Article Abstract
This study proposes a method for ventricular late potentials (VLPs) detection using time-frequency representation and wavelet denoising in high-resolution electrocardiography (HRECG). The analysis is performed both with the signal averaged electrocardiography (SAECG) and in real time. A comparison between the temporal and the time-frequency analysis is also reported. In the first analysis the standard parameters QRSd, LAS40, and RMS40 were used; in the second normalized energy in time-frequency domain was calculated. The algorithm was tested adding artificial VLPs to real ECGs.

Medizinische Klinik und Poliklinik II, Universitätsklinikum Bonn, Venusberg-Campus 1, Bonn 53127, Germany.
Background And Aims: Fulminant myocarditis (FM) is a complex clinical syndrome characterized by acute myocardial inflammation and cardiogenic shock. Evidence on long-term outcomes, mortality risk factors, and targeted treatment options remains limited.
Methods: This retrospective analysis included consecutive adult patients admitted for FM between January 2012 and November 2022 at 26 European tertiary centres.

Department of Cardiology, The Ninth Medical Center, Chinese PLA General Hospital.
Background Hyperuricemia (HUA) frequently coexists with coronary artery disease (CAD) and is linked to adverse cardiovascular outcomes. The long-term impact of urate-lowering therapy (ULT) on clinical outcomes, including all-cause mortality and major adverse cardiovascular events (MACEs), in CAD patients after percutaneous coronary intervention (PCI) has not been determined. That was the aim of this study.

Material and methods The study included 150 cancer patients with a high and very high Mayo Clinic (USA) Cardiotoxicity Risk Score. The main group consisted of 84 patients at high and very high risk of cardiotoxicity who were prescribed cardioprotective therapy, including a fixed combination of the angiotensin-converting enzyme inhibitor (ACEI) perindopril and the beta-blocker bisoprolol with trimetazidine.
