Dear editor, The study published by Tang et al., entitled “Factors Affecting False Lumen Thrombosis in Type B Aortic Dissection,” highlighted the influence of morphological aspects of type B aortic dissection (TBAD), according to the Stanford classification, on false lumen thrombosis prior to treatment with endovascular repair of the thoracic aorta. It has been shown that false lumen thrombosis occurs significantly less frequently in patients with TBAD and renal failure, when compared with those with TBAD and normal renal function. […]

To Editor The early detection of asymptomatic atrial fibrillation (AF) is considered essential for preventing thromboembolic events and the progression of heart failure. Numerous wearable devices have been developed to facilitate this objective. The authors employed stroke risk analysis (SRA), a method that stratifies the risk of paroxysmal AF through the evaluation of electrocardiogram data. This algorithm proved effective in screening patients with asymptomatic paroxysmal AF, with 29.4% of participants categorized as high-risk. Among these high-risk individuals, AF was detected […]

To the Editor, We read with great interest the article by Ternes et al., recently published in the Arquivos Brasileiros de Cardiologia, with its accompanying insightful editorial., This multicentre prospective cohort study of consecutive patients across three centres in Brazil provided valuable insights into the predictors of atrial arrhythmia recurrence following first-time catheter ablation. It highlighted its clinical setting in a middle-income country and reported outcomes similar to those in high-income countries. However, the results must be interpreted cautiously, and […]

To the editor Anticoagulation is a standard therapeutic approach for patients with atrial fibrillation (AF), requiring careful consideration of the balance between antithrombotic efficacy and the risk of hemorrhagic complications. The authors examined the rate of anticoagulant prescriptions among patients admitted to the emergency department with symptomatic AF, revealing a higher prevalence of non-prescription in women compared to men. This observation raises several important concerns. […]

To editor The identification of an optimal modality to monitor the severity of pulmonary arterial hypertension (PAH) remains imperative. The authors demonstrated that a prolonged RS interval on the electrocardiogram was associated with adverse clinical outcomes in this cohort, under the hypothesis that right heart electrical conduction is compromised in patients with severe PAH. Nonetheless, several concerns merit consideration. […]

Dear Editor, We read with great interest the article by Carvalho et al. titled “Potentially Inappropriate Cardioverter Defibrillator Implants in Secondary Prevention of Death”, which highlights the critical role of socioeconomic and psychosocial markers (EPSM) in predicting early mortality post-implantable cardioverter defibrillator (ICD) implantation. While the study provides valuable insights into multidisciplinary team (MDT) assessments, we would like to address two significant limitations that could refine future research and clinical practice. […]

To Editor The ablation of atrioventricular nodal reentrant tachycardia (AVNRT) using cryoablation has emerged as a viable alternative to radiofrequency (RF) ablation due to its reduced risk of inducing permanent atrioventricular block. However, this technique necessitates specific procedural considerations to minimize the recurrence of arrhythmias. The authors conducted a comparative analysis of clinical outcomes between cryoablation and conventional RF ablation, demonstrating that cryoablation was associated with reduced fluoroscopy time and was non-inferior to RF ablation in terms of efficacy and […]

To Editor Accurate assessment of pulmonary congestion is pivotal for the optimal management of congestive heart failure. The remote dielectric sensing (ReDS) system represents a recently developed non-invasive technology designed to quantify lung fluid volume without requiring specialized expertise. Kobalava et al. demonstrated a moderate correlation between the ReDS system and lung ultrasound. However, several concerns warrant further discussion. […]

Coronary artery disease, a cardiovascular disease in which there is obstruction of blood flow in the myocardial vessels, causes a large number of deaths in Brazil every year. Myocardial revascularization surgery, associated with antiplatelet, lipid-lowering, and RAAS blocker medications, is the best option for treating and preventing new cases of vascular flow obstruction, thus allowing the restoration of ventricular function, reduction of angina and prevention of acute myocardial infarction. Thus, it has clinical and surgical importance, as it allows the […]

I read with interest the paper “Resting Heart Rate Variability is Independently Associated with Visceral Fat Rating Scores in Saudi Adult Males” by Syed Shahid Habib et al., published in ABC Cardiolcomparing heart rate variability (HRV) in 99 healthy men stratified by visceral fat rating (VFR) and showing associations between HRV and body composition metrics, but I have some reservations. Heart rate variability has been demonstrated as a convenient method for assessing individual homeostatic status. Attempts to establish reference values […]
