7. If you’ve had a heart attack, lowering your LDL (bad) cholesterol can increase your risk of having another heart attack. True or false?
Answers:
1. D. Your liver makes all the major blood fats. Excess amounts of LDL (bad) cholesterol are deposited in artery walls. In contrast, the job of HDL (good) cholesterol is to remove cholesterol from artery walls. Your total blood cholesterol and ratio of good to bad cholesterol can have a large impact on your risk for heart disease. Excess amounts of triglycerides may also increase heart risk.
2. B. Studies have shown that lowering LDL (bad) cholesterol can prevent heart attacks and reduce deaths from heart disease in both men and women. It can slow, stop or even reverse the buildup of plaque. It can also lower the cholesterol content in some plaques. This makes the plaques cause a heart attack.
3. False. Starting at age 20, men and women should have their cholesterol checked at least every five years. If your cholesterol level is high, you may need to have it checked more often. Talk to your doctor to find out what’s right for you.
4. A, C. Regular activity can help raise HDL (good) cholesterol and lower LDL (bad) cholesterol and triglycerides. It can also help you make improvements in two factors known to bump up cholesterol levels — obesity and increased abdominal girth. A waist of 40 or more inches in men, or 35 or more inches in women, needs to be trimmed.
5. True. The biggest sources of saturated fat are egg yolks, meat and full-fat dairy products such as milk, butter, cream and cheese. Trans fatty acids in hydrogenated vegetable oils can also increase your cholesterol levels.
6. B. You will continue to need exercise, weight control and a cholesterol-lowering diet even if you take medications.
7. False. Lowering LDL (bad) cholesterol levels reduces your risk of another heart attack.
