目的观察不同年龄的冠心病患者支架术前后QTd的变化特点与趋势,探讨年龄对支架术后QTd的影响.方法将260例冠心病患者按年龄分为：青年组（年龄≤44岁）、中年组（年龄45～59岁）、老年前期组（年龄60～74岁）、老年组（年龄≥75岁）四组.测量各年龄组术前及术后1d、术后1周的QTd,并进行比较.结果1.与术前比较,术后各年龄组QTd均减少.2.随着年龄增加术后QTd的缩短程度显著降低.结论1.成功的介入治疗可缩短QT离散度.2.随着年龄增加术后QTd的缩短程度呈下降趋势.
Objective To observe the QTd change characteristics and trends before and after stem in patients with coronary artery disease in different age, to investigate the influence of age on QTd after stenting. Methods 260 patients with coronary heart disease were divided into： young group （age〈44）, middle age group （45-59 years old）, aged group （aged 60-74 years）, aged group （aged〉75years）. QTd 1 days, 1 week after the operation measurement for each age group of preoperative and postoperative, and compare. Results 1.Compared with the preoperative, postoperative QTd of each age group were reduced. 2. Along with the age increase, the degree of QTd after operation can significantly reduce.
