Abstract: AIM: To explore the correlation between pulse wave velocity (PWV) and indexes of ambulatory blood pressure (ABPM) in patients with hypertension. METHODS: A total of 200 patients with hypertension were divided into two groups: nonelderly (<60 years) group and elderly (≥60 years) group. In both groups, patients were subdivided into two groups: PWV<9 m/sec group and PWV≥9 m/sec group. Clinical data, PWV and indexes of ABPM were collected and the correlation between the indexes of ABPM, other relevant factors and PWV was analyzed. RESULTS: Compared with those in the nonelderly group, waist/hip ratio, pulse pressure (PP), pulse pressure index (PPI) and PWV in the elderly group were significantly higher (P<0.05 or P<0.01). Systolic blood pressure (SBP), diastolic blood pressure (DBP), PP and PPI of patients in PWV≥9 m/sec group were significantly higher than those in PWV <9 m/sec group in the same group (P<0.05 or P<0.01). Pearson correlation analysis showed that PPI was more closely correlated with PWV than with body mass index (BMI), PPI, PP, SBP and DBP. CONCLUSION: PWV is correlated with PP, SBP and DBP and significantly correlated with PPI in patients with hypertension.
