The goal of this prospective study is to assess the correlation between coronary microvascular disfunction and insulin resistance in patients with INOCA.
Patients with ANOCA and without diabetes will undergo invasive coronary microvascular assessment through coronary angiography and insulin resistance assessment through hyperinsulinemic-euglycemic clamp test.
Patients enrolled in the study will be followed for a period of 2 years to monitor their clinical status.
