Statins to Prevent Heart Attacks: Who Needs Them?

Statins are often prescribed after tests show high LDL cholesterol levels, even when a person still feels healthy and can go about their usual activities. This situation naturally raises questions: why is medication needed if there are no symptoms yet, how much does it benefit the heart, and do statins have to be taken long term?

Statins are a group of prescription medications mainly used to help lower LDL cholesterol. In people with certain indications, they also help reduce the risk of heart attack, stroke, and other problems related to atherosclerosis. However, the treatment decision is not determined by a single cholesterol number alone. Doctors need to consider medical history, risk factors, coexisting conditions, other medications, and the patient’s preferences.

For this reason, statins are not universally right or wrong for everyone. Understanding how they work will help you talk with your doctor in a calmer and more focused way, without starting, switching, or stopping treatment on your own.

01 / Cardiovascular Therapy

What Are Statins?

Statins are a group of prescription medications that help lower LDL cholesterol by reducing cholesterol production in the liver and increasing the removal of LDL from the bloodstream. They are used to manage cholesterol and help prevent cardiovascular events in patients who benefit from this therapy.

What Is the Main Function of Statins?

The main function of statins is to help lower low-density lipoprotein, or LDL. LDL is often called “bad cholesterol” because too much of it can contribute to plaque buildup in the walls of blood vessels.

Even so, the goal of therapy is not just to make lab results look better. In certain patients, lowering LDL is part of a long-term strategy to help reduce the risk of:

• heart attack;
• stroke;
• coronary heart disease;
• peripheral artery disease;
• recurrent cardiovascular events.

Statins can also affect triglycerides and HDL to some degree. However, the main focus of therapy generally remains on lowering LDL and managing cardiovascular risk.

Statins do not relieve symptoms. They are not used to immediately get rid of chest pain, shortness of breath, or fatigue. Their benefits build up through consistent use according to the treatment plan.

Are All Cholesterol Medications Statins?

No. Statins are only one group of medications that lower lipids, or fats, in the blood.

Examples of statins include:

• simvastatin;
• atorvastatin;
• rosuvastatin;
• pravastatin;
• fluvastatin;
• pitavastatin.

In certain situations, doctors may consider lipid-lowering medications from other groups, either as a replacement or as an addition. The choice depends on the patient’s risk, treatment targets, how the body responds, tolerance, and other medical conditions.

02 / Cardiovascular Therapy

How Statins Work

Statins work mainly in the liver. They slow cholesterol production and help the liver take up more of the LDL already circulating in the blood. As a result, the amount of LDL can decrease and the process of plaque formation in the blood vessels can be slowed.

The Liver’s Role in Cholesterol Production

The body does get some cholesterol from food. However, the liver also produces cholesterol because this substance is needed to build cell membranes, hormones, and various other important components.

Statins block an enzyme called HMG-CoA reductase. Simply put, this enzyme is one of the key parts of the cholesterol production process in the liver.

When the enzyme’s activity is suppressed:

1. cholesterol production in the liver decreases;
2. the liver increases the number of receptors that capture LDL;
3. more LDL is removed from the bloodstream;
4. LDL levels can go down.

How Do Statins Help Lower LDL?

How statins work can be summarized as follows:

The liver produces cholesterol → statins slow production → the liver takes up more LDL from the blood → LDL levels fall → cardiovascular risk may decrease in patients who have an indication.

However, statins do not work like a cleaning fluid that removes all plaque in a short time. They help control the disease process and may help stabilize plaque as part of long-term therapy.

03 / Cardiovascular Therapy

Why Does LDL Need to Be Controlled?

LDL cholesterol needs to be controlled because excessive levels can contribute to plaque buildup in the artery walls. Over time, plaque can narrow blood vessels or trigger the formation of clots that disrupt blood flow to the heart, brain, or other organs.

The Link Between LDL and Plaque in Blood Vessels

The buildup of cholesterol and other components in the artery walls is called atherosclerosis. This process develops slowly and can make blood vessels stiffer or narrower.

Its impact depends on which blood vessels are affected:

• In the coronary arteries, atherosclerosis can cause coronary heart disease or a heart attack.
• In the vessels leading to the brain, this process can increase the risk of stroke.
• In the leg arteries, this condition can be linked to peripheral artery disease.

LDL is not the only factor involved. High blood pressure, diabetes, smoking, inflammation, age, and genetic factors can also affect the development of blood vessel disease.

