Brief Summary

AID-ANGIO is an observational, prospective, single arm, longitudinal study. Its objective is to investigate the diagnostic yield of the systematic use of a diagnostic strategy hierarchically addressing both obstructive and non-obstructive causes of myocardial ischaemia in an all-comers population of patients with chronic coronary syndromes (CCS) undergoing invasive coronary angiography (ICA). Angiographically severe-grade stenosis (≥70%) can be safely considered flow-limiting without further physiological assessment. Conversely, by means of a pressure guidewire, intermediate-grade stenosis would be evaluated with fractional flow reserve (FFR) and/or non-hyperaemic pressure ratios (NHPR) in order to determine if they are physiologically relevant. Those patients with non-obstructive CAD or normal epicardial coronary arteries would undergo functional coronary tests to investigate the presence of microcirculatory and vasomotor coronary disorders, which would account for non-obstructive causes of ischaemia. The main hypothesis of AID-ANGIO study states that, in patients with CCS referred to ICA, the application of a structured strategy -including ICA, physiological assessment of intermediate-grade stenosis and functional coronary tests- leads to a high diagnostic accuracy.

Outcome Measures

Primary Outcomes (1)

  • Number of patients with a definite diagnosis of a cause of myocardial ischemia after ICA and an AID strategy.

    To investigate the additional diagnostic value of an AID strategy over ICA alone in an all-comer population of patients with CCS.

    From date of the first inclusion in the study until the date of last inclusion, assessed up to 48 months.

Secondary Outcomes (2)

  • Number of patients in which the application of an AID strategy leads to a change from the initial treatment plan, only based in clinical information and ICA findings.

    From date of the first inclusion in the study until the date of last inclusion, assessed up to 48 months.

  • Number of patients with CMD, defined as low CFR or high IMR.

    From date of the first inclusion in the study until the date of last inclusion, assessed up to 48 months.

Study Arms (1)

Single arm

There is only one arm. Initially, a tentative diagnosis would be performed by the clinician, only taking into account patients's clinical information and angiography images. After applying AID strategy, a final diagnosis will be reached and compared with the tentative one.

Diagnostic Test: AID strategy

Interventions

AID strategyDIAGNOSTIC_TEST

AID strategy encompasses a hierarchical algorithm intended to investigate both obstructive and non-obstructive causes of myocardial ischaemia. AID strategy starts with an ICA. Angiographically severe-grade stenosis (≥70%) can be safely considered flow-limiting without further physiological assessment. Conversely, by means of a pressure guidewire, intermediate-grade stenosis should be evaluated with FFR and/or NHPR in order to determine if they are physiologically significant. Those patients with non-obstructive CAD or normal epicardial coronary arteries should undergo functional coronary tests to investigate the presence of microcirculatory and vasomotor coronary disorders, which would account for non-obstructive causes of ischaemia.

Sampling MethodNon-Probability Sample
Study Population

All-comer study population of patients with CCS referred to ICA.

You may qualify if:
