Key result
Each 10% increase in radial augmentation index was associated with an adjusted relative risk of 1.99 for left ventricular hypertrophy in untreated hypertensive patients (P=0.005).
Why the study?
Does radial late systolic pressure augmentation correlate with the presence of left ventricular hypertrophy in untreated hypertensive patients?
Population
77 untreated hypertensive patients, mean age 56 +/- 10 years.

Radial AI may flag LVH risk in untreated hypertension; leaves open incremental value and causal links pending prospective data.

Does radial late systolic pressure augmentation correlate with the presence of left ventricular hypertrophy in untreated hypertensive patients?
Relative Risk: 1.99
p-value: p=.005
Peripheral radial augmentation index (AI(r)) is independently associated with left ventricular hypertrophy in untreated hypertensive patients, suggesting its potential utility as a non-invasive predictive marker.
Hashimoto et al. (2006) conducted a cross-sectional in Hypertension (n=77). Late systolic pressure augmentation (radial augmentation index) vs. Lower radial augmentation index was evaluated on Left ventricular hypertrophy (LVH) (RR 1.99, p=.005). Each 10% increase in radial augmentation index was associated with an adjusted relative risk of 1.99 for left ventricular hypertrophy in untreated hypertensive patients (P=0.005).
