CPORT- E Trial Randomized trial comparing outcomes of non-primary PCI at hospitals with and without on-site cardiac surgery
Motivation for Trial Sustain primary PCI program at no-SOS hospitals Improve access to PCI services Reduce pressure to create additional cardiac surgery programs Need for research to inform healthcare policy decisions by state and national organizations
C-PORT Elective Patient for Diagnostic Cath Informed consent Catheterization Meets inclusion criteria PCI no SOS PCI with SOS Exclusion criteria Consent Registry Refuse No Consent Registry Not Approached 3:1 Randomization
Study Endpoints Non-inferiority trial Primary Endpoints All-cause mortality at 6 weeks MACE at 9 months All-cause mortality Q-wave myocardial infarction Target vessel revascularization Assuming 6 week mortality to be 0.8%, a sample size of 18360 was selected to define a non-inferiority margin of 0.4% with a one-sided test for non-inferiority using α=0.05 and β=0.80 for both primary endpoints.
Inclusion and Exclusion Criteria Patient Institution Inclusion Age > 18 years Informed consent > 50% stenosis All target lesions approachable at no-SOS hospital Exclusion Unprotected LM EF < 20% MD-judged high risk Devices Inclusion Balloon, stent Distal protection Covered stent Cutting balloon - in-stent restenosis Exclusion Atherectomy Cutting balloon- de novo lesion Inclusion > 200 PCI/year 24/7 Primary PCI Complete formal development program Interventionalist meets AHA/ACC competency

Mortality 6- Weeks No-SOS (%) SOS (%) P-value Death0.910.930.94 The difference in 6 week mortality is -0.014% with a 90% confidence interval of -0.26% to 0.28%. The upper bound is <0.4%, so that the hypothesis of inferior 6 week mortality for the no-SOS hospitals is rejected at the one-sided P<0.05 level.
Summary Angiographic Outcomes PCI Success > 90% in both groups but lower in hospitals without surgery on-site (success rate difference of 1.1% on per patient basis; 0.7% on per lesion basis) Number of catheterization laboratory visits required to complete the index PCI is greater in patients randomized to hospitals with surgery on-site (1.3 versus 1.7 visits/patient) Unplanned procedure outcomes Unplanned catheterization and PCI procedures were uncommon but occurred more frequently in patients randomized to hospitals without surgery on-site (4.4% no-SOS vs 3.4% SOS) Emergency coronary CABG was rarely required, but was utilized more among patients at hospitals with surgery on-site (0.1% no-SOS vs 0.2% SOS) Patient Outcomes Mortality is similar in both groups (0.91% no-SOS vs 0.93% SOS) The incidence of bleeding, vascular repair, stroke and renal failure is similar in both groups
Conclusion In hospitals without on-site cardiac surgery that complete a formal PCI development program, adhere to C-PORT participation requirements, and whose outcomes are monitored, non-primary PCI is safe and associated with similar rates of adverse events including mortality. Long-term, quality outcome data are currently being collected on these study subjects and will be reported early in 2012.
