COLLADO NIETO, Silvia et al. Prevalence of cardiovascular disease in uraemia and relevance of cardiovascular risk factors. Nefrología (Madr.) [online]. 2010, vol.30, n.3, pp.342-348. ISSN 1989-2284.

Aim: To evaluate the prevalence of cardiovascular disease (CVD) and its association with cardiovascular risk factors, as well as their control in end-stage renal disease (ESRD) patients under maintenance hemodialysis (HD). Patients and methods: A total of 265 patients with ESRD on maintenance HD from a University Hospital and 4 dialysis units were included in this multicenter and cross-sectional study that analyzed the prevalence of CVD and the possible association with classic and new cardiovascular risk factors. Usual biochemical and haemathological parameters were analyzed, as well as plasma levels of homocysteine, troponin-I, BNP, lipoprotein(a), C reactive protein, IL-6, fibrinogen, asymmetrical dimethylarginine (ADMA), advanced oxidation protein products (AOPP), malondialdehyde, adiponectin, osteoprotegerin, and fetuin. In a subset of patients an echocardiography and carotid artery Doppler echography were also performed. Results: The prevalence of CVD was 52.8%. Factors positively associated with prevalent CVD were age, BMI, left ventricular hypertrophy, hypertension, dyslipidemia and diabetes mellitus, dialysis vintage, Charlson's comorbility index, levels of fibrinogen, osteoprotegerin, BNP and CRP, as well as carotid intima-media thickness, left ventricular mass and pulse pressure. Factors negatively associated with prevalent CVD were: previous renal transplant, ejection fraction or levels of LDL-c and phosphorous. In the multivariate analysis dyslipidemia, left ventricular hypertrophy, age and LDL-c (negatively) were associated with CVD. Conclusions: In HD patients the prevalence of CVD is high and is associated with the presence of cardiovascular risk factors and subclinical CVD.
