Abstract: Objective: To study the application value of nursing intervention in the coronary artery MSCTA check.Materials and Methods: 80 patients who were ready to received cornary artery MSCTA examinations,were randomly divided into control group(n=40) and the nursing intervention groups(n=40).Care in the control group only to oral metoprololg decreas heart rate,no other intervention measures,Care in the nursing intervention group,to take a series of nursing intervention measures,effectively reduce the heart rate(HR<70 bpm) and control of heart rate stability.Results: The control group: success in 25 cases,failure in 15 cases,the success rate is 62.50%(25/40),of which image quality was excellent in 13 cases,good in 5 cases,basically meet the needs of diagnosis in 7 cases,the excellent and good rate was 72%(18/25);the nursing intervention group: success in 38 cases,failure in 2 cases,the success rate is 95%(38/40),of which the image quality was excellent in 30 cases,good in 5 cases,basically meet the needs of diagnosis in 3 cases,the excellent and good rate was 92.11%(35/38).The success rate in two groups was significant difference(P<0.01),the image of good quality rate also had statistical significance(P<0.05).Conclusion: It can significantly improve the success rate;ensure the image quality and diagnostic excellent rate to take the nursing intervention before coronary CTA check.
