access upon reasonable request. Requests should be directed to nathaniel.smilowitz@nyulangone.org. To gain access, data requestors will need to sign a data access agreement. This instance of data sharing will also require separate IRB review as well as review from NYU Langone's DSSB. Study data will also be submitted to publicly available databases. NHLBI BioData Catalyst (BDC) will provide long-term access to de-identified dataset(s). RNA sequencing data will be deposited into the NCBI Gene Expression Omnibus (GEO) database, a public functional genomics data repository. Data will be made available at the time of associated publication, as per NIH policy.
