Article Synopsis
- This study looks at how well doctors can predict sudden cardiac death after someone has a heart attack using a measurement called left ventricular ejection fraction (LVEF).
- They combined information from over 140,000 heart attack patients to see if LVEF alone is good enough for deciding who should get a heart device called a defibrillator.
- The results showed that LVEF didn't do a great job at predicting sudden cardiac death, which means doctors need better ways to tell who is at risk.
Heart failure and chronic kidney disease are common and clinically important conditions that regularly coexist. Electrophysiologic changes of advanced heart failure often result in abnormal conduction, causing dyssynchronous contraction, and development of ventricular arrhythmias, which can lead to sudden cardiac arrest. In the last 2 decades, implantable cardioverter-defibrillator and cardiac resynchronization therapy devices have been developed to address these complications.

Objectives: This study sought to determine whether total myocardial fibrosis (TF) and gray zone fibrosis (GZF), assessed using cardiovascular magnetic resonance, are better than left ventricular ejection fraction (LVEF) in predicting ventricular arrhythmias in patients with nonischemic cardiomyopathy (NICM).
Methods: Patients with NICM in a derivation cohort (n = 866) and a validation cohort (n = 848) underwent quantification of TF and GZF.
Aims: The accomplishment of value-based healthcare (VBHC) models could save up to $1 trillion per year for healthcare systems worldwide while improving patients' wellbeing and experience. Nevertheless, its adoption and development are challenging. This review aims to provide an overview of current literature pertaining to the implementation of VBHC models used in cardiology, with a focus on cardiac electrophysiology.

This systematic review and meta-analysis analyses the current evidence on clinical outcomes in SDD after AF ablation compared with overnight stay (ONS).
Methods And Results: A systematic search of the PubMed database was performed.
