    Abstract:
    OBJECTIVE: To identify the risk factors associated with cardiovascular disease (CVD) in Chinese chronic kidney disease (CKD) patients. METHODS: As part of a multicenter Chinese cohort study, the clinical data associated with CVD of 1239 patients with CKD (stage 2 - 5) hospitalized in 7 grade 3A hospitals distributed in 5 regions of China 2002 - 2003 were collected. Logistic regression model was used to analyze the association between CVD and the demographic variables, lifestyle, medical history, medication, physical examination, and laboratory variables. RESULTS: (1) Increase of serum C-reactive protein (CRP, cut off > 10 mg/L) was an independent risk factor for development of coronary artery disease (CAD) (OR 2.13; 95% confidence interval [CI], 1.32 - 3.43). 21.5% of the patients in this group showed a value of CRP > 10 mg/L. (2) Being female, anemia, and systolic hypertension were the major determinants of the development of left ventricular hypertrophy (OR 2.99, CI 2.09 - 4.26; OR 2.66, CI 1.19 - 3.57; and OR 1.02, CI 1.00 to -1.02). 54.2% of the patients in this group had their systolic pressure controlled under 140mmHg, and only 15% of the patients in this group had their hemoglobin remain at the level >or= 110 g/L. (3) There was a significant interaction between the calcium-phosphate product and congestive heart failure (CHF) (OR 1.023, CI 1.01 - 1.03). 25.9% of the patients in this cohort had their calcium-phosphate product >or= 55. (4) Hypoalbuminemia (OR 6.01, CI 1.25 - 28.96) and diastolic hypertension (OR 1.05, CI 1.00 - 1.09) played major role in determining cerebrovascular accidents (CVA). In these cohort the prevalence of hypoalbuminemia was 37.3%. (5) Diabetes was associated with CAD (OR 2.34), CHF (OR 1.97), and CVA (OR 4.40), although its prevalence was lower in Chinese CKD patients (20%). Age was the risk factors of CAD (OR 1.04) and CVA (OR 1.22). Hypertension was associated with LVH (OR 1.016), CHF (OR 1.02), and CVA (OR 1.04). CONCLUSION: CKD is associated with nontraditional risk factors for the development of CVD, including chronic inflammation, malnutrition and calcium-phosphate disorders. Particular care must be taken to give optimal treatment for the most important CVD risk factors active in Chinese CKD patients, e.g. anemia and hypertension.
