Quantitative assessment of the coronary microvasculature: new tools for the black box.
E picardial coronary arteries are called conductance arteries 1 (or macrocirculation) because their normal intrinsic resistance is close to zero 2 and their main function is to transport blood. They are visible at invasive coronary angiography with an unsurpassed spatial and temporal resolution. Coronary arteries <500 µm are usually referred to as resistance arteries (or microvasculature) becau...

However, evidence that directly implicates microvascula...
متن کاملCoronary CT Angiography in the Quantitative Assessment of Coronary Plaques
Coronary computed tomography angiography (CCTA) has been recently evaluated for its ability to assess coronary plaque characteristics, including plaque composition. Identification of the relationship between plaque composition by CCTA and patient clinical presentations may provide insight into the pathophysiology of coronary artery plaque, thus assisting identification of vulnerable plaques whi...
