左心形态与冠状动脉狭窄程度的关系

Relationship between left ventricular morphology and severity of coronary artery stenosis

目的研究冠状动脉狭窄程度及分型与左心形态的关系。方法对选择性冠状动脉造影的589例住院患者,去除风湿性心脏病、高血压性心脏病后,进行冠状动脉病变程度与左心形态及收缩功能关系的分析。并使用Spss11.0统计软件分析包进行数据的R×C表卡方检验、均值的t检验(Independent-Sample T Test)、One-Way ANOVA方差分析和相关性分析(Bivariate Correlation)。结果冠状动脉病变积分、病变支数、病变分型与左房收缩末期内径(LADs)、左房舒张末期内径(LADd)、左室收缩末期内径(LVDs)、左室舒张末期内径(LVDd)呈正相关(P<0.01)。冠状动脉造影阳性组中LADs、LADd、LVDs均值增高。而且冠状动脉病变支数越多及冠状动脉狭窄介入治疗的难度越高,LADs、LADd、LVDs、LVDd的均值升高越明显。结论冠状动脉狭窄可引起心脏扩大,并随着狭窄程度的增高而加重。

Objective To study the relationship between the severity and type of coronary artery stenosis and left ventricular morphology. Methods 589 patients excluded rheumatic heart disease and hypertensive heart disease were selected to undergo coronary arteriongraphy.The relationship between the coronary artery lesion severity and the morpheus and systolic function of left ventricular was analyzed. Chi square test, independent-Sample T Test, One-Way ANOVA analysis of variance and bivariate correlation were performed with Spss statistical analysis software package. Results There was a positive correlation between Gensini scores, numbers of stenosed coronary vessel,stenosed type and the left atrium end systolic diameter（LADs）,lefl： atrium end diastole diameter（LADd）,left ventricular end systolic dimension（LVDs）, left ventricular end diastolic dimension（LVDd）（P〈0.01）. The mean value of LADs、LADd. LVDs was increased in the positive group of coronary arteriongraphy .The more number of stenosed vessel there were ,the more difficult the interventional therapy was, and the more higher the mean value of LADs、 LADd、 LVDs、 LVDd were. Conclusion Coronary artery stenosis can cause cardiac dilatation, which can be aggravated with the severity of stenosis.