Why Can Risk Be Present Without Symptoms?

High cholesterol usually does not cause specific symptoms. A person can keep working, exercising, and feeling fit even though their LDL level or cardiovascular risk has increased.

That is why having no symptoms does not mean having no risk. A lipid profile test helps assess conditions that cannot always be felt directly. The American Heart Association also emphasizes that elevated cholesterol levels can raise the risk of heart disease and stroke, so testing is needed to find out where you stand.

This is the difference between treating symptoms and prevention. Statins may be recommended to reduce risk before a heart attack or stroke occurs, not because the patient has to wait for symptoms to appear first.

04 / Cardiovascular Therapy

Who Needs Statins?

Statins are generally considered for people who already have cardiovascular disease, have very high LDL levels, or face increased cardiovascular risk. However, the treatment decision needs to be made through a discussion that weighs the benefits, possible side effects, coexisting conditions, use of other medications, and the patient’s preferences.

Patients With Heart or Blood Vessel Disease

Statins are often part of secondary prevention, which aims to prevent recurrent cardiovascular events in people who already have a disease related to atherosclerosis.

These conditions may include:

• coronary heart disease;
• a history of heart attack;
• certain types of stroke;
• peripheral artery disease;
• a history of heart stent placement;
• other coronary revascularization procedures.

In this context, statins are not only aimed at lowering the LDL number. Therapy also aims to reduce the risk of further problems across the wider network of blood vessels.

People With Very High Cholesterol

Very high LDL levels can be a reason to evaluate treatment, especially if they are found at a young age or come with a family history of early heart disease.

One possible cause is familial hypercholesterolemia, a genetic condition that causes high LDL from early in life. Its assessment does not rely on a single cutoff number, but also considers the full lipid profile, clinical findings, and family history.

People With Increased Cardiovascular Risk

Doctors may also consider statins for people who have never had a heart attack or stroke but have increased risk. This is called primary prevention.

Factors that may be considered include:

• age;
• cholesterol levels;
• hypertension;
• diabetes;
• chronic kidney disease;
• smoking;
• family history;
• body weight and metabolic condition;
• other diseases or medications that affect risk.

Even so, a single factor does not always determine the decision. Risk needs to be assessed as a whole.

Why Is the Decision Not Based on a Single Number?

Imagine two people with the same LDL level.

The first person does not smoke, has no diabetes or hypertension, and has no family history of heart disease. The second person, by contrast, has diabetes and high blood pressure and has had a stent placed.

Their LDL numbers may be similar, but their level of risk and the benefit they may gain from therapy can differ.

That is why guidelines emphasize shared decision-making, in which decisions are made together. The doctor provides information about the benefits and possible risks, while the patient shares their concerns, preferences, and readiness to undergo long-term therapy.

Benefits of Statins for the Heart

The main benefit of statins is helping to lower LDL and reduce the risk of cardiovascular events in people who have an indication. The size of the benefit varies from patient to patient and is generally greater in people with a higher starting risk.

Helping Lower LDL Cholesterol

The response to statins is influenced by several things, including:

• the type and intensity of the statin;
• LDL levels before therapy;
• genetic factors;
• liver and kidney condition;
• taking the medication as prescribed;
• interactions with other medications;
• lifestyle.

For this reason, treatment targets need to be tailored to each patient’s level of risk and clinical goals.

Helping Reduce the Risk of Heart Attack and Stroke

Evidence from various clinical trials shows that lowering LDL through statin therapy is associated with fewer cardiovascular events. An article from the Indonesian Ministry of Health (Kemenkes) summarizing a large meta-analysis states that every reduction in LDL of about 40 mg/dL is associated with a proportional reduction of about 21% in major cardiovascular events.

This figure needs to be understood correctly. It is an average result in a study population, not a guarantee that every person’s risk will fall by the same amount.

A person’s absolute benefit is influenced by their starting risk. For example, the same proportional reduction in risk may provide a greater benefit for a patient who already has heart disease than for someone with a low baseline risk.

Supporting Long-Term Prevention

For busy professionals, prevention is not just about lab results. The goal is to stay healthy so that you can keep working, carry out your activities, and be there for your family in the long term.

However, statins are not the only form of protection. Blood pressure, blood sugar, smoking, physical activity, sleep, diet, and adherence to other therapies still affect overall risk.

