Angiographic segment size in patients referred for coronary intervention is influenced by constitutional, anatomical, and clinical features.

Background: Factors influencing the size of target vessels of patients referred for coronary intervention are poorly defined. We aimed to investigate in a large series of patients undergoing percutaneous intervention the relation of constitutional, anatomical, and clinical features with the reference diameter of coronary vessels treated with stenting.

Methods: A total of 4,850 de novo coronary lesions, non-ostial and non-bifurcational, located in native vessels were analyzed.
