Cardiovascular disease is the most common cause of mortality in hemodialysis patients. Hypertension is an independent predictor of cardiovascular risk in end-stage renal disease. Noninvasive brachial cuff BP measurement is the principal method for hypertension diagnosis. However, many studies indicate a possible inaccuracy of cuff BP measurement, and whether auscultatory or oscillatory cuff blood pressure accurately measures central blood pressure has never been systematically determined. Many investigators suggest that central blood pressure is more clinically relevant than brachial blood pressure. High central blood pressure causes vascular wall stress in peripheral vasculature such as cerebral and coronary arteries and accelerate atherosclerosis. Recent studies showed that central blood pressure was higher in dialysis group than in the control or early CKD group. In this study we aimed to investigate the clinical value of central blood pressure as a predictor of arterial stiffness in hemodialysis patients.
We reviewed the participants’ medical records, including height, body weight, medication history, etiology of ESRD and HD vintage, and central blood pressure and brachial blood pressure were measured before hemodialysis. Central blood pressure was measured using applanated arterial tonometry (HEM-9000AI, Omron, Japan) For PWV measurement, Patients lie down, rest for at least 5 minutes, and prohibit smoking and coffee for 3 hours before the measurement. BaPWV is measured by recording pulse waves of both arm and both ankles from the pressure signal obtained by measuring 4-extremitiy blood pressure.
The participants were divided into two groups based on median value of pulse pressure (low pulse pressure vs. high pulse pressure ). The participants with high pulse pressure were significantly older compared to those with low pulse pressure (median [IQR]: 72.00 [63.00, 78.25] years vs. 60.00 [53.75, 68.25] years; P<0.001). And the participants with high pulse pressure showed higher prevalence of diabetes. (32(67%) vs. 28(30%), P=0.008). The participants with high pulse pressure had significantly higher brachial and central systolic blood pressure compared to those with low pulse pressure. (median [IQR]: bSBP; 154.00[141.00,158.00] vs. 127.50[118.50,138.25] mmHg; P<0.001, cSBP; 162.00[141.25,17700] vs. 133.00[119.50,143.00] mmHg; P<0.001). After adjusting for age and sex, this study found that there was a significant independent association between central systolic blood pressure and elevated PWV, with a hazard ratio of 1.039 (95% CI 1.015-1.063, P = 0.001)
This study found a strong correlation between central blood pressure and pulse pressure in hemodialysis patients, and an increase in pulse pressure was associated with arterial stiffness. Central blood pressure was found to be significantly and independently associated with arterial stiffness
