Neck‐vein thrombosis during spaceflight

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Spaceflight imposes unique environmental challenges, including weightlessness, increased radiation exposure and confinement, which can lead to unexpected health effects. One such example is neck‐vein thrombosis, a condition rarely seen on Earth without predisposing factors such as venous catheters or infections.

Anesthetic management of a patient with severe aortic regurgitation undergoing reoperation for ascending aorta false aneurysm using hypothermia: prevention of ventricular fibrillation by nifekalant

open access: yesJA Clinical Reports, 2021
Background To prevent cardiac collapse and to protect cerebral function, hypothermic cardiopulmonary bypass is established before resternotomy. However, ventricular fibrillation under hypothermia facilitates left ventricular distension, which causes ...

Nonlinear physics of electrical wave propagation in the heart: a review [PDF]

open access: yes, 2016
The beating of the heart is a synchronized contraction of muscle cells (myocytes) that are triggered by a periodic sequence of electrical waves (action potentials) originating in the sino-atrial node and propagating over the atria and the ventricles ...

Clinical Outcomes Post‐Transcatheter Aortic Valve Replacement in Patients With Hypertrophic Obstructive Cardiomyopathy

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Patients with hypertrophic obstructive cardiomyopathy (HOCM) were excluded from all major trials for transcatheter aortic valve replacement (TAVR). “Suicide left ventricle” occurring after TAVR is postulated to occur as a result of chronic pressure overload from fixed obstruction that is acutely relieved after the valve deployment ...

The Prognostic Value of Troponin in Acute Pulmonary Embolism: A Systematic Review and Meta‐Analysis

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Acute pulmonary embolism (PE) is a major cause of cardiovascular morbidity and mortality. Troponin elevation is increasingly used for risk stratification, but its prognostic utility remains variably reported across studies. To evaluate the prognostic value of troponin elevation in patients with acute PE, concerning short‐term mortality and ...

The role of inhibitory G proteins and regulators of G protein signaling in the in vivo control of heart rate and predisposition to cardiac arrhythmias [PDF]

open access: yes, 2012
Inhibitory heterotrimeric G proteins and the control of heart rate. The activation of cell signaling pathways involving inhibitory heterotrimeric G proteins acts to slow the heart rate via modulation of ion channels.

Left Ventricular Apical Thrombus in Apical Hypertrophic Cardiomyopathy Without Aneurysm or Arrhythmia: A Case Report

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Apical hypertrophic cardiomyopathy (ApHCM) is a rare variant of hypertrophic cardiomyopathy, typically associated with a benign course. However, complications such as ventricular arrhythmias, apical aneurysms, and thrombus formation may occur. Left ventricular (LV) thrombus is an unusual finding in ApHCM, especially in patients with preserved ...
