A Cholesterol Lowering Therapy of Focused Power Ultrasound Mediated Perirenal Fat Ablation

Inclusion Criteria: 1. Males and Females aged 18-70 years old. 2. Each side of caudal perirenal fat volume \>8000mm3（measured by ultrasound). 3. Low and medium-risk of arteriosclerotic cardiovascular disease (ASCVD) with 3.4 ≤ LDL-C \< 4.9 mmol/L or 5.2 ≤ TC \< 7.2 mmol/L, as defined by the Chinese guidelines for the management of dyslipidemia in adults(revised edition 2016). 4. Participants should be willing to sign the informed consent form of the study. Exclusion Criteria: 1. Familial hyperlipidemia. 2.
