Compliant Titin Isoform Content Is Reduced in Left Ventricles of Sedentary Versus Active Rats

open access: yesFrontiers in Physiology, 2020
A sedentary lifestyle is associated with increased cardiovascular risk factors and reduced cardiac compliance when compared to a lifestyle that includes exercise training.

Need for Speed: The Importance of Physiological Strain Rates in Determining Myocardial Stiffness

open access: yesFrontiers in Physiology, 2021
The heart is viscoelastic, meaning its compliance is inversely proportional to the speed at which it stretches. During diastolic filling, the left ventricle rapidly expands at rates where viscoelastic forces impact ventricular compliance.

The significant coronary tortuosity and atherosclerotic coronary artery disease; What is the relation? [PDF]

open access: yesJournal of Cardiovascular and Thoracic Research, 2018
Introduction: Although coronary tortuosity is relatively common in coronary angiograms, there is much debate over the significance of this anatomical variation.

Inorganic phosphate accelerates cardiac myofilament relaxation in response to lengthening

open access: yesFrontiers in Physiology, 2022
Myocardial relaxation in late systole is enhanced by increasing velocities of lengthening. Given that inorganic phosphate (Pi) can rebind to the force-producing myosin enzyme prior to MgADP release and hasten crossbridge detachment, we hypothesized that ...

Differences between the Filling Velocities of the Left and Right Heart Ventricle in Racing Pigeons (Columba livia F. Domestica) and the Influence of Anesthesia with Isoflurane

open access: yesVeterinary Sciences, 2019
The ventricular filling velocities during diastole and the influence of isoflurane anesthesia on these blood flow velocities of the racing pigeon (n = 43) are evaluated by pulsed-wave (PW) Doppler sonography. Sonographic examination demonstrates an early

Color Flow Doppler Echocardiography in Healthy Racing Pigeons (Columba livia f. domestica) and the Evidence of Physiological Blood Flow Vortex Formations

open access: yesVeterinary Sciences, 2020
In avian medicine, Doppler sonographic techniques are used to visualize and estimate blood flow in the heart. In the literature there is a lack of standardized studies of the use of color Doppler flow on healthy avian species.
