BACKGROUND: In the emergency room, the shock index was applied to determine the prognosis in various pathologies, such as acute infarction. The shock index is the re-sult of dividing heart rate by the systolic blood pressure. OBJECTIVE: To determine the relationship between the systolic shock index and the di-astolic shock index as prognostic factors for mortality in acute myocardial infarction with ST segment elevation prior to admission to the Hemodynamics Room...

The right ventricle is susceptible to changes in preload, afterload, and contractility. The answer is its dilation with dysfunction/acute failure; filling is limited to the left ventricle and cardiac output. Systemic venous congestion is retrograde to the right heart, it is involved in the genesis of cardiogenic shock due to right ventricle involvement. This form of shock is less well known than that which occurs due to left ventricular failure, therefore, treatment may differ. Once the primary treatment has been carried out, since no response is obtained, supportive treatment aimed at ventricular pathophysiology will be the next option...

INTRODUCTION AND OBJECTIVES: Myocardial infarction (MI) incidence and case fatality trends are highly informative but relatively untested at the population level. The objective of this work was to estimate MI incidence and case fatality in the Girona population aged 35-74 years, and to determine their 30-year trends (1990-2019). METHODS: The REGICOR (Girona Heart Registry) monitored MI incidence and case fatality rates from 1990 to 2008. For the period 2008 to 2019, we linked discharges from Girona hospitals (n = 4 974 977) and mortality registry (n = 70 405) during 2008-2019...

BACKGROUND AND PURPOSE: Premature infarction has a high socioeconomic impact and we lack contemporary studies that analyze the characteristics associated with its development and evolution. MATERIAL AND METHODS: In an observational study on a retrospective cohort of patients younger than 46 years old, who had suffered from an infarction from June 2012 to June 2022, sociodemographic characteristics, cardiovascular and toxic risk factors, infarction characteristics, SARS-CoV-2 infection and immunization data were investigated...

BACKGROUND: Acute myocardial infarction is a major cause of mortality worldwide, and atherosclerotic plaque formation is the main pathophysiological mechanism, which results in chronic inflammation that induces erythrocyte maturation and may cause an increase in the red cell distribution width (RDW) index. OBJECTIVE: Evaluate the role of the anisocytosis index in patients with acute myocardial infarction in both types of infarctions as a predictor of severity. METHODS: Patients were included in the study according to the inclusion/exclusion criteria, following the hospital routine based on their clinical and laboratory history...

Superficial siderosis of the central nervous system is produced by the deposit of hemosiderin within the subpial layers of the central nervous system and central parts of the cranial nerves, leading to progressive degeneration. We report a 55-year-old male who consulted for hearing loss and long-standing progressive decrease in visual acuity, associated with sudden onset of left hemiparesis. A brain CAT scan showed subacute ischemic lesions in the territory of the right posterior cerebral artery (thalamus and right subcortical temporal regions), old ischemic lesions in the right subcortical occipital regions and cerebellar atrophy...

BACKGROUND: In those patients who do not have timely access to primary angioplasty, the pharmaco-invasive approach, that is, the use of thrombolysis as a bridging measure prior to the coronary angiography, is a safe alternative. AIM: To describe the features of patients with an acute ST-elevation myocardial infarction (STEMI) treated with a pharmaco-invasive strategy. MATERIAL AND METHODS: Descriptive observational study of 144 patients with mean age of 46 years with STEMI who received a dose of thrombolytic prior to their referral for primary angioplasty at a public hospital between 2018 and 2021...

Myocardial revascularization, either percutaneous or surgical, is the cornerstone of chronic and acute ischemic coronary artery disease therapy. Periprocedural myocardial injury and infarction are possible complications of these procedures. Several pathogenetic mechanisms have been proposed in the setting of percutaneous (distal embolism, vasospasm, obstruction of a minor vessel) or surgical revascularization (prolonged ischemic time, early graft failure, arrhythmia or severe hypotension during the procedure)...

BACKGROUND: Ischemic stroke is an important cause of death in the world. The malignant middle cerebral artery infarction (MMCAI) has mortality as high as 80% when clinically treated. In this setting, decompressive craniectomy is a life-saving measure, in spite of high morbidity among survivors. OBJECTIVE: To evaluate the outcomes of patients with MMCAI treated with decompressive craniectomy in a Brazilian academic tertiary stroke center. METHODS: A prospective stroke database was retrospectively evaluated, and all patients treated with decompressive craniectomy for MMCAI between January 2014 and December 2017 were included...

