目的 探讨磁化矿泉浴对老干部左室Tei指数的影响。方法 将入院疗养的师团职老干部106例随机分为两个组,每组53例,观察组采用磁化矿泉浴,对照组采用矿泉浴,观察治疗前后左室Tei指数的变化情况。结果 治疗后两组Tei指数缩小,与治疗前比较差异有高度统计学意义(P<0.01),两组间差异不明显(P>0.05)。结论 磁化矿泉浴及矿泉浴均可提高师团职老干部左室整体功能。

磁化矿泉浴可以提高心血管功能,左室Tei指数能客观反映出左室收缩和舒张整体功能[1-3],本研究观察了磁化矿泉浴对师团职老干部左室Tei指数的影响。
1.1 研究对象 106例均为入院疗养的师团职老干部,男58例,女48例;年龄60~86岁,平均年龄70.5岁;随机分为两个组,每组53例。
1.2 仪器和方法 观察组采用磁化矿泉浴(将4块10 cm×5 cm×1 cm磁感应强度为180 mT的磁铁南北极对置于4 m×2 m×0.5 m浴池中的四角,磁处理30 min后取出磁铁马上进入洗浴),对照组采用单纯矿泉浴,水温均为38~40℃,20 min/次,1次/d,15次为一疗程。观察治疗前后左室Tei指数变化情况。仪器采用Aloka ssc 400彩色多普勒超声诊断仪,探头频率3.5 MHz,常规心脏扫查。分别测量左室舒张末期内径(LVDd),二尖瓣口血流频谱舒张早期和舒张晚期血流峰值之比(E/A),E峰减速时间(DT),左室射血分数(EF)和Tei指数。Tei指数为等容收缩期(ICT)与等容舒张期(IRT)之和除以射血时间(ET)Tei=(ICT+IRT)/ET。左室射血时间为B,二尖瓣口血流终止处到下一个心动周期二尖瓣口血流开始的时间为A,(ICT+IRT)/ET=(A-B)/B。计算方法为:在二尖瓣口血流频谱上从一个心动周期A峰终点测量到下一个心动周期E峰的起点(A)减去一个心动周期主动脉口血流开始到终止处的时间间隔(B),所得数值再除以B。多普勒信号以50~100 mm/s的速度记录,同时描记心电图连续三个心动周期取均值进行统计学处理。
经15 d磁化矿泉浴治疗,观察组与对照组Tei指数均明显缩小,与治疗前比较差异有高度统计学意义(P<0.01),治疗后两组间比较差异无统计学意义(P>0.05,表1)。
表1 师团职老干部磁化矿泉浴及矿泉浴前后左室Tei指数及有关心功能的变化
兴城矿泉中含有氡、氟、钙、硅、氯、钠等化学元素,属于氯化物泉及硅酸泉。由于矿泉水的温热、压力及各种离子的作用,可以加速血液循环,提高细胞膜的通透性,增加摄氧及耗氧能力,加速气体交换,促进最大摄氧水平,提高心血管功能[4-6]。经磁化的矿泉水由于磁场的作用,可以改变矿泉水的表面张力、粘度、离子形状、离子溶解度及渗透压等,从而有利于矿泉水的吸收,进一步提高心脏整体功能。
Tei指数又称心肌活动指数,是近年来评价心脏收缩与舒张整体功能的新指标[7-8],该指数不受心室几何形态、瓣膜返流及心率的影响,可以较客观反映出心脏收缩与舒张的整体功能[9-10]。此方法测量简便,敏感性好,准确率高。本研究表明,观察组经15 d治疗,Tei指数明显缩小,与治疗前比较差异有统计学意义,对照组治疗后Tei指数也明显缩小,但治疗后两组间差异不明显,表明磁化矿泉浴及矿泉浴均能提高师团职老干部心血管整体功能。

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.
