They were clinically stable, without evidence of clinical heart failure at the time of inclusion (defined as dyspnoea plus two of the following conditions: increased jugular venous pressure, bibasilar rales, pulmonary venous hypertension, interstitial oedema requiring admission, extra ultrafiltration, or an ejection fraction < 35%), of both sexes, aged 18 and over, and agreed to participate in the study.

Blood draws were taken before the second or third HD session of the week, after 20-30 minutes of rest in a supine decubitus position. Laboratory testing for clinical follow-up was performed for these patients (blood urea nitrogen [BUN], calcium, phosphate, albumin, PTHi, haemoglobin, ferritin, C reactive protein [PCR], Kt/V), and additional special testing included: lipoprotein(a), homocysteine, asymmetric dimethylarginine (ADMA), advanced oxidation protein products (AOPP), malondialdehyde (MDA), troponin-I, brain natriuretic peptide (BNP), osteoprotegerin, fetuin, and adiponectin. A subgroup of 120 unselected patients also underwent an echocardiogram, and 87 underwent a Doppler ultrasound of the supra-aortic trunks.</p><p class="elsevierStylePara"> The echocardiogram measured the telediastolic and telesystolic sizes of the ventricles in order to calculate the ejection fraction and measured wall thickness in order to calculate the left ventricular mass, based on the Penn convention, and it was normalised for body surface area. The Doppler ultrasound of the supra-aortic trunks evaluated the primitive carotid, the carotid bifurcation, and the origin of the internal carotid bilaterally. In addition, the prebifurcation carotid intima-media thickness was measured; four measurements were obtained and the mean was calculated. A normal value of ≤ 0.9mm was used, based on the 2007 Consensus Hypertension Guidelines from the ESH/ESC.<span class="elsevierStyleSup">20 </span></p><p class="elsevierStylePara"> Homocysteine was determined by immunoassay in an Advia-Centaur autoanalyser (Siemens Spain, Barcelona), using reactants from the manufacturer. CRP was quantified by nephelometry (BNII Siemens Spain, Barcelona), and troponin-I by chemiluminescence immunoassay (TnI Ultra, Siemens Spain, Barcelona) in an Advia-Centaur autoanalyser (Siemens). BNP levels were also determined through chemiluminescence immunoassay (BNP, Siemens Spain, Barcelona) in an Advia-Centaur autoanalyser (Siemens).</p><p class="elsevierStylePara"> Lipoprotein(a) was determined with immunoturbidimetry (Dia-Sorin, Barcelona, Spain), and the levels of ADMA by HPLC.

The mean of Charlson comorbidity index was 5.67 ± 2.47 points and 25.66% of patients had a history of a previous renal transplant.</p><p class="elsevierStylePara"> The most common etiologies of renal failure were vascular and diabetic, with 17.7% of cases for each one, followed by glomerulonephritis in 17.4%, unknown cause in 16.2%, polycystic kidneys in 12.8%, chronic interstitial nephropathy in 9.4%, and other causes in 8.7% of cases.</p><p class="elsevierStylePara"> The prevalence of CVD was 52.8%. 44.9% percent of patients had cardiac pathology and 25.3% had non-cardiac vascular disease (cerebrovascular disease or peripheral vasculopathy), as shown in Table 1. On analysis of the presence of classic CVRF, tobacco use (active and exsmokers) was present in 41.5% of cases (16.6 and 24.9%, respectively). 26.8% of patients had a history of diabetes mellitus and 35.8% had a history of dyslipidaemia. The high prevalence of hypertension in 86.8% of subjects is notable. When the average weekly pre-dialysis blood pressure was analysed, 31.4% had a systolic pressure > 140mmHg and 3.8% had a diastolic pressure > 90mmHg. Pulse pressure was > 60mmHg in 42.3% of cases. 19.9% of patients received treatment with angiotensin converting enzyme inhibitors (ACE-I) or with angiotensin II receptor blockers (ARB) and the same percentage received beta-blocker treatment. In the subgroup of patients with coronary disease, 13.7% received ACE-I/ARB treatment while 35.3% received beta-blockers. In the global population, 26.8% received antiplatelet therapy and 6.9% received anticoagulant therapy. Of those patients with coronary disease, 41.4% received antiplatelet therapy and 10% received anticoagulants. Among diabetic patients, 38% received antiplatelet treatment and 7% received anticoagulants.</p><p class="elsevierStylePara"> Among the classic risk factors (table 2), 12.9% had elevated cholesterol levels (> 200mg/dl), 29.5% had cLDL > 100mg/dl, 43.5% had cHDL < 40mg/dl, and 30.5% had TG > 150mg/dl. 24.1% of patients received statin therapy but among those with cLDL > 100mg/dl, only 33.8% received that treatment. Only 38.4% of patients with diabetes mellitus and cLDL > 100mg/dl received statins and 57.69% of those with a history of CVD and cLDL > 100mg/dl received them. The presence of high levels of new CVRF was also common in the patients, as seen in table 2. Markers of inflammation and malnutrition, such as CRP (> 0.8mg/dl), were elevated in 40.7% of patients, IL-6 (> 5pg/ml) in 82.3%, albumin (< 40g/l) in 39.1%, fibrinogen (> 4.5g/l) in 43%, lipoprotein(a) (> 30mg/dl) in 36%, troponin-I (> 0.1ng/ml) in 6.3%, and homocysteine (> 15mmol/l) in 89.4%. 23.2% had haemoglobin levels < 11g/l and 30.9% had a Ca x P product greater than 55mg<span class="elsevierStyleSup">2</span>/dl<span class="elsevierStyleSup">2</span>, with calcium and phosphate levels elevated at 34.6 and 65.6%, respectively, based on criteria from the KDOQI guidelines.