06 / Cardiovascular Therapy

Types of Statins

Simvastatin, atorvastatin, and rosuvastatin are some of the commonly used types of statins. All three work through a similar mechanism, but they differ in how strongly they lower LDL, how long they act, their interactions, and the considerations for their use.

The NHS, which updated its simvastatin and atorvastatin pages in 2026, states that simvastatin is usually taken in the evening. Meanwhile, atorvastatin and rosuvastatin can be taken once a day at a consistent time. The instructions on your prescription and medication package remain the main reference.

Note: This table is not a guide for choosing, switching, or adjusting the dose of a statin on your own.

How Do Doctors Choose a Type of Statin?

Doctors may consider:

• how much LDL reduction is needed;
• whether the patient already has cardiovascular disease;
• age and general health;
• liver and kidney function;
• other medications or supplements;
• possible interactions;
• previous experience with side effects;
• the ability to follow therapy consistently.

In other words, no single statin is always the most suitable for everyone. The right choice is a therapy that fits the clinical goals, is safe given the patient’s condition, and can be continued over the long term.

Statin Myths and Facts

Information about statins is often exaggerated, either portraying them as a medication everyone must take or calling them dangerous without context. In fact, their benefits and risks need to be assessed individually.

Myth: Statins Cause Dependence

Fact: Statins do not cause dependence the way addictive substances do.

Some patients need long-term therapy because the underlying disease or risk factors are still present. If cholesterol rises again after the medication is stopped, it is not a sign of addiction. The medication’s LDL-lowering effect has stopped, while the body continues to produce cholesterol.

Myth: Normal Cholesterol Means Statins Must Be Stopped

Fact: Improved cholesterol results may show that the therapy is working.

Before changing the medication, the doctor needs to review:

• the original reason for prescribing the statin;
• any history of cardiovascular disease;
• the current level of risk;
• lifestyle changes;
• tolerance of the medication;
• the latest test results.

So normal results do not automatically mean the underlying risk is gone.

Myth: All Muscle Pain Is Caused by Statins

Fact: Statins can be linked to muscle complaints in some people, but muscle pain has many possible causes.

Physical activity, injury, infection, thyroid disorders, muscle conditions, and other medications can also play a role. The increase in the risk of muscle complaints due to statins is small, while severe muscle disorders such as rhabdomyolysis are very rare.

For this reason, complaints need to be evaluated based on when they appear, where they occur, how severe they are, recent activity, and other medications being used.

Myth: Statins Always Damage the Liver or Kidneys

Fact: Statins can cause changes in liver enzyme test results in some patients. However, actual liver damage is very rare.

Kidney damage can occur as a complication of a severe muscle disorder, but this is also rare. Medical history, symptoms, drug interactions, and test results help the doctor decide on appropriate monitoring.

Myth: Statins Impair Memory

Fact: The available evidence has not shown a convincing link between statins and a lasting decline in thinking ability.

If memory changes occur, the doctor needs to review other possibilities, such as sleep problems, stress, medical conditions, depression, or medications taken at the same time. Do not stop therapy based on suspicion alone without an evaluation.

Myth: A Healthy Lifestyle Can Always Replace Statins

Fact: A healthy lifestyle is the foundation of cardiovascular disease prevention, but it is not always enough for everyone.

Patients with heart disease, familial hypercholesterolemia, or high risk may still need medication. Taking a statin does not mean a person has failed to look after their health.

08 / Cardiovascular Therapy

Side Effects of Statins

Most people can take statins without serious side effects. However, like other medications, statins can cause complaints or interact with certain drugs. The key is to recognize any changes and discuss them with a health professional.

Muscle Complaints

Muscle complaints may include:

• aches or pain;
• cramps;
• a feeling of weakness;
• tenderness;
• reduced ability to do usual activities.

If complaints appear, note:

• when the complaints started;
• which part of the body is affected;
• whether it occurs on one or both sides;
• its intensity and duration;
• any recent physical activity;
• any newly started medications or supplements;
• whether there is fever or a change in urine color.

NICE advises patients to seek an evaluation if they have unexplained muscle pain, weakness, or tenderness. A creatine kinase (CK) test may be considered in patients with symptoms, but it does not need to be done routinely in people without complaints.

Seek medical help immediately if muscle pain or weakness is severe, especially if accompanied by fever or reddish-brown urine. These symptoms may point to a serious muscle disorder, although this is rare.

