Etiology-Specific Remodeling in Ventricular Tissue of Heart Failure Patients and Its Implications for Computational Modeling of Electrical Conduction.

Frontiers in physiology

Front Physiol. 2021 Oct 05;12:730933. doi: 10.3389/fphys.2021.730933. eCollection 2021.

With an estimated 64.3 million cases worldwide, heart failure (HF) imposes an enormous burden on healthcare systems. Sudden death from arrhythmia is the major cause of mortality in HF patients. Computational modeling of the failing heart provides insights into...

Remodeling of t-system and proteins underlying excitation-contraction coupling in aging versus failing human heart.

NPJ aging and mechanisms of disease

Lyu Y, Verma VK, Lee Y, Taleb I, Badolia R, Shankar TS, Kyriakopoulos CP, Selzman CH, Caine W, Alharethi R, Navankasattusas S, Seidel T, Drakos SG, Sachse FB.

NPJ Aging Mech Dis. 2021 May 28;7(1):16. doi: 10.1038/s41514-021-00066-7.

It is well established that the aging heart progressively remodels towards a senescent phenotype, but alterations of cellular microstructure and their differences to chronic heart failure (HF) associated remodeling remain ill-defined. Here, we show that the transverse tubular system...

The pyruvate-lactate axis modulates cardiac hypertrophy and heart failure.

Cell metabolism

The metabolic rewiring of cardiomyocytes is a widely accepted hallmark of heart failure (HF). These metabolic changes include a decrease in mitochondrial pyruvate oxidation and an increased export of lactate. We identify the mitochondrial pyruvate carrier (MPC) and the...
