Key result
Hypertensive patients with absent or mild-to-moderate left ventricular hypertrophy had a significantly lower cyclic variation index in the septum (P<0.001) and posterior wall (P<0.0001) than controls.
Why the study?
Does myocardial texture analysis (CVI) differ between hypertensive patients with absent-to-moderate left ventricular hypertrophy and normotensive controls?

Suggests early myocardial changes in hypertension independent of LVH; hypothesis-generating for CVI as a sensitive marker.

Does myocardial texture analysis (CVI) differ between hypertensive patients with absent-to-moderate left ventricular hypertrophy and normotensive controls?
p-value: p=<.001
Abnormalities in two-dimensional echocardiographic gray level distribution (lower CVI) are present in hypertensive patients even without severe LVH, and correlate with systolic blood pressure rather than the degree of hypertrophy.
V. Di Bello (1998) conducted a case-control in Essential hypertension with absent or mild-to-moderate left ventricular hypertrophy (n=36). Essential hypertension vs. Normotensive sedentary healthy subjects was evaluated on Cyclic variation index (CVI) of the septum and posterior wall (p=<.001). Hypertensive patients with absent or mild-to-moderate left ventricular hypertrophy had a significantly lower cyclic variation index in the septum (P<0.001) and posterior wall (P<0.0001) than controls.
