BACKGROUND The aim of the present study was to investigate the prognostic implication of myocardial perfusion in patients with ST-segment-elevation myocardial infarction (STEMI) and signs of heart failure, treated with primary angioplasty. METHODS AND RESULTS Our population is represented by 1548 consecutive patients undergoing primary angioplasty for STEMI. Congestive heart failure was defin...

OBJECTIVE To identify the clinical and demographic predictors of in-hospital mortality in acute myocardial infarction with elevation of the ST segment in a public hospital, in the city of Fortaleza, Ceará state, Brazil. METHODS A retrospective study of 373 patients experiencing their first episode of acute myocardial infarction was carried out. Of the study patients, 289 were discharged from ...

INTRODUCTION AND OBJECTIVES Tako-tsubo syndrome produces a variable degree of transient left ventricular dysfunction. Our objective was to determine the short- and long-term prognosis of this syndrome, the incidence of and risk factors for the development of heart failure, and the influence on heart failure on the long-term outcome in our patient population. METHODS We prospectively recorded ...

background :impact of substance abuse on outcome of hospitalized patients with acute myocardial infarction (mi) is a frequent question. available studies show disagreements over its impact, thus we performed this study to find a clear answer.   methods : in a cross sectional study, 304 patients (include 152 consecutive opium dependents and equal number of independents) with acute mi admitted to...

BACKGROUND Mortality in patients with acute myocardial infarction (AMI) has improved substantially with modern therapy including percutaneous coronary interventions (PCI) but remains high in certain subgroups such as patients presenting with overt cardiogenic shock. However, the risk for AMI in patients presenting acutely with signs of heart failure but without cardiogenic shock is less well de...

This study evaluated brain natriuretic peptide (BNP) release in acute myocardial infarction (AMI), absolute values as well as pattern of its release. There are two different patterns of BNP release in AMI; monophasic pattern--concentration in the first measurement is higher than in the second one, and biphasic pattern--concentration in the first measurement is lower than in the second one. We o...

BACKGROUND The impact of primary percutaneous coronary intervention (PCI) for acute ST-elevated myocardial infarction (STEMI) on the incidence of ischemic mitral regurgitation (IMR) is unclear. METHODS AND RESULTS Between January 2000 and December 2004, 318 patients presenting with first acute STEMI were enrolled in this study. Two hundred and twelve (66.67%) patients received PCI (PCI group)...

OBJECTIVES: To study the relationship between serum uric acid level and Killip classification in pateints with acute myocardial infarction (MI), and the use of serum uric acid levels as a marker of short-term mortality. METHODS: The present study involved 50 patients with acute MI and 50 controls. Serum uric acid level was measured on days 0, 3 and 7 of MI, and compared with all clinical parame...

STUDY OBJECTIVE To evaluate the incidence and clinical factors related to the persistence of infarct-associated pericardial effusion (PE) after primary angioplasty. DESIGN Consecutive case-series analysis. SETTING Coronary care unit in a university hospital. PATIENTS Three hundred ninety-one consecutive patients with acute myocardial infarction (AMI) who underwent successful primary percu...

BACKGROUND The Killip classification categorizes heart failure (HF) in acute myocardial infarction, and has a prognostic value. Although non-ST-elevation myocardial infarction (NSTEMI) is increasing steadily, little information is available about the prognostic value of low Killip class in this scenario. Our aim was to assess the prognostic value of mild HF in NSTEMI. METHODS 835 patients wit...