Liver Function

Before starting a statin, the doctor may assess your history of liver disease, alcohol use, other medications, and liver enzyme levels.

For example, NICE recommends checking the lipid profile and liver enzymes about 2 to 3 months after starting or changing therapy. Liver enzyme tests can be repeated at 12 months, and then again if clinically indicated. The actual schedule may differ depending on the patient’s condition and the guidelines used.

Consult a doctor promptly if you notice:

• yellowing of the skin or the whites of the eyes;
• very dark urine;
• severe abdominal pain;
• persistent nausea;
• unusual fatigue.

Blood Sugar and Diabetes Risk

Statins can raise blood sugar slightly, especially in people who already have a risk of diabetes, such as those with prediabetes, obesity, or metabolic syndrome.

However, this does not mean everyone who takes statins will develop diabetes. Doctors weigh this possible risk against the expected cardiovascular benefits. NICE also does not recommend automatically stopping statins just because blood sugar or HbA1c has increased.

Interactions With Medications, Supplements, Food, and Drinks

Some medications, supplements, and foods can change statin levels in the body and increase the risk of side effects.

For this reason, tell your doctor or pharmacist about:

• all prescription medications;
• over-the-counter medications;
• vitamins;
• herbal remedies;
• supplements;
• treatments from other doctors.

This is also important if you take other heart medications, including beta blockers.

Grapefruit and grapefruit juice can interact with some, but not all, statins. People taking simvastatin need to avoid grapefruit juice, while restrictions for atorvastatin may differ. For this reason, follow the medication leaflet and the guidance of your doctor or pharmacist rather than a general rule applied to all statins.

What If You Are Pregnant or Breastfeeding?

Tell your doctor right away if you are pregnant, think you might be pregnant, are planning a pregnancy, or are breastfeeding.

The FDA states that most pregnant patients should stop taking statins after consulting their doctor. However, the absolute ban for all pregnancies has been removed so that decisions can be tailored in very high-risk cases, such as homozygous familial hypercholesterolemia or severe cardiovascular disease. Breastfeeding is also generally not recommended if statin therapy must be continued.

Do not stop the medication on your own before getting medical advice.

What Should You Do If Complaints Appear?

Take the following steps:

1. Note the type, location, and timing of the complaint.
2. Notice whether there have been any changes in activity, food, medications, or supplements.
3. Contact your doctor or pharmacist.
4. Follow the recommended tests.
5. Do not double, reduce, or stop the dose on your own.

After the evaluation, the doctor may look into other possible causes, change the dose, switch the type of statin, check for interactions, or consider other treatment options. This way, patients do not have to choose between putting up with the complaints and stopping completely without guidance.

09 / Cardiovascular Therapy

How Long Are Statins Used?

How long statins are used differs from person to person. Some patients need them long term, even for life, while others may have their therapy adjusted based on their condition, response to treatment, and treatment goals.

Why Can Therapy Last a Long Time?

Statins help manage risk for as long as they are used. If the underlying condition is still present, such as coronary heart disease, familial hypercholesterolemia, or a history of heart attack, the benefits of therapy may still be needed.

The NHS explains that statins are generally used long term. If the medication is stopped, cholesterol levels may rise again.

This does not mean the body has become dependent. A more fitting analogy is blood pressure management: improved results while on therapy do not necessarily mean the underlying tendency has disappeared.

Can You Stop When Your Cholesterol Is Normal?

Do not stop statins just because one test result shows normal cholesterol.

That result may mean that:

• the medication is working;
• lifestyle changes are having an effect;
• the combination of both has succeeded in controlling LDL.

Before changing therapy, the doctor needs to review the original reason the statin was prescribed and the risk that still remains. This is especially important for patients who have had a heart attack, a stroke, or a stent placed.

Can the Statin Dose Be Adjusted?

Yes, the doctor may consider adjustments based on:

• how LDL levels respond;
• tolerance;
• complaints;
• drug interactions;
• changes in liver or kidney condition;
• prevention goals.

If side effects occur, the options are not always limited to “continuing to take it despite the complaints” or “stopping completely”. The doctor may review the dose, try another type of statin, or consider a different lipid-lowering therapy.

10 / Cardiovascular Therapy

Statins and Lifestyle

Statins do not replace a healthy lifestyle. Medication and daily habits have different roles, but both can work together to manage cardiovascular risk.

