چکیده

BACKGROUND Cardiovascular disease is the leading cause of mortality among renal transplant recipients. In the general population, coronary artery calcification (CAC) and progression of CAC are predictors of future cardiac risk. We conducted a study to determine the progression of CAC in renal transplant recipients; we also examined the factors associated with progression and the impact of the analytic methods used to determine CAC progression. METHODS We used multi-detector computed tomography to examine CAC in 150 prevalent renal transplant recipients, who did not have a documented cardiovascular disease. A baseline and a follow-up scan were performed and changes in CAC scores were evaluated in each patient individually, to calculate the incidence of CAC progression. Multivariate logistic regression analysis was used to evaluate the determinants of CAC progression. RESULTS Baseline CAC prevalence was 35.3% and the mean CAC score was 60.0 ± 174.8. At follow-up scan that was performed after an average of 2.8 ± 0.4 years, CAC prevalence increased to 64.6% and the mean CAC score to 94.9 ± 245.7. Progression of individual CAC score was found between 28.0 and 38.0%, depending on the method used to define progression. In patients with baseline CAC, median annualized rate of CAC progression was 11.1. Baseline CAC, high triglyceride and bisphosphonate use were the independent determinants of CAC progression. CONCLUSIONS Renal transplantation does not stop or reverse CAC. Progression of CAC is the usual evolution pattern of CAC in renal transplant recipients. Beside baseline CAC, high triglyceride level and bisphosphonate use were associated with progression of CAC.

Coronary artery calcification in renal transplant recipients.

Cardiovascular disease is the leading cause of mortality in renal transplant recipients. Although renal transplant recipients frequently undergo cardiac functional tests prior to surgery, coronary atherosclerosis can remain undetected. Coronary artery calcification (CAC), an early marker of atherosclerosis can be quantified using EBCT. The purpose of this study was to determine the extent and c...

Coronary artery calcification and coronary ischaemia in renal transplant recipients.

BACKGROUND Cardiovascular disease is the leading cause of mortality among renal transplant recipients. Data on the relationship between coronary artery calcification (CAC) and coronary ischaemia in renal transplantation patients are scant. We conducted a study to determine the prevalence and determinants of CAC in these patients; we also examined the frequency of coronary ischaemia in patients ...

Aortic calcification predicts cardiovascular events and all-cause mortality in renal transplantation.

BACKGROUND Cardiovascular disease is a leading cause of death among renal transplant recipients. Aortic calcification is associated with increased mortality in dialysis subjects. The significance of aortic calcification among renal transplant recipients is unknown. Our objective was to prospectively examine the association of aortic calcification with cardiovascular events and all-cause mortali...

Serum Bone Markers and Coronary Artery Calcification in End Stage Renal Failure Patients and Kidney Transplant Recipients

Background: Variety of growth factors and cytokines are involved in the process of bone turnover. Evidences are showing that alterations in OPG/RANK/RANKL system form the basis of many metabolic diseases. So, we evaluated the relationship between OPG and RANKL levels, to establish a possible relationship with other bone markers and coronary artery calcification. Methods: Patients with chronic k...

Cardiovascular Risk factors Analysis in Renal Transplant Recipients

Renal transplantation is currently the preferred treatment modality for virtually all suitable candidates with end-stage renal disease. When compared with the general population, cardiovascular mortality in transplant recipients is increased by nearly 10-fold among patients within the age range of 35 and 44 and at least doubled among those between the ages of 55 and 64. All transplant recipient...
