BACKGROUND Sudden cardiac death (SDC) is responsible for approximately 60-70% of deaths in New York Heart Association (NYHA) class II congestive heart failure (CHF) patients. Recently, microvolt-level T wave alternans has been proposed as a new noninvasive tool to identify CHF patients at risk for SCD and ventricular tachycardia/fibrillation (VT/VF). (More)
BACKGROUND Availability of a telematic system of electrocardiogram (ECG) transmission may improve the management of ST-elevation myocardial infarction (STEMI), by reducing time to treatment. The aim of this study was to show the effectiveness of telephone transmission of ECG in improving quality of care for patients with acute STEMI. METHODS Since January(More)
RE-START is a multicenter, randomized, prospective, open, controlled trial aiming to evaluate the feasibility and the short- and medium-term effects of an early-start AET program on functional capacity, symptoms and neurohormonal activation in chronic heart failure (CHF) patients with recent acute hemodynamic decompensation. Study endpoints will be: 1)(More)
BACKGROUND The first few months after admission are the most vulnerable period in patients with acute decompensated heart failure (ADHF). METHODS AND RESULTS We assessed the association of the updated ADHF/N-terminal pro-B-type natriuretic peptide (NT-proBNP) risk score with 90-day and in-hospital mortality in 701 patients admitted with advanced ADHF,(More)
BACKGROUND Although the prognostic value of right ventricular dysfunction in chronic heart failure (HF) has been studied extensively, it remains insufficiently characterized in the setting of acute decompensated HF (ADHF). We sought to assess whether measurement of tricuspid annular plane systolic excursion (TAPSE) or TAPSE-to-estimated pulmonary arterial(More)
