Influence of reversed dipper blood pressure pattern on target organ damage in patients with chronic kidney disease / 中华肾脏病杂志

ABSTRACT

Objective To explore the relationship between reversed dipper blood pressure (BP) pattern with target organ damage in Chinese chronic kidney disease (CKD) patients. Methods A total of 1 116 CKD patients from the Third hospital of Sun Yat?sen university were enrolled from May 2010 to April 2014, all of whom carried ambulatory blood pressure monitoring (ABPM), and clinical data and ultrasonography were collected. Results Total of 23.39% CKD patients were reversed dipper BP pattern, 46.95% patients were non?dipper BP pattern, and dipper BP pattern was only 27.15%. Compared with dipper and non?dipper BP pattern group, patients with reversed dipper BP pattern had higher left ventricular mass index (LVMI), lower estimated glomerular filtration rate (eGFR) and severely damaged left ventricular diastolic function (all P<0.0083). After multiple linear regression analysis, reversed dipper BP pattern was an independent predictor for determining eGFR and LVMI. Age, lower hemoglobin and combination of diabetes were independently associated with reversed dipper BP pattern. Conclusion Reversed dipper BP pattern is common in Chinese CKD patients, which is closely related to renal damage and cardiovascular injuries.
