Conclusions: Quality ACS Care Clinicians need to rapidly assess pt risk Risk factors + markers Pts at highest risk tend to benefit from most aggressive interventions However, current ACS care demonstrates: Wide variability between leading and lagging centers Paradoxical care Given tight links between care and outcome We need to work together develop successful ACS quality improvement efforts Clinicians need to rapidly assess pt risk Risk factors + markers Pts at highest risk tend to benefit from most aggressive interventions However, current ACS care demonstrates: Wide variability between leading and lagging centers Paradoxical care Given tight links between care and outcome We need to work together develop successful ACS quality improvement efforts
