- 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.

- Gastrointestinal (GI) symptoms are common in renal transplant recipients and are associated with impaired health-related quality of life (HRQoL). We investigated clinician attitudes to GI symptoms and HRQoL in these patients by surveying 145 nephrologists from Sweden, Denmark, Finland, and Norway. In total, 79 clinicians responded. They estimated that 20% of their patients experienced GI discomfort and that 36% had impaired HRQoL. We previously conducted a survey of the renal transplant recipients treated-by-these clinicians, inwhich 92% reported troublesome GI symptoms and 53% had impaired HRQoL compared with the general population. Nephrologists were more likely to manage GI symptoms by reducing immunosuppressant dose (87%) than by switching medication to one with fewer GI side effects (66%). We conclude that clinicians appear to underestimate the prevalence of GI symptoms and impaired HRQoL. Improving patient-clinician communication could lead to more informed management, resulting in better HRQoL and increased graft survival.

- Background. Immunosuppressive therapies have been associated with gastrointestinal (GI) side effects, which may impair health-related quality of life (HRQoL). Methods. In this survey, 4,232 renal transplant recipients from Denmark, Finland, Nor-way, and Sweden completed the Short-Form 36 (SF-36) questionnaire and the Gastrointestinal Symptom Rating Scale (GSRS). SF-36 scores were compared with country norm values. Multiple logistic regression analysis was used to identify immunosuppressants associated with GI symptoms. Results. The prevalence of troublesome GI symptoms (GSRS > 1) was 83% for indigestion, 69% for abdominal pain, 58% for constipation, 53% for diarrhea, 47% for reflux, and 92% for any GI symptom. Compared with the general population, HRQoL was most commonly meaningfully impaired in the general health dimension (53% of patients). The presence and severity of GI symptoms were associated with worse HRQoL. Tacrolimus showed a significant association with diarrhea (odds ratio [OR]: 1.7; 95% confidence interval [CI]: 1.4-2.0) and constipation (OR: 1.3; 95% Cl: 1.1-1.6), and sirolimus with indigestion (OR: 2.9; 95% Cl: 1.0-8.1) and abdominal pain (OR: 2.2; 95% Cl: 1.1-4.4). Conclusions. GI symptoms are associated with impaired HRQoL in the renal transplant population. Managing GI symptoms by careful choice of immunosuppressants should be a focus for improving HRQoL in renal transplant recipients

- OBJECTIVES: Atherosclerosis is common in patients with chronic kidney disease (CKD), and cardiovascular disease (CVD) represents a major cause of death. The National Kidney Foundation guidelines favour the use of statin therapy for treatment of dyslipidaemia in patients with CKD. Much evidence supports statin therapy for reducing CVD and improving outcomes in the general population, but there is less evidence in patients with CKD. Consequently, prevention of CVD in CKD is based primarily on extrapolation from non-CKD trials. Significantly, in trials specifically designed to investigate patients with CKD, evidence is emerging for improved cardiovascular outcomes with statin therapy. This review describes available data relating to cardiovascular outcomes and the role of statins in patients with CKD, including pre-dialysis, dialysis, and renal transplant patients. RESEARCH DESIGN AND METHODS: The PubMed database was searched (1998-present) to ensure comprehensive identification of publications (including randomised clinical trials) relevant to CKD patients, patterns of cardiovascular outcome in such patients and their relationship to lipid profile, and the role of statins for the prevention and treatment of cardiovascular complications. RESULTS: There are conflicting data on the relationship between dyslipidaemia and cardiovascular outcomes, with one major study of statin therapy (4D--Deutsche Diabetes Dialyse Studie) providing equivocal results. Further studies, including AURORA (A study to evaluate the Use of Rosuvastatin in subjects On Regular haemodialysis: an Assessment of survival and cardiovascular events; NCT00240331) in patients receiving haemodialysis, and SHARP (Study of Heart And Renal Protection; NCT00125593) in patients with CKD including those on dialysis, should help to clarify the role of statin therapy in these populations. CONCLUSIONS: More studies are needed to elucidate the role of statins in improving cardiovascular outcomes for CKD patients. It is anticipated that ongoing clinical trials geared towards the optimal prevention and treatment of CVD in patients with CKD will help guide clinicians in the management of CKD.

