Multicenter Study Comparative Study Observational Study
Comparison of various scores for predicting success of chronic total occlusion percutaneous coronary intervention.
Various scoring systems have been developed to predict the technical outcome and procedural efficiency of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). ⋯ CL, J-CTO and PROGRESS CTO scores perform moderately in predicting technical outcome of CTO PCI, with better performance for antegrade-only procedures. All scores correlate with procedure time and fluoroscopy dose, and the CL score also correlates with contrast utilization.

Impact of door-to-balloon time on long-term mortality in high- and low-risk patients with ST-elevation myocardial infarction.
Door-to-balloon time (DTBT) less than 90min remains the benchmark of timely reperfusion in ST-elevation myocardial infarction (STEMI). The relative long-term benefit of timely reperfusion in STEMI patients with differing risk profiles is less certain. Thus, we aimed to assess the impact of DTBT on long-term mortality in high- and low-risk STEMI patients. ⋯ A DTBT ≤90min was associated with improved short- and long-term outcomes in high- and low-risk STEMI patients. However, it was only an independent predictor of long-term survival in LR-STEMI patients.
