Refractory angina as a result of chronic myocardial ischemia is a common and disabling condition. Adult progenitor cells have emerged as a potential revolutionary treatment for cardiovascular disease. Locally administered adult progenitor cells with particular vasculogenic potential may offer treatment hope for those with chronic ischemia; however, the optimal cell type, dose, delivery mode, and target patient population has not been defined. Preclinical cell therapy studies have shown safety and efficacy sufficient to warrant human trials. Early, small-scale human trials exploring various cell types and delivery modes have shown that most approaches are safe, with modest early efficacy. This overview discusses the rationale and early results for ongoing larger cardiovascular disease trials, with a special emphasis on refractory angina and chronic myocardial ischemia.
