冠脉CTA失败的相关因素及二次检查护理干预

The related factors of coronary CTA failure and nursing intervention of the second examination

目的总结冠脉CT血管造影(CTA)失败的相关因素并探讨二次检查护理干预策略。方法选取行冠脉CTA检查的70例冠心病患者作为研究对象,依据冠脉CTA成功与否分为对照组(冠脉CTA成功)50例及观察组(冠脉CTA失败)20例,对导致冠脉CTA失败的相关因素进行总结并探讨二次检查护理干预策略。结果 2组患者性别、年龄、病程时间、病变程度、病变部位、症状表现差异无统计学意义(P>0.05),血压、心率、呼吸、造影剂推注速率相比较差异有统计学意义(P<0.05);Logistic分析结果提示,心率、呼吸为导致冠脉CTA失败的独立风险因素(P<0.05)。结论心率、呼吸为导致冠脉CTA失败的独立风险因素,给予冠心病患者心理干预、呼吸训练、控制心率药物将有助于冠脉CTA二次检查的顺利实施。

Objective To summarize the related factors of coronary CT angiography （ CTA）, and to explore the nursing strategy of the second examination for patients with coronary artery disease （CTA）. Methods A total of 70 patients with coronary heart disease underwent coronary CTA exami- nation in our hospital were as research objects, and were divided into control group （coronary CTA success） with 50 cases and observation group （ coronary CTA failure） with 20 cases, related factors of CTA failure were summarized and the nursing intervention of the second examination was discussed. Results There was no significant difference in two groups in gender, age, disease duration, severity of symptoms, lesions location, and manifestations（P 〉 0.05 ） ; Blood pressure, heart rate, respiration, contrast agent injection rate showed significant difference （ P 〈 0.05 ） ; Logistic analysis results indica- ted that the heart rate and breathing independent were risk factors leading to coronary CTA failure （P 〈 0.05 ）. Conclusion Heart rate, and respiratory failure are independent risk factors for coronary CTA failure. Psychological intervention, breathing training, and heart rate controlling drugs will con- tribute to the successful implementation of coronary CTA for secondary examination.
