動(dòng)態(tài)動(dòng)脈硬化指數(shù)與老年高血壓患者心律失常的相關(guān)性研究

摘要：目的 分析動(dòng)態(tài)動(dòng)脈硬化指數(shù)（AASI）以及老年高血壓患者心律失常兩者間存在的關(guān)系。方法 將148例老年高血壓患者根據(jù)（AASI）的差異分為對(duì)照組（低值組）及觀察組（高值組），每組74例，以0.49為中位數(shù)，前者的AASI均不超過(guò)0.49，后者的AASI均大于0.49，針對(duì)兩組患者的動(dòng)態(tài)血壓變化和心律失常狀況等進(jìn)行實(shí)時(shí)觀察并詳細(xì)記錄。結(jié)果 觀察組24h SBP值和24h PP值均明顯比對(duì)照組高（P<0.05）；觀察組24h DBP明顯比對(duì)照組低（P<0.05）；觀察組室性期前收縮率、復(fù)雜性室性心律失常率以及房性期前收縮率等均比對(duì)照組高（P<0.05）。結(jié)論 針對(duì)老年高血壓患者，其動(dòng)態(tài)動(dòng)脈硬化指數(shù)的升高會(huì)增加其心律失常發(fā)生風(fēng)險(xiǎn)。

Abstract：Objective To analyze dynamic arterial stiffness index（AASI）and the relation between the arrhythmia in elderly patients with high blood pressure.Methods 148 cases of elderly patients with high blood pressure，according to the different（AASI）in control group were set up group（undervalued）and observation group（high value），74 cases in each group，with 0.49 for the median，the former of AASI are not more than 0.49，and the latter AASI were greater than 0.49，in view of the two groups of patients with dynamic changes in blood pressure and arrhythmia in the real-time observation and record in detail.Results 24 hSBP value and 24 hPP observation group were significantly higher than control group（P<0.05）；24 hDBP observation group was obviously lower than the control group（P<0.05）；Observation group reduction before sexual period，complexity of ventricular arrhythmia reduction rate and room before are higher than the control group（P<0.05）.Conclusion In elderly patients with high blood pressure，the increase of the dynamic index of atherosclerosis increases their risk of arrhythmia occurrence.

Key words：Dynamic index of atherosclerosis；Cardiac arrhythmias；High blood pressure

1 資料與方法

1.1一般資料 選擇2014年9月～2015年9月本院148例老年高血壓患者作為研究對(duì)象，根據(jù)（AASI）的差異分別設(shè)置對(duì)照組（低值組）及觀察組（高值組），每組74例，以0.49為中位數(shù)，對(duì)照組的AASI均不超過(guò)0.49，觀察組的AASI均大于0.49。對(duì)照組，男34例，女40例；年齡68～82歲。觀察組，男40例，女34例；年齡69～83歲。患者均接受相關(guān)臨床檢查，被診斷為高血壓患者，收縮壓均不小于140 mmHg或者舒張壓均不小于90 mmHg，均符合中國(guó)高血壓防治指南關(guān)于高血壓的診斷標(biāo)準(zhǔn)[1]。兩組患者一般資料比較差異無(wú)統(tǒng)計(jì)學(xué)意義（P>0.05），具有可比性。

1.2方法

1.2.1選擇由美國(guó)太空實(shí)驗(yàn)室提供的BPM監(jiān)測(cè)系統(tǒng)90207型針對(duì)患者血壓及心電圖開(kāi)展實(shí)時(shí)監(jiān)測(cè)，按照20 min/次針對(duì)患者6：00～22：00時(shí)間段內(nèi)的血壓水平進(jìn)行檢測(cè)和記錄，按照30 min/次針對(duì)患者22：00至次日6：00時(shí)間段內(nèi)的血壓水平進(jìn)行檢測(cè)和記錄，記錄時(shí)間不小于22 h，本次研究中有效測(cè)壓次數(shù)在總測(cè)壓數(shù)中占據(jù)的比例超過(guò)80%。……
