摘要
目的探讨老年收缩期高血压左室肥厚的主要影响因素,阐释其HLVH与患者心肌缺血、心律失常及心衰间的相关性,为临床诊治及推广应用提供理论依据。方法将本次研究的所有患者依照其病情分为观察组(收缩期高血压左室肥厚老年患者)与对照组(单纯收缩高血压患者),并且所有患者均在停用降压药72h至96h间进行检查,使用超声心电图对LVPWT、IVST、LVID及心功能进行检查;使用动态心电监测系统对患者的心律失常、心肌缺血等情况进行实时监控并评价。结果对照组中共6例患者为心肌缺血,2例患者Ⅲ级以上室早;观察组中52例患者为心肌缺血,39例患者Ⅲ级以上室早,两组间存在显著性差异(P<0.05);与对照组相比,LVDD患者的LAD、IVST、LVPWT等指标显著性增加(P<0.05);但LVSD患者的LVID指标较对照组显著性扩大(P<0.05);LVDD与LVSD患者相比发现,LVDD患者LAD较LVSD患者显著性升高(P<0.05),但两组间差异明显小于LVID、LVST、LVPWT指标差异(P<0.01);评价左室收缩功能的CI及LVEF指标间在对照组和LVDD其组间差异无统计学意义(P>0.05),但LVSHF组患者的上述指标则呈现显著性降低(P<0.05);与对照组相比,LVDD组患者DC、E峰及E/A显著减低(P<0.05),但IRT与A峰指标则显著增高(P<0.05),但LVSD组与LVDD两组间上述指标无显著性差异(P>0.05)。结论在老年收缩期高血压左室肥厚患者中,心肌缺血、心律失常、心衰均与其存在着密切关系。
Objective Toexplore the main factors affecting the elderly systolic hypertension and left ventrieular hypertrophy, explains the HLVH and myocardial iscbemia in patients with, the correlation between arrhythmia and heart failure, for the clinical diagnosis and the application provides theoretical basis. Methods all of the patients in this study according to the disease affection for observation group （ systolic hypertension left ventrieular hypertrophy in senile patients） and control group （ simple systolic hypertension patients and all patients were in stopping antihypertensive drug 72h and 96h check, LVPWT, IVST, LVID and cardiac function were examined using echocardiography; make the patient＇s heart by means of the dynamic ECG monitoring system. Results inthe control group of 6 patients with myocardial ischemia, 2 patients with myocardial ischemia, two patients in the observation group, 12 patients with myocardial ischemia, 9 patients with P 〈0.05, LAD, P 〈0.05, IVST, LVDD, LVP- WT, LVSD, LVID, LVDD and LVDD patients, compared with the control group, LAD SD patients were significantly elevated （ P 〈0.05） , but the difference between the two groups was significantly less than LVID, LVST, LVPWT index difference （ P 〈 0.01 ） ;Assessment of left ventricular systolic function between CI and LVEF index in the control group and LVDD have no significantly difference between the groups （ P 〉0. 05 ） , but LVSHF group of the indicators are significantly lower （ P 〈 0.05 ） ; Group compared with control group, LVDD＇s DC, E and E/A significantly lower （ P 〈 0.05 ）, but in IRT and A peak index were significantly higher （P 〈 0.05）, however in LVSD group and LVDD the above indexes between the two groups have no significant difference （P 〉 0. 05 ）. Conclusion in elderly patients with systolic hypertension left ventricular hypertrophy, myocardial ischemia, arrhythmia, heart failure and its existence is closely related.
