Ablação de FA combinada com ablação de septo por radiofrequência: a importância do substrato estrutural
AF ablation combined with radiofrequency septum ablation: the importance of the structural substrate

INTRODUÇÃO. A cardiomiopatia hipertrófica (CMH) pode apesentar, como consequência de alterações estruturais e fisiopatológicas dessa prevalente cardiopatia, a fibrilação atrial (FA) e a obstrução de via de saída de ventrículo esquerdo (VSVE), conferindo maior morbimortalidade ao paciente. As...

Variations in the prevalence of atrial fibrillation, and in the strength of its association with ischemic stroke, in countries with different income levels: INTERSTROKE case-control study

Int. j. stroke; (), 2024
BACKGROUND: The contribution of atrial fibrillation (AF) to the etiology and burden of stroke may vary by country income level. AIMS: We examined differences in the prevalence of AF and described variations in the magnitude of the association between AF and ischemic stroke by country income level. METHOD...

Investigação do tratamento da FA reumática com antagonistas da vitamina K, Rivaroxabana ou Aspirina - estudo invictus
Investigation of rheumatic af treatment using vitamin K antagonists,Rivaroxaban or Aspirin studies - invictus trial

A doença cardíaca reumática (DCR) é endêmica em países em desenvolvimento.Os estudos com anticoagulantes de ação direta (direct-acting oral anticoagulants — DOAC) para a prevenção de eventos cardiovasculares em pacientes com fibrilação atrial (FA) associada a DCR têm sido limitados. O estu...

Apixabana para prevenção de acidente vascular cerebral na fibrilação atrial subclínica – estudo artesia
Apixaban for stroke prevention in subclinical atrial fibrillation – the artesia trial

A detecção de fibrilação atrial (FA) subclínica é um achado frequente em portadores de dispositivos cardíacos eletrônicos implantáveis e associa-se a um risco aumentado de acidente vascular cerebral (AVC). O estudo ARTESiA, publicado em 2023, teve como objetivo avaliar os efeitos da apixabana ne...

P-wave indices for risk assessment of atrial fibrillation in chagas disease

Arq. bras. cardiol; 120 (12 supl.1), 2023
BACKGROUND: Studies analyzing atrial activation in electrocardiograms (ECG) usually highlight P-wave duration, P-wave dispersion, PR interval, P/PRi ratio, and atrial activation time (AAT). Although these indices can be predictors of atrial fibrillation (AF) development in different clinical contexts, th...

Ablação septal combinada a ablação de FA: uma solução elegante na insuficiência mitral pelo SAM em obstrução grave da VSVE?
Septal ablation combined with AF ablation: an elegant solution in mitral insufficiency caused by SAM in severe LVOT obstruction?

Arq. bras. cardiol; 120 (12 supl.1), 2023
Paciente 67 anos, portadora de fibrilação atrial e cardiomiopatia hipertrófica obstrutiva, com paroxismos de fibrilação atrial sintomáticos, com redução de classe funcional e internações frequentes. Apresenta dispneia a pequenos esforços, evoluindo para dispneia em repouso quando em fibrilaçÃ...

Reduced left atrial strain and risk of ischemic stroke in patients with normal sinus rhythm: a systematic review and meta-analysis

Circulation; 148 (Suppl.1), 2023
INTRODUCTION: Abnormalities in the left atrium have been linked to a higher risk of ischemic cerebrovascular events. Left atrial (LA) strain analysis can identify LA dysfunction, even in patients with normal LA volumes. However, the precise association between LA strain and the occurrence of ischemic str...

Efficacy of sacubitril-valsartan compared with angiotensin-converting enzyme inhibitor or angiotensin-receptor blocker for preventing atrial fibrillation recurrence after catheter ablation: a systematic review and meta-analysis

Circulation; 148 (Suppl.1), 2023
INTRODUCTION: Among patients with atrial fibrillation (AF) who underwent catheter ablation, it is unclear whether AF recurrence is lower in those who receive Sacubitril-Valsartan (SV) than in those who receive ACEi (angiotensin-converting enzyme inhibitor) or ARB (angiotensin-receptor blocker). Hypothesi...

Enhancing predictive accuracy of H2FPEF score in suspected HFpEF by incorporating left atrial reservoir strain

Circulation; 148 (Suppl.1), 2023
INTRODUCTION: Diagnosing HFpEF can be challenging, but the H2FPEF score is a valuable tool for clinical decision-making. Atrial fibrillation (AF) plays a significant role in this score, creating challenges for diagnosis in patients without AF or with paroxysmal AF. Left atrial reservoir strain (LArS) has...

Leveraging advanced ai algorithms for predicting outcomes in non-acute coronary syndrome chest pain patients

Circulation; 148 (Suppl.1), 2023
INTRODUCTION: Chest pain is often encountered in emergency rooms and the detection of acute coronary syndrome (ACS) is a major focus. However, a notable percentage of patients present with a diverse range of nonACS conditions. Accurately identifying the causes and outcomes of these cases can prevent unne...
