statistically lower number of abnormal aortic stiffness index than the
ischemia group (p<0.001)
Conclusion: Aortic stiffness index and distensibility, parameters
measuring aortic elasticity, may improve diagnostic accuracy of singlephoton emission computed tomography MPS, especially in suspected
cases with the equivocal results.

Background: In hypertrophic cardiomyopathy (HCM) cardiac ﬁbrosis
is an important contributor of adverse left ventricular (LV) remodelling
and arrhythmias. Galectin-3 (Gal-3) is a novel marker of cardiac ﬁbrosis
and inﬂamation. In this study we investigated the levels of Gal-3 in
patients with HCM and control subjects and assessed the relationship
between Gal-3 levels and echocardiographic indices using strain
echocardiography.
Methods: Forty patients with HCM and 35 healthy control subjects
were enrolled. Global LV strain and strain rates, LV mass index (LVMI)
of all subjects were assessed by echocardiography. Galectin-3 levels of
all subjects were measured.
Results: Global LV longitudinal strain (13.374.6% vs.
18.932.5%, p<0.001) and strain rate (0.660.22 vs. 1.080.14,
respectively; p<0.001) values were lower in patients with HCM than in
those of controls. Levels of Gal-3 were signiﬁcantly higher in patients
with HCM than in controls (16.36.74 ng/mL vs. 13.213.42 ng/mL,
p¼0.017). The Gal-3 levels were associated with thickness of interventricular septum (r¼0.444, p¼ 0.004) and LVMI (r¼ 0.365,
p¼0.021) (Fig.1) however were not associated with global LV longitudinal strain (p¼0.42) and strain rate (p¼0.28).
Conclusion: Galectin-3 levels are increased and related with the
degree of LV hypertrophy in patients with HCM. In patients with
HCM, Gal-3 seems to be not a good marker of decreased myocardial
functions.
