Diagnostic accuracy of artificial-intelligence-based electrocardiogram algorithm to estimate heart failure with reduced ejection fraction: a systematic review and meta-analysis

Curr. probl. cardiol; 50 (4), 2025
INTRODUCTION: AI-based ECG has shown good accuracy in diagnosing heart failure. However, due to the heterogeneity of studies regarding cutoff points, its precision for specifically detecting heart failure with left ventricle reduced ejection fraction (LVEF <40 %) is not yet well established. What is the ...

Lung ultrasound performance in predicting cardiovascular outcomes for patients with STEMI: a systematic review and meta-analysis

BACKGROUND: Lung ultrasound (LUS) is a valuable, non-invasive tool for detecting pulmonary congestion in patients with acute heart failure (AHF), with a higher sensitivity relative to physical examination. However, the association between LUS-detected pulmonary congestion and cardiovascular outcomes in p...

The role of cardiac magnetic resonance in the diagnosis of left ventricular anterior wall pseudoaneurysm after myocardial infarction: A case report

DESCRIPTION OF CLINICAL PRESENTATION: A 47-year-old man with a history of hypertension presented to the emergency department with reports of dyspnea on mild exertion, tachycardic palpitations, bendopnea, and mild lower limb edema. Eight weeks prior to hospital admission, he experienced intense precordial...

Discontinuation vs continuation of renin-angiotensin system inhibition before non-cardiac surgery: a systematic review and meta-analysis

Circulation; 150 (Suppl. 1), 2024
BACKGROUND: The optimal management of angiotensin-converting enzyme (ACE) inhibitors during elective surgeries remains uncertain. While some studies suggest that continuing ACE inhibitors increase the risk of perioperative hypotension, others argue that discontinuation may heighten the risk of significan...

Atorvastatin therapy for prevention of anthracycline-induced cardiotoxicity in cancer patients: a meta-analysis

Circulation; 150 (Suppl. 1), 2024
INTRODUCTION: Cancer therapy-induced cardiac dysfunction is a significant adverse effect of chemotherapeutic agents, particularly anthracyclines (ANT). High-potency statin therapy, such as atorvastatin, appears to exert a protective effect against this condition. OBJECTIVE: We aimed to perform a meta-ana...

SGLT2 Inhibitors following acute myocardial infarction: a systematic review and meta-analysis

Circulation; 150 (Suppl. 1), 2024
BACKGROUND: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have demonstrated cardiovascular benefits in various settings. However, their impact after myocardial infarction (MI) in patients without prior heart failure remains unclear. Therefore, we conducted a meta-analysis comparing SGLT2i to placebo...

Diagnostic accuracy of artificial intelligence-based electrocardiogram algorithm to predict heart failure with reduced ejection fraction: a systematic review and meta-analysis

Circulation; 150 (Suppl. 1), 2024
INTRODUCTION: AI-based EKG has shown good accuracy for diagnosing heart failure. However, due to the heterogeneity of studies regarding cutoff points, its precision for specifically detecting heart failure with reduced ejection fraction (LVEF <40%) is not yet well established. Research question: What it ...

Identifying the impact of systolic dysfunction on CKD risk in HFpEF patients

Circulation; 150 (Suppl. 1), 2024
INTRODUCTION: Chronic kidney disease (CKD) is a critical comorbidity in heart failure with preserved ejection fraction (HFpEF), often linked to congestion due to elevated filling pressures. However, the role of subtle systolic dysfunction in CKD remains to be elucidated. This study aimed to investigate t...

Uso de beta-bloqueadores com dobutamina em pacientes com insuficiência cardíaca avançada em fila de transplante cardíaco: um estudo observacional
Use of beta-blockers with dobutamine in patients with advanced heart failure on a heart transplant waiting list: an observational study

Int. j. cardiovasc. sci. (Impr.); 37 (suppl. 12), 2024
FUNDAMENTO: Devido à grande quantidade de receptores para transplante de coração (TxC) e a falta de doadores, a fila de espera mesmo em prioridade por dependência inotrópica pode ser longa. Os beta-bloqueadores (BB) são fármacos de primeira linha no tratamento da insuficiência cardíaca de fraç�...
