Abstract:
【Objective】To assess the difference in volume load between different blood pressure control levels in outpatients with hypertension. To investigate the effect of clinical factors on volume load in outpatients with hypertension. To analyze the clinical baseline characteristics and use of antihypertensive drugs in outpatients with hypertension. 【Methods】 A total of 514 outpatients with hypertension were included from July to November 2017. Clinical indicators including gender,age,height,weight,years of hypertension,blood pressure levels,treatment options for hypertension and comorbidities of these patients were recorded. The body volume load was evaluated by detecting the ratio of extracellular fluid(ECW)to total body water(TBW)using a Bioimpedance Analyzer. Whole body ECW/TBW≥0.39 was defined as high volume load. The effects of clinical factors on the volume load of hypertensive patients and whether there was a difference in volume load between different antihypertensive therapy were analyzed. 【Results】The blood pressure compliance rate of outpatients with hypertension was 15.37% ,which was still very low. Male patients had lower blood pressure compliance rate than female patients. Blood pressure was more difficult to control in patients with older age ,higher body mass index (BMI),higher waist-to-hip ratio(WHR)or longer duration of hypertension. The higher the blood pressure grading,the higher the proportion of combination medication. Diuretics were still the most widely used antihypertensive drugs. Age ,gender and different hypertension grades were the main factors affecting the volume load of hypertensive patients. Volume load was higher in female,older or higher systolic blood pressure(SBP)patients. Among them,age was the most important factor affecting the volume load of hypertensive patients.【Conclusion】The blood pressure compliance rate of outpatients with hypertension was still low. Effectively reducing the volume load was one of the important means to control blood pressure,which was more important in female,older or higher SBP patients.
