Arritmias

INTRODUCTION AND OBJECTIVES: Idiopathic ventricular fibrillation (IVF) is diagnosed in patients who survive sudden cardiac arrest (SCA), preferably with documented ventricular fibrillation (VF), without any identifiable structural or electrical abnormality. Current evidence provides limited guidance on the diagnosis and follow-up of these patients. Our aim was to assess the clinical outcomes of survivors of an aborted SCA attributed to IVF. METHODS: We retrospectively collected clinical data from all patients who survived SCA and implanted a cardiac defibrillator (ICD) between 2005 and 2023...

describir un paciente con isquemia miocárdica con múltiples causas. Caso Clínico: En este caso clínico se describe a un hombre de 58 años con antecedentes de hipertensión, dislipidemia, EPOC e infarto de miocardio (IAM) previo. Acudió a urgencias con dolor torácico y disnea. Los hallazgos incluyeron crepitantes bibasales, electrocardiograma con fibrosis anterior antigua, NT-ProBNP elevado y ecocardiograma con acinesia septoapical. Durante la hospitalización, experimentó taquiarritmia y deterioro hemodinámico, siendo sometido a cardioversión eléctrica (CVE)...

BACKGROUND: The Tpe interval (Tp-e) in the surface electrocardiogram represents ventricular repolarization, a key phase in the pathogenesis of severe ventricular arrhythmias. However, there are few studies evaluating changes in this electrocardiographic interval as a risk factor for serious arrhythmias in patients with dilated cardiomyopathy. OBJECTIVE: To determine whether the Tp-e interval prolongation predicts the presence of life-threatening arrhythmias in patients with dilated cardiomyopathy (DCM) with implantable cardioverter-defibrillator (ICD)...

The need to improve access to health services for the transgender community has become evident, especially concerning cardiovascular risk, which is higher compared to the general population. Surgical procedures and hormone therapies are common in this population to affirm gender identity, but they pose challenges as they are associated with disruptions in lipid metabolism, body fat concentration, and insulin resistance. Additionally, there is an increased risk of adverse cardiovascular events such as venous thromboembolism, stroke, and myocardial infarction...

AIMS: To analyze the relationship between Mediterranean Diet (MedDiet) adherence and epicardial adipose tissue (EAT) in patients with atrial fibrillation (AF) and the association between EAT or MedDiet adherence at baseline with AF recurrence after ablation. METHODS: We included 199 patients from the PREDIMAR trial (PREvención con DIeta Mediterránea de Arritmias Recurrentes), in a single Center in this sub-study. All of them had a computed tomography with EAT measurement...

INTRODUCTION AND OBJECTIVES: Cardiovascular disease is a common cause of morbidity and mortality in pregnant women. Arrhythmias are common complications during pregnancy; however, the data are limited. Our goal was to characterize the epidemiology, clinical presentation, and impact of cardiac arrhythmias on maternal-fetal outcomes. METHODS: A prospective cohort study from the Colombian Registry of Pregnancy and Cardiovascular Disease was carried out from 2016 to 2019...

BACKGROUND AND OBJECTIVE: Systemic adverse effects (AE) are a major concern of low-dose oral minoxidil (LDOM) treatment, especially in patients with arterial hypertension or arrhythmia. The objective of this study was to evaluate the safety of LDOM in patients with hypertension or arrhythmia. PATIENTS AND METHODS: Retrospective multicenter study of patients with hypertension or arrhythmia treated with LDOM for any type of alopecia. RESULTS: A total of 254 patients with hypertension [176 women (69...

INTRODUCTION AND OBJECTIVES: This article presents results of the Spanish catheter ablation registry for the year 2022. METHODS: Data were retrospectively entered into a REDCap platform using a specific form. RESULTS: A total of 103 centers participated (75 public, 28 private), which reported 23 360 ablation procedures, with a mean of 227 ± 173 and a median of 202 [interquartile range, 77-312] procedures per center...

