Overview of acute decompensated heart failure in Argentina: lessons learned from 5 registries during the last decade.

Background: The acute decompensated heart failure (ADHF) is not as well characterized as the chronic phase, particularly in Latin American countries. Thus, the aim of this overview was to describe the clinical profile, treatment, and inhospital course of ADHF during the last decade in Argentina.

Methods: Results obtained from 5 Argentinean prospective and multicenter registries, involving 2974 patients admitted for ADHF, were assessed.

A simple prediction rule for significant renal artery stenosis in patients undergoing cardiac catheterization.

Background: Renal artery stenosis (RAS) is a potentially reversible cause of hypertension and renal insufficiency and is associated with poor prognosis.

Methods: We aimed to identify simple predictors of significant RAS among patients undergoing coronary angiography. Prospective data were collected on 843 consecutive patients who underwent cardiac catheterization and abdominal aortography.

Early reperfusion and late clinical outcomes in patients presenting with acute myocardial infarction randomly assigned to primary percutaneous coronary intervention or streptokinase.

Background: Primary percutaneous coronary intervention (PCI) has become an alternative to thrombolytic therapy as a reperfusion strategy for ST-elevation acute myocardial infarction (AMI).

Methods: The main goal of this study was to determine whether PCI and thrombolytic therapy achieve comparable reperfusion rates, as evidenced by ST-segment resolution. Secondary end points included infarct vessel patency rates before hospital discharge and short- and long-term outcomes.
