1
Prevalence and management of cardiovascular risks in renal transplant recipients Dr VS Aithal Consultant Nephrologist Swansea
2
Transplantation improves survival when compared with dialysis Survival remains well below general population 50% die with a functioning transplant and 50% of these from cardiovascular causes Annual rate of fatal/nonfatal CVD events 3.5- 5% in transplant recipients
3
Cardiovascular risk factors Smoking HTN Hyperlipidaemia (low HDL included) Family history of CV disease Age (men >45,women >55y) Diabetes
4
Cardiovascular risk factors BMI>30 Physical inactivity Ethnicity Immunosuppressives Graft dysfunction/failure Anaemia Rejection episodes Proteinuria
5
Renal transplants older than 1yr as of July 2015 were included in the audit Patients less than 18yrs of age were excluded from the analysis CardiffSwanseaWrexhamBangorGC Patients93330813774
6
Age 20-30% of patients 60-70yrs. 10-15% of patients >70yrs
8
Audit standards for cholesterol Annual check (2C) Treatment targets should be the same as in general population (2C) ALERT study: after a 5yr FU, LDL reduced by 32% in fluvastatin arm. Risk of cardiac death of non-fatal MI was reduced by 35%
9
Cholesterol <5
10
Statin and Aspirin
11
Cholesterol >5
12
Creatinine 6-20% had Cr 200-300. 2-4 % had Cr 300-400
13
Haemoglobin <10g 3-8% <9G 1-5%
14
BMI
15
5mmHg reduction in BP reduces risk of MI by 10-15% Modest reduction of BP with treatment of hyperlipidaemia in high risk patients with transplants improved patient survival by 2yrs
16
Hypertension RA/KDIGO guidline: 50 (2C) BP should be recorded at every visit (1C)
17
Systolic BP 3-13.5% have systolic HTN 1-3% have severe systolic HTN
18
Diastolic BP
19
Aspirin Metanalysis of 287 studies (135000pts) absolute reductions in serious vascular event in patients with previous MI was 36/1000 treated pts and 22/1000 treated high risk patients (stable angina,PVD)
20
Statin and Aspirin
21
ACE-I/ARB
22
Antihypertensives
23
Not on antihypertensives
24
Diabetes Check blood glucose every visit (2C) Annual HbA1c HbA1c 7-7.5(53-58)
26
HbA1c in target range
27
HbA1c >60
29
HbA1c Swansea 15/60 43.2% had HbA1c >60
30
Wrexham HbA1c 48.25% had HbA1c >60
31
30% had HbA1c >60
32
GC HbA1c 50% had HbA1c >60
33
HbA1c Cardiff 326 patients had HbA1c in the last 12months
34
Conclusions 30-45% had cholesterol >5, 6-12% had 6-8 (except Wrexham) 30 to 50% had HbA1c >60 20-30% of our patients are obese 3-8% of our transplant patients had Hb<10, 1-5% had Hb<9
35
Conclusions 30-45% did not meet BP standards for systolic and 4-14% had systolic BP>160 35-59% did not meet standards for diastolic BP and 5-17% had diastolic >90
36
Data for next audit Smoking history Family history of CV events Proteinuria Patients on prednisolone
37
Data for next audit Need to audit data on random glucose from every visit and see if there are undiagnosed diabetics Need data on proteinuria. ? Document proteinuria from every visit and check if PCR requested in all pts with proteinuria. Alternatively check urine PCR/ACR at regular intervals Data on use of ACE-I in those with proteinuria
38
Acknowledgements Dr Donovan, Dr Griffin, Gary Hunter Cardiff Dr Judith Welham Wrexham Dr Abdul Alejmi Bangor Dr Aled Lewis GC Mike Wakelyn and Cathy Blakemore Swansea
39
50 patients from swansea had urine PCR,26 pts had PCR >50. 12/26 were on ACE-I 27 patients from Wrexham had urine PCR checked. 12 had PCR>50. 9/12 were on ACE-I

5mmHg reduction in BP reduces risk of MI by 10-15% Modest reduction of BP with treatment of hyperlipidaemia in high risk patients with transplants improved patient survival by 2yrs (55)
