Q

Epidemiology of heart disease in Canada?

A

Mortality rates from CVD has gone down since 1960. Then, 2/3 of people died within a year after heart attack. Today, the one year mortality is only about 5%, if you are under 70. However, the burden of disease is increasing.

Q

What is exposure? What is susceptibility?

A

Exposure - reactive oxygen species that can cause damage in the arteries Susceptibility - how likely you are to get a disease based on genetics CVD = Exposure + Susceptibility

Q

Glagov’s Model?

A

The disease starts not in the donut hole of the artery, but in the walls of the donut. The plaques in the donut walls can rupture, andform a blood clot which occludes blood flow.

Overabundance

17
Q

What are the 3 emerging risk factors for vascular disease?

A

Sedentary behaviour

Obesity

Trans-fats

18
Q

What are the 3 predictors of susceptibility to heart disease?

A

Age (older puts you at risk)

Gender (men earlier than women)

Genetics

19
Q

Why do we get calcification of the arteries?

A

Calcium is deposited in response to chronic inflammation, and in the coronary arteries, plaque accumulation causes this.
