NCT05164640

Brief 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.

Outcome Measures

Primary Outcomes (3)

  • investigate the prevalence of INOCA in women vs. men

    1\. To investigate the prevalence of INOCA in women vs. men who are referred for a clinically indicated coronary angiography in three Centers in North-ern, Central and Southern Italy;

    3 year

  • stratify in INOCA endotypes patients

    2\. to stratify in INOCA endotypes patients according to the presence or absence of alternative (i.e. non obstructive CAD) causes of myocardial ischemia detected during CA clinically indicated through physiology tests

    1 day (during physiology tests)

  • implement a stratified therapy

    3\. to implement a stratified therapy in these patients considering the different INOCA endotypes and evaluate the impact on angina class and quality of life as well as cardiac hospitalization and coronary revascularization during 1 year follow up

    1 year

Study Arms (1)

assessment of coronary physiology

OTHER

This is a prospective, multicentric, non-randomized , single-arm , open label clinical study. Included patients will be studied with invasive functional tests performed during index coronary angiography. These will include FFR, instantaneous Wave-Free Ratio (iFR), Resting Ful-Cycle Ra-tio (RFR), CFR, IMR and provocative Acetylcholine test. After the diagnosis of vasospastic angina (VSA) or coronary microvascular dysfunction (CMD) is made, a stratified medical therapy will then be initiated according to the results of physiological assessment according to ESC guidelines and recent EAPCI expert consensus document .

Other: not required

Interventions

This a multicenter, prospective, non-randomized, single-arm, open label clinical study. This design doesn't include control vs intervention arms
