Therefore, plaque vulnerability has been important role in the pathogenesis of acute cardiovascular events. Recent studies have reported the mechanisms responsible for plaque rupture and erosion leading to acute thrombosis in the histologic, cellular, and molecular levels. A basic approach to atherosclerotic diseases is important and helpful for physicians in clinical situation. In this article, we review related factors leading to plaque rupture and erosion in the basic aspect.