INTRODUCTION: Patients with SARS-CoV-2 infection may present cardiovascular involvement including myocarditis, arrhythmias and QT interval prolongation. Our objective was to evaluate the impact of COVID-19 and its treatment on ventricular repolarization and development of arrhythmias in critically ill patients. METHODS: Retrospective cohort study of critically ill COVID-19 patients during a 3-month period in whom at least one ECG was available. Relevant clinical data and specific treatment administered for COVID-19 were recorded...

OBJECTIVE: To describe the quality of life in patients with idiopathic ventricular arrhythmias treated at the Instituto Nacional Cardiovascular INCOR in Lima -Peru. MATERIALS AND METHODS: . Analytical and cross-sectional study of patients with idiopathic ventricular arrhythmias treated by 3D ablation or antiarrhythmic therapy between July 2017 and December 2019 to whom the SF-36 health questionnaire was applied to assess quality of life related to health. RESULTS: Fifty-two patients with idiopathic ventricular arrhythmias were included (34 underwent 3D ablation, and 18 underwent antiarrhythmic therapy only)...

OBJECTIVES: This study sought to evaluate the incidence, prognosis and treatment of heart rhythm disorders (HRD) in Tako-tsubo syndrome (TTS). BACKGROUND: TTS is associated with HRD. The HRD prognostic value is not well characterized in TTS yet. METHODS: The HRD of patients included in the National Registry of Tako-tsubo syndrome, admitted between 2002 and 2018 and coming from 38 hospitals throughout the country, was analyzed. We analyzed any heart rhythm disorder in patients presented before admission, at admission and in long-term follow-up...

INTRODUCTION: Myotubular myopathy is a congenital muscle disease caused by a mutation in the myotubularin (MTM1) gene. The X-linked myotubular myopathy (XLMTM) affects males with early-onset symptoms such as muscle weakness, hypotonia, and respiratory distress. To our knowledge, cardiac involvement has not been previously described in this condition, in contrast to other types of congenital myopathies such as nemaline myopathy or core myopathy. CASE REPORTS: We report two clinical cases of XLMTM that started with severe sinus bradycardia or auriculoventricular block from the first days of life, with pathologic 24-hours Holter monitoring in both cases...

OBJECTIVES: Patients with implantable cardioverter defibrillators (ICDs) are at risk of serious complications that are often treated in hospital emergency departments (EDs). The EMERG-ICD study (Emergency Department Management and Long-term Prognosis for Patients with ICDs) analysed management and long-term prognosis of ED patients with an ICD after an acute clinical event. MATERIAL AND METHODS: Observational multicenter cohort study including consecutive adult patients with ICDs who came to 27 hospital EDs in Spain for treatment and were followed for 10 years...

In Portugal, up to 38% of the population has cardiovascular disease, which highlights the importance of primary health care (PHC) in its management. Adequate management of people with cardiovascular disease often requires hospital referral for a cardiology consultation. However, it is not always easy to ascertain which situations should be referred, especially given that PHC does not have access to all diagnostic exams recommended by international guidelines, such as natriuretic peptides in heart failure or computed tomography coronary angiogram in chronic coronary syndromes, among others...

BACKGROUND: Cardiac magnetic resonance (CMR) has an increasing diagnostic relevance in survivors of sudden cardiac death (SCD) or unstable ventricular arrhythmia (UVA) in developed countries. OBJECTIVE: To evaluate retrospectively the additional role of CMR in a developing country where few resources are available, and should be used more effectively. METHODS: The study included SCD or UVA survivors admitted between 2009 and 2019 at a tertiary academic institution referred to CMR...

INTRODUCTION AND AIMS: Cardiac involvement in systemic sclerosis (SS) is frequently silent and a major cause of mortality in these patients. This work aims to study the prevalence and associations of left ventricular dysfunction (LVD) and arrhythmias in SS. METHODS AND RESULTS: Prospective study of SS patients (n=36), excluding those with symptoms of (or) cardiac disease, pulmonary arterial hypertension or cardiovascular risk factors (CVRF). A clinical, analytical, electrocardiogram (EKG), Holter, and echocardiogram with global longitudinal strain (GLS) assessment were performed...