Recension (övrigt vetenskapligt/konstnärligt)abstract
- 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.

- Background: Cardiovascular disease (CVD) is the leading cause of death in patients with end-stage renal disease (ESRD). Aims: AURORA (A study to evaluate the Use of Rosuvastatin in subjects On Regular haemodialysis: an Assessment of survival and cardiovascular events) is the first large-scale international trial to assess the effects of statins on cardiovascular outcomes in patients with ESRD on chronic haemodialysis. Preliminary baseline data from the randomised population are presented. Methods: A total of 2,775 patients from 280 centres in 25 countries were randomised into the study. Patients aged 50-80 years on regular chronic haemodialysis for at least 3 months before screening were eligible for inclusion. They were randomised 1:1 to receive either rosuvastatin 10 mg or placebo daily and assessed throughout the study. Results: The mean age at baseline was 64 years. Most patients were male (62%) and 85% were white. The median time since commencing renal replacement was 32 months. Mean total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels were 4.53 mmol/l (175 mg/dl) and 2.57 mmol/l (99 mg/dl), respectively. Conclusion: Results from the AURORA trial will impact on the current guidelines and use of statins in this patient population.

- 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.

- Background: Concerns have recently been raised regarding a potential harmful effect of statins on renal function. This study investigated the effect of fluvastatin treatment on renal function in renal transplant recipients enrolled in the Assessment of Lescol in Renal Transplantation (ALERT) trial. Methods: ALERT was a randomized, double-blind, placebo-controlled study of the effect of fluvastatin, 40-80 mg daily (n = 1050) or placebo (n = 1052) on cardiac and renal outcomes in renal transplant recipients over a follow-up period of five to six years. The incidence of graft loss, changes in serum creatinine, calculated creatinine clearance and proteinuria, and the incidence of renal adverse events (AEs) were assessed in both treatment groups. Results: Fluvastatin treatment in ALERT had no significant effect compared with placebo on renal function, assessed by serum creatinine (overall adjusted mean +/- SEM: fluvastatin, 175.4 +/- 2.20 mu mol/L; placebo, 172.7 +/- 2.20 mu mol/L; p = 0.39), creatinine clearance (fluvastatin, 55.3 +/- 0.30 mL/min; placebo, 55.8 +/- 0.30 mL/min; p = 0.26) or proteinuria (fluvastatin, 0.58 +/- 0.03 g/24 h; placebo, 0.53 +/- 0.03 g/24 h; p = 0.31). There were no significant differences between treatment groups when the 283 patients suffering graft loss were excluded from the analysis. Fluvastatin also had no detrimental effect on creatinine clearance or proteinuria in the subgroup of 340 diabetic patients without graft loss in ALERT. No notable differences in the rate of renal or musculoskeletal AEs were observed between fluvastatin and placebo groups. Conclusions: Fluvastatin had no detrimental effect on renal function, or the risk of renal AEs, in renal transplant recipients with or without diabetes enrolled in ALERT. Fluvastatin treatment for the prevention of cardiac events may therefore be used without fear of jeopardizing renal function.

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 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.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Statins reduce the incidence of cardiovascular events in patients at high cardiovascular risk. However, a benefit of statins in such patients who are undergoing hemodialysis has not been proved. METHODS: We conducted an international, multicenter, randomized, double-blind, prospective trial involving 2776 patients, 50 to 80 years of age, who were undergoing maintenance hemodialysis. We randomly assigned patients to receive rosuvastatin, 10 mg daily, or placebo. The combined primary end point was death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke. Secondary end points included death from all causes and individual cardiac and vascular events. RESULTS: After 3 months, the mean reduction in low-density lipoprotein (LDL) cholesterol levels was 43% in patients receiving rosuvastatin, from a mean baseline level of 100 mg per deciliter (2.6 mmol per liter). During a median follow-up period of 3.8 years, 396 patients in the rosuvastatin group and 408 patients in the placebo group reached the primary end point (9.2 and 9.5 events per 100 patient-years, respectively; hazard ratio for the combined end point in the rosuvastatin group vs. the placebo group, 0.96; 95% confidence interval [CI], 0.84 to 1.11; P=0.59). Rosuvastatin had no effect on individual components of the primary end point. There was also no significant effect on all-cause mortality (13.5 vs. 14.0 events per 100 patient-years; hazard ratio, 0.96; 95% CI, 0.86 to 1.07; P=0.51). CONCLUSIONS: In patients undergoing hemodialysis, the initiation of treatment with rosuvastatin lowered the LDL cholesterol level but had no significant effect on the composite primary end point of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke.

