浅析老年人餐后高血糖与冠心病的关系

目的分析老年人单纯餐后高血糖（IPH）的患病情况，并了解其与冠心病的关系。方法对院参加健康体检的1020例进行问卷调查，测量空腹血糖（FPG）及餐后2h血糖（PPG2h），并进行冠心病的检诊。结果确诊IPH患病率为12．45％，糖耐量异常（IGT）患病率16．67％，女性患病率稍高于男性；确诊IPH和IGT的患病率老年组较非老年组明显增高，且女性患病率的增高更剧。随年龄增长，冠心病的危险性也增加。多因素分析显示，冠心病与年龄增长和餐后血糖的升高呈正相关（分别为P〈0.05和P〈0．01）。结论老年人餐后血糖（PPG2h）升高是危害老年人健康的主要心血管危险因素，并是预测冠心病的重要指标，需加强宣传和防治。

The analysis of postprandial hyperglycemia and coronary heart disease in the elderly.

Objective To investigate the prevalence of isolated postprandial hyperglycemia （IPH） and risk of coronary heart disease in the elderly. Methods This study was collected on the annual health screening for government employees and involved 1 020 subjects. And the surveyed items included measurement of fasting plasma glucose （FPG） and postchallenge plasma glucose two hours （ PPG2 h）, and some risk factors of diabetes mellitus and coronary heart disease. All the interviewers were trained before participating in the survey. Resuits The prevalence of IPH was 12.45%, and that of impaired glucose tolerance （IGT） was 16.67%, being little higher in women than those in men ; the prevalence of IPH and IGT rose with increase of age. The increase was remarkable in women. The risk of coronary heart disease also rose with increase of age. Multivariate analysis showed coronary heart disease was positively related with age （P 〈 0. 05 ） and increase of postchallenge plasma glucose （P 〈0.01 ）. Conclusion IPH is much common in the elderly. It seriously endangers the health of aged people and is associated with higher relative risk of coronary heart disease. Prevention of diabetes mellitus in community population should be further strengthened.
