The goal of this observational study is to explore the incidence and effect on prognosis of coronary microvascular dysfunction in patients present of stable anginal symptoms, a clinical indication for invasive coronary angiography, and no hemodynamically significant epicardial coronary artery disease, defined as fractional flow reserve (FFR) \>0.80.
