The clinical definition of cardiogenic shock is that of a low cardiac output and evidence of tissue hypoxia in the presence of adequate blood volume. Cardiogenic shock is the main cause of death related to acute myocardial infarction (AMI), with a mortality rate of 45-70% in the absence of aggressive and highly specialized technical care. The intra-aortic balloon pump (IABP) is one of the most widely used mechanical assisting devices. During the last two decades, about 42% of patients with AMI who evolved with cardiogenic shock received mechanical circulatory assistance with IABP...

Background: According to common belief, most myocardial infarctions (MIs) are due to the rupture of nonsevere, vulnerable plaques with < 70% obstruction. Data from recent trials challenge this belief, suggesting that the risk of coronary occlusion is, in fact, much higher after severe stenosis. The aim of this study was to investigate whether or not acute ST-elevation MIs result from high-grade stenoses by evaluating the presence of coronary collateral circulation (CCC). Methods: We retrospectively included 207 consecutive patients who had undergone primary percutaneous coronary intervention for acute ST-elevation MI...

Background: A few decades ago, patients with Chagas disease were predominantly rural workers, with a low risk profile for obstructive coronary artery disease (CAD). As urbanization has increased, they became exposed to the same risk factors for CAD of uninfected individuals. Dobutamine stress echocardiography (DSE) has proven to be an important tool in CAD diagnosis. Despite being a potentially arrhythmogenic method, it is safe for coronary patients without Chagas disease. For Chagas disease patients, however, the indication of DSE in clinical practice is uncertain, because of the arrhythmogenic potential of that heart disease...

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 composite of all-cause mortality, re-infarction, or disabling stroke at 30 days. The trial was prematurely stopped due to slow recruitment after enrolling 266 patients (134 allocated to pPCI and 132 to fibrinolysis)...

BACKGROUND: We tried to evaluate a putative negative effect on coronary atherosclerosis in patients receiving intracoronary infusion of unfractionated bone marrow mononuclear cells (BMMC) following an acute ST-elevation myocardial infarction. Peripheral blood mononuclear cells or enriched CD133(+) BMMC have been associated with accelerated atherosclerosis of the distal segment of the infarct related artery (IRA). METHODS: Thirty-seven patients with ST-elevation myocardial infarction from the TECAM pilot study underwent intracoronary infusion of autologous BMMC 9 +/- 3...

OBJECTIVES: The paradoxical effect of smoking after acute myocardial infarction (AMI) is a phenomenon consisting of a reduction in the mortality of smokers compared to nonsmokers. However, it is not known whether the benefit of this reduction in mortality is due to smoking itself or to other covariables. Despite acceptance of the paradoxical effect of smoking in AMI, it is not known whether a similar phenomenon occurs in unstable angina. The objective of this study was to investigate the paradoxical effect of smoking in AMI and unstable angina, and to study specifically whether smoking is an independent prognostic variable...

Aspirin (ASA) and angiotensin-converting enzyme inhibitor (ACEi) therapy reduce mortality when administered early after the onset of myocardial infarction. ASA can antagonize some effects of ACEi therapy by inhibiting the synthesis of vasodilating prostaglandins; however, the evidence for this effect from large controlled trials is contradictory. The authors analyzed a database of 18,895 patients of the Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardio-3 (GISSI-3) Trial in which patients were allocated either to receive lisinopril or not to receive lisinopril within 24 hours of the onset of symptoms of myocardial infarction...

The progressive aging of the population is associated with an increase in the proportion of very old patients (greater than 75 years) hospitalized with acute myocardial infarction. The lack of evidence regarding the efficacy of most therapeutic interventions for acute myocardial infarction in these patients is leading to a significant degree of uncertainty in the cardiology community with respect to their optimal management. When aggressive treatment (defined as a therapeutic strategy designed to obtain and maintain a patent infarct-related coronary artery at an early moment) of acute myocardial infarction is considered in very old patients, three main questions should be addressed: why should we treat? Whom should we treat? And how should we treat? To answer these questions, the authors reviewed the data available in the literature as well as new data from the PPRIMM75 (Pronóstico del PRimer Infarto de Miocardio en Mayores de 75 aÃ+/-os) Registry, a large, prospective database of patients aged 75 years or older, admitted to a single coronary care unit in Madrid, Spain, for their first acute myocardial infarction during the last decade...

The objectives of this study were to improve thrombolytic therapy in acute myocardial infarction by reducing the "door-to-needle" time in a 285-bed university hospital in Spain. A quality management approach was used involving all the relevant staff. Target standard was set at 35 minutes. Baseline data, intervention effect, and continuous monitoring were analyzed using x control charts. Analysis of baseline data showed a wide out-of-control variation and 72 minutes' average delay. Cause analysis revealed organizational and clinical problems that were subjected to intervention...
