High Cholesterol? 7 Things That Determine Whether You Need a Statin
September 01, 2026
Finding out that you have high cholesterol can leave you with one big question: Do I need a statin?
But the answer isn’t just based on your cholesterol results alone.
Your doctor will also look at your age, family history, other health conditions and even whether plaque has already started building up in your arteries.
“Two people with the same cholesterol level may not have the same risk for heart disease,” says Chad Conner, MD, with Hartford HealthCare’s Heart and Vascular Institute. “The decision to recommend a statin should be based on the full picture.”
For some people, those additional risk factors make starting a statin more important. For others, it makes sense to gather more information first.
So before you focus on one cholesterol number, here are seven things your doctor may consider.
1. Your LDL cholesterol level
LDL is often called “bad” cholesterol because high levels can contribute to plaque buildup inside your arteries.
But there isn’t one ideal LDL level for everyone.
Your personal goal may depend on whether you already have heart disease or other conditions that increase your risk. Someone who has had a heart attack, for example, may need a lower LDL level than someone with no history of cardiovascular disease.
“Your LDL level gives us an important starting point,” says Dr. Conner. “But we also need to understand what that number means for you.”
Current statin guidelines encourage your doctor to set an LDL goal based on your personal risk, rather than treating every patient the same way.
Ask your doctor what your LDL level is and what range you should aim for.

2. Your future risk for heart disease
Your cholesterol level tells your doctor what’s happening now. A risk calculator can help show what could happen over time.
Your doctor may use a tool called PREVENT to estimate your risk for cardiovascular disease.
For eligible adults ages 30 to 79, it can estimate risk over the next 10 years and the next 30 years.
That longer view may be especially helpful for younger adults. A younger person may have a low chance of experiencing a heart attack soon but still have risk factors that could cause problems after years of cholesterol buildup.
“Younger adults often have a low short-term risk because of their age,” says Dr. Conner. “Looking farther ahead can help us decide whether it makes sense to act before that risk increases.”
Your doctor can walk you through your results and explain whether they support starting medication.

3. Your family history
Heart disease in your family may affect when your doctor recommends treatment.
Before your next appointment, try to find out whether a parent, sibling or other close relative has had a heart attack, stroke or another form of cardiovascular disease.
The age at which it happened also matters. Heart disease that develops earlier than expected may point to an inherited risk.
“A family history of early heart disease can change how we view someone’s cholesterol results,” says Dr. Conner. “It may be a reason to look more closely at their risk or consider treatment sooner.”
Share any details you know with your doctor, including the condition your relative had and how old they were at the time.

4. Your other health conditions
Cholesterol is only one part of your heart health.
Diabetes, high blood pressure and chronic kidney disease can all raise your risk for cardiovascular disease. Other factors, like your smoking history and certain inflammatory conditions also affect whether a statin is recommended.
Even if each concern seems manageable on its own, the combination can make a difference.
“Health conditions can build on one another,” says Dr. Conner. “That’s why a cholesterol result needs to be considered alongside the rest of your medical history.”
Make sure your doctor knows about any conditions being treated by another provider, as well as any history of smoking.
5. Your Lp(a) level
You may be familiar with LDL, HDL and triglycerides.
But there’s another number that isn’t usually included in a standard cholesterol test: lipoprotein(a), or Lp(a).
Your Lp(a) level is largely determined by genetics. It can be high even if you eat well, exercise regularly and have no other obvious risk factors for heart disease.
Current guidelines recommend that every adult have an Lp(a) test at least once. Since the level tends to remain stable, most people won’t need regular repeat testing.
“Lp(a) can uncover inherited risk that might otherwise be missed,” says Dr. Conner. “A high result doesn’t automatically mean you need a statin, but it may affect how closely we manage your other risk factors.”
Ask your doctor whether you’ve ever had an Lp(a) test and whether one should be added to your next bloodwork order.

6. Your calcium score
Sometimes, your cholesterol and other risk factors don’t give your doctor a clear answer about whether you need treatment.
That’s where a coronary artery calcium score can help.
This CT scan looks for calcium in the arteries that supply blood to your heart. Calcium can be a sign that plaque has already started to build up.
But the test isn’t recommended for everyone. Your doctor will consider it when you’re deciding whether to start medication if the benefit remains uncertain.
“A calcium scan can show us whether there are already signs of coronary artery disease,” says Dr. Conner. “That information may make the decision about treatment clearer.”
The scan is only one part of the evaluation. Your doctor will still consider your cholesterol, health history and overall risk before making a recommendation.

7. Your concerns about taking a statin
How comfortable you are with your treatment plan matters.
You may be worried about muscle aches, taking medication long term, or whether lifestyle changes could lower your cholesterol without a prescription.
Make sure you bring those concerns to your appointment.
“Patients should understand why a statin is being recommended and how much it may lower their risk,” says Dr. Conner. “It should be a conversation, not simply a prescription.”
Healthy habits are important whether you take medication or not. But lifestyle changes might not always lower cholesterol enough, especially when inherited risk or existing heart disease is involved.
Side effects also don’t always mean that statin treatment has to end. Your doctor may be able to lower the dose, recommend a different statin, or discuss another cholesterol-lowering medication.

The decision depends on your personal risk
The new statin guidelines don’t mean that everyone needs a statin.
They give your doctor more information to decide who’s most likely to benefit from treatment and when that treatment should begin.
“The goal is to lower a person’s chance of developing heart disease without recommending medication they don’t need,” says Dr. Conner. “That decision should be based on their individual risk.”
Your cholesterol levels are an important part of that decision, but they aren’t the only part. Your health history, inherited risk and long-term outlook can all help determine the right next step.
