Warning signs: when to call 999
Call 999 if you think someone is having a heart attack or stroke. Heart attack warning signs include tight or squeezing chest pain, pain spreading to the arms, neck or jaw, or severe difficulty breathing. Symptoms can vary; they do not always look dramatic. Do not drive yourself to A&E. Follow the call handler’s instructions.
For stroke, remember FAST: Face - a drooping face or uneven smile; Arms - weakness or difficulty keeping both arms raised; Speech - slurred or confused speech; Time - call 999. Other sudden symptoms can also occur. Call 999 for signs of stroke within the last 24 hours even if they have stopped.
This page and its contact form cannot assess symptoms or arrange urgent care. The NHS pages below explain emergency signs in more detail. For a health concern that is not an emergency, contact an appropriate NHS service rather than sending medical details to this site.
What arteries do
Arteries carry blood away from the heart. Most take oxygen-rich blood to the body’s tissues; the pulmonary arteries are the important exception, taking blood from the heart to the lungs to pick up oxygen. Veins carry blood back towards the heart.
The heart muscle needs its own blood supply too. Coronary arteries run over its surface and deliver the oxygen and nutrients it needs to keep pumping. An artery is a living blood vessel, not simply a rigid pipe: its walls and the way blood flows through it both matter.
Cardiovascular disease is an umbrella term for conditions affecting the heart and blood vessels. It includes several different problems, so a diagnosis of one condition does not mean that someone has all of them. Understanding the name of your own condition is a useful starting point for a conversation with your care team.
Plaque, narrowing and heart disease
Atherosclerosis is the build-up of fatty material, often called plaque or atheroma, within artery walls. It develops over time and can narrow the space available for blood flow. Many people have no obvious symptoms while this process is developing.
When the coronary arteries are affected, the condition is called coronary heart disease. Reduced blood supply to the heart muscle can cause angina. A plaque can also rupture and trigger a blood clot that blocks blood flow, causing a heart attack. Problems in other arteries can affect the brain or the blood supply to the legs. Not every heart condition or stroke has the same cause.
Symptoms alone cannot show how healthy your arteries are, and a general guide cannot diagnose a blockage. If you have concerns, seek medical assessment. New or emergency symptoms need prompt action, rather than waiting for a routine prevention appointment.
Know the factors that affect your risk
Risk is shaped by several things together. Smoking, high blood pressure, high cholesterol and diabetes can increase the likelihood of cardiovascular disease. Age and family history also matter. Having a risk factor is not a prediction that a heart attack will happen, but it can identify an opportunity to reduce risk.
High blood pressure often causes no symptoms, so checking it is more useful than waiting to feel unwell. High cholesterol usually has no symptoms either and is checked with a blood test. Ask a healthcare professional what your results mean in the context of your overall health.
Tell your GP about heart or circulatory disease in close relatives, particularly when it occurred at a young age. If you already have diabetes, kidney disease or a cardiovascular diagnosis, use your regular care reviews to discuss prevention. A single number or online quiz does not replace that broader assessment.
Food, smoking and everyday choices
A heart-healthier eating pattern is about what you eat regularly, rather than a single special ingredient. The NHS Eatwell Guide emphasises a balance across food groups, including vegetables, fruit, higher-fibre starchy foods and sources of protein. You can work towards that balance over a day or week, rather than trying to make every meal perfect.
NHS coronary heart disease advice recommends reducing salt and saturated fat. Practical changes might include comparing labels on foods you buy often, choosing higher-fibre versions and using unsaturated oils in place of some butter. Choose changes that fit your budget and preferences; a qualified professional can help if you have specific dietary needs.
If you smoke, stopping is an important step for heart health. You do not have to rely on willpower alone: NHS stop-smoking support can help you choose an approach and manage cravings. If you drink alcohol, follow NHS advice on cutting down and avoiding binge drinking. Risk reduction is worthwhile even when change takes time.
Move more, in a way that suits you
Regular physical activity supports heart and circulatory health. For adults aged 19 to 64, NHS guidance recommends at least 150 minutes of moderate activity or 75 minutes of vigorous activity a week, alongside strengthening activities on at least two days. Breaking up long periods of sitting is useful too.
Brisk walking, cycling and dancing are examples of moderate activity. Start at a level that is appropriate for you and build up gradually; smaller sessions can be easier to fit into everyday life. The aim is a routine you can sustain, not a competition.
Speak to your GP first if you have not exercised for some time, have medical conditions or are unsure what is suitable. If you are recovering from a heart attack or have an exercise plan from a care team, follow that individual advice rather than substituting a general target from this page.
Health checks and treatment decisions
In England, the NHS Health Check programme is for eligible people aged 40 to 74, usually every five years. It has exclusions, including several existing conditions and some current treatments; the NHS eligibility page gives the full details. People with an existing diagnosis may need regular condition-specific reviews instead. Elsewhere in the UK, ask your GP about the prevention services available locally.
A check can include blood pressure, cholesterol and a discussion of lifestyle and family history. The purpose is to understand risk and agree useful next steps, not simply collect a score. Do not wait for an invitation if you have symptoms or an immediate concern.
Lifestyle support and medicines can both have a role. NICE guidance supports discussion of cardiovascular risk, lifestyle changes and statin treatment where appropriate. A clinician can explain likely benefits, possible harms and your preferences. Do not start, stop or change prescribed treatment on the basis of this guide.
Make your next conversation useful
Before a routine appointment, write down your questions, current medicines and any relevant family history. You might ask what your blood pressure and cholesterol results mean, which change would help most, whether treatment is worth considering and when the results should be reviewed. Ask for an explanation in everyday language if anything is unclear.
If you have already had a heart attack, ask about cardiac rehabilitation and ongoing support. Prevention does not end at diagnosis: care can include recovery, managing symptoms and lowering the risk of another event.
