The REC-CAGEFREE trial showed that drug-coated balloons (DCB) did not achieve non-inferiority in the treatment of non-complex de novo lesion compared to a strategy drug-eluting stents (DES). However, prespecified subgroup analysis arteries sized <3.0 mm revealed no difference device-oriented outcome DES. aim present study was validate finding real-world registry by comparing DCB and DES lesions with mm.

Background Balloon angioplasty with drug‐coated balloons (DCBs) is frequently used during percutaneous coronary intervention for in‐stent restenosis. Despite its frequent use, there a lack of long‐term data on the efficacy DCB angioplasty. We conducted an investigation outcome restenosis, comparing DCBs, drug‐eluting stents, and plain old balloon Methods Results nationwide analysis from SCAAR (Swedish Coronary Angiography Angioplasty Registry) including restenosis lesions undergoing...

Objective The comparative efficacy and safety of prasugrel ticagrelor in patients with myocardial infarction (MI) treated percutaneous coronary intervention (PCI) remain unclear. We aimed to investigate the association treatment clinical outcomes. Methods In SWEDEHEART (Swedish Web-system for enhancement development evidence-based care heart disease evaluated according recommended therapies) registry, all MI PCI discharged on or from 2010 2016 were included. Outcomes 1-year major adverse...

Abstract Aims Previous studies on disparities in healthcare and outcomes have shown conflicting results. The aim of this study was to assess differences baseline characteristics, management, myocardial infarction (MI) patients, by country birth. Methods results In total, 194 259 MI patients (64% male, 15% foreign-born) from the nationwide SWEDEHEART (The Swedish Web-system for Enhancement Development Evidence-based care Heart disease Evaluated According Recommended Therapies) registry were...

Background: In patients with chronic coronary syndrome undergoing percutaneous intervention, the optimal timing of P2Y12 inhibitors’ administration is uncertain. We compared pretreatment versus treatment in catheterization laboratory (In-Cathlab) a real-world population. Methods: Swedish Coronary Angiography and Angioplasty Registry, all angiography ad hoc between 2006 2017 were identified. Pretreatment was defined as inhibitor before angiography, outside laboratory. Outcomes net adverse...

Abstract Background During the last decades, there have been substantial improvements in treatment techniques for percutaneous coronary intervention (PCI). Yet, in-stent restenosis (ISR) continues to pose significant challenges as they account 10% of all PCI cases and are associated with worse outcome compared de-novo lesions. When assessing ISR PCI, balloon angioplasty drug-coated balloons (DCB) is frequently used. Purpose Despite frequent use DCB, a lack long-term data ensuring safety DCB...

Abstract Background Antithrombotic treatment with oral anticoagulants is recommended in clinical practice guidelines for patients myocardial infarction (MI) undergoing percutaneous coronary intervention (PCI) and concurrent atrial fibrillation (AF). Previous randomized controlled trials comparing warfarin DOAC have primarily focused on bleeding complications. Consequently, the benefits risks an all-comer population remain uncertain. Purpose This study aimed to evaluate adherence within a...

Abstract Introduction Immigration is increasing in most European countries. Little known about differences baseline characteristics and outcome between foreign-born native patients with myocardial infarction (MI). Purpose To investigate one-year mortality after an MI, based on region of birth. Methods We included 194 498 MI (36% women) 2005 2016 from the SWEDEHEART registry compared them according to birth: Sweden (Sw, n=166020), Other Nordic countries (No, n=10856), EU except (EU, (n=6301),...