BACKGROUND: Myocardial ischemia (INOCA) and acute myocardial infarction with non-obstructive coronary artery disease (MINOCA) represent emerging entities in the landscape of interventional cardiology. These conditions have heterogeneous pathophysiological mechanisms and clinical presentations, complex diagnostics, and high prognostic significance. METHODS: This survey was carried out jointly by the GISE Young Committee with the support of the SICI-GISE Society and the ICOT group with the aim of evaluating the implementation of diagnostic-therapeutic pathways in cases of suspected/confirmed INOCA and MINOCA diseases...

The systematic use of coronary angiography and the availability of increasingly sensitive biomarkers of myocardial cytolysis have determined an increase in the diagnosis of myocardial infarction with non-obstructed coronary arteries (MINOCA), which is currently reported in 5-20% of patients with acute myocardial infarction. The first diagnostic criteria of MINOCA were reported by a position paper of the European Society of Cardiology in 2017; since then, these criteria have been revised several times until the current version...

BACKGROUND: Following ST-segment elevation myocardial infarction (STEMI), patients with cardiac dysfunction have limitations in performing physical activity. Right ventricular (RV) function is a determinant in improving functional capacity, and cardiac rehabilitation (CR) is essential for this patient cohort. OBJECTIVE: To evaluate the association of RV function with exercise tolerance after a CR program in patients with STEMI. METHODS: Retrospective cohort study in patients with STEMI from January to December 2019...

INTRODUCTION AND OBJECTIVES: Clinical and experimental studies have shown that, in patients with reperfused ST-segment elevation myocardial infarction (STEMI), abnormalities in the endothelial monolayer are initiated during ischemia but rapidly intensify upon restoration of blood perfusion to the ischemic area. We aimed to evaluate the effect of serum isolated after revascularization from STEMI patients on the degree of endothelial permeability in vitro, by promoting endothelial cell apoptosis and necrosis in vitro...

Kounis syndrome is defined as cardiovascular symptoms that occur secondary to allergic or hypersensitivity insults, and is also called allergic angina and allergic myocardial infarction. We report a case of pre-operative ceftriaxone-induced Kounis syndrome with no evident dermatological manifestation, and describe our diagnostic dilemma. The patient was symptomatically managed and discharged in stable condition with a warning against future use of ceftriaxone.

OBJECTIVE: The objective of the study is to identify clinical and angiographic characteristics of patients with ST-segment elevation myocardial infarction (STEMI) but without clinical manifestations of COVID-19 infection during the pandemic, compared with patients 1 year before the pandemic. METHODS: Observational study that included 138 consecutive patients hospitalized with STEMI who underwent primary percutaneous coronary intervention (PCI) without COVID-19 infection during the 2020 pandemic...

INTRODUCTION AND OBJECTIVES: After ST-segment myocardial infarction (STEMI), the impact of different adverse events on prognosis remains unknown. We aimed to assess very long-term predictors of patient-oriented composite endpoints (POCE) and investigate whether the occurrence of target vessel failure (TVF) vs a non-TVF event as the first event could potentially influence subsequent outcomes. METHODS: The EXAMINATION.EXTEND trial randomized STEMI patients to receive either an everolimus-eluting stent or a bare-metal stent...

We here describe the case of an 84-year-old woman with a history of ischemic heart disease, paroxysmal atrial fibrillation, and severe aortic stenosis, admitted to the coronary care unit of our hospital for an ST-elevation myocardial infarction secondary to in-stent thrombosis and treated with primary percutaneous coronary intervention. On admission, the patient was on chronic therapy with apixaban for atrial fibrillation, and reported no history of bleeding. However, the day after the administration of the loading doses of aspirin and clopidogrel, the patient developed multiple episodes of rectal bleeding and melena, requiring blood transfusions...

INTRODUCTION: Cerebral venous thrombosis is an uncommon cause of cerebrovascular disease, which has been increasing worldwide. In Colombia, there are not enough recent studies that allow us to determine epidemiological characteristics of the disease in our population to identify more frequent risk factors and complications according to our living conditions. OBJETIVE: To describe clinical, demographic, and radiographic characteristics, and risk factors in a cohort of patients with cerebral venous thrombosis attended at two hospitals in Colombia...
