Mast Cell Stabilization Decreases Cardiomyocyte And Lv Function In Dogs With Isolated Mitral Regurgitation., Betty Pat, Cheryl Killingsworth, Yuanwen Chen, James D Gladden, Greg Walcott, Pamela C Powell, Thomas Denney, Himanshu Gupta, Ravi Desai, Michael Tillson, A Ray Dillon, Louis J Dell'italia

Ravi V Desai MD

BACKGROUND: Mast cells are increased in isolated mitral regurgitation (MR) in the dog and may mediate extracellular matrix loss and left ventricular (LV) dilatation. We tested the hypothesis that mast cell stabilization would attenuate LV remodeling and improve function in the MR dog.

METHODS AND RESULTS: MR was induced in adult dogs randomized to no treatment (MR, n = 5) or to the mast cell stabilizer, ketotifen (MR + MCS, n = 4) for 4 months. LV hemodynamics were obtained at baseline and after 4 months of MR and magnetic resonance imaging (MRI) was performed at sacrifice. MRI-derived, serial, short-axis …

Chymase Inhibition Prevents Fibronectin And Myofibrillar Loss And Improves Cardiomyocyte Function And Lv Torsion Angle In Dogs With Isolated Mitral Regurgitation., Betty Pat, Yuanwen Chen, Cheryl Killingsworth, James D Gladden, Ke Shi, Junying Zheng, Pamela C Powell, Greg Walcott, Mustafa I Ahmed, Himanshu Gupta, Ravi Desai, Chih-Chang Wei, Naoki Hase, Tsunefumi Kobayashi, Abdelkarim Sabri, Henk Granzier, Thomas Denney, Michael Tillson, A Ray Dillon, Ahsan Husain, Louis J Dell'italia

BACKGROUND: The left ventricular (LV) dilatation of isolated mitral regurgitation (MR) is associated with an increase in chymase and a decrease in interstitial collagen and extracellular matrix. In addition to profibrotic effects, chymase has significant antifibrotic actions because it activates matrix metalloproteinases and kallikrein and degrades fibronectin. Thus, we hypothesize that chymase inhibitor (CI) will attenuate extracellular matrix loss and LV remodeling in MR.

METHODS AND RESULTS: We studied dogs with 4 months of untreated MR (MR; n=9) or MR treated with CI (MR+CI; n=8). Cine MRI demonstrated a >40% increase in LV end-diastolic volume in both groups, consistent with …
