Original title: Association of Clopidogrel Pretreatment with mortality, Cardiovascular events, and Major Bleeding among patients undergoing percutaneous coronary intervention. A systematic review and Mata-analysis. Reference: Anne Bellemain-Appaix, MD et al. for the ACTION group. The loading of clopidogrel before coronary angioplasty is an accepted practice by most clinical and interventional cardiologists but, nevertheless, it is only based on...
Reference: Charlot et al. European Heart Journal 2012 (in press). International guideline recommendations approve giving dual antiplatelet therapy for a period of not less than 12 months after acute myocardial infarction. However, the benefit is unknown if the therapy is extended beyond 12 months. Perhaps its extension could be particularly useful in patients receiving pharmacological...
James SK, Storey RF, Khurmi N, et al. Ticagrelor versus Clopidogrel in Patients with Acute Coronary Syndromes and a History of Stroke or Transient Ischemic Attack. Circulation 2012. A sub-analysis of the PLATO study demonstrated similar superiority and the safety of ticagrelor in all patients, regardless of any previous history of stroke. Ticagrelor versus clopidogrel:...
Platelet Inhibition in the PLATO study: insights from the ECG substudy. En el Estudio PLATO quedó evidenciado que el Ticagrelor disminuyó la mortalidad a 12 meses en comparación con el Clopidogrel en el tratamiento de pacientes post-angioplastía por un síndrome coronario agudo o por un cuadro estable (4,5 vs. 5,9%; P<0.001). Estos resultados fueron del...
Percutaneous left atrial appendage occlusion (LAAO) has surged as an effective alternative to treat patients with atrial fibrillation (AF) presenting counterindications for oral anticoagulants. However, the optimal antithrombotic treatment after LAAO is still debated, seeing as it should prevent device related thrombosis (DRT) while minimizing bleeding risk. The aim of this retrospective study carried out...
Failure of a mitral bioprosthesis always poses a challenge regarding decision-making, especially when dealing with elderly patients with multiple risk factors. The scenario is worsened by the high risk associated with a new sternotomy and the significant impact of undergoing new surgery. Transcatheter mitral valve-in-valve (TMViV) replacement is emerging as a valid strategy in the...
Aortic stenosis shares risk factors with coronary artery disease (CAD), and its prevalence varies according to age, reaching approximately 50% or more in some registries. Deciding when to treat and the need for percutaneous intervention presents a challenge. It has been established that epicardial stenosis at proximal level, or the medial segment, requires intervention, especially...
In patients with peripheral vascular disease (PVD), the presence of diabetes has been significantly associated with increased failure of critical lower limb ischemia (CLI) treatment, and higher incidence of amputation. This relationship has been attributed mainly to comorbidities and patient characteristics, concomitant peripheral neuropathy and marked microvascular alteration. Also, a high proportion of these patients...
While the benefits of dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor are recognized, its primary complication is the occurrence of bleeding events, which negatively impact patient morbidity and mortality. Additionally, about 10% of patients undergoing percutaneous coronary intervention (PCI) are on oral anticoagulant therapy, which significantly increases the risk of bleeding when...
Lesions in the left main coronary artery (LMCA) continue to pose a significant challenge. The use of coronary imaging before percutaneous coronary implantation (PCI) has proven useful in analyzing the lesion, identifying the presence and location of calcification, and determining lesion length in the LMCA, the left anterior descending artery, and the circumflex artery. Various...
