Agreement between cardiac cycle time intervals and myocardial velocities measured by automated analysis of color tissue Doppler cine loops and by manual tracing of spectral pulsed‐wave tissue Doppler waveforms of sheep fetal heart under normal and pathological conditions: An experimental study

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Automated cTDI in sheep fetuses provided reproducible measurements of myocardial velocities and heart rate that align well with manual pulsed‐wave TDI. For cardiac cycle duration metrics, the two modalities are not interchangeable. These findings support that automated cTDI is well suited for longitudinal assessment under both physiological and ...

X-ray Multimodal Intrinsic-Speckle-Tracking

, 2019
We develop X-ray Multi-modal Intrinsic-Speckle-Tracking (MIST), a form of X-ray speckle-tracking that is able to recover both the position-dependent phase shift and the position-dependent small-angle X-ray scattering (SAXS) signal of a phase object. MIST

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

Speckle Tracking and Transthyretin Amyloid Cardiomyopathy

Arquivos Brasileiros de Cardiologia
Background: Amyloidosis is a disease caused by deposits of insoluble fibrils in extracellular spaces. The most common type of familial amyloidosis is mediated by mutation of transthyretin, especially Val30Met.

Speckle tracking echocardiography data in Brugada syndrome patients

Data in Brief, 2019
Brugada syndrome is characterized by typical electrocardiogram changes and a high risk for sudden cardiac death (Priori et al., 2013). In addition to the well known electrical substrate, morphological and functional alterations appeared to be present in ...

P.49 Aortic Root Longitudinal Strain by Speckle-Tracking Echocardiography: Comparison with Cardiac Magnetic Resonance and Predictive Value in Marfan Syndrome Patients

Artery Research, 2020
Background: Low longitudinal strain of the ascending aorta (AAo) by cardiac magnetic resonance (CMR) predicts dilation and aortic events in Marfan syndrome (MFS) [1], possibly reflecting aortic stiffness [2].

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

Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

Experimental Physiology, EarlyView.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.
