Plain-language summary
Prospective, interventional, multicentre, non-randomized, single-arm open-label study that aims to enroll 200 consecutive patients with suspected chronic ischemic heart disease in the absence of obstructive coronary artery disease (INOCA) at clinically indicated coronary angiography in 3 Italian centers.
During coronary angiography, these patients will be simultaneously subjected to a functional and coronary physiology study (according to the methods reported below):
* Functional evaluation with fractional flow reserve (FFR), instantaneous wave-free ratio (iFR), Resting Full-Cycle Ratio (RFR) of angiographic stenosis\> 50%;
* In the presence of coronary angiographic stenosis \<50% or\> 50% but in the presence of a negative functional assessment (FFR\> 0.80 and iFR / RFR\> 0.90), coronary flow reserve (CFR) and index of microvascular resistance (IMR) will be measured. IMR and CFR will be assessed using intra-coronary guidance;
* In the presence of CFR\> 2.0 and IMR \<25, tests with acetylcholine will also be performed in order to evaluate the possible presence of epicardial (focal or diffuse) or microvascular spasm.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
