Cell Therapy for Refractory Angina: A Reappraisal

Figure 2

Indices of angina severity used to evaluate the effect of cardiac cell-based therapy in patients with RA. This schematic representation provides an analysis of the improvements observed in clinical trials relative to CCS class (a), CCS class greater than 2 (b), angina frequency (c), and nitroglycerine use (d). Positive and negative study outcomes have been defined according to statistical significance. The number of studies in the analysis is indicated between brackets. CCS: Canadian Cardiovascular Society; NTG: nitroglycerin.
