Association between left ventricular reverse remodelling and the B-type natriuretic peptide-cGMP cascade after anterior acute myocardial infarction.
Open Heart
January 2025
Department of Cardiovascular Medicine, National Cerebral and Cardiovascular Center, Suita, Osaka, Japan.
Background: The role of cyclic guanosine 3',5'-monophosphate (cGMP) after acute myocardial infarction (AMI) is not well understood despite its significance as a second messenger of natriuretic peptides (NPs) in cardiovascular disease. We investigated the association between the NP-cGMP cascade and left ventricular reverse remodelling (LVRR) in anterior AMI.
Methods: 67 patients with their first anterior AMI (median age, 64 years; male, 76%) underwent prospective evaluation of plasma concentrations of the molecular forms of A-type and B-type natriuretic peptide (BNP) and cGMP from immediately after primary percutaneous coronary intervention (PPCI) to 10 months post-AMI.
From Escalate to Elevate: A New Paradigm for Comprehensive Cardiogenic Shock Management.

Patients with cardiogenic shock (CS) present with critical hemodynamic compromise with low cardiac output (CO) resulting in end-organ dysfunction. Prognosis is closely related to the severity of shock and treatment of patients with CS is resource intensive. In this review, we consider the current treatment paradigms alongside the evidence that underpins them.

Arch Biochem Biophys
January 2025
Institute of Cell Biophysics RAS - a separate subdivision of Federal Research Centre "Pushchino Scientific Centre for Biological Research RAS", Institutskaya St., 3, 142290, Russia, Moscow Region, Pushchino. Electronic address:
The possibility of using an oxygen-nitrous oxide mixture for prolonged hypothermic preservation of rat heart for 24 hours was investigated. A comparative analysis of restoration of functional activity of hearts in the groups of 24-hour preservation at +4°C with different gases (O, N) and gas mixtures (CO+O, NO+O, N+O, NO+N) was carried out. It was shown that the presence of oxygen in the gas mixture was the key factor for heart preservation.

JACC Heart Fail
January 2025
The Zena and Michael A. Wiener Cardiovascular Institute, Icahn School of Medicine at Mount Sinai, New York, New York, USA.
Background: Left ventricular (LV) dilatation and extensive scar portend a poor prognosis in heart failure (HF). The Revivent TC system (BioVentrix Inc) is used either during a hybrid transcatheter-surgical or a surgical-only procedure to exclude transmural scar and reduce LV dimensions.
Objectives: The purpose of this study was to examine the safety and efficacy of the Revivent TC® anchor system in patients with HF.
Hypereosinophilic Syndrome Complicated by Eosinophilic Myocarditis: Embolic Stroke or Eosinophilic Stroke? A Case Report.
Turk Kardiyol Dern Ars
January 2025
Department of Cardiology, Isfahan University of Medical Sciences, Isfahan, Iran.
Hypereosinophilic syndrome (HES) is traditionally described as chronic peripheral eosinophilia with involvement of various organs and systems, including the heart and nervous system. In this report, we describe cardiac involvement and border zone stroke in a patient with idiopathic HES. A 37-year-old woman presented with sudden right-sided weakness and slurred speech, which began four days before admission, accompanied by palpitations, retrosternal exertional chest discomfort, dry cough, and progressive shortness of breath over approximately two months.
