Abstract

Abstract:

Objective To investigate the relationship between left atrial diameter (LAD) and the red blood cell distribution width (RDW) in patients with primary hypertension. Methods Overall 580 patients with essential hypertension were enrolled into our study. All patients were divided into LAD enlarged group (LAD≥40 mm, 196 cases) and non-LAD enlarged group (LAD< 40 mm, 384 cases). Results The age, pulse pressure, body mass index and left ventricular mass index in LAD enlarged group were significantly higher, but the level of left ventricular ejection fraction and cardiac output were lower than those in non-LAD enlarged group. The difference was statistically significant (P <0.05). Multiple linear regression analysis results showed that age, pulse pressure, body mass index, left ventricular mass index and RDW had a linear positive correlation with LAD. Multivariate logistic regression analysis showed that RDW was an independent predictor for the patients primary hypertension with LAD enlargement (OR=1.269,95%CI:1.018-1.582,P=0.034). Conclusion In primary hypertension patients, LAD is correlated with the level of RDW. RDW is an independent predictor for primary hypertension with LAD enlargement.
