Chronic Inflammation and Heart Disease: Understanding the Link

Chronic inflammation and heart disease are closely connected. Inflammation helps the body recover from injury or infection. However, when it continues over time, it can contribute to processes that damage blood vessels and affect cardiovascular health.[nature][ncbi.nlm.nih]

High cholesterol, high blood pressure, diabetes, and smoking still matter. Inflammation adds another part to the picture—it does not replace these established risk factors.[academic.oup][heart]

Research into an inflammatory blood marker called GlycA is helping scientists understand this relationship. Here is what the evidence shows and what it means for everyday heart health.

Key Takeaways

• Chronic inflammation can contribute to atherosclerosis, the buildup of plaque inside arteries.[ncbi.nlm.nih]
• A large UK Biobank study linked higher GlycA levels with changes in heart structure and a higher rate of serious cardiovascular events. The findings do not prove cause and effect.[academic.oup]
• Healthy eating, regular activity, avoiding tobacco, and adequate sleep support cardiovascular health.[heart]
• Medical advice should be personalized. Symptoms, health conditions, family history, and treatment needs differ from person to person. Discuss your individual risk with a qualified healthcare professional.

What Is Chronic Inflammation?

Inflammation is part of the immune system’s defense response. It helps the body recognize harmful substances, fight infections, and begin healing.[ncbi.nlm.nih]

There are two main forms:

• Acute inflammation develops quickly after an injury or infection. It usually settles as the problem improves.
• Chronic inflammation lasts for months or years. It may occur with ongoing infections, autoimmune conditions, exposure to irritants, or other health problems.[ncbi.nlm.nih]

Low-grade inflammation can also be associated with factors such as excess body fat, smoking, physical inactivity, and psychological stress. However, it is not one disease with a single cause or a universal treatment.[nature][ncbi.nlm.nih]

How Are Chronic Inflammation and Heart Disease Linked?

Atherosclerosis develops when cholesterol and other substances accumulate within artery walls. Inflammation participates in this process and can influence how plaques develop and behave.[academic.oup][ncbi.nlm.nih]

In simple terms:

1. Cholesterol-containing particles accumulate within an artery wall.
2. Immune cells respond and contribute to plaque development.
3. Inflammatory activity can make some plaques less stable.
4. If a plaque breaks open, a blood clot may form and block blood flow.

A blockage in a coronary artery can cause a heart attack. A blockage affecting blood supply to the brain can cause an ischemic stroke. Not all strokes occur this way; some result from bleeding rather than a blocked artery.[ncbi.nlm.nih][newsroom.heart]

This is why cardiovascular prevention considers several factors together, rather than relying on cholesterol or an inflammation test alone.[academic.oup][heart]

What Did the GlycA Study Find?

A study published in the European Journal of Preventive Cardiology on September 18, 2026, examined data from 488,079 UK Biobank participants. Researchers used GlycA, a blood-based signal reflecting several inflammation-related proteins, to investigate cardiovascular risk.[academic.oup]

Higher GlycA Was Linked to More Cardiovascular Events

Participants in the highest fifth of GlycA levels had a 43% higher adjusted relative hazard of a major cardiovascular event than those in the lowest fifth. The reported hazard ratio was 1.43.[academic.oup]

The study’s combined outcome included:

• Heart attack.
• Heart failure.
• Stroke or other cerebrovascular events.
• Cardiac arrest.
• Cardiovascular death.[academic.oup]

The 43% figure describes a relative comparison between groups. It does not mean that 43% of people with high GlycA had an event, or that an individual’s absolute risk increased by 43 percentage points.

Higher GlycA Was Also Linked to Heart Changes

In an imaging subgroup of 70,809 participants, higher GlycA was associated with smaller heart chamber volumes, thicker left ventricular walls, and poorer filling between heartbeats.[academic.oup]

These findings help researchers explore how inflammation may relate to changes in heart structure and function. They do not mean everyone with a raised inflammatory marker has heart damage or will develop heart failure.[academic.oup]

What Are the Study’s Limits?

This was an observational study. Researchers identified relationships between inflammation markers, heart measurements, and later health outcomes. They did not randomly assign participants to a treatment that lowered GlycA.[academic.oup]

Therefore, the study does not establish that:

• GlycA itself directly causes heart disease.
• Lowering GlycA will prevent a heart attack or stroke.
• Everyone should have GlycA testing.

Most participants were White, which also matters when considering how well the findings apply to other populations.[academic.oup]

What Factors Are Associated With Chronic Inflammation?

Excess Body Fat

Body fat can release substances involved in inflammation. In the GlycA study, greater trunk fat mass was strongly associated with higher inflammatory marker levels.[academic.oup][ncbi.nlm.nih]

However, trunk fat and visceral fat are not interchangeable terms. Trunk fat refers to fat in the torso region; visceral fat specifically surrounds internal organs. The original finding should not be described as measuring only visceral fat.

