Study summary

The present study has the following objectives:

1. To investigate the prevalence of INOCA in patients referring for a clinically indicated coronary angiography (CA) c/o Division of Cardiology - Federico II University Hospital;
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;
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 5 year follow up

Inclusion Criteria: * Clinical presentation of chronic ischemic heart dis- ease (IHD), requiring coronary angiography for the diagnosis; * Absence of obstructive coronary artery disease (CAD) at coronary angiography; * Age \> 18 years. * Ability to provide a valid informed consent to the study procedure at the time of baseline evaluation; Exclusion Criteria: Clinical presentation of acute coronary syndrome (ACS) or cardiogenic shock; * Presence of obstructive CAD with at least 1 significant coronary artery stenosis, defined as diameterstenosis \>50% and FFR ≤0.80 (or iFR/RFR ≤0.89); * Previous coronary artery bypass grafting (CABG); * Left ventricular systolic dysfunction, defined as ejection fraction (EF) \<40%; * Severe valvular heart disease; * Pregnant or breastfeeding women * Known hypersensitivity or contraindication to any of the drugs used for coronary physiology testing (adenosine, nitrates, acetylcholine) * Inability or unwillingness to provide a valid in- formed consent to the study procedure at the time of baseline evaluation.

Primary outcome measure(s)

  • MACE — 12 and 60 months
    Occurrence of Cardiovascular death, Myocardial infarction, Coronary revascularization
  • Degree of Angina — 12 and 60 months
    The degree of angina will be assessed using The Seattle Angina Questionnaire - 7 (SAQ-7) contains 7 questions used to measure health status in patients with coronary artery disease (CAD). The score is generated for each domain and it is scaled from 0 to 100, with 0 denoting the worst and 100 the best possible status.
  • QoL — 12 and 60 months
    Quality of life will be assessed using the 5-level EuroQoL 5-dimensions Questionnaire (EQ-5D-5L). The EQ-5D-5L descriptive system comprises the same five dimensions as the EQ-5D-3L (MOBILITY, SELF-CARE, USUAL ACTIVITIES, PAIN/DISCOMFORT and ANXIETY / DEPRESSION), but each dimension has five response levels: no problems, slight problems, moderate problems, severe problems, unable to/extreme problems. The respondent is asked to indicate his/her health state by checking the box next to the most appropriate response level for each of the five dimensions. Responses are coded as single-digit numbers expressing the severity level selected in each dimension. An EQ-5D health state is deemed to be 'better' than another if it is better on at least one dimension and is no worse in any other dimension. An EQ-5D health state is deemed to be 'worse' than another if it is worse in at least one dimension and is no better in any other dimension.
