Key result
Patients with hypertrophic cardiomyopathy had a normal carotid intima-media thickness (0.61 mm) compared to normotensive subjects (0.60 mm), unlike hypertensive subjects with LVH (0.73 mm).
Why the study?
Does carotid artery intima-media thickness differ between patients with hypertrophic cardiomyopathy, hypertensive left ventricular hypertrophy, and normotensive subjects?

May aid noninvasive differentiation of HCM from hypertensive LVH; leaves open prospective validation before clinical use.

Does carotid artery intima-media thickness differ between patients with hypertrophic cardiomyopathy, hypertensive left ventricular hypertrophy, and normotensive subjects?
Absolute Event Rate: 0.61% vs 0.6%
Carotid intima-media thickness is normal in hypertrophic cardiomyopathy but increased in hypertensive left ventricular hypertrophy, providing a useful non-invasive parameter to differentiate the two conditions.
Ohya et al. (1997) conducted a cross-sectional in Hypertrophic cardiomyopathy and hypertension (n=760). Hypertrophic cardiomyopathy vs. Normotension and hypertension was evaluated on Intima-media thickness of carotid arteries. Patients with hypertrophic cardiomyopathy had a normal carotid intima-media thickness (0.61 mm) compared to normotensive subjects (0.60 mm), unlike hypertensive subjects with LVH (0.73 mm).
