  • Clinical significance of blood pressure variability in chronic kidney disease and hemodialytic patients

    Blood pressure variability (BPV) is a novel predictor related to blood pressure level, and a large number of studies based on the hypertension cohort have shown that BPV is an independent predictor of target organ damages and cardiovascular adverse outcomes. Due to the significant hemodynamic changes, BPV in patients with chronic kidney disease (CKD) and hemodialysis is higher than the simple hypertension cohort, suggesting that BPV may be of great significance to patients with chronic kidney disease and hemodialysis. In recent years, studies based on CKD and hemodialysis cohort have published in succession whose results revealed that BPV of this cohort is of great prognostic significance for predicting target organ damages and cardiovascular disease risks. This article aims to provide an overview on these research, so as to survey and predict the clinical significance of BPV in CKD and hemodialytic patients.

  • Arteriosclerosis in patients with hypertension defined by AHA and classical diagnostic criteria: a cross-sectional study

    ObjectiveTo evaluate the level of arteriosclerosis in patients with hypertension defined by the American Heart Association (AHA) and classical diagnostic criteria. MethodsA total of 3 815 residents were enrolled in 10 communities in north Shanghai. According to the classic diagnostic criteria of hypertension (systolic blood pressure≥140 mmHg and/or diastolic blood pressure≥90 mmHg) and AHA diagnostic criteria (systolic blood pressure≥130 mmHg and/or diastolic blood pressure≥80 mmHg), the population was divided into normal blood pressure group, AHA diagnosis standard hypertension group, and classic methods of diagnosis of hypertension group. The differences in cervical-femoral pulse wave velocity (cf-PWV) and brachial-ankle pulse wave velocity (ba-PWV) among the three groups were compared. SPSS 13.0 software was then used for data analysis.ResultsCompared with the patients who met the standard criteria, patients who met AHA criteria had lower mean ages (70.2±7.4 vs. 71.4±7.9 year, P<0.001), more history of hypertension (48.8% vs. 72.7%, P<0.001) and lower body mass index (24.1±3.5 vs. 24.7±3.9 kg/m2, P<0.001), low-density lipoprotein (3.07±0.92 vs. 3.15±0.97 mmol/L, P=0.033), cf-PWV (8.7±2.7 vs. 9.8±3.0 m/s, P<0.001) and ba-PWV (1 647.7±610.1 vs. 1 797.2±729.7 cm/s, P<0.001). ConclusionsThe degree of arteriosclerosis of patients who meet AHA standards is between that who meet the standard criteria and the normal population. For these patients, blood pressure should be actively controlled to delay the progression of arteriosclerosis.
