The Clinical Valuation Of The Different Ambulatory Blood Pressure Monitoring Parameters In Hypertensive Target Organs Damage

Objective: To explore the clinical values of different ambulatory blood pressure monitoring(ABPM) parameters to hypertensive target organs damage.Methods: 100 primary hypertensive patients were picked out to perform ABPM, and divided into pure hypertension group (hypertension group ) and hypertensive organs damaged group ( organs damaged group )according to the condition with or without target organs damage. The ABPM parameters between the two groups and among the organs damaged group were valuated with statistic methods.Results: (1)nighttime average systolic blood pressure, nighttime average pulse pressure, daytime and nighttime systolic blood pressure load in target organs damaged group were higher than those in hypertension group(p<0.05). (2)The ratio of abnormal day-night rhythm ,24h average systolic blood pressure, nighttime average systolic blood pressure, daytime and nighttime systolic blood pressure load were higher in the patients with 3 target organs damage than those in ones with 1 target organ damage(p<0.05). 24h average diastolic blood pressure, daytime and nighttime average diastolic blood pressure, nighttime systolic and diastolic blood pressure load were higher in the patients with 3 target organs damage than those in ones with 2 target organs damage(p<0.05).24h and daytime average diastolic blood pressure were lower in the patients with 2 target organs damage than those in ones with 1 target organ damage(p<0.05),but 24 h average pulse pressure was higher in the patients with 2 target organs damage than those in ones with 1 target organ damage(p<0.05).Conclusions: ABPM parameters about systolic blood pressure are the most valuable ones in clinical judging hypertensive target organs damage and their extent.
