Abstract：Objective To study the clinical effect of intravascular low frequency and high energy ultrasound ablation for atherosclerotic plaque patients. Methods From August 2015 to March 2017, the clinical data of 64 patients with atherosclerotic plaque in the First Affiliated Hospital of Hebei North University were retrospectively analyzed, and they were divided into two groups according to the treatment method, the study group was given intravascular low frequency and high energy ultrasound ablation, the control group was given percutaneous transluminal coronary angioplasty. The clinical effect, complication and recurrence of two groups were compared. Results Before the treatment, the stenosis degree in two groups was compared, the difference was not statistically significant (P > 0.05), after the treatment, the stenosis degree in two group reduced significantly, and this in study group was lower than control group, the differences were statistically significant (P < 0.01); the balloon pressure and dilation time in study group were lower than those in control group, the differences were statistically significant (P < 0.01). Before the treatment, experiment sport results in two groups were compared, the difference was not statistically significant (P > 0.05); after treatment, two groups were improved statistically, and the time of angina pectoris and ST segment in study group decreased more significantly than control group, the differences were statistically significant (P < 0.01). The total effective rate in study group was higher than control group, the complication rate and recurrence rate in study group were lower than control group, the differences were statistically significant (P < 0.05). Before the treatment, the heart function classification in two groups were compared, the difference was not statistically significant (P > 0.05); after the treatment, the ratio of cardiac function Ⅰ and Ⅱ in study group was higher than control group, the difference was statistically significant (P < 0.01). Conclusion Patients with atherosclerotic plaque are better treated with intravascular low frequency and high energy ultrasound ablation will have better effects, it can effectively improve the degree of coronary artery stenosis in patients, promote cardiac function to return to normal, avoid complications and recurrence, alleviate the symptoms of angina pectoris, promote the rapid and stable condition, provide protection for the prognosis.
