Assessment of Cardiovascular Risk Factors after Renal Transplantation: A Step towards Reducing Graft Failure

BackgroundProlongation of renal allograft survival a considerable challenge. The primary cause of renal graft failure is recipient death and cardiovascular disease is the leading cause of mortality. We assessed the management of hypertension, dyslipidemia and diabetes mellitus (DM) in a protocol-driven renal transplant clinic.MethodsWe reviewed 128 patients who received a renal allograft between 2004 and 2008 at our institution. Blood pressure (BP), low density lipoprotein (LDL) and hemoglobin AlC (HbAlC) were assessed annually for up to 5 years. Results were compared with the Kidney Disease: Improving Global Outcomes guidelines which target BP at ≤ 130/80 mmHg, LDL ≤ 100 mg/dL, and HbAlC ≤ 7.5%. Use of statins and antihypertensive medications was reviewed. Chi-square and t tests were used for analysis.ResultsA history of hypertension, dyslipidemia, and DM were present in 96.1%, 60.9%, and 43.8%, respectively. The percentage of patients on ≥3 antihypertensive medications, statins, and other lipid-lowering medications were 38.01%, 44.5%, and 17.2%, respectively. One-year posttransplant targets for BP, LDL, and HbAlC were achieved in 41.4%, 71.7%, and 70.5% of patients, respectively. Five-year posttransplant target BP, LDL, and HbAlC were achieved in 55%, 91.7%, and 88.9% of patients, respectively.ConclusionsEven in a university-based clinic with protocols designed to improve compliance, treatment goals for BP, LDL, and HbAlC were not achieved in a substantial number of patients, especially in the first year posttransplantation. Better strategies are needed to meet treatment objectives and prevent untoward outcomes.
