    Abstract:
    OBJECTIVE: Cardiovascular (CV) disease (CVD) is the single most important cause of death among Chinese dialysis patients, accounting for 51% of overall mortality. The study was performed to investigate the prevalence and the spectrum of CVD in Chinese chronic kidney disease (CKD) patients. METHODS: The multicenter Chinese cohort study examined 1239 CKD patients from 7 main medical centers (distributed in 5 regions of China) who were hospitalized between 2002 and 2003. RESULTS: (1) The most prevalent pathological form of CVD was left ventricular (LV) hypertrophy (LVH), accounting for 58.5% of total patients. The prevalence of coronary artery disease (CAD), congestive heart failure (CHF), and cerebrovascular accidents (CVA) was 16.5%, 27.7% and 5.6%, separately. (2) The cohort with minor renal dysfunction (stage 2-3) had higher prevalence of CAD (5.9%) and CVA (1.0%) compared with general population in the same regions. Up to 41.2% of minor CKD patients were complicated with LVH, and 13.8% of them had clinical evidence of CHF. The prevalence of CAD, LVH and CHF increased as glomerular filtration decline. (3) The prevalence of CAD (20.0%) was much lower and the prevalence of CVA (5.4%) was higher in Chinese dialysis patients than that in American dialysis population. There was significant geographical variations in CAD prevalence, but it was not different between genders. CONCLUSION: The CV risk is significantly increased in patients with CKD. Even minor CKD has a major impact on the CV risk. The prevalence of CAD in Chinese dialysis patients is markedly lower than that in American dialysis population.
