Tirzepatide and Cardiovascular Outcomes: A Narrative Review of Mechanisms, Efficacy and Implications for Heart Failure Management

open access: yesEndocrinology, Diabetes &Metabolism, Volume 9, Issue 1, January 2026.
Integrated framework for tirzepatide in HFpEF management. Through metabolic, haemodynamic, structural and anti‐inflammatory pathways, tirzepatide modifies the disease trajectory of HFpEF, leading to improvements in symptoms, functional capacity and reduction in HF events.

What have we learned from two-pore potassium channels? Their molecular configuration and function in the human heart [PDF]

open access: yes, 2012
Two-pore domain potassium channels (K2P) control excitability, stabilize the resting membrane potential below firing threshold, and accelerate repolarisation in different cells.

Age-dependent electrocardiographic changes in Pgc-1β deficient murine hearts. [PDF]

open access: yes, 2018
Increasing evidence implicates chronic energetic dysfunction in human cardiac arrhythmias. Mitochondrial impairment through Pgc-1β knockout is known to produce a murine arrhythmic phenotype.

Energy Metabolism Under Stress: Late‐Stage Leigh Syndrome Reveals Profound Cardiometabolic Perturbations in Ndufs4 KO Mice

open access: yesJournal of Inherited Metabolic Disease, Volume 49, Issue 1, January 2026.
Cardiac bioenergetic and metabolic perturbations in late‐stage Leigh syndrome. Whole‐body NDUFS4 loss severely impairs cardiac complex I activity and respiration, shifting reliance to complex II and reducing glycolytic, TCA, and amino acid‐derived energy‐generating substrates in the heart.

Subcutaneous nerve activity is more accurate than heart rate variability in estimating cardiac sympathetic tone in ambulatory dogs with myocardial infarction [PDF]

open access: yes, 2015
BACKGROUND: We recently reported that subcutaneous nerve activity (SCNA) can be used to estimate sympathetic tone. OBJECTIVE: The purpose of this study was to test the hypothesis that left thoracic SCNA is more accurate than heart rate variability (HRV)

Generation of an iPSC cell line (VANYHHi001-A) from a patient with cardiac arrythmias carrying CACNA1D, SCN5A, and DSP variants

open access: yesStem Cell Research
Progressive cardiac conduction defect often associated with variants in sodium voltage-gated channel SCN5A gene and variants in the L-type calcium voltage-gated channel CACNA1D gene are implicated in sinoatrial node dysfunction.

Role of sinoatrial node architecture in maintaining a balanced source-sink relationship and synchronous cardiac pacemaking

open access: yesFrontiers in Physiology, 2014
Normal heart rhythm (sinus rhythm) depends on regular activity of the sinoatrial node (SAN), a heterogeneous collection of specialized myocytes in the right atrium.

Electrophysiological properties of myocytes isolated from the mouse atrioventricular node:L-type ICa, IKr, If, and Na-Ca exchange [PDF]

open access: yes, 2015
The atrioventricular node (AVN) is a key component of the cardiac pacemaker-conduction system. This study investigated the electrophysiology of cells isolated from the AVN region of adult mouse hearts, and compared murine ionic current magnitude with ...

Use of antiarrhythmic drugs in elderly patients [PDF]

open access: yes, 2013
Human aging is a global issue with important implications for current and future incidence and prevalence of health conditions and disability. Cardiac arrhythmias, including atrial fibrillation, sudden cardiac death, and bradycardia requiring pacemaker ...
