Those with grade 2 or grade 3 hypertension were older (P<0.05) and had higher CAP value (P<0.05), while those with grade 3 hypertension had higher CMV IgG, IL-6 and FBS values (P<0.05) than those with grade 1 or grade 2 hypertension; had higher TG and LVIDd values (P<0.05) and higher incidence of brain infarction than those with grade 1 hypertension; and had higher weight, BMI, and IVSd value than (P<0.05) those with grade 2 hypertension.