- 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.

- 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.

- OBJECTIVE: Patients with systemic lupus erythematosus (SLE), with or without end-stage renal failure, are at increased risk of premature cardiovascular disease. Although statin therapy has been found to reduce cardiovascular risk in the general population, its effectiveness in kidney transplant recipients with SLE has not been examined. This study was undertaken to investigate the effect of fluvastatin on cardiac end points in a randomized controlled trial of renal transplant patients with SLE. METHODS: Patients with SLE were identified from among participants in the Assessment of Lescol in Renal Transplantation trial, a randomized, double-blind, placebo-controlled study of the effect of fluvastatin (40-80 mg/day) on cardiovascular outcomes in renal transplant recipients. Patients were randomized to either a group receiving fluvastatin or a placebo group for the duration of the 5-6-year trial, and then invited to continue in a 2-year open-label extension during which all participants, regardless of original group, received fluvastatin. Patients were followed up for a total of 7-8 years for assessment of the primary end point of major cardiac events, comprising nonfatal myocardial infarction, cardiac death, and coronary intervention procedures. RESULTS: Fluvastatin reduced low-density lipoprotein cholesterol levels by 29.2% (95% confidence interval [95% CI] 18.3-40%), from a mean +/- SD of 4.0 +/- 0.9 mmoles/liter to 2.8 +/- 1.1 mmoles/liter, and total cholesterol by 19.6% (95% CI 11.7-27.5%), from 6.4 +/- 0.9 mmoles/liter to 5.1 +/- 1.1 mmoles/liter. Compared with placebo-treated patients, patients randomized to receive fluvastatin exhibited a 73.4% reduction in the risk of major cardiac events (relative risk 26.6 [95% CI 5.9-119.4], P = 0.064). CONCLUSION: Our results indicate that the effect of fluvastatin on cardiac events in renal transplant recipients with SLE is similar to that observed with statin therapy in the renal transplant population as a whole.

- BACKGROUND: Female gender offers a cardioprotective effect over men in the general population, but is lost in the dialysis population. Whether renal transplantation restores the gender-dependent cardiac protection and whether there is a difference in the impact of risk factors is not known. METHODS: This is a post hoc analysis of pre-defined end points in the placebo arm in the Assessment of Lescol in Renal Transplantation (ALERT) study, a study in renal transplant recipients. Cox regression was performed to estimate the association between different risk factors at baseline and non-fatal myocardial infarction (MI) or cardiac death and total mortality, and specifically assess whether there are gender differences. RESULTS: The placebo arm included 1052 patients (mean age 50.1 +/- 11.1 yr, 65.3% males) with a mean follow-up of 65 months. The incidence of non-fatal MI or cardiac death was 10.9% vs. 7.9% (NS) and total mortality 13.3% vs. 12.8% (NS) in men and women. In multivariate analysis, previous coronary heart disease (CHD), diabetes, treatment for rejection and serum triglycerides were predictive for cardiac events in men, and low-density lipoprotein (LDL)/high-density lipoprotein (HDL) ratio only in women. A slightly different risk-factor pattern appeared for total mortality. Diabetes, ECG abnormalities, plasma triglycerides, serum creatinine, time on dialysis and age predicted total mortality in men, while ECG abnormalities, LDL/HDL ratio and age were predictors in women. CONCLUSION: In this relatively low-risk population of renal transplant recipients, no gender difference in cardiac events or total mortality was observed, suggesting that female gender advantage regarding CHD is not restored following transplantation. The predictive value of risk factors differed in men and women.

