Ultrasound study of right ventricular myocardial perfusion and functional changes in hypertrophic cardiomyopathy

BMC Cardiovascular Disorders
Background To evaluate the changes of right ventricular (RV) myocardial perfusion and function in patients with hypertrophic cardiomyopathy (HCM) by myocardial contrast echocardiography (MCE) and speckle tracking (2D-STE), and to explore the relationship

Imaging Techniques for the Assessment of Myocardial Perfusion

Journal of Interdisciplinary Medicine, 2016
One of the most significant causes of heart failure is coronary heart disease and subsequent left ventricular dysfunction. The prognosis and perioperative mortality are influenced by left ventricular function, which is also an important predictor marker ...

SerpinA3 is an Endogenous TGF‐β Receptor Antagonist that Attenuates Cardiac Fibroblast Activation and Fibrotic Remodeling

Advanced Science, EarlyView.
SerpinA3 acts as an endogenous TGF‐β receptor antagonist that binds to the extracellular domain of TGFR‐1, thereby preventing TGFR‐1–TGFR‐2 complex formation. This receptor‐level blockade suppresses TGF‐β/Smad2/3 signaling, attenuates cardiac fibroblast activation, and extracellular matrix deposition, and ultimately alleviates pressure overload–induced

THSD7A Exacerbates Atherosclerosis via Activation of Signaling Axis αvβ3/CEBPD/IL1A

Advanced Science, EarlyView.
THSD7A exerts pro‐inflammatory effects and exacerbates atherosclerosis. Mechanistically, THSD7A regulates endothelial cell inflammation and atherosclerosis by activating the αvβ3/CEBPD/IL1A signaling axis. THSD7A is not only a genetic marker but also a potential therapeutic target for coronary artery disease (CAD).

Computed tomographic myocardial mass compared with invasive myocardial perfusion measurement

, 2020
OBJECTIVE: The prognostic importance of a coronary stenosis depends on its functional severity and its depending myocardial mass. Functional severity can be assessed by fractional flow reserve (FFR), estimated non-invasively by a specific validated CT ...

Visualization of Minute Mechanical-Excitation/Relaxation Wave-front Propagation in Myocardial Tissue [PDF]

, 2010
Unlike the case of skeletal muscle, the direction of myocardial contraction does not coincide with the direction of work necessary to eject the intraventricular blood, contributing to great complexity of the wall deformation sequence of cardiac ...

Periostin‐CCL3 Feedforward Signaling Loop Promotes Cardiac Fibrosis and Cardiomyocyte Necroptosis in Arrhythmogenic Cardiomyopathy

Advanced Science, EarlyView.
POSTN‐CCL3 signaling forms a feed‐forward circuit between cardiomyocytes and cardiac myofibroblasts in arrhythmogenic cardiomyopathy. POSTN activates JNK/RIP3‐dependent necroptotic signaling and JNK/ETS2‐induced CCL3 expression in cardiomyocytes. In turn, CCL3‐CCR5 signaling in cardiac myofibroblasts activates NF‐κB/p65 and promotes POSTN expression ...

Perioperative myocardial perfusion

Current Opinion in Anaesthesiology, 2015
Cardiac complication following noncardiac surgery is the leading cause of death in the perioperative period. Disturbances in myocardial perfusion are at the basis of these complications. The purpose of this review was to summarize the most recent findings on factors affecting myocardial perfusion in the perioperative period and possibilities for ...

Attenuation correction of myocardial perfusion scintigraphy images without transmission scanning [PDF]

, 2015
Attenuation correction is essential for reliable interpretation of emission tomography; however the use of transmission measurements to generate attenuation maps is limited by availability of equipment and potential mismatches between the transmission ...
