The main objective is to prospectively validate the capacity of continuous thermodilution coronary flow reserve (CFRflow) as a predictor of the presence of angina measured by SAQ7 in patients with INOCA at 3 months. Secondary objectives include identifying hemodynamic factors related to the persistence of angina at 3 and 12 months, identifying clinical factors associated with the persistence of angina, establishing the prevalence of patients with coronary microvascular dysfunction within the cohort of INOCA patients, identifying predictors of major cardiovascular events at 12 months, validating the pathological value of MMR and establishing the pathological value of AF measured in ml/min. The study also aims to evaluate the concordance between measures of the coronary microvascular function obtained by continuous thermodilution and bolus thermodilution, as well as their concordance with clinical characteristics.
