急性心肌梗死患者PCI治疗后心动过缓发生情况分析

Analysis of bradycardia after PCI in patients with acute myocardial infarction

目的 分析急性心肌梗死(AMI)患者经皮冠状动脉介入(PCI)治疗后心动过缓发生的影响因素。方法 选择2019年1月—2021年3月焦作市人民医院收治的98例AMI患者为研究对象,患者均在本院接受PCI治疗,观察患者PCI后24 h内心动过缓发生情况并分组,分为发生组与未发生组,统计两组基线资料,通过logistic回归分析检验AMI患者PCI治疗后心动过缓发生的影响因素。结果 全部98例患者中,23例发生心动过缓,占23.47%;发生组右冠状动脉病变占比(65.22%)、合并糖尿病占比(52.17%)高于未发生组(38.67%、21.33%),入院时血清超敏C反应蛋白(hs-CRP)水平[(15.79±2.83)ng/L]高于未发生组[(11.46±2.46)ng/L],差异有统计学意义(P<0.05);经logistic回归分析结果显示,右冠状动脉病变、合并糖尿病、入院时血清hs-CRP高表达均为AMI患者PCI治疗后心动过缓发生的影响因素(P<0.05)。结论 右冠状动脉病变、合并糖尿病、入院时血清hs-CRP高表达均为AMI患者PCI治疗后心动过缓发生的影响因素。

Objective To analyze the influencing factors of bradycardia after percutaneous coronary intervention(PCI) in patients with acute myocardial infarction(AMI). Methods Totally 98 patients with AMI admitted to Jiaozuo People’s Hospital from January 2019 to March 2021 were selected as the study subjects. All patients received PCI treatment in our hospital. The occurrence of bradycardia within 24 hours after PCI was observed and divided into two groups: occurrence group and non occurrence group. The baseline data of the two groups were analyzed, and the influencing factors of bradycardia in AMI patients after PCI were examined by logistic regression analysis. Results Among all 98 patients, 23 had bradycardia, accounting for 23.47 %. The proportion of right coronary artery disease(65.22%) and the proportion of complicated diabetes(52.17%) in the occurrence group were higher than that in the non occurrence group(38.67% and 21.33%). The level of serum high-sensitivity C-reactive protein(hs-CRP) at admission [(15.79±2.83) ng/L] was higher than that in the non occurrence group [(11.46±2.46) ng/L], and the difference was statistically significant(P<0.05). The results of logistic regression analysis showed that right coronary artery disease, complicated with diabetes and high expression of serum hs-CRP at admission were the influencing factors of bradycardia after PCI in AMI patients(P<0.05). Conclusion Right coronary artery disease, complicated with diabetes and high expression of serum hs-CRP in patients with AMI after PCI are the influencing factors of bradycardia.
