Clinical Value Study of Intravascular Ultrasound in the Diagnosis and Treatment of Coronary Intervention in Complex and High-risk Patients
Objective:To explore the clinical value of intravascular ultrasound(IVUS)in the diagnosis and treatment of coronary intervention in complex and high-risk patients.Method:A retrospective collection of clinical data was conducted on 285 complex high-risk patients who underwent coronary intervention treatment admitted to Huadu District People's Hospital of Guangzhou from January 2016 to January 2022,they were divided into coronary angiography(CAG)group(n=142)and IVUS group(n=143)based on the patient examination method.The operation-related indicators(successful patency rate of diseased vessels,complete revascularization rate,operation time),stent implantation(number of stent implantation,stent diameter,stent length,balloon diameter),incidence of operation-related complications,and major adverse cardiovascular events(MACE)during hospitalization were compared between the two groups.And the Killip cardiac function grading,ejection fraction(EF),readmission rate,compliance,review CAG status,and mortality rate due to cardiovascular disease within one year were calculated for two groups of patients who were followed up for 1 year.Result:There were no statistical significant differences in the successful patency rate of diseased vessels,complete revascularization rate,operation time,number of stents inserted,incidence of perioperative complications,MACE during hospitalization,review CAG at 1 year,and mortality rate due to cardiovascular disease within 1 year between the two groups(P>0.05);the diameter and length of stent in the IVUS group were longer than those of the CAG group,while the diameter of the dilated balloon and the readmission rate at 1 year follow-up were lower than those of the CAG group,and the Killip cardiac function grade,EF,and compliance in the IVUS group were higher than those in the CAG group at 1 year follow-up,the differences were statistically significant(P<0.05).Conclusion:IVUS can achieve similar diagnostic and therapeutic effects as CAG in the successful patency rate of diseased vessels and complete revascularization rate in complex and high-risk patients with coronary intervention,and has no significant impact on operation time,incidence of perioperative complications and MACE.At the same time,it can optimize stent placement,improve long-term cardiac function,and readmission rate of patients.
