磁化礦泉?。焕细刹?;左室Tei指數(shù)
磁化礦泉浴可以提高心血管功能,左室Tei指數(shù)能客觀反映出左室收縮和舒張整體功能[1-3],本研究觀察了磁化礦泉浴對師團(tuán)職老干部左室Tei指數(shù)的影響。
1.1 研究對象 106例均為入院療養(yǎng)的師團(tuán)職老干部,男58例,女48例;年齡60~86歲,平均年齡70.5歲;隨機(jī)分為兩個組,每組53例。
1.2 儀器和方法 觀察組采用磁化礦泉浴(將4塊10 cm×5 cm×1 cm磁感應(yīng)強(qiáng)度為180 mT的磁鐵南北極對置于4 m×2 m×0.5 m浴池中的四角,磁處理30 min后取出磁鐵馬上進(jìn)入洗浴),對照組采用單純礦泉浴,水溫均為38~40℃,20 min/次,1次/d,15次為一療程。觀察治療前后左室Tei指數(shù)變化情況。儀器采用Aloka ssc 400彩色多普勒超聲診斷儀,探頭頻率3.5 MHz,常規(guī)心臟掃查。分別測量左室舒張末期內(nèi)徑(LVDd),二尖瓣口血流頻譜舒張早期和舒張晚期血流峰值之比(E/A),E峰減速時間(DT),左室射血分?jǐn)?shù)(EF)和Tei指數(shù)。Tei指數(shù)為等容收縮期(ICT)與等容舒張期(IRT)之和除以射血時間(ET)Tei=(ICT+I(xiàn)RT)/ET。左室射血時間為B,二尖瓣口血流終止處到下一個心動周期二尖瓣口血流開始的時間為A,(ICT+IRT)/ET=(A-B)/B。計算方法為:在二尖瓣口血流頻譜上從一個心動周期A峰終點測量到下一個心動周期E峰的起點(A)減去一個心動周期主動脈口血流開始到終止處的時間間隔(B),所得數(shù)值再除以B。多普勒信號以50~100 mm/s的速度記錄,同時描記心電圖連續(xù)三個心動周期取均值進(jìn)行統(tǒng)計學(xué)處理。
經(jīng)15 d磁化礦泉浴治療,觀察組與對照組Tei指數(shù)均明顯縮小,與治療前比較差異有高度統(tǒng)計學(xué)意義(P<0.01),治療后兩組間比較差異無統(tǒng)計學(xué)意義(P>0.05,表1)。
表1 師團(tuán)職老干部磁化礦泉浴及礦泉浴前后左室Tei指數(shù)及有關(guān)心功能的變化
興城礦泉中含有氡、氟、鈣、硅、氯、鈉等化學(xué)元素,屬于氯化物泉及硅酸泉。由于礦泉水的溫?zé)?、壓力及各種離子的作用,可以加速血液循環(huán),提高細(xì)胞膜的通透性,增加攝氧及耗氧能力,加速氣體交換,促進(jìn)最大攝氧水平,提高心血管功能[4-6]。經(jīng)磁化的礦泉水由于磁場的作用,可以改變礦泉水的表面張力、粘度、離子形狀、離子溶解度及滲透壓等,從而有利于礦泉水的吸收,進(jìn)一步提高心臟整體功能。
Tei指數(shù)又稱心肌活動指數(shù),是近年來評價心臟收縮與舒張整體功能的新指標(biāo)[7-8],該指數(shù)不受心室?guī)缀涡螒B(tài)、瓣膜返流及心率的影響,可以較客觀反映出心臟收縮與舒張的整體功能[9-10]。此方法測量簡便,敏感性好,準(zhǔn)確率高。本研究表明,觀察組經(jīng)15 d治療,Tei指數(shù)明顯縮小,與治療前比較差異有統(tǒng)計學(xué)意義,對照組治療后Tei指數(shù)也明顯縮小,但治療后兩組間差異不明顯,表明磁化礦泉浴及礦泉浴均能提高師團(tuán)職老干部心血管整體功能。

Objective To explore the influence of magnetized mineral bath on left ventricular Tei index of military division veteran cadres.Methods A total of 106 military division veteran cadres hospitalized for recuperation in the sanatorium were divided into two groups at random,with 53 in each group.The observation group took magnetized mineral bath while the control group took mineral bath.The changes of left ventricular Tei index before and after the treatment were observed.Results After treatment,the Tei index of both groups decreased.The differences between before and after the treatment were of high statistical significance(P<0.01).There was not clear difference in the Tei index between the two groups(P>0.05).Conclusion Both magnetized mineral bath and mineral bath can improve the left ventricular integrated function of military division veteran cadres.
