- A randomized, placebo-controlled trial in diabetic patients receiving hemodialysis showed no effect of atorvastatin on a composite cardiovascular endpoint, but analysis of the component cardiac endpoints suggested that atorvastatin may significantly reduce risk. Because the AURORA (A Study to Evaluate the Use of Rosuvastatin in Subjects on Regular Hemodialysis: An Assessment of Survival and Cardiovascular Events) trial included patients with and without diabetes, we conducted a post hoc analysis to determine whether rosuvastatin might reduce the risk of cardiac events in diabetic patients receiving hemodialysis. Among the 7:31 participants with diabetes, traditional risk factors such as LDL-C, smoking, and BP did not associate with cardiac events (cardiac death and nonfatal myocardial infarction). At baseline, only age and high-sensitivity C-reactive protein were independent risk factors for cardiac events. Assignment to rosuvastatin associated with a nonsignificant 16.2% reduction in risk for the AURORA trial's composite primary endpoint of cardiac death, nonfatal MI, or fatal or nonfatal stroke (HR 0.84; 95% CI 0.65 to 1.07). There was no difference in overall stroke, but the rosuvastatin group had more hemorrhagic strokes than the placebo group (12 versus two strokes, respectively; HR, 5.21; 95% CI 1.17 to 23.27). Rosuvastatin treatment significantly reduced the rates of cardiac events by 32% among patients with diabetes (HR 0.68; 95% CI 0.51 to 0.90). In conclusion, among hemodialysis patients with diabetes mellitus, rosuvastatin might reduce the risk of fatal and nonfatal cardiac events.

- Obese patients are prone to arterial hypertension, require more antihypertensive medications, and have an increased risk of treatment-resistant arterial hypertension. Obesity-induced neurohumoral activation appears to be involved. The association between obesity and hypertension shows large inter-individual variability, likely through genetic mechanisms. Obesity affects overall cardiovascular and metabolic risk; yet, the relationship between obesity and cardiovascular risk is complex and not sufficiently addressed in clinical guidelines. The epidemiological observation that obesity may be protective in patients with established cardiovascular disease is difficult to translate into clinical experience and practice. Weight loss is often recommended as a means to lower blood pressure. However, current hypertension guidelines do not provide evidence-based guidance on how to institute weight loss. In fact, weight loss influences on blood pressure may be overestimated. Nevertheless, weight loss through bariatric surgery appears to decrease cardiovascular risk in severely obese patients. Eventually, most obese hypertensive patients will require antihypertensive medications. Data from large-scale studies with hard clinical endpoints on antihypertensive medications specifically addressing obese patients are lacking and the morbidity from the growing population of severely obese patients is poorly recognized or addressed. Because of their broad spectrum of beneficial effects, renin-angiotensin system inhibitors are considered to be the most appropriate drugs for antihypertensive treatment of obese patients. Most obese hypertensive patients require two or more antihypertensive drugs. Finally, how to combine weight loss strategies and antihypertensive treatment to achieve an optimal clinical outcome is unresolved.

- Background: Haemodialysis patients are at high risk for cardiovascular (CV) events. The aim of the current study was to characterise the role of traditional and uraemia-specific CV risk factors in this patient population. Methods: A post hoc analysis of the AURORA trial which enrolled 2,776 haemodialysis patients from 280 centres and had a mean follow-up period of 3.2 years. Determinants of CV endpoints (time to major cardiovascular event (MACE), cardiac event, CV death) were identified by univariate Cox regression analysis. Subsequently, independent determinants were identified by multivariate regression analysis. Results: For the primary endpoint MACE (myocardial infarction, stroke and cardiac death), multivariate analysis revealed that independent determinants were: age (hazard ratio (HR) 1.03 per year), serum phosphate level (HR 1.50 per mmol/l), albumin level (HR 0.94 per gip, years on haemodialysis (HR 1.03 per year), diabetes mellitus (HR 1.38), preexisting coronary heart disease (HR 1.54) and C-reactive protein (CRP) level (HR 1.14 per mg/l). However, conventional risk factors such as smoking, dyslipidaemia, systolic and diastolic blood pressure and pulse pressure had no significant effect. Conclusions: Although we identify CRP, low albumin, and high phosphorus as risk factors for MACE, lowering CRP did not influence MACE outcomes in our trial. Caution is therefore warranted in implying risk factors being causal in end-stage renal disease.
