    • There is a clear genetic contribution to the risk of cardiovascular diseases, and a composite genetic risk score (GRS) based on 27 single nucleotide polymorphisms (SNPs) was reported to predict risk of cardiovascular events in the general population. We aimed to evaluate this risk score in renal transplant recipients, a population with heightened cardiovascular risk, with a yet unknown genetic contribution. This article is protected by copyright.

  • Cerebrovascular events in renal transplant recipients
  • 2009
  • Ingår i: Transplantation. - 0041-1337 .- 1534-6080. ; 87:1, s. 112-7
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The incidence of stroke and risk factors for different subtypes of cerebrovascular (CBV) events in renal transplant recipients have not been examined in any large prospective controlled trial. METHODS: The Assessment of Lescol in Renal Transplantation was a randomized, double-blind, placebo-controlled study of the effect of fluvastatin (40-80 mg) daily on cardiovascular, and renal outcomes in renal transplant recipients. Patients initially randomized to fluvastatin or placebo in the 5 to 6 year trial was offered open-label fluvastatin in a 2-year extension to the original study. We investigated the incidence of stroke and risk factors for ischemic and hemorrhagic CBV events in 2102 renal graft recipients participating in the Assessment of Lescol in Renal Transplantation core and extension trial with a mean follow-up of 6.7 years. RESULTS: The incidence and type of CBV events did not differ between the lipid lowering arm and the placebo arm. A total of 184 (8.8%, 95% confidence interval 4.6-12.9) of 2102 patients experienced a CBV event during follow-up, corresponding to an incidence of 1.3% CBV event per year. The mortality for patients experiencing a hemorrhagic stroke was 48% (13 of 27), whereas the mortality for ischemic strokes was 6.0% (8 of 133). Diabetes mellitus, previous CBV event, age, and serum creatinine were independent risk factors for cerebral ischemic events. The risk of a hemorrhagic cerebral event was increased by diabetes mellitus, polycystic kidney disease, left ventricular hypertrophy, and systolic blood pressure. INTERPRETATION: Risk factors for CBV events in renal transplant recipients differ according to subtype.

  • Cardiovascular risk in renal transplantation
  • 2008

    • Renal transplant patients suffer from a higher risk of cardiovascular morbidity and mortality. The risk-factor spectrum is different from the general population; several risk factors are transplantation specific, and to a large extent dependent on the immunosuppressive drugs used to prevent rejection. Due to the complexity of the risk factors, the variable impact of each factor on different cardiovascular outcomes and the inter-relationships between risk factors, it is difficult to judge the overall cardiovascular risk in a single renal transplant patient. In this paper we review risk-factor data from the literature, limited to single risk factors and their impact on single cardiovascular outcomes. We believe that a cardiovascular risk calculator specific to the renal transplant population, which takes into account all the important risk factors for a cardiovascular event, based upon a high quality database such as the ALERT data set, may provide a solid guidance to means to assess the overall cardiovascular risk in renal transplant recipients.

  • Effect of rosuvastatin on outcomes in chronic haemodialysis patients : design and rationale of the AURORA study
  • 2005
  • Ingår i: Current Controlled Trials. - : Springer Science and Business Media LLC. - 1468-6708 .- 1468-6694. ; 6:1, s. 9-16
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Patients with end-stage renal disease (ESRD) are at high risk of cardiovascular events. Multiple risk factors for atherosclerosis are present in ESRD and may contribute to the increased risk of cardiovascular mortality in this population. In contrast to patients with normal renal function, the benefits of modifying lipid levels on cardiovascular outcomes in patients with ESRD on haemodialysis have yet to be confirmed in large prospective randomised trials. A study to evaluate the Use of Rosuvastatin in subjects On Regular haemodialysis: an Assessment of survival and cardiovascular events (AURORA) will be the first large-scale international trial to assess the effects of statin therapy on cardiovascular morbidity and mortality in ESRD patients on chronic haemodialysis. METHODS: More than 2,750 ESRD patients who have been receiving chronic haemodialysis treatment for at least 3 months have been randomised (1:1), irrespective of baseline lipid levels, to treatment with rosuvastatin 10 mg or placebo. The primary study endpoint is the time to a major cardiovascular event (first occurrence of cardiovascular death, non-fatal myocardial infarction or non-fatal stroke). Secondary endpoints include all-cause mortality, major cardiovascular event-free survival time, time to cardiovascular death, time to non-cardiovascular death, cardiovascular interventions, tolerability of treatment and health economic costs per life-year saved. Study medication will be given until 620 subjects have experienced a major cardiovascular event. CONCLUSION: Our hypothesis is that results from AURORA will establish the clinical efficacy and tolerability of rosuvastatin in patients with ESRD receiving chronic haemodialysis and guide the optimal management of this expanding population.

