It represents an important health care issue and knowing its incidence and risk factors helps developing public and private care policies and clinical protocols. In this paper, researchers published a retrospective analysis from a tertiary hospital in Portugal regarding CHD. In this editorial, we analyze their findings and compare with other publications.