</p><p class="elsevierStylePara"> In assessing the prevalence of subclinical CVD, we observed that 74% of the patients with an echocardiogram had LVH and that 7.6% had an ejection fraction of < 40%. Of the patients with carotid Doppler ultrasounds, 25.3% had increased carotid intima-media thickness (> 0.9mm). In the univariate analysis, the factors associated with CVD, as seen in tables 3 and 4, were age, body mass index, history of hypertension, dyslipidaemia, and diabetes mellitus, previous time on HD, Charlson’s comorbidity index, elevated levels of fibrinogen and BNP, carotid intima-media thickness, left ventricular mass, and pulse pressure. The following factors were negatively associated with the presence of CVD: history of previous renal transplant, cardiac ejection fraction, and low levels of cLDL and phosphate.</p><p class="elsevierStylePara"> In the multivariate analysis, the factors associated with CVD were age, dyslipidaemia, LVH, and negatively the level of cLDL, as shown in Table 5. By ROC analysis, these factors predicted CVD prevalence with a value of 0.736 (95% CI: 0.675-0.797). (Figure 1). <span class="elsevierStyleBold"> </span></p><p class="elsevierStylePara"><span class="elsevierStyleBold"> </span></p><p class="elsevierStylePara"><span class="elsevierStyleBold">DISCUSSION </span></p><p class="elsevierStylePara"> </p><p class="elsevierStylePara">The results of this study, carried out in a population of patients with CKD on HD, emphasize the high prevalence of CVD, which is consistent with results from other similar series. This would explain, in part, the high incidence of fatal and non-fatal cardiovascular pathology in these patients. Furthermore, the prevalence of subclinical CVD (LVH or increased carotid intima-media thickness), as well as of classic and new CVRF is high in this unselected population of patients on HD.</p><p class="elsevierStylePara"> The elevated cardiovascular risk in patients on HD is much higher to that of the general population, and even to other groups of patients recognised to have high cardiovascular risk (e.g., diabetics or hypertensives). This is in part explained by the high prevalence of CVD, both clinical and subclinical. In the univariate analysis, the factors associated with the presence of CVD were age, the presence of subclinical CVD or classic CVRF, markers of inflammationmalnutrition, or markers of cardiac disease, such as BNP. In the multivariate analysis, only some classic CVRF and LVH maintained their predictive value.</p><p class="elsevierStylePara"> The apparent discrepancy between the predictive value of dyslipidaemia and the lowest levels of cLDL may be explained in several ways. The clinical history of dyslipidaemia included hypercholesterolaemia, but also low levels of cLDL or hypertriglyceridaemia (the latter two being more common in kidney patients); on the other hand, patients with CVD were more often given statins and, lastly, low levels of cLDL may be associated with inflammation-malnutrition (another recognised CVRF in this population).</p><p class="elsevierStylePara"> These data reinforce the predictive role of classic CVRF for the prediction of CVD in patients on HD. An interesting finding in the univariate analysis was that patients with CVD had significantly higher levels of osteoprotegerin. In recent years there has been a growing interest in the possible role of abnormalities in mineral metabolism, in its markers (e.g., osteoprotegerin, fetuin, or FGF-23), or in the vascular calcifications on cardiovascular morbidity and mortality in patients on HD. Therefore, a relationship between elevated levels of osteoprotegerin and vascular calcification and mortality has been described in these patients.<span class="elsevierStyleSup">22 </span>Although the predictive role of OPG was lost in the multivariate analysis, our results add to the association between this marker and CVD in these patients.</p><p class="elsevierStylePara"> Another aspect of our study that is important to draw attention is the poor CVRF control and scarce use of treatments with demonstrated CV protective effects in the non-uraemic population (RAAS inhibitors, statins, antiplatelet agents) in our population even among patients with diabetes or CVD, similar to what has been described in the literature.<span class="elsevierStyleSup">23 </span>This low CVRF control and a certain “therapeutic nihilism” that is detected in our study may contribute to elevated morbidity and mortality in patients on HD. This may be due, in part, to polypharmacy, which hinders therapeutic compliance and facilitates therapeutic inertia, in addition to the scant evidence of the beneficial effects of the aforementioned treatments in reducing the risk of events in patients on HD.<span class="elsevierStyleSup">9,10,24 </span></p><p class="elsevierStylePara"> To conclude, the prevalence of clinical and subclinical CVD is very high in our population of patients on HD. Furthermore, the prevalence of classic and new CVRF is also high. The factors predictive of clinical CVD in our population were age and the presence of subclinical CVD (LVH) and classic CVRF. Furthermore, controlling CVRF and using cardioprotective medications in this general population is not sufficient, according to recommendations from the various clinical practice guidelines for these patients. Efforts must be made for early and aggressive treatment (in the pre-dialysis stage) of the CVRF in these patients in order to try to reduce their high CV morbidity and mortality.  </p><p class="elsevierStylePara"><a href="grande/10443_18030_5605_en_table1.jpg" class="elsevierStyleCrossRefs"><img src="10443_18030_5605_en_table1.gif" alt="Distribution of cardiovascular pathology in the population"></img></a></p><p class="elsevierStylePara">Table 1.
