[摘要] 目的 对冠心病合并2型糖尿病(T2DM)患者的临床特征表现进行系统探析。方法 将2017年5月—2018年5月该院诊治的55例冠心病合并T2DM患者纳入研究组，选取同期诊治的55例单纯性冠心病患者纳入对照组，对比分析两组临床表现，并比较冠脉造影特征和心率变异(HRV)时域指标。 结果 研究组患者治疗后空腹血糖(FPG)、餐后2 h血糖(2 hPG)均显著降低，与治疗前比较差异有统计学意义(P<0.05);研究组患者无症状性心肌缺血、高血压、高血脂的发生率均显著高于对照组(P<0.05);研究组病变冠脉以多支为主，且主要是弥漫性病变，与对照组比较，差异有统计学意义(P<0.05)。结论 冠心病合并T2DM患者存在高血压、高血脂及心肌缺血等表现，且冠脉病变以多支、弥漫性病变为主，易引起心率变化。
