Abstract Background Takotsubo syndrome (TTS) is an acquired form of cardiomyopathy. National Brazilian data on this condition are scarce. The Takotsubo Multicenter Registry (REMUTA) is the first to include multicenter data on this condition in Brazil. Objective To describe the clinical characteristics, prognosis, in-hospital treatment, in-hospital mortality, and mortality during 1 year of follow-up. Methods This is an observational, retrospective registry study including patients admitted to the hospital with diagnosis of TTS and patients admitted for other reasons who developed […]

Abstract Background Multicenter registries representing the real world can be a significant source of information, but few studies exist describing the methodology to implement these tools. Objective To describe the process of implementing a database of ST-segment elevation acute myocardial infarction (STEMI) at a reference hospital, and the application of this process to other centers by means of an online platform. Methods In 2009, our institution implemented an Registry of Acute Myocardial Infarction (RIAM), with the prospective and consecutive inclusion […]

Background: Despite its great relevance, there are no studies in our country evaluating the application of the 2012 guidelines for the appropriate use of cardiac diagnostic catheterization.

Methods: This is a multicenter cross-sectional study, which analyzed indications, results and proposals for the treatment of 737 coronary angiograms performed in a tertiary hospital with multiple specialties (Hospital A) and a tertiary cardiology hospital […]

Abstract Background: Gender-related differences have been reported in patients with acute coronary syndrome. The description of this comparative finding in a Brazilian registry has not yet been documented. Objective: To compare male vs. female patients regarding the baseline characteristics, coronary findings, treatment and in-hospital and long-term prognosis. Methods: This is a retrospective, multicenter and observational study that included 3,745 patients (2,437 males and 1,308 females) between May 2010 and May 2015. The primary in-hospital outcome was all-cause mortality. The secondary […]
