INCREASED MYOCARDIAL STIFFNESS ESTIMATED BY INTRINSIC VELOCITY PROPAGATION METHOD IS ASSOCIATED WITH ADVERSE CARDIAC EVENTS AT FOLLOW-UP IN PATIENTS WITH AMYLOIDOSIS

Cardiac deposition of amyloid fibrils increases myocardial stiffness. Intrinsic velocity propagation (iVP) of myocardial stretch is a new validated measure of myocardial elasticity. Herein, we tested whether quantitative measurement of myocardial elasticity (stiffness) by iVP is related to outcomes
