老年体位性低血压与心血管疾病风险及住院率的关系

The Relationship between Elderly Orthostatic Hypotension and Risk of Cardiovascular Disease and the Hospitalization Rate

目的：探讨老年体位性低血压（orthostatic hypotention,OH）与心血管疾病风险及住院率的关系。方法：选择2012年1月至2014年1月在我院进行体检的208例老年人进行研究。208例研究对象中,有68例OH者（OH组）及140例非OH者（非OH组）。对比2组的主要临床资料,不同年龄段的血糖异常及血脂异常者的患病率,采用Logistic回归法评价老年OH和心血管疾病的风险以及住院率的关系。结果：OH组的坐位心率显著低于非OH组,年龄、卧位收缩压、卧位舒张压、心绞痛、心肌梗死及住院率均显著高于非OH组,差异均有统计学意义（P〈0.05或0.01）。不同年龄段的血糖异常及血脂异常者的患病率差异均无统计学意义（P〉0.05）。Logistic回归结果显示心绞痛（OR=2.134,95%CI：1.027～3.801）及心肌梗死（OR=8.963,95%CI：2.084～27.368）是老年OH的独立危险因素。结论：老年OH与其心血管疾病风险以及住院率的关系十分紧密,临床上应重点对此种现象加以监测,从而更好地防治老年OH。

Objective： To study the relationship between the elderly orthostatic hypotension（ OH） and risk of cardiovascular disease and the hospitalization rate. Methods： From Jan 2012 to Jan 2014,208 cases of the elder for health examination in our hospital were enrolled. There were 68 cases with OH（ OH group） and 140 cases without OH（ non-OH group）. The main clinical data,the prevalence of abnormal blood glucose and blood lipid in different age were compared in two groups. The evaluation method for the analysis and Logistic regression was used to evaluate the relationship between OH and the risk of cardiovascular disease and hospitalization rates. Results： The heart rate in the seat in OH group was significantly lower than in the non-OH groups. Age,SBP and DBP in lie position,angina pectoris,myocardial infarction,and hospitalization rates were significantly higher than that those in the non-OH groups（ P〈0. 05 or 0. 01）. There was no statistical significance in the abnormal blood sugar and blood fat in different age（ P〉0. 05）. Angina pectoris（ OR = 2. 134,95% CI： 1. 027-3. 801） and myocardial infarction（ OR = 8. 963,95% CI： 2. 084-27. 368） was the independent risk factors of elderly OH. Conclusions： The relationship between elderly OH and cardiovascular disease risk and hospitalization rate is very close,and we should focus on clinical monitoring,to prevent and treat elderly OH.
