Cardiometabolic risk

12 important questions on Cardiometabolic risk

What are the 5 stages in the process of Cardiometabolic disease

  1. Healthy
    1. able to adapt
  2. Early changes
    1. small abnormalities; do not yet affect the functioning of the body
  3. Preclinical phase
    1. elevated risk factors; insulin resistance, low-grade inflammation and changes to arterial wall, high blood pressure and cholesterol, loss of kidney function
  4. Screening
    1. e.g. Oral glucose tolerance test or heart scan can for calcification in coronary arteries
  5. clinical phase
    1. disease event; with hospitalisations and specialist care

You can have exogenous risk factors and endogenous risk factors for Cardiometabolic diseases. Name a few

Exogenous factors: (modifiable risk factors)
  • smoking
  • diet
  • physical activity
  • alcohol use
  • stress
  • other lifestyle and environmental factors

Endogenous factors (biological/intrinsic factors): (non-modifiable risk factors)
  • age
  • sex
  • genetic factors
  • blood lipids
  • blood pressure
  • body composition
  • diabetes mellitus
  • chronic inflammation


CV risk factors not only affect heart and blood vessel, but also kidney, brain and eye

What are the 'new' pathways in Cardiometabolic disease?

Which CVD risk factor is the largest contributor to morality worldwide?

Raised blood pressure

Blood pressure and risk of IHD and stroke. How does this looks like in a graph. And when do you reach the hypertension gut of point

Risk increases already at SBP > 115 mmHg!

What are the cholesterol target values?

Total cholesterol (TC)
  • <5 mmol/l normaal
  • >5 mmol/l slightly elevated
  • >6,5 mmol/l elevated
  • >8.0 mmol/l highly elevated

HDL
  • >1.5 is healthy

Triglycerides
  • <1.7 is healthy

Cholesterol Ratio (TC/HDL)
  • <4 is healthy

LDL
  • <3 is healthy

What is the influence of total blood cholesterol on CHD mortality and stroke mortality

Cholesterol is a strong risk factor for CHD mortality, but not for stoke mortality

Three important pathways for CMD

  1. Saturated fat intake
  2. Raised serum (LDL) cholesterol
  3. Atherosclerosis
  4. Myocardial infarction (CHD)


  1. High salt intake
  2. Raised blood pressure
  3. Kidney function decline & stroke


  1. Low fibre intake
  2. Obesity
  3. Type 2 diabetes & CHD

Rothman's pie model for causality

The three patients had their heart attack for different reasons

A risk factor that all three have in common might be a necessary cause, that always needs to be present before the disease can develop

N.B. A necessary cause does not have to be a sufficient cause!

Who does the SCORE system works?

SCORE: systematic coronary risk evaluation

based on gender, age, total cholesterol, systolic blood pressure and smoking status

based on individual's risk to die from CVD within next 10 year

In the USA they have the Framingham risk score

Algorithm to predict the 10-years risk of developing CHD of an individual, developed with data from the Framingham heart study

How does the prevention of the guidelines European society of cardiology look like?

If 10-years risk >5%
  • Quit smoking
  • Physical activity >= 5x per week (30 min)
  • alcohol: max. 2 glasses (women) or 3 glasses (men) per day (Dutch health council: 0-1 glasses per day
  • Optional body weight (BMI < 25kg/m2)
  • dietary advice
    • <10% saturated fat, <1% trans fat
    • fish: 1-2 times per week
    • 200 grams vegetables and 2 pieces of fruit
    • salt: max. 6 grams per day

If 10-years risk >10%
  • all of the above PLUS
  • statins and antihypertensive medication