Smoking

Smoking is associated with inflammation and cardiovascular harm. Current smoking was among the strongest factors associated with higher GlycA in the study.[academic.oup][ncbi.nlm.nih]

Psychological Stress and Social Conditions

Psychological distress and socioeconomic disadvantage were also associated with higher GlycA. This highlights that cardiovascular health involves more than individual choices: living conditions and access to support can matter too.[academic.oup]

Physical Inactivity and Poor Sleep

Physical inactivity and sleep problems are associated with chronic inflammation. Regular movement and adequate sleep are also important parts of cardiovascular prevention.[nature][ncbi.nlm.nih][heart]

Everyday Habits That Support Heart Health

You do not need an extreme “anti-inflammatory” routine. Start with established cardiovascular health measures.

1. Choose a Balanced Eating Pattern

Build meals around vegetables, fruits, whole grains, beans, lentils, nuts, and appropriate sources of protein. Choose unsaturated fats and limit sugary drinks, trans fats, and foods high in salt.[heart]

Avoid assuming that all vegetable oils cause inflammation. Omega-6 fats are essential nutrients, and evidence does not support labeling them as inherently harmful to the heart when eaten as part of a balanced diet.[mayoclinic]

2. Move Regularly

The American Heart Association recommends at least 150 minutes of moderate-intensity activity or 75 minutes of vigorous activity each week for adults. Brisk walking is one practical option.[heart][heart]

Choose activities suited to your abilities. If you have a heart condition, significant symptoms, or limited mobility, ask your healthcare professional what level of exercise is appropriate.

3. Avoid Tobacco

Avoiding nicotine exposure is one of the American Heart Association’s key measures for cardiovascular health. If you smoke, include quitting support in your prevention plan.[heart]

4. Get Enough Sleep

Most adults need seven to nine hours of sleep each night. Consistent, adequate sleep supports cardiovascular health and general well-being.[heart]

5. Manage Established Risk Factors

Do not focus on inflammation while overlooking blood pressure, cholesterol, or blood sugar. These remain central to heart disease and stroke prevention.[heart]

Lifestyle changes and prescribed treatment can work together. A healthy diet is not a reason to stop medication without medical advice.

Should You Ask About Inflammation Testing?

High-sensitivity C-reactive protein, or hs-CRP, is a blood marker that can help assess inflammation. However, it is not specific to artery disease. Infection, injury, and other conditions may also raise it.[ncbi.nlm.nih]

GlycA is another marker being studied for cardiovascular risk assessment. The 2026 findings support further research, but they do not establish a need for universal testing.[academic.oup]

Ask your clinician whether any additional test would change your care. A useful assessment considers your medical history, blood pressure, cholesterol, blood sugar, smoking status, and other relevant factors—not one laboratory result in isolation.[heart]

Medical Advice Should Be Personalized

Every person’s symptoms and health risks are different. Some people have inflammatory conditions with noticeable symptoms, while others may have abnormal markers without obvious warning signs. Symptoms alone cannot confirm chronic inflammation or determine cardiovascular risk.[ncbi.nlm.nih]

A qualified healthcare professional can help you:

• Review your symptoms and medical history.
• Assess established cardiovascular risk factors.
• Decide whether testing is appropriate.
• Set realistic activity, nutrition, and weight-management goals.
• Review whether medicines or supplements are suitable.

Do not use an “anti-inflammatory” supplement as a substitute for medical assessment or prescribed treatment.

Heart Attack and Stroke Symptoms Need Urgent Care

Possible heart attack symptoms include chest pressure or discomfort, shortness of breath, discomfort in the arms or jaw, cold sweats, nausea, or lightheadedness. Symptoms can vary, and some heart attacks begin with mild discomfort.[heart]

For stroke, remember FAST:

• Face: One side droops or feels numb.
• Arms: One arm becomes weak or drifts downward.
• Speech: Speech becomes slurred or difficult.
• Time: Call your local emergency medical service immediately.[international.heart]

Seek emergency help even if stroke symptoms disappear. Do not wait for an inflammation test or a routine appointment.[international.heart]

Frequently Asked Questions

Can chronic inflammation increase heart disease risk?

Chronic inflammation contributes to processes involved in atherosclerosis. Higher inflammatory marker levels are also associated with greater cardiovascular risk, although an individual’s risk depends on many factors.[academic.oup][ncbi.nlm.nih]

Does high GlycA mean I will have a heart attack?

No. GlycA is a marker, not a prediction that a particular event will happen. The study identified a difference in outcomes between groups; it did not establish certainty for individuals.[academic.oup]

Can lifestyle changes replace heart medication?

Do not replace prescribed treatment with lifestyle changes on your own. Cardiovascular prevention may involve both healthy habits and treatment for conditions such as high blood pressure, abnormal cholesterol, or diabetes.[heart]