The Role of Diet

A heart-healthy diet generally prioritizes:

• vegetables and fruits;
• whole grains;
• nuts and legumes;
• suitable protein sources;
• unsaturated fats;
• limiting saturated fats;
• limiting ultra-processed foods.

There is no need to make extreme changes all at once. A realistic pattern that you can maintain is usually more beneficial than a strict diet that only lasts for a while.

Learn more practical steps in the article on a healthy lifestyle to support heart health.

Physical Activity and Body Weight

Physical activity helps maintain fitness, blood pressure, sugar metabolism, body weight, and mental health. However, the type and intensity of exercise need to be adjusted to your abilities and medical condition.

For professionals with busy schedules, small changes can be a more realistic starting point, for example:

• walking more often;
• reducing long periods of sitting;
• scheduling physical activity;
• taking the stairs when it is safe;
• choosing activities you can do consistently.

If you have heart disease or symptoms during activity, discuss safe types of exercise with your doctor.

Why Do Medication and Lifestyle Need to Go Together?

Statins act on the production and removal of LDL. A healthy lifestyle, on the other hand, provides broader benefits for blood pressure, blood sugar, body weight, fitness, sleep, and mental health.

That is why taking medication is not a sign of failure. At the same time, living a healthy lifestyle is not a reason to stop medication without a medical assessment.

11 / Cardiovascular Therapy

When Should You See a Doctor?

A consultation is needed when you do not yet understand why a statin was prescribed, have complaints during therapy, take many medications, or want a more thorough assessment of your cardiovascular risk.

Before Starting a Statin

Consider a consultation if:

• your medical check-up results show an abnormal lipid profile;
• you do not yet understand the benefits and goals of therapy;
• you have diabetes, hypertension, kidney disease, or several risk factors;
• there is a family history of early heart disease;
• you take many medications or supplements;
• you have had complaints while taking statins before;
• you would like a second opinion.

Before starting therapy, the assessment may include a lipid profile, blood pressure, diabetes status, kidney function, liver enzymes, smoking, alcohol use, and any history of muscle complaints. Tests are tailored to each patient’s needs.

During Therapy

Contact your doctor if:

• new complaints appear;
• you have muscle pain or weakness with no clear cause;
• you are prescribed another medication;
• you start taking herbal remedies or supplements;
• you often forget to take your medication;
• you want to reduce or stop therapy;
• your test results have not reached the goal;
• therapy feels hard to follow consistently.

Open communication helps the doctor find a plan that is both effective and realistic for you.

Symptoms That Need Urgent Help

Statins are not a treatment for an acute heart attack or stroke.

Seek medical help immediately if you experience:

• pain, pressure, or discomfort in the chest that persists or keeps coming back;
• shortness of breath;
• a cold sweat, nausea, or feeling lightheaded;
• pain spreading to the arm, back, neck, jaw, or upper abdomen;
• a drooping face;
• sudden weakness or numbness on one side of the body;
• sudden slurred speech;
• fainting or not responding.

Heart attack symptoms do not always start with very severe pain. For this reason, do not wait for your routine medication to take effect or for a regular appointment if emergency signs appear.

12 / Cardiovascular Therapy

Preparing for Your Consultation

Bringing the right notes will help your doctor understand your condition more quickly and thoroughly.

If available, prepare:

• your latest and previous lipid profile results;
• medical check-up results;
• the name and dose of your statin from the prescription label;
• your schedule and the date you started therapy;
• notes on your complaints and when they appear;
• a list of all prescription and over-the-counter medications;
• vitamins, herbal remedies, and supplements;
• any history of diabetes and hypertension;
• any history of liver, kidney, or thyroid disease;
• any history of heart attack, stroke, or stent placement;
• any family history of heart disease;
• questions you want to discuss.

There is no need to wait until all your data is perfectly complete. Bring the information you have and mention anything you do not yet know.

13 / Cardiovascular Therapy

Conclusion

Statins are a group of medications mainly used to help lower LDL cholesterol. In people who have an indication, this therapy may also reduce the risk of heart attack, stroke, and other cardiovascular events.

However, the need for therapy, the type, the dose, and the duration differ for each patient. Side effects need to be recognized and evaluated properly, not ignored or immediately treated as a reason to stop the medication. In addition, a healthy lifestyle remains an important part of managing heart risk.

By understanding why statins are used, you can take a more active part in discussions with your doctor and make decisions that fit your condition, needs, and long-term health goals.