  • Renal dysfunction as a risk factor for mortality and cardiovascular disease in renal transplantation : experience from the Assessment of Lescol in Renal Transplantation trial
  • 2005
  • Ingår i: Transplantation. - : Lippincott, Williams and Wilkins. - 0041-1337 .- 1534-6080. ; 79:9, s. 1160-1163
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Renal-transplant recipients have shortened life expectancy primarily because of premature cardiovascular disease. Traditional and nontraditional risk factors for cardiovascular disease are prevalent in renal patients. In renal-transplant recipients, immunosuppressive therapy can be nephrotoxic and aggravate cardiovascular disease risk factors. Renal dysfunction has been established as a risk factor for cardiovascular disease and mortality in different populations. We evaluated the effects of baseline renal-transplant function on mortality and cardiovascular and renal endpoints in 1,052 placebo-treated patients of the Assessment of Lescol in Renal Transplantation trial. METHODS: All renal-transplant recipients were on cyclosporine-based immunosuppressive therapy. Follow-up was 5 to 6 years, and endpoints included cardiac death, noncardiovascular death, all-cause mortality, major adverse cardiac event (MACE), stroke, nonfatal myocardial infarction, and graft loss. RESULTS: Baseline serum creatinine was strongly and independently associated with increased cardiac, noncardiovascular, and all-cause mortality, as well as MACE and graft loss. Serum creatinine was not a risk factor for stroke or nonfatal myocardial infarction. CONCLUSIONS: Elevated baseline serum creatinine in renal-transplant recipients is a strong and independent risk factor for all-cause, noncardiovascular and cardiac mortality, MACE, and graft loss.

  • Renal dysfunction is a strong and independent risk factor for mortality and cardiovascular complications in renal transplantation
  • 2005
  • Ingår i: American Journal of Transplantation. - : Elsevier BV. - 1600-6135 .- 1600-6143. ; 5:8, s. 1986-1991

    • Renal transplant recipients (RTR) have shortened life expectancy, primarily due to premature cardiovascular disease (CVD). Traditional CVD risk factors are highly prevalent. In addition, several non-traditional risk factors may contribute to the high risk. The aim of the study was to evaluate the effects of renal dysfunction on mortality and cardiovascular complications in 1052 placebo-treated patients of the Assessment of LEscol in Renal Transplantation (ALERT) trial. Follow-up was 5-6 years and endpoints included cardiac death, non-cardiovascular death, all-cause mortality, major adverse cardiac event (MACE), non-fatal myocardial infarction (MI) and stroke. The effects of serum creatinine at baseline on these endpoints were evaluated. Elevated serum creatinine in RTR was a strong and independent risk factor for MACE, cardiac, non-cardiovascular, and all-cause mortality, but not for stroke or non-fatal MI alone. Serum creatinine was associated with increased mortality and MACE, independent of established CVD risk factors. Graft loss resulted in increased incidences of non-cardiovascular death, all-cause mortality, MACE and non-fatal MI. In conclusion, elevated serum creatinine is a strong risk factor for all-cause, non-cardiovascular and cardiac mortality, and MACE, independent of traditional risk factors, but not for stroke or non-fatal MI alone.

