INTRODUCTION AND OBJECTIVES To investigate the prevalence, causes and outcome of catheterization laboratory false alarms (CLFAs) in a regional primary angioplasty network. METHODS A prospective registry of 1,662 patients referred for primary angioplasty between January 2003 and August 2008 was reviewed to identify CLFAs (i.e. when no culprit coronary(More)
BACKGROUND In patients with ST-segment elevated myocardial infarction (STEMI), early post-thrombolysis routine angioplasty has been discouraged because of its association with high incidence of events. The GRACIA-1 trial was designed to reassess the benefits of an early post-thrombolysis interventional approach in the era of stents and new antiplatelet(More)
AIMS To compare the efficacy and tolerability of the antiplatelet agent triflusal with aspirin in the prevention of cardiovascular events following acute myocardial infarction. METHODS AND RESULTS In this double-blind, multicentre, sequential design study, patients were randomized within 24 h of acute myocardial infarction symptom onset to receive(More)
AIMS To compare primary percutaneous coronary intervention (pPCI) and fibrinolysis in very old patients with ST-segment elevation myocardial infarction (STEMI), in whom head-to-head comparisons between both strategies are scarce. METHODS AND RESULTS Patients ≥75 years old with STEMI <6 h were randomized to pPCI or fibrinolysis. The primary endpoint was a(More)
AIMS In patients with acute myocardial infarction and ST-segment elevation (STEMI), primary angioplasty is frequently not available or performed beyond the recommended time limit. We designed a non-inferiority, randomized, controlled study to evaluate whether lytic-based early routine angioplasty represents a reasonable reperfusion option for victims of(More)
Chronic heart failure (HF) is a cardiovascular disease of cardinal importance because of several factors: a) an increasing occurrence due to the aging of the population, primary and secondary prevention of cardiovascular events, and modern advances in therapy, b) a bad prognosis: around 65% of patients are dead within 5 years of diagnosis, c) a high(More)
AIMS Cardiotrophin-1 (CT-1) is a cytokine that induces hypertrophy in cardiomyocytes and is associated with left ventricular hypertrophy (LVH) in hypertensive patients. The objective of this study was to evaluate whether plasma CT-1 is associated with hypertrophic cardiomyopathy (HCM). METHODS AND RESULTS The study was performed in 124 patients with HCM.(More)
BACKGROUND MyBPC3 mutations are amongst the most frequent causes of hypertrophic cardiomyopathy, however, its prevalence varies between populations. They have been associated with mild and late onset disease expression. Our objectives were to establish the prevalence of MyBPC3 mutations and determine their associated clinical characteristics in our(More)
INTRODUCTION AND OBJECTIVES To determine the effectiveness of a primarily educational intervention in heart failure (HF) patients implemented in a home care unit. METHODS This randomized controlled clinical trial involved 279 HF patients who were discharged from a tertiary-care hospital between February 2001 and June 2002. Patients with dementia, terminal(More)
Genetic studies can play a key role in the comprehensive evaluation of familiar hypertrophic cardiomyopathy and in the development of individualized medicine. Although only a few cases have been described, there exists a group of patients with complex genotypes that are associated with severe disease manifestations and a high risk of sudden death. We(More)
