Abstract
BACKGROUND The role of percutaneous coronary interventions (PCI) in patients with diabetes mellitus and multi-vessel disease has been questioned by the results of the FREEDOM trial, which showed superiority of coronary artery bypass graft(CABG) over first generation drug-eluting stents (DES) including a reduction in mortality. In the light of safer and more efficacious stents and significantly better medical management, those results that date back to 2012 need to be revisited. TUXEDO-2 is a study designed to compare two contemporary stents in Indian diabetic patients with multi-vessel disease. AIMS The primary objective of the TUXEDO-2 study is to compare the clinical outcomes of PCI with ultra-thin Supraflex Cruz vs Xience when combined with contemporary optimal medical therapy (OMT) in diabetic patients with multi-vessel disease. The secondary objective is to compare clinical outcomes between a pooled cohort from both arms of the study (Supraflex Cruz + Xience; PCI arm) vs CABG based on a performance goal derived from the CABG arm of the FREEDOM trial (historical cohort). The tertiary objective is a randomized comparison of ticagrelor vs prasugrel in addition to aspirin for the composite of ischemic and bleeding events. METHODS In this prospective, open-label, multi-centre, 2 × 2 factorial, randomized, controlled study, 1,800 patients with diabetes mellitus and multi-vessel disease (inclusion criteria similar to FREEDOM trial) with indication for coronary revascularization will be randomly assigned to Supraflex Cruz or Xience stents and also to ticagrelor- or prasugrel- based antiplatelet strategies. All patients will receive guideline directed OMT and optimal PCI including image- and physiology-guided complete revascularization where feasible. The patients will be followed through five years to assess their clinical status and major clinical events. The primary endpoint is a non-inferiority comparison of target lesion failure at one-year for Supraflex Cruz vs Xience (primary objective) with an expected event rate of 11% and a non-inferiority margin of 4.5%. For PCI vs CABG (secondary objective), the primary endpoint is major adverse cardiac events (MACE), defined as a composite of all cause death, nonfatal myocardial infarction, or stroke at one-year and yearly up to five years, with a performance goal of 21.6%. For ticagrelor vs prasugrel (tertiary objective), the primary endpoint is composite of death, myocardial infarction, stroke, and major bleeding as per the Bleeding Academic Research Consortium (BARC) at one-year with expected event rate of 15% and a non-inferiority margin of 5%. CONCLUSIONS The TUXEDO-2 study is a contemporary study involving state-of-the-art PCI combined with guideline directed OMT in a complex subset of patients with diabetes mellitus and multi-vessel disease. The trial will answer the question as to whether a biodegradable polymer coated ultra-thin Supraflex Cruz stent is an attractive option for PCI in diabetic patients with multi-vessel disease. It will also help address the question whether the results of FREEDOM trial would have been different in the current era of safer and more efficacious stents and modern medical therapy. In addition, the comparative efficacy and safety of ticagrelor vs prasugrel in addition to aspirin will be evaluated. (CTRI/2019/11/022088).

Abstract
BACKGROUND Early stent thrombosis following coronary angioplasty is associated with high mortality and morbidity. Different methods of treatment, including emergency coronary angioplasty, have been tried, but with variable results. This is a study of the results of systemic thrombolytic therapy in the treatment of early stent thrombosis. METHODS Eight patients, who developed acute chest pain and ST-segment elevation within the first few days of coronary stenting, were administered 1.5 million units of streptokinase or urokinase and followed up for acute and long-term events. RESULTS Seven patients responded well. The ST-segment resolution was excellent and the clinical outcome good. One patient who presented late after the onset of chest pain and received urokinase, expired. CONCLUSION Systemic thrombolytic therapy seems to compare favorably with emergency coronary angioplasty in the treatment of early coronary stent thrombosis. Further experience is required to define its role better.
