冠状动脉慢性完全闭塞病变成功介入治疗后心功能改善的影响因素. (Chinese)

目的：探讨冠状动脉慢性完全闭塞病变（CTO）患者介入治疗后心功能改善的影响因素。方法选择成功介入治疗冠状动脉 CTO 患者48例，根据介入治疗后9～12个月心功能变化分为改善组29例和未改善组19例，比较两组年龄，心绞痛病程，吸烟、高血压、糖尿病、血脂异常病史，血糖、血脂、血清 N 端脑钠肽前体（NT-proB-NP）等指标，以及冠脉病变、侧枝循环特点，分析影响介入治疗后心功能改善的因素。结果改善组年龄（48．6±6．1）岁，心绞痛病程（110．7±29．6）周，术前血清 NT-proBNP 水平为（230．20±58．30）pg／mL；未改善组年龄（61．4±10．3）岁，心绞痛病程（110．7±29．6）周，术前血清 NT-proBNP 水平为（403．90±81．10）pg／mL；两组年龄、心绞痛病程、术前血清 NT-proBNP 水平比较差异有统计学意义（P ＜0．01或＜0．05）。心功能改善组侧枝循环评分高于未改善组（P ＜0．05）。Logistic 回归分析显示，年龄较轻（OR ＝0．913，95％CI 0．769～0．985，P ＝0．031，）、心绞痛病程较短（OR ＝0．938，95％CI 0．893～0．984，P ＝0．010）是心功能改善的独立正向预测因素。结论年龄及心绞痛病程对冠状动脉 CTO 患者术后心功能改善有显著影响。 [ABSTRACT FROM AUTHOR]
