Disease studied: Cardiac arrhythmias
Sudden cardiac death as a result of malignant cardiac arrhythmias accounts for 15-20% of all-cause mortality. Currently, the management of patients with cardiac arrhythmias often is based on the implantation of electronic devices (pacemakers or defibrillators) to prevent fatal outcome, while causative therapies are not yet established. The voltage-gated sodium channel Nav1.5 underlies the depolarizing current INa, which is a key component for generation and propagation of the cardiac action potential. Loss of Nav1.5 function is associated with high arrhythmogenic risk in primary Mendelian rhythm disorders, as well as prevalent in heart failure and in acquired pathologies such as myocardial ischemia. Patrick aims to elucidate the mechanisms of sodium channel associated arrhythmias in vivo and at the molecular level using genetically altered mice and human samples. To do so he will study the molecular pathways that underlie maladaptive trafficking of Nav1.5 to the cell membrane leading to arrhythmias. It is the ultimate goal of this project to explore specific targets for the development of new antiarrhythmic strategies.