  • Beneficial effect of early initiation of lipid-lowering therapy following renal transplantation
  • 2005
  • Ingår i: Nephrology, Dialysis and Transplantation. - : Oxford University Press (OUP). - 0931-0509 .- 1460-2385. ; 20:5, s. 974-980
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Renal transplant recipients have a significantly reduced life expectancy, largely due to premature cardiovascular disease. The aim of the current analysis was to investigate the importance of time of initiation of therapy after transplantation, on the benefits of statin therapy. METHODS: 2102 renal transplant recipients with total cholesterol levels of 4.0-9.0 mmol/l were randomly assigned to treatment with fluvastatin (n = 1050) or placebo (n = 1052) and followed for a mean time of 5.1 years. The end-points were major cardiac events. The average median time from transplantation to randomization was 4.5 years (range: 0.5-29 years). RESULTS: In patients starting treatment with fluvastatin <4.5 years after renal transplantation, the incidence of cardiac events was 4.6% over 5.1 years vs 9.2% in those on placebo (P = 0.007). Fluvastatin significantly reduced the risk of cardiac death and non-fatal myocardial infarction by 56% [risk ratio (RR): 0.44; 95% confidence interval (95% CI): 0.26-0.74; P = 0.002]. In a more detailed analysis patients were grouped into 2-year intervals (since the last transplantation). The frequency of cardiac death and non-fatal myocardial infarction was reduced by 3.2%, 5.1%, 9.6% and 8.2% with fluvastatin treatment as compared to 6%, 10.4%, 13.4% and 9.6% with placebo when treatment was initiated at 0-2, 2-4, 4-6 and >6 years, respectively. The risk reduction for patients initiating therapy with fluvastatin at years 0-2 (compared with >6 years) following transplantation was 59% (RR: 0.41; 95% CI: 0.18-0.92; P = 0.0328). This is also reflected in total time on renal replacement therapy: in patients in the first quartile (<47 months) fluvastatin use was associated with a risk reduction of 64% compared with 19% for patients in the fourth quartile (>120 months) (P = 0.033). CONCLUSIONS: Our data support an early introduction of fluvastatin therapy in a population of transplant recipients at high risk of premature coronary heart disease.

  • Cardiovascular risk and renal transplantation : post hoc analyses of the Assessment of Lescol in Renal Transplantation (ALERT) Study
  • 2005
  • Ingår i: American Journal of Kidney Diseases. - : Elsevier BV. - 0272-6386 .- 1523-6838. ; 46:3, s. 529-36
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Renal transplantation is associated with an increased risk for premature cardiovascular disease. We analyzed the data in the placebo arm of Assessment of Lescol in Renal Transplantation (ALERT) to improve our understanding of the relationship between cardiovascular risk factors and outcomes in this unique population. METHODS: We performed Cox survival analysis for myocardial infarction, cardiac death, and noncardiac death in 1,052 patients recruited to the placebo arm of ALERT. These subjects were aged 30 to 75 years, had stable graft function at least 6 months after transplantation, had a serum total cholesterol level between 155 and 348 mg/dL (4 and 9 mmol/L), and were receiving cyclosporine-based immunosuppression. RESULTS: The results confirm previous studies. In multivariate analysis, preexisting coronary heart disease (hazard ratio [HR], 3.69; P < 0.001), total cholesterol level (HR, 1.55 per 50 mg/dL; P = 0.0045), and prior acute rejection (HR, 2.36; P = 0.0023) were independent risk factors. Conversely, independent risk factors for cardiac death were age (HR, 1.58 per decade; P = 0.0033), diabetes (HR, 3.35; P = 0.0002), ST-T changes on the ECG (HR, 3.17; P = 0.0004), and serum creatinine level (HR, 2.65 per milligram per deciliter; P < 0.0001). CONCLUSION: This analysis confirms that renal transplant recipients share risk factors for myocardial infarction and cardiac death with the general population. However, the pattern of risk factors and their relationship with outcomes is atypical, highlighting the unique nature of cardiovascular risk in transplant recipients.
