IAL Edexcel Biology - Cardiovascular Disease (3): Dietary Antioxidants, Cholesterol and Treatments
Topic 1 Molecules Transport and Health
1.13 Understand the link between dietary antioxidants and the risk of cardiovascular
1.18(i) Be able to analyse data on the possible significance for health of bloodcholesterol levels and levels of high-density lipoproteins (HDLs) and low-density lipoproteins (LDLs)
1.18(ii) Know the evidence for a causal relationship between blood cholesterol levels(total cholesterol and LDL cholesterol) and cardiovascular disease (CVD)
1.19 Understand how people use scientific knowledge about the effect of diet, including obesity indicators, such as body mass index and waist-to-hip ratio, exercise and smoking to reduce their risk of coronary heart disease
1.20 Know the benefits and risks of treatments for cardiovascular disease (CVD) (antihypertensives, statins, anticoagulants and platelet inhibitors)
Vitamin C - a dietary antioxidant
Low density lipoprotein (LDL); “bad” cholesterol
"Good" and "bad" cholesterol have the same chemical structure but differ only in the way it is being carried in blood.
Cholesterol and CVD
👇 Study the mechanism and side effects of each treatment for your IAL Edexcel Biology 👇
Medical treatments for CVD
Diuretics (an antihypertensive)
Beta blockers (an antihypertensive)
ACE inhibitors (an antihypertensive)
Anticoagulants (e.g. warfarin)
Platelet inhibitory drugs (e.g. aspirin, clopidogrel)
