Pentoxyphylline: possibilities to reduce manifestations of chronic heart failure with preserved left ventricular ejection fraction in elderly by V. B. Shatylo, L. A. Bodretska, I. S. Shapovalenko, H. P. Voinarovska, Zh. S. Butynets

“…The addition of pentoxifylline to the standard therapy in patients with chronic heart failure with preserved left ventricular ejection fraction significantly reduces myocardial hypertrophy, improves diastolic relaxation, increases volumetric blood flow velocity in microvessels mediating reactive hyperemia, which may contribute to further stabilizing the clinical course of the disease and increasing 6-minute walking distance. …”

Incidence of Rapid Rate Non‐Sustained and Sustained Ventricular Tachycardia in Implantable Cardioverter‐Defibrillator Recipients and Its Correlation With Heart Failure Guideline‐Di... by Muhammad Taha Khan, Ghazala Irfan, Sarim Ansari, Zubair Mumtaz, Faisal Qadir, Azam Shafquat

“…ABSTRACT Background Ventricular arrhythmias are prevalent among heart failure with reduced ejection fraction (HFrEF) patients. Rapid rate non‐sustained ventricular tachycardia (RR‐NSVT) and sustained ventricular tachycardia (VT) can be detected on implantable cardioverter‐defibrillator (ICD) interrogation due to discrimination algorithms that differentiate supra‐ventricular from ventricular tachycardia. …”

Electrocardiographic signs of impaired depolarization (fragmented QRS, early ventricular repolarization, etc.) as markers of left ventricular systolic dysfunction by M. S. Gordeeva, I. A. Serdiukova, A. S. Krasichkov, E. V. Parmon

“…To study the relationship between a decrease in left ventricular (LV) ejection fraction (EF) and conventional electrocardiographic (ECG) signs associated with myocardial structure changes (pathological Q wave, ventricular arrhythmias), and relatively novel and less studied (fragmented QRS (fQRS), early ventricular repolarization (EVR)) and to evaluate their significance for identifying patients with mildly-reduced EF (mrEF).Material and methods. …”

Persistent Fibrosis in Heart Failure With a Reduced Ejection Fraction Linked to Phenotypic Differences in Human Cardiac Fibroblast Populations by Rachel M. Biggs, Yuhua Zhang, Daniel N. Silverman, Catalin F. Baicu, An O. Van Laer, Lauren Wakefield, Devki Bhatt, Stephanie Masline, Lily S. Neff, Arman Kilic, Lucas J. Witer, Brian A. Houston, Samuel J. Coeyman, William J. Richardson, Michael R. Zile, Amy D. Bradshaw

“…Background Myocardial fibrosis is prevalent in cardiomyopathies that result in heart failure with reduced ejection fraction. Heart failure with reduced ejection fraction treated with a left ventricular assist device (LVAD) yields hemodynamic unloading and may provide partial cardiomyocyte recovery, but contemporary studies reveal no consistent reductions in fibrosis. …”