- The Assessment of Lescol in Renal Transplantation clinical trial demonstrated the efficacy of fluvastatin in reducing cardiovascular (CV) disease in renal transplant recipients. The study included a voluntary pharmacogenetic component, enrolling 1,404 patients, which allowed association testing of baseline measures and longitudinal analysis of the 707 fluvastatin-treated and 697 placebo-treated individuals. A candidate gene approach, examining 42 polymorphisms in 18 genes, was used to test for association between selected polymorphisms and major adverse cardiac events, graft failure, change in LDL and HDL cholesterol, and baseline LDL and HDL cholesterol. Reported associations between cholesteryl ester transfer protein (CETP) and baseline HDL cholesterol were replicated, with four previously implicated single nucleotide polymorphisms significantly associated in males and one in females; tests of reported associations between CETP and CV disease yielded varying results. We found no evidence for genetic factors affecting fluvastatin response. Polymorphisms in 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) previously reported to affect the efficacy of pravastatin did not show a similar effect on the reduction of LDL cholesterol by fluvastatin.

- Background: Renal transplant recipients (RTR) have high risk for cardiovascular disease (CVD). They also have high prevalence of insulin resistance and metabolic syndrome (MS). Statin treatment reduces CVD risk in RTR. The aim was to study MS as CVD risk factor in RTR, and to investigate the effect of statin treatment in RTR with MS. Methods: In total, 1706 non-diabetic RTR from the Assessment of Lescol in Renal Transplantation trial were followed for 7-8 yr. The captured endpoints included major adverse cardiac events [MACE, defined as cardiac death (CD), non-fatal myocardial infarction or coronary revascularization procedure], and CD. MS was defined at baseline according to Adult Treatment Panel III definition with waist girth replaced by body mass index >/=30 kg/m(2). Results: MS was diagnosed in 32% of the patients. During the follow-up, MACE incidence was 16% in those with MS and 11% in those without MS (p < 0.001). Statin treatment reduced MACE risk by 53% in the group with MS. CD risk was 74% higher in RTR with MS (p = 0.012), and statin treatment reduced CD risk in those with MS (p = 0.03). Conclusions: RTR with MS have increased risk for CVD. RTR with MS are an easily identifiable group of patients who benefit from statin treatment.

- Background. Renal transplant recipients (RTR) mainly die of premature cardiovascular disease. Traditional cardiovascular disease risk factors are prevalent in RTR. Additionally, non-traditional risk factors seem to contribute to the high risk. The impact of renal dysfunction was compared with traditional risk factors for cardiovascular morbidity and mortality in 1052 placebo-treated patients of the ALERT trial.Methods. All patients were on cyclosporine-based immunosuppressive therapy, follow-up was 5-6 years and captured endpoints included cardiac death, non-cardiovascular death, all-cause mortality, major adverse cardiac event (MACE), non-fatal myocardial infarction (MI) and stroke.Results. A calculated 84 mu mol/l increase in serum creatinine was needed to double the risk for cardiac death, an increase of 104 mu mol/l to double the risk for non-cardiovascular death and an increase of 92 mu mol/l to double the risk for all-cause mortality. MACE risk was doubled if serum creatinine was elevated by 141 mu mol/l, age was increased by 23 years, or LDL-cholesterol by 2 mmol/l. Diabetes increased the incidences of cardiac death, all-cause mortality, MACE, stroke and non-fatal MI. A serum creatinine increase of similar to 130 mu mol/l, or similar to 20 years increase in age was calculated as similar in risk for cardiac death, all-cause mortality and MACE, and comparable to risk of diabetes in RTR.Conclusion. An increase in serum creatinine of 80-100 mu mol/l doubles the risk for cardiac death, non-cardiovascular death and all-cause mortality in RTR. An increase of 130 mu mol/l in serum creatinine or similar to 20 years increase in age is comparable to risk of diabetes.
