Evaluation of the ATRIA and CHA2DS2-VASc Scores and Their Performance on Predicting Mortality in Patients with Acute Pulmonary Embolism

open access: yesHaseki Tıp Bülteni, 2022
Aim:Pulmonary embolism (PE) is a condition caused by thrombosis and is a common cause of death. Although there are studies of PE with CHA2DS2-VASc (C: congestive heart failure or left ventricular systolic dysfunction, H: hypertension, A: age of ≥75 years,

Fast growth rate of a right atrial myxoma [PDF]

open access: yesEinstein (São Paulo), 2022
Primary cardiac tumors are rare, with an incidence between 0.0017 and 0.19%, and are asymptomatic in up to 72% of cases. Approximately 75% of tumors are benign, and nearly 50% of these are myxomas.

Multi-chamber cardioids unravel human heart development and cardiac defects

open access: yesCell, 2022
The number one cause of human fetal death are defects in heart development. Because the human embryonic heart is inaccessible, and the impacts of mutations, drugs, and environmental factors on the specialized functions of different heart compartments are

The Role of Lyophilized Xenodermotransplants in Repairing the Atria’s Structure and the Peculiarities of Regenerative Processes after Thermal Trauma in an Experiment

open access: yesLife, 2023
The effects of severe burn injuries on the cardiovascular system, specifically the atria and auricles of the heart, were investigated. The potential benefits of using lyophilized xenodermotransplants as a treatment option were also evaluated.

Unusual massive fatty infiltration of the heart in a British cat: a case report

open access: yesVeterinární Medicína, 2011
A British cat was presented with generalized fatty infiltration of the heart compromising both ventricles and atria, resembling arrhythmogenic right ventricular cardiomyopathy.

Topographical mapping of catecholaminergic axon innervation in the flat-mounts of the mouse atria: a quantitative analysis

open access: yesScientific Reports, 2023
The sympathetic nervous system is crucial for controlling multiple cardiac functions. However, a comprehensive, detailed neuroanatomical map of the sympathetic innervation of the heart is unavailable.

Profibrotic, Electrical, and Calcium-Handling Remodeling of the Atria in Heart Failure Patients With and Without Atrial Fibrillation

open access: yesFrontiers in Physiology, 2018
Atrial fibrillation (AF) and heart failure (HF) are common cardiovascular diseases that often co-exist. Animal models have suggested complex AF-promoting atrial structural, electrical, and Ca2+-handling remodeling in the setting of HF, but data in human ...

Electro-Mechanical Whole-Heart Digital Twins: A Fully Coupled Multi-Physics Approach

open access: yesMathematics, 2021
Mathematical models of the human heart are evolving to become a cornerstone of precision medicine and support clinical decision making by providing a powerful tool to understand the mechanisms underlying pathophysiological conditions.

A comprehensive and biophysically detailed computational model of the whole human heart electromechanics [PDF]

open access: yes, 2022
While ventricular electromechanics is extensively studied, four-chamber heart models have only been addressed recently; most of these works however neglect atrial contraction. Indeed, as atria are characterized by a complex physiology influenced by the ventricular function, developing computational models able to capture the physiological atrial ...
