CONCLUSIONS In this large-scale, randomized trial, treatment of noncomplex obstructive coronary artery disease with an everolimuseluting bioresorbable vascular scaffold, as compared with an everolimus eluting cobalt–chromium stent, was within the prespecified margin for noninferiority with respect to targetlesion failure at 1 year. © 2012 MFMER | slide-36

Definition of “Firestorm” A firestorm is a usually stationary fire which attains such intensity that it creates and sustains its own wind system. It is most commonly a natural phenomenon, created during some of the largest bushfires, forest fires, and wildfires. The Black Saturday bushfires, the Great Peshtigo Fire and the Ash Wednesday fires are examples of firestorms. Firestorms can also be deliberate effects of targeted explosives such as occurred as a result of the aerial bombings of Dresden, Hamburg, Stalingrad, Tokyo, the atomic bombing of Hiroshima and Nagasaki and The Blitz during World War II. © 2012 MFMER | slide-51

CONCLUSIONS AND RELEVANCE Since the publication of the Appropriate Use Criteria for Coronary Revascularization in 2009, there have been significant reductions in the volume of nonacute PCI. The proportion of nonacute PCIs classified as inappropriate has declined, although hospital-level variation in inappropriate PCI persists. © 2016 MFMER | 3507693 -64

Methods – Models to Predict Ischemic and Bleeding Events Development of 2 Prediction Models within the randomized DAPT Study population (n=11, 648) • Ischemic Model: Myocardial infarction or stent thrombosis between 12 -30 months after index PCI; includes fatal events • Bleeding Model: GUSTO moderate or severe bleeding between 12 -30 months after index PCI; includes fatal events • Cox regression, stepwise selection among 37 candidate variables, including randomized treatment arm. In addition, several interaction terms with treatment arm evaluated. P value of 0. 05 for retention • Validated externally within the PROTECT trial population* *Camenzind, Wijns, Mauri et al: Lancet; 380; 9851: 1396 -1405 © 2015 MFMER | 3484963 -104

Conclusions Among patients who have not had a major ischemic or bleeding event within the first year after PCI: The DAPT Score identified patients for whom ischemic benefits outweighed bleeding risks, and patients for whom bleeding risks outweighed ischemic benefits Low DAPT Score (<2) NNT to prevent ischemia = 153 NNH to cause bleeding = 64 -2 High DAPT Score 2 NNT to prevent ischemia = 34 NNH to cause bleeding = 272 10 DAPT Score may help clinicians decide who should, and who should not be treated with extended DAPT © 2015 MFMER | 3484963 -118
