The goal of this observational study is to learn about in a total of approximately 2000 patients with cardiovascular disease recruited from about 25 participating sites in China with eGFR<60 ml/min/1.73 m2 and/or UACR>30 mg/g at least twice 3 months apart within the previous 12 months who had been hospitalized in the cardiology department within the previous 12 months. The main questions it aims to answer are:

• To estimate the diagnosis rate of CKD in patients with cardiovascular disease and laboratory evidence of CKD
• To describe the CKD awareness and treatment pattern in patients with cardiovascular disease and laboratory evidence of CKD.
• To describe the socio-demographic and clinical characteristics of CKD in patients with cardiovascular disease and laboratory evidence of CKD

Participants will be invited to undergo a baseline visit, and the demographics, lifestyle factors, clinical characteristics, and laboratory tests will be collected.

Inclusion Criteria:

1. Female and/or male aged ≥18 years
2. Admitted to the cardiology department with diagnosed cardiovascular disease within the previous 12 months
3. Participants with eGFR<60 ml/min/1.73 m2 and/or UACR>30 mg/g at least twice 3 months apart within the previous 12 months

Exclusion Criteria:

1. Participants with known eGFR<20 ml/min/1.73 m2 or undergoing dialysis or kidney transplantation
2. Pregnant or lactating women
3. Exposure to contrast medium or other reason leading to potential acute kidney injury since the baseline examination of eGFR/UACR
4. Patients who were participating in or had participated in any other clinical trial within the previous 12 months
