Generally, as compared to patients without RH, patients with RH were more elderly (59.3 ± 10.1 years versus 53.2 ± 11.4 years, P = 0.018), had higher percentages of male (76.2 % versus 62.7 %, P < 0.001) and smokers (64.3 % versus 60.2 %, P = 0.037), longer duration of hypertension (6.5 ± 3.7 years versus 4.0 ± 2.1 years, P = 0.022), higher CRP level (24.7 ± 5.0 mg/L versus 15.2 ± 5.4 mg/L, P < 0.001) and Lp-PLA2 activity (254.2 ± 26.7 nmol/min/mL versus 228.1 ± 24.5 nmol/min/mL, P < 0.001). This evidence concerns the gene PLA2G7 and Hypertension.
