Genetic Deletion of ASIC3 Alters Left Ventricular Remodeling and Autonomic Function After Myocardial Infarction in Mice.

ABSTRACT: Chronic overactivation of neurohormonal systems is the principal driver of adverse cardiac remodeling following myocardial infarction (MI). Recent data suggest that ablating cardiac afferent neurons in rats attenuates left ventricular (LV) remodeling following MI by blocking this overactivation. Our lab has shown that acid-sensing ion channels (ASICs) are highly expressed in cardiac afferents and may sense myocardial acidosis. We hypothesized that genetic deletion of ASICs might abrogate disadvantageous remodeling after MI by disrupting afferent signaling pathways otherwise resulting in overactivation of neurohormonal responses. To test this hypothesis, we induced MI by coronary artery ligation in wild type (WT) and ASIC3^-/- mice and assessed cardiac remodeling by serial echocar
