Angiogenic Growth Factors for Coronary Artery Disease: Current Status and Prospects.

Although there have been advances in coronary artery bypass grafting and percutaneous coronary intervention, some patients who have ischemic coronary artery disease (CAD) are ineligible for revascularization due to suboptimal anatomy. Cardiac angiogenesis is not only a physiological response to ischemia or hypoxia but also a potential target of therapeutic strategies. Preclinical studies have shown a great enthusiasm on therapeutic angiogenesis for ischemic CAD. However, the latest trials provided the limited evidence on its efficacy. This article aims to discuss the physiological process of angiogenesis, the characteristic of angiogenic growth factors, delivery system, and clinical and preclinical studies, which can provide a novel insight into the therapeutic angiogenesis for CAD.
