The relationship between arterial wall stiffness and left ventricular dysfunction

Abstract

Objectives The purpose of this study was to explore the relationship between left ventricular (LV) dysfunction and arterial wall stiffening. Methods A total of 218 patients over the age of 45 diagnosed with hypertension in Jinan City and hospitalised between 2010 and 2011 were included in this study. LV function was evaluated using echocardiography (ECHO). Blood pressure was monitored with an automated tonometric device, and the parameters of arterial wall stiffness were measured. In addition, the metabolic parameters of blood samples, such as glucose and lipids, were also determined using the Cobas E601 analyser. Results Stiffness parameter beta positively correlated with LV diastolic function (E/Em ratio) (r00.255, p<0.001). LV enddiastolic diameter not only related to the E/Em ratio (r00.196, p00.009)but also with beta (r00.220, p00.002). The stiffness parameter beta was an early indicator of E/Em ratio as determined by multiple regression analysis (R2 00.381, p<0.01). Age, blood pressure and fasting blood glucose contributed to stiffness parameter beta (p<0.05), as well as the E/Em ratio (p<0.01). Conclusions Our findings suggested that LV dysfunction may have a direct relationship to arterial stiffening, independently of having similar risk factors. In addition, arterial stiffness can be an independent predictor of LV diastolic function, suggesting that the severity of arterial stiffness directly correlates with the severity of LV dysfunction. © Springer Media / Bohn Stafleu van Loghum 2012.
