简要总结
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.
详细描述
The study will involve women aged 18 to 65 years, with stable anginal chest pain and no coronary artery disease (ANOCA) (absence of coronary plaque in coronary angiography or computed tomography coronary angiography - CCTA), recruited at the National Institute of Cardiology (INC). The upper age limit was established to limit the influence of vascular senescence on the results.
