Trandolapril Attenuates Pro-Arrhythmic Downregulation of Cx43 and Cx40 in Atria of Volume Overloaded Hypertensive and Normotensive Rats [PDF]

Biomolecules
Pressure overload in non-treated or resistant hypertension (HTN) increases the risk of heart failure (HF) as well as the occurrence of fatal ventricular arrhythmias and stroke-provoking atrial fibrillation (AF), while perturbed connexin-43 (Cx43) and ...

Developmental expression of a functional TASK-1 2P domain K⁺ channel in embryonic chick heart [PDF]

Journal of Biomedical Science, 2009
Background Background K+ channels are the principal determinants of the resting membrane potential (RMP) in cardiac myocytes and thus, influence the magnitude and time course of the action potential (AP). Methods RT-PCR and in situ hybridization are used

Transgenic mice overexpressing Pitx2 in the atria develop tachycardia-bradycardia syndrome. [PDF]

PLoS ONE
Sinoatrial node (SAN) dysfunction often accompanies supraventricular tachyarrhythmias such as atrial fibrillation (AF), which is referred to as tachycardia-bradycardia syndrome (TBS). Although there have been many studies on electrical remodeling in TBS,

Small Conductance Ca2 +-Activated K+ (SK) Channel mRNA Expression in Human Atrial and Ventricular Tissue: Comparison Between Donor, Atrial Fibrillation and Heart Failure Tissue

Frontiers in Physiology, 2021
In search of more efficacious and safe pharmacological treatments for atrial fibrillation (AF), atria-selective antiarrhythmic agents have been promoted that target ion channels principally expressed in the atria.

Diabetes Alters the Expression and Translocation of the Insulin-Sensitive Glucose Transporters 4 and 8 in the Atria. [PDF]

PLoS ONE, 2015
Although diabetes has been identified as a major risk factor for atrial fibrillation, little is known about glucose metabolism in the healthy and diabetic atria. Glucose transport into the cell, the rate-limiting step of glucose utilization, is regulated

A Primary Neuroendocrine Tumor Mimicking a Thrombus in the Left Atrial Appendage

대한영상의학회지, 2022
Most cardiac tumors are metastases, and primary cardiac tumors are rare; even among primary cardiac tumors, primary cardiac neuroendocrine tumors (NETs) are extremely rare.

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

Haseki 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]

Einstein (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.
