Abstract:
Objective To compare the therapeutic effect of intravascular ultrasound-guided(IVUS-guided)shockwave balloon and cutting balloon in the treatment of severe coronary artery lesions.Methods The clinical data of 180 patients with coronary artery calcified lesions,who were admitted to the Affiliated Zhengzhou Municipal Seventh People's Hospital of Southern Medical University and the Affiliated Henan Provincial Chest Hospital of Zhengzhou University of China from January 2021 to December 2022,were retrospectively analyzed.Using the random number table method,the patients were divided into study group(n=90,receiving IVUS-guided shockwave balloon technology)and control group(n=90,receiving IVUS-guided cutting balloon technology).The surgical outcomes and 24-month follow-up prognosis were compared between the two groups.Results The mean medical cost in the study group was higher than that in the control group(P＜0.05).After pretreatment,the plaque load in the study group was lower than that in the control group,while the minimum lumen diameter,minimum lumen area inside the stent,and stent expansion rate in the study group were all greater than those in the control group(all P＜0.05).One month after treatment,the patients of both groups showed a significant increase in left ventricular ejection fraction(LVEF)and a significant decrease in left ventricular end diastolic diameter(LVEDd)(both P＜0.05),but there were no statistically significant differences in the above two indicators between the two groups(both P＞0.05).The median survival time without adverse cardiovascular events(MACE)in the study group was longer than that in the control group(P＜0.05).Conclusion For the treatment of coronary artery calcified lesions,the IVUS-guided shockwave balloon technique has a certain and reliable therapeutic effect,the postoperative lumen area of the target vessel is larger,and the long-term prognosis is better,when compared with the IVUS-guided cutting balloon technique.
