BACKGROUND: Accumulating evidence suggests that increased red cell distribution width (RDW) and mean corpuscular volume (MCV) were both poor prognostic factors for patients with cardiovascular diseases. Recently, the multiplicative interaction between RDW and MCV has been observed for predicting mortality in elderly patients without anemia; however, the relationship between the product of RDW-MCV and hypertension-induced target organ damage (TOD) has not been evaluated.

METHODS: We performed a cross-sectional study in 1115 hypertensive patients. RDW and MCV were determined using automated hematology analyzers. Prevalence of TOD was evaluated by estimated glomerular filtration rate, carotid intima-media thickness, and left ventricular mass index.

RESULTS: The prevalence of TOD was observed to be increased with the RDW or product of RDW-MCV quartiles. Moreover, RDW, MCV and product of RDW-MCV were significantly higher in patients with TOD compared to those without TOD. According to two logistic regression models, the associations of RDW and MCV with TOD were lost after adjustment for other factors. However, product of RDW-MCV remains an independent predictor of TOD, with per 0.4 fL increase in the product of RDW-MCV associated with a 16% increased risk of TOD (P=.012).

CONCLUSIONS: The inclusion of MCV by calculating the product of RDW-MCV appears to enhance the association of RDW with TOD.
