Whats new - CVD Risk assessment
  • Combines advice on BP, lipids CVD risk in
    diabetes and some angina, MI, TIA and stroke
  • All treatment decisions based on absolute
    cardiovascular risk
  • Shows that assessment and treatment of CVD risk
    above 15 is cost effective
  • Fasting bloods recommended

7
What is different
8
Who to risk assess
9
High risk groups for CVD/diabetes
  • Family history of premature CVD or diabetes
  • Personal history of gestational diabetes or
    polycystic ovary syndrome
  • Current smoking
  • Prior BP gt 160/95 or TCHDL ratio gt 7
  • IGT or IFG
  • Obesity (BMI gt 30)
  • Truncal obesity Waist Circ gt 100cm men
  • or gt 90cm women

10
Select people for risk assessment
Reduce 5 year CVD risk to lt15

11
What to measure
  • Age and sex
  • Ethnicity
  • Smoking history
  • Family history
  • Fasting lipid profile and fasting glucose
  • Average of two sitting BP
  • BMI and waist circumference

Adjust risk
  • 5 can be added for people with
  • Family history of premature CHD
  • Maori or Pacific or from the Indian sub continent
  • Diabetes and microalbuminuria
  • Diabetes for gt 10 years or HbA1c gt 8
  • Metabolic syndrome

Adjusted CVD Risk
Clinical CVD or High risk diabetes Some
genetic lipid disorders
Consider specialist referral
Drug interventions
Treatment Intensity
Urgent intense multifactor treatment
Drug intervention directed at all risk factors
Lifestyle interventions

General advice
Intensive individual advice
Specific advice
CVD Risk goal
Reduce risk
Reduce 5-year CVD risk to lt 15
19
NNT for 5 years to prevent one CVD event

Treatments (gt20)
  • Simultaneous drug treatment of all modifiable
    risk factors
  • Aspirin (low dose)
  • BP lowering (two drugs often needed)
  • Lipid modification (statin usually)
  • (Glycaemic control if diabetes)

21
Goals
  • Overall goal is to reduce risk 5 year
    cardiovascular risk to lt15

22
Lipid Targets

BP Targets
24
Who should get an OGTT after the Fasting Plasma
Glucose
non-european, family history diabetes, PMH of
gestational diabetes or the metabolic syndrome
25
Follow up
  • Cardiovascular risk assessments at least annually
  • Risk factor monitoring 3 to 6 monthly
  • ALT at baseline and once thereafter
  • CK only if symptomatic with muscle aches
  • Reduce dose 3-10 x normal
  • Stop at 10 X normal

26
Summary
  • Major reductions in CV risk are possible
  • GPs and practice nurses are ideally placed to
    detect CV risk, advise and promote lifestyle
    change. Discussing the benefits of drug therapy
    where indicated.
  • These guidelines encourage us to think of
    Diabetes and CVD together

27
Whats new - Diabetes
  • Optimums
  • BP control lt 130/80
  • TC lt 4 mmol/L
  • Triglycerides lt 1.7 mmol/L
  • HbA1c as close to physiological as possible
    (preferably lt7)
  • ACE-inhibitor or A2 receptor-blocker for
    microalbuminuria and overt nephropathy

28
Whats new Diabetes 2
  • Screening for microalbuminuria
  • ACR gt 2.5 mg/mmol in men
  • ACR gt 3.5 mg/mmol in women
  • Overt nephropathy
  • ACR gt30mg/mmol

29
Whats new Medication after MI or stroke
  • Aspirin 75mg -150 mg routinely
  • as soon as possible after stroke (CT scan prior
    to starting)
  • Beta-blockers for all (including those with LV
    dysfunction and stable heart failure
  • ACE-inhibitors for all
  • Statins (20-40 mg simvastatin) see next slide,
    dose dependent on lipid profile

30
Average daily doses
  • Reproduced with permission from Professor Russell
    Scott.
  • Note At the time of publication Rosuvastatin was
    not currently subsidised in New Zealand

31
Whats new AF
  • AF is common 10 of gt80 yr old
  • Majority will require anticoagulation
  • Rate control and TE prophylaxis is best treatment
    for most people
  • Echocardiography is NB part of assessment
  • Sotalol should not be used for rate control

32
Implementation
  • Desktop resource
  • Electronic decision support
  • Consumer resource
  • Train the trainer and teaching resources
  • Case study (BPACnz)
  • NZ Doctor how to treat article
  • PHARMAC campaign
  • Consortium formed (NHF / Stroke foundation /
    Diabetes NZ / NZGG) to promote pilot projects
