Statins lower LDL cholesterol and reduce the risk of heart attack, stroke and other cardiovascular events, and their benefits usually outweigh the risks for people with elevated cardiovascular risk. We explain what statins do, who is most likely to benefit, what side effects to watch for, and how we make treatment decisions as preventive cardiologists.
What are statins and how do they work
Statins are medicines that reduce production of cholesterol in the liver and increase removal of low density lipoprotein cholesterol, or LDL, from the blood. By lowering LDL and stabilizing atherosclerotic plaque, statins reduce the likelihood that plaque will rupture and cause a heart attack or ischemic stroke. They are prescribed widely for both primary prevention, to lower future risk in people without prior cardiovascular events, and secondary prevention, to reduce recurrent events in people with established coronary artery disease.
Why statins matter for heart health in New York
High cholesterol and atherosclerotic disease are common in adults across Manhattan, the Bronx, Queens, Brooklyn, Westchester, Long Island, New Jersey and the greater New York area. Because our practice focuses on prevention, we use statins as one of several tools to reduce risk for middle aged and older adults, people with diabetes, hypertension patients, and anyone with a family history of premature heart disease. Statins are often part of a broader plan that includes lifestyle changes, blood pressure control and targeted testing.
Key concepts at a glance
- Primary versus secondary prevention. Primary prevention refers to using statins before someone has had a heart attack or stroke. Secondary prevention is treatment after a cardiovascular event to prevent another one.
- Risk based decisions. We decide on statin therapy by estimating cardiovascular risk using clinical factors, test results and imaging where appropriate.
- Intensity of therapy. Statins are prescribed at different intensities, from moderate to high, depending on risk and LDL targets.
- Monitoring and safety. Routine monitoring of symptoms and selected labs helps detect uncommon side effects while preserving benefit.
- Shared decision making. We weigh benefits and possible side effects with each patient, considering preferences and other medical conditions.
Who should consider statin therapy
Statins are appropriate for several groups of patients, depending on their overall cardiovascular risk. We evaluate each person individually, but common scenarios include:
Common indications we consider
- People with established atherosclerotic cardiovascular disease, such as prior heart attack or ischemic stroke.
- Adults with LDL cholesterol persistently above guideline thresholds despite lifestyle measures.
- Adults with diabetes between certain ages, where risk is elevated even without prior events.
- Adults with multiple risk factors, including hypertension, smoking, family history of premature coronary disease, or elevated coronary artery calcium on imaging.

Benefits of statins
Statins reduce LDL cholesterol and lower the risk of heart attack, ischemic stroke and the need for coronary procedures in people at increased risk. In patients who already have coronary artery disease, statin therapy reduces the chance of another heart attack or other major cardiovascular event. The decision to start statins is based on the balance between that risk reduction and the probability of side effects for a particular patient.
Major cardiology organizations provide guidance on when to use statins and how to estimate risk. For general guideline summaries, see the American College of Cardiology and American Heart Association recommendations, and the U.S. Food and Drug Administration safety information on statin medicines.
Common and uncommon risks and side effects
Most people tolerate statins well. The side effects we discuss most often are:
- Muscle symptoms. Muscle aches or weakness occur in some patients. We assess severity and timing, and may try a different statin or adjust the dose.
- Liver enzyme elevations. Mild, transient increases in liver enzymes can occur. We check baseline labs and recheck as indicated.
- New onset diabetes risk. Small increases in blood sugar or a slightly higher risk of developing diabetes have been observed in some groups, usually outweighed by reduced cardiovascular risk.
- Rare serious problems. Severe muscle injury and significant liver injury are rare. Monitoring and prompt reporting of symptoms reduce risk.
Most side effects are manageable. When a symptom arises, we review timing, medical history and other medicines before changing therapy. Sometimes switching statins, reducing dose, or trying alternate dosing schedules resolves the issue.
How we decide and monitor treatment
Our process combines risk assessment, testing, and follow up. We never base a decision on a single lab value alone. A typical approach includes:
- Risk assessment. We estimate your 10 year and lifetime cardiovascular risk using clinical factors, and consider tests such as coronary artery calcium when the decision is uncertain.
- Shared decision making. We explain expected benefits, possible side effects, monitoring plans and alternatives so you can weigh options.
- Baseline testing. This generally includes a lipid panel and select labs. We review medications and conditions that affect risk.
- Start and monitor. After starting therapy, we recheck lipids to confirm response, and ask about symptoms. We adjust intensity to meet goals while minimizing side effects.

Common questions patients ask
Below are concise answers to questions we hear regularly.
- Will I need a statin for life Not always. Many people remain on long term therapy for ongoing risk reduction, especially after a heart attack. For others with lower risk, we reassess periodically and may stop medication if appropriate.
- Can lifestyle changes replace statins Lifestyle measures, including diet, exercise, weight management and smoking cessation, are essential. For many people with high risk, lifestyle alone may not lower risk sufficiently, and statins are an important addition.
- Are all statins the same No. Statins differ in potency, dosing, potential interactions and how they are metabolized. We choose the right agent and dose for each patient.
- What if I have muscle pain We evaluate timing and severity, check labs if indicated, and often trial a different statin or dose. Many patients tolerate an alternative medication without recurrence.
Comparing options and alternatives
Statins are the first line therapy for lowering LDL cholesterol. Alternatives or additions are considered when statins are not tolerated or when LDL targets are not reached.
| Medication class | When we consider it |
|---|---|
| Statins | First line for most people who need LDL lowering. |
| Non statin lipid lowering agents, such as ezetimibe or PCSK9 inhibitors | Added when statins are insufficient or not tolerated, or when very low LDL goals are required in high risk patients. |

Key takeaway
Key takeaway
Statins are a foundational therapy to reduce heart attack and stroke risk for people at elevated cardiovascular risk. Decisions about starting, stopping or adjusting statins are individualized, based on risk assessment, testing and careful monitoring.
Frequently asked questions
How quickly do statins lower cholesterol
LDL cholesterol typically falls within a few weeks of starting therapy, and we usually recheck lipids after four to twelve weeks to assess response and adjust dose if needed.
Can I take statins if I have liver disease
We evaluate liver function and the type and severity of liver disease before starting statins. Many patients with stable liver conditions can safely take statins with appropriate monitoring, but we individualize the plan.
What should I do if I get muscle pain
Tell your clinician about the symptom. We review timing, severity and other medicines, check relevant labs if indicated, and may try a different statin or dosing approach. Most patients can be managed without long term harm.
Are there interactions with other medicines
Yes, some medicines can interact with certain statins and affect blood levels. We review all prescriptions, over the counter medicines and supplements to avoid important interactions.
