The primary objective of this project is to validate a multi-modal systemic microvascular phenotyping platform-combining Laser Speckle Contrast Imaging (LSCI) and Sublingual Handheld Videomicroscopy (IDF imaging)-as a non-invasive surrogate for coronary microvascular function in women with ANOCA (Angina with Non-Obstructive Coronary Arteries). We aim to demonstrate that systemic microvascular signatures (microvascular reactivity and density) can predict coronary endotypes with high accuracy, potentially reducing the need for invasive diagnostics.

Evaluation of endothelium-dependent skin microvascular reactivity.
Timeframe: Microvascular reactivity will be evaluated 20-minute rest in the supine position in a temperature-controlled room.
