Критерии участия

Критерии включения

• Extremely high risk: LDL-C ≥ 70 mg/dL (1.8 mmol/L);

Without a history of ASCVD:

• Moderate to high risk: LDL-C ≥ 100 mg/dL (2.6 mmol/L);
• Low risk: LDL-C ≥ 130 mg/dL (3.4 mmol/L); 4.Participants are able to establish good communication with the investigator and complete the trial in accordance with the protocol.

• Treatment with PCSK9 monoclonal antibodies or oral PCSK9 inhibitors within the past 180 days before screening or treatment with incisiran or any other RNA-based lipid-lowering therapy within the past 2 years before screening;
• History of malignancy within 5 years (excluding treated basal cell carcinoma of the skin), or presence of a suspected malignancy currently being evaluated by the investigator;
• Systolic blood pressure (SBP) > 180 mmHg or diastolic blood pressure (DBP) > 110 mmHg during the Screening Period or prior to Randomization;
• History of heart failure with NYHA Class III-IV within 180days before screening or prior to Randomization, or LVEF < 40% within 180 days before screening;
