中文摘要：

目的调查老年高血压合并糖尿病前期患者心血管危险因素分布。方法收集年龄≥60岁、既往无糖尿病病史、且入院空腹血糖（FPG）〈7.0mmol/L的高血压患者388例,以空腹血糖受损（IFG）诊断标准为FPG≥5.6mmol/L,分为A组260例（FPG〈5.6mmol/L）、B组65例（5.6mmol/L≤FPG〈6.1mmol/L）及C组63例（6.1mmol/L≤FPG〈7mmol/L）,比较3组各种心血管危险因素分布的差异。结果 338例患者中,IFG患病率33.0%。与A组比较,B组和C组高血压≥2级或高血压高危、左心室舒张功能障碍、颈动脉增厚比例等无明显变化（P〉0.05）。结论尽管未发现IFG与其他心血管危险因素有关,但糖代谢异常在此类患者中的影响应予重视。

英文摘要：

Objective To investigate the distribution of cardiovascular risk factors in elderly hypertensive prediabetes patients.Methods Three hundred and eighty-eight patients aged ≥60years were included in this study.The patients had no history of diabetes and their FPG was 〈7.0 mmol/L at admission.The patients were divided into group A with its FPG〈5.6mmol/L,group B with its FPG≥5.6mmol/L,〈6.1mmol/L and group C with its FPG≥6.1mmol/L,〈7mmol/L. The distribution of cardiovascular risk factors in 3groups was compared.Results The incidence of IFG was 33.0%in the 388patients.No significant difference was found in grade 2hypertension or high risk hypertension,diastolic dysfunction and carotid artery thickness among the 3groups（P〉0.05）.Conclusion Abnormal glucose metabolism and multiple cardiovascular risk factors are requently found in elderly hypertensive prediabetes patients.
