Performance of the Micra cardiac pacemaker in nonagenarians.

Introduction And Objectives: The Micra transcatheter pacing system has shown high effectiveness and a lower complication rate than conventional transvenous pacemakers. However, the benefit of the device is unknown in the very old population (≥ 90 years). The aim of this study was to evaluate the safety and effectiveness of Micra in patients ≥ 90 years.

[Combined high-sensitivity copeptin and troponin T evaluation for the diagnosis of non-ST elevation acute coronary syndrome in the emergency department].

Objectives: To assess the diagnostic yield of a high-sensitivity copeptin (hs-copep) assay alone or in combination with a high-sensitivity cardiac troponin T (hs-cTnt) assay for the diagnosis of non-ST segment elevation acute coronary syndrome (NSTEMI) in patients with chest pain in the emergency department (ED). The secondary aim was to assess the 1-year prognostic utility of these biomarkers in this clinical context.

Material And Methods: Retrospective observational study of a series of patients attended for chest pain suggesting myocardial ischemia in 5 Spanish ED.

Antiphospholipid syndrome and acute myocardial infarction: treatment with thrombectomy and abciximab.

Antiphospholipid syndrome (APS) is an autoimmune coagulation disorder that manifests clinically as venous and arterial thrombosis, and may affect any tissue or organ. Coronary artery involvement, however, is very rare. Case reports in the literature describing patients with coronary acute syndrome and APS treated with coronary angioplasty show conflicting results.

Using high-sensitivity troponin T: the importance of the proper gold standard.

Objective: The study objective was to determine how best to use high-sensitivity cardiac troponin T (hscTnT) to diagnose myocardial infarction.

Methods: A total of 358 patients presenting with acute coronary syndromes sampled at admission and 2, 4, and 6 to 8 hours. Both contemporary cardiac troponin T (cTnT) and hscTnT were measured.

[Hemosiderin-laden macrophages count in sputum in diagnosis of dyspnea of heart origin].

Background And Objective: The respiratory or heart origin of dyspnea is not always easy to find out using the available diagnostic tools. Many patients present both heart and lung diseases that cause dyspnea. The role of hemosiderin-laden macrophages count (HC) in sputum in this context has not been well settled so far.
