PO-05-201 PHARMACOLOGICAL MODULATION OF THE ARRHYTHMIC SUBSTRATE IN TIMOTHY SYNDROME: A PORCINE MODEL STUDY

HeartRhythm

Contemporary antiarrhythmic treatment of Timothy syndrome 1 (TS1) is inadequate to prevent sudden cardiac death. Using electroanatomic mapping (EAM) we discovered cardiac activation delay, which creates the milieu for functional reentrant ventricular arrhythmias.

Lowering Atherosclerotic Cardiovascular Disease Events by Treating Residual Inflammatory Risk

DAIC

21-23 hsCRP is nonspecific inflammatory marker and an acute phase reactant that predicts the likelihood of a heart attack, stroke, peripheral artery disease and sudden cardiac death among healthy individuals with no history of CV disease, and recurrent events and death in patients with known ASCVD.22 2015;45(3):341-350.
