Strain Rate Angle Distribution as an Indicator of Post‐Infarct Myocardial Remodeling: Proof‐of‐Concept of a Novel Application of the MRI Derived Strain Rate Tensor Field

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Left ventricular (LV) strain is an early indicator of myocardial dysfunction. However, conventional strain metrics do not fully account for the multidirectional nature of myocardial deformation. The strain rate tensor, derived from velocity‐encoded MRI, represents the time‐resolved magnitude and direction of strain rate without the ...

Rotating Frame Spin‐Lock Cardiac MRI Method at 9.4 T Can Characterize Diffuse Fibrosis in Progressing Hypertensive Heart Disease in Mice

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study aimed to investigate the applicability of rotating frame spin‐lock continuous wave (CW) T1ρ and relaxation along a fictitious field with Rank 2 (RAFF2) methods complementary to native T1 and late gadolinium enhancement (LGE) for cardiac magnetic resonance imaging (CMRI) of diffuse fibrosis in mice with advancing hypertensive

Role of Dobutamine Stress Test and Speckle Tracking in Ischemic Heart Disease, Comparative Study

Medical Journal of Babylon
Background:Coronary artery disease (CAD) is a major cause of cardiovascular mortality. Echocardiography plays a vital role in early detection and treatment. Objectives:We investigated the use of speckle tracking during dobutamine stress echocardiography (

Gentiopicroside Regulates EGFR and Induces Its Lysosomal Degradation to Attenuate Heart Failure

Phytotherapy Research, EarlyView.
GPS attenuates pressure overload‐induced cardiac remodeling by promoting lysosomal degradation of EGFR. TAC‐induced EGFR accumulation activates AKT/ERK1/2 signaling and drives pathological cardiac hypertrophy, fibrosis, apoptosis, oxidative stress, and cardiac dysfunction. GPS promotes lysosome‐dependent EGFR degradation, thereby limiting excessive AKT/

Cardiomyocyte Membrane‐Camouflaged Spinach Nano‐Thylakoids Enhance Myocardial Energy Metabolism and Ameliorate Heart Failure

Small, EarlyView.
Schematic illustration of the construction of MM‐NTU, its cardiac‐targeting behavior, and its light‐activated therapeutic mechanism. Thylakoids isolated from spinach chloroplasts were processed into nano‐thylakoid units (NTU) and further camouflaged with cardiomyocyte membranes to generate MM‐NTU.

Isolated complete right bundle branch block – findings in the interventricular septum with the speckle-tracking echocardiography: a case report

Heart Vessels and Transplantation
Objective: Isolated complete right bundle branch block (CRBBB) is a known ECG finding in apparently healthy adults. However, the etiology of CRBBB is studied poorly and its prognosis still debatable.

Circulating Musclin is associated with skeletal muscle function and subclinical cardiac dysfunction in patients with cancer

British Journal of Pharmacology, EarlyView.
Background and Purpose Musclin (osteocrin) is a skeletal muscle‐derived peptide that has been implicated in cardioprotective signalling pathways. Its relevance in cancer patients, who frequently experience muscle wasting and cardiotoxicity, remains unclear. This study aimed to determine whether circulating Musclin levels reflect functional capacity and

Cardiac structure and function in psoriasis: A cross‐sectional analysis of the PSOCADIA study

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Individuals with well‐treated psoriasis exhibited a higher burden of myocardial dysfunction (GLS < 16%) compared with controls, independent of cardiometabolic comorbidity. The prevalence was similar across psoriasis severity, highlighting the importance of cardiovascular assessment in all patients with psoriasis. Abstract Background Psoriasis is linked
