Myocardial ATP depletion detected noninvasively predicts sudden cardiac death risk in heart failure patients.

JCI Insight 2022 May 17. Epub 2022 May 17.

Department of Medicine, Johns Hopkins University School of Medicine, Baltimore, United States of America.

Background: Sudden cardiac death (SCD) remains a worldwide public health problem in need of better noninvasive predictive tools. Current guidelines for primary preventive SCD therapies such as implantable cardioverter defibrillators (ICDs) are based on left ventricular ejection fraction (LVEF), but these are imprecise with fewer than 5% of ICDs delivering life-saving therapy per year. Impaired cardiac metabolism and ATP depletion cause arrhythmias in experimental models, but a link between arrhythmias and cardiac energetic abnormalities in people has not been explored, nor the potential for metabolically predicting clinical SCD risk.

Head-to-head comparison between recommendations by the ESC and ACC/AHA/HFSA Heart Failure Guidelines.

Eur J Heart Fail 2022 May 17. Epub 2022 May 17.

University of Warwick, Coventry, UK.

Recommendations represent the core messages of Guidelines, and are particularly important when the body of scientific evidence is rapidly growing, as in the case of heart failure (HF). The main messages from two latest major HF Guidelines, endorsed by the European Society of Cardiology (ESC) and the American College of Cardiology/American Heart Association/Heart Failure Society of America (ACC/AHA/HFSA), are partially overlapping, starting from the four pillars of treatment for HF with reduced ejection fraction. Some notable differences exist, in part related to the timing of recent publications (most notably, the Universal Definition of Heart Failure paper and the EMPEROR-Preserved trial), and in part reflecting differing views of the natural history of HF (with a clear differentiation between stages A and B HF in the ACC/AHA/HFSA Guidelines).
