Cardiac amyloidosis and hypertrophic cardiomyopathy can be both characterized with increased wall thickness. We intended to explore the microvascular function of the two different phenotypes of hypertrophy and its relation with regional myocardial function. Amyloid infiltration caused more severe myocardial perfusion disorder and systolic dysfunction. Significant correlations were observed between microcirculation and myocardial strain.
