Should I take statins for high cholesterol?
Introduction
This information will help you understand your choices, whether you share in the decision-making process or rely on your doctor's recommendation.
Key points in making your decision
Lowering your high cholesterol can help you prevent a heart attack or stroke. Consider the following when making your decision:
- High cholesterol is only one of several risk factors for heart disease. To reduce your risk of coronary artery disease (CAD) and heart attack, you need to reduce all of your risk factors, not just high cholesterol.
- If you have a high risk of heart attack, experts recommend immediate treatment with statins. The goal is to lower your LDL to 2.0 mmol/L or less as soon as possible.1 You have a very high risk if you have coronary artery disease and you also have diabetes, acute coronary syndrome, metabolic syndrome or if you smoke. It is important, however, that you discuss with your doctor whether statins are appropriate for you individually, based on your condition and medical history.
- The choice is less clear for people who have moderately high cholesterol and few risk factors for CAD and heart attack. This group may find this decision point most helpful.
- Therapeutic lifestyle changes are as important as medicine in reducing your risk for CAD and heart attack. For some people, quitting smoking, reducing blood pressure, losing weight, or getting more exercise can have the same or greater impact on reducing the risk of heart disease than taking medicine.
Medical Information
What is cholesterol, and why is high cholesterol dangerous?
Cholesterol is a type of fat. Your body needs it for many things, such as making new cells. But too much cholesterol in your blood increases your chances of heart attack and stroke.
What raises my chances of getting CAD and having a heart attack or stroke?
Your chances are higher if you:
- Are a man age 45 or older or a woman age 55 or older.
- Have a family history of CAD: CAD in your father or a brother younger than 55 or in your mother or a sister younger than 65.
- Have smoked any cigarettes within the past 30 days.
- Have high blood pressure (140/90 mm Hg or above) or are taking medicine for high blood pressure.
- Have a low HDL cholesterol level (below 0.9 mmol/L or 40 mg/dL).
- Have diabetes.
What are other risk factors?
Other factors that put you at risk for CAD and heart attack include high homocysteine levels, obesity and lack of regular exercise, menopause and the drop in estrogen that follows it, and metabolic syndrome.
Advisory. Health Canada advises that taking statins may increase the risk of developing muscle problems, including rhabdomyolysis, if you have certain other conditions. If you are considering taking a statin medicine or are already taking one, talk to your doctor.
