Greater platelet reactivity in diabetic patients receiving DES and clopidogrel
Original title: Impact of diabetes mellitus and metabolic syndrome on acute and chronic on-clopidogrel platelet reactivity in patients with stable coronary artery disease undergoing drug-eluting stent placement. Reference: Feldman L. et al. Am Heart J. 2014; Epub ahead of print. Diabetes mellitus type 2 (T2DM) or metabolic syndrome patients undergoing drug eluting stent implantation have 3 to 4…
The higher the bleeding risk, the greater the benefit of radial access in terms of mortality
Original title: Baseline bleeding risk and arterial access site practice in relation to procedural outcomes after percutaneous coronary intervention. Presenter: Mamas A. Mamas et al. J Am Coll Cardiol. 2014;64:1554-1564. The transradial approach has been associated with reduced access site related bleeding complications as well as a reduced mortality in the context of PCI. It seems…
Outcomes are still associated to operator experience and institutional volume
This study is a retrospective analysis of 2,243,209 PCI stenting procedures in the USA between 2005 and 2009. During this period, a reduction in the number of PCI procedures was observed (also observed globally) from 53 in previous years to 33 procedures per operator per year, and from 1,024 to 693 per hospital per year.…
Worse post TAVI ejection fraction recovery in coronary artery disease patients without revascularization
Original title: Impact of coronary artery disease on left ventricular ejection fraction recovery following transcatheter aortic valve implantation. Reference: Freixa X et al. Catheter Cardiovasc Interv. 2014;Epub ahead of print. This single center study analyzed data form 56 consecutive patients with severe aortic stenosis and LVEF of ≤ 50% undergoing TAVI (transcatheter aortic valve implantation) between March 2006…
Most of stable patients have the wrong idea about the purpose of PCI
Original title: Variation in patients’ perceptions of elective percutaneous coronary intervention in stable coronary artery disease: cross sectional study. Referencia: Kureshi F et al. BMJ. 2014;Epub ahead of print. This study included 991 consecutive patients with stable coronary disease undergoing elective PCI in 10 university and community centers between 2009 and 2011. After procedure, patients were asked a…
Mitra-Clip: a valid alternative for high risk patients
Original title: Percutaneous Mitral Valve Repair for Mitral Regurgitation in High-Risk Patients. Results of the EVEREST II Study. Reference: Donald D. Glower et al. J Am Coll Cardiol 2014;64:172-81 Severe mitral regurgitation (MR) often lead to hospitalization for cardiac failure and heart surgery. Half of these patients are rejected for high surgical risk. Percutaneous intervention is a valid…
Similar mortality outcomes with MitraClip and surgery in high risk patients with severe mitral valve regurgitation
Original title: Survival of transcatheter mitral valve repair compared with surgical and conservative treatment in high-surgical-risk patients. Reference: Swaans MJ et al. J Am CollCardiolIntv. 2014;7:875-881. In high-surgical-risk patients with symptomatic severe mitral valve regurgitation, MitraClip for transcatheter mitral valve repair and surgery showed similar survival rates in addition to superiority when compared to standard medical treatment. This…
Less Definite Thrombosis with Everolimus Eluting Stents
Original title: Three-Year Outcomes After Revascularization With Everolimus-and Sirulimus -Eluting Stents From the SORT OUT IV Trial. Reference: Lisette Okkels Jensen et al. J Am CollCardiolIntv, 2014;7: 840-8. Drug eluting stents (DES) have been shown to safely and effectively reduce restenosis compared to bare-metal stents. While the risk of thrombosis remains a matter of concern when it comes…
Resistance to Aspirin Associated to Greater Risk of In-Stent Thrombosis and Death
Original title: Aspirin Treatment and Outcomes After Percutaneous Coronary InterventionResults of the ISAR-ASPI Registry. Reference: Katharina Mayer et al. J Am CollCardiol. 2014;64(9):863-871. Aspirin administration, as part of the double antiagregation scheme, is essential in the context of PCI. The correlation between high platelet reactivity to on-clopidogrel treatment and higher events rates has been well established, while data…
