A Human Engineered Heart Tissue‐Derived Lipotoxic Diabetic Cardiomyopathy Model Revealed Early Benefits of Empagliflozin

Advanced Science, EarlyView.
This study develops a human engineered heart tissue‐derived model of diabetic cardiomyopathy that accurately replicates the dynamic changes in the structural, contractile, and electrophysiological properties of the myocardium. Furthermore, this model is used to confirm the direct protective effects of empagliflozin on the heart through an SGLT2 off ...

Diastolic And Systolic Right Ventricular Dysfunction Precedes Left Ventricular Dysfunction In Patients Paced From Right Ventricular Apex [PDF]

, 2006
Background: Cardiac dysfunction after right ventricular (RV) apical pacing is well known but its extent, time frame of appearance and individual effect on left ventricular (LV), RV systolic and diastolic parameters has not evaluated in a systematic ...

In Vivo Dynamic Coronary Arteries Blood Flow Imaging Based on Multi‐Cycle Phase Clustering Ultrafast Ultrasound

Advanced Science, EarlyView.
This study addresses a critical gap in ultrafast ultrasound cardiovascular flow imaging and introduces a transformative approach, Clustering Singular Value Decomposition (cSVD), which enables dynamic cardiovascular flow imaging throughout full cardiac cycle without motion correction and hyper‐fast imaging strategies.

Pacemaker Concepts and Terminology [PDF]

, 1971
Since the introduction of implantable cardiac pacing systems there have been marked advances in concept and design of the equipment available. Whereas intracardiac pacing is usually identified with A-V conduction disturbances, recently gained knowledge ...

An intracardiac electrogram model to bridge virtual hearts and implantable cardiac devices

, 2017
Virtual heart models have been proposed to enhance the safety of implantable cardiac devices through closed loop validation. To communicate with a virtual heart, devices have been driven by cardiac signals at specific sites.

Role of cardiac resynchronization therapy in the development of new-onset atrial fibrillation: A single-center prospective study. [PDF]

, 2012
Albeit several studies examined the association between cardiac resynchronization therapy (CRT) and atrial fibrillation (AF) in heart failure (HF), results are still unclear and quite conflicting.

Superelastic Fire‐Safe Aerogel with Hierarchical Structures via Dual Templates Aided by Microbubble Engineering

Advanced Science, EarlyView.
Here, a dual‐template strategy (ice and bubble template) is used to prepare fire‐safe aerogels with hierarchical structures. When the foam expansion ratio exceeds the jamming transition value in the foam system, the aerogels demonstrate superelasticity and extreme shape adaptability.
