Disclosed are a method for diagnosing a vascular disease and an apparatus therefor. A vascular disease diagnosing method according to an exemplary embodiment of the present disclosure includes: an information acquiring step of acquiring patient information for a diagnosis subject; an FFR processing step of applying a geometric feature parameter information generated based on the patient information to a first learning model to calculate fractional flow reserve (FFR) information; a CFD processing step of applying the geometric feature parameter information to computational fluid dynamics (CFD) to calculate flow feature information; and a diagnosing step of determining a vascular disease based on the fractional flow reserve information and the flow feature information and determine whether to perform a surgery on the vascular disease.
