Suppression of premature ventricular complexes with the PDE5 inhibitor sildenafil: First clinical experience

Experimental Physiology, EarlyView.
Abstract The phosphodiesterase‐5 inhibitor sildenafil suppresses ventricular arrhythmias in a sheep model of drug‐induced long QT. In that study, ventricular arrhythmias were abolished by reducing premature ventricular complexes (PVCs) and delaying PVC onset, thus preventing ‘R‐on‐T’ ventricular tachycardia.

Alveolar deadspace and intrapulmonary shunt in healthy individuals and in individuals who have recovered from COVID‐19 infection

Experimental Physiology, EarlyView.
Abstract Following acute COVID‐19 infection, unvaccinated patients have been reported to exhibit elevated alveolar deadspace (̇VD,alv/̇VT) and intrapulmonary shunt (̇Qs/̇QT) fractions. However, as there is uncertainty surrounding the upper limits of normal for ̇VD,alv/̇VT and ̇Qs/̇QT, we sought to replicate the findings from a separate, previously ...

Cardiac‐specific Kv1.1 deficiency alters cardiomyocyte electrophysiology without modifying overall cardiac function or arrhythmia susceptibility

Experimental Physiology, EarlyView.
Abstract The leading cause of epilepsy‐related mortality is sudden unexpected death in epilepsy (SUDEP), resulting from seizure‐induced cardiorespiratory arrest by mechanisms that remain unresolved. Mutations in ion channel genes expressed in both brain and heart represent SUDEP risk factors because they can disrupt neural and cardiac rhythms ...

The causative role of amyloidosis in the cardiac complications of Alzheimer's disease: a comprehensive systematic review

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic illustration of the bidirectional causative link between cerebral amyloid‐beta (Aβ) angiopathy and cardiovascular disease in Alzheimer's disease (AD). Common cardiovascular risk factors like microvascular thrombosis, diabetes, atrial fibrillation, hypertension and atherosclerosis lead to cerebral hypoperfusion and ...
