Objective: to probe into the relationship between blood pressure variability and early stage heart damage of hypertension patients and nursing care of them. Method: a total of 40 cases of hypertension and 21 cases of normal individuals were selected and as test and control groups. 24-hours automatic blood pressure monitoring (ABPM) of them had been performed. Standard difference of blood pressure in different time period was taken as their blood pressure variability index. Meanwhile, both left ventricle myocardial-weight index (LVMI) and plasma type Ⅲ precollagen (PC Ⅲ) concentration of patients had been determined. Results: long term blood pressure variability of each time period in hypertension patients extended more remarkably than that in control group (P<0.001). There were statistical significant differences compared both LVMI and PC Ⅲ concentration of test group patients with that of control group (P<0.05). Moreover, both LVMI and PC Ⅲ concentration of test group patients were significantly correlated with their blood pressure variability in each time period (P<0.05). Conclusion: long term blood pressure variability of hypertension patients possibly related with their left ventricle thickening. Therefore, both to control blood pressure effectively and to reduce the blood pressure variability in hypertension patients could abate their left ventricle thickening.
