Heart Disease Risk Factors
Overview
Heart disease is a group of conditions that affect the heart and blood vessels. Risk factors are things that make heart disease more likely. They are not a diagnosis. Having one or more risk factors does not mean you will get heart disease, and not having them does not mean you are safe. The good news is that many risk factors can be lowered.
Key facts
- Some risk factors, like age and family history, cannot be changed. Many others, like smoking and high blood pressure, can be managed.
- Risk factors often cause no symptoms, so regular checks matter.
- Small, steady changes to daily habits can make a real difference to heart health.
Heart disease is one of the most common health problems worldwide. Many adults have at least one risk factor, even if they feel well.
It affects people of all ages, sexes, and backgrounds. Risk rises with age and is higher in some families and communities. Children can also start building heart-healthy habits early.
Symptoms
- Call your local emergency number immediately if you have chest pain or pressure that lasts more than a few minutes, or comes and goes, especially with sweating, nausea, or shortness of breath.
- Call emergency services for sudden shortness of breath or severe trouble breathing.
- Call emergency services for fainting or near-fainting.
- Call emergency services for face drooping, arm weakness, or speech trouble - these can be signs of a stroke.
- Call emergency services for a very fast or irregular heartbeat with dizziness, chest pain, or fainting.
- ⚠New or worsening breathlessness when doing light activity.
- ⚠New swelling in your ankles, feet, or legs.
- ⚠Palpitations that are new, frequent, or uncomfortable.
- ⚠Unusual tiredness or weakness that is getting worse.
- ⚠A home blood pressure reading that is very high, as advised by your clinician.
Common symptoms
- Risk factors themselves usually cause no symptoms.
- If heart disease develops, possible symptoms include chest pain, pressure, or tightness.
- Shortness of breath, especially with activity.
- Unusual tiredness or low energy.
- Palpitations - a feeling that your heart is racing, fluttering, or skipping a beat.
- Swelling in the ankles, feet, or legs.
Symptoms in children
- Children usually do not have symptoms from heart disease risk factors.
- Risk factors can start early, so family habits around food, movement, and smoke-free homes matter.
- A child with a strong family history or a health condition such as diabetes should be checked as advised by their clinician.
Symptoms in older adults
- Risk rises with age.
- Symptoms may be milder or less typical, such as tiredness, breathlessness, confusion, or poor mobility rather than chest pain.
- Regular reviews of blood pressure, cholesterol, and medicines are important.
Causes
Main causes
- Heart disease often develops when fatty deposits build up inside the arteries that supply the heart. This can narrow or block blood flow.
- Sometimes the heart muscle, valves, or rhythm are affected for other reasons.
- Risk factors are things that raise the chance of these problems. They can be related to genes, age, health conditions, and daily habits.
Risk factors
- Smoking or breathing in other people's smoke
- High blood pressure
- Unhealthy cholesterol levels
- Type 2 diabetes or prediabetes
- Overweight or obesity, especially extra weight around the waist
- Not being active enough
- A diet high in salt, saturated fat, and added sugar, and low in fruit, vegetables, and fibre
- Drinking too much alcohol
- Poor sleep or untreated sleep apnoea
- Long-term stress and feeling isolated
- Kidney disease
- Family history of early heart disease
- Age - risk rises as you get older
- Some ethnic backgrounds have higher risk, including South Asian, African, and Caribbean backgrounds in the UK
- Pre-eclampsia or diabetes during pregnancy
- Inflammatory conditions such as rheumatoid arthritis or lupus
When to see a doctor
See a doctor urgently if:
- New shortness of breath or breathlessness that is getting worse.
- New swelling in the ankles, feet, or legs.
- Palpitations that are new, fast, or frequent.
- Feeling very tired or weak with no clear reason, especially if it is new.
- A home blood pressure reading that is very high, as advised by your clinician.
Book a routine appointment if:
- You want to know your heart disease risk.
- You have a family history of early heart attack or stroke.
- You have high blood pressure, high cholesterol, diabetes, or kidney disease.
- You smoke and want help to stop.
- You are overweight and want support.
- You have questions about diet, exercise, or alcohol.
- You are due for a routine health check.
Diagnosis
A clinician will ask about your health, family history, and daily habits. They may check your blood pressure, weight, and pulse, and order blood tests. They may use a risk score to estimate your chance of heart disease over the next 10 years. This is not a test for whether you have heart disease right now.
Tests that may be done
- Blood pressure check
- Blood tests for cholesterol, blood sugar, and kidney function
- Weight, waist measurement, and body mass index (BMI)
- A heart tracing (ECG) if you have symptoms
- A risk score, such as a QRISK score in the UK, using your details
- Further tests only if your clinician thinks they are needed
What to expect at your appointment
The check is usually quick and painless. You may need to fast for some blood tests - ask the clinic beforehand. Your clinician will explain your results and talk with you about next steps. You can ask questions and take someone with you if that helps.
Treatment
Treatment for heart disease risk factors focuses on lowering your chance of heart attack, stroke, and other problems. It is not about blame. Your clinician will help you choose steps that fit your life. Many people improve their risk with a mix of daily habits, regular checks, and medicines when needed.
Self-care at home
- Choose one small change to start, such as a short daily walk or adding a vegetable to a meal.
- Stop smoking and avoid other people's smoke. Ask your clinician or pharmacist for support.
- Eat more fruit, vegetables, beans, whole grains, nuts, and oily fish. Cut down on salt, sugary drinks, and processed meats.
- Move more. Aim for activity that makes you breathe a little harder, built up slowly.
- Keep alcohol within local health guidance, or drink less.
- Try to get regular sleep and manage stress with breathing, hobbies, or talking to someone.
- Check your blood pressure and cholesterol as advised.
Medical treatments
If lifestyle changes are not enough, your clinician may prescribe medicines to lower blood pressure, lower cholesterol, control blood sugar, or reduce the chance of clots. They will explain why a medicine is suggested, how to take it, and what to watch for. Do not start or stop any medicine without talking to your clinician or pharmacist.
When is surgery considered?
Surgery or procedures are not used to treat risk factors alone. They may be considered if tests show serious heart disease, such as narrowed arteries or a heart valve problem. Your clinician would refer you to a heart specialist to discuss the benefits and risks.
Living with this condition
Living with heart disease risk factors is mostly about steady habits and regular checks. It can feel like a lot at first. Focus on what matters most to you and build support around you. Your plan should fit your culture, budget, and daily life.
Lifestyle tips
- Keep a simple record of your blood pressure, activity, and medicines if you take any.
- Plan meals and snacks ahead so healthy choices are easier.
- Find movement you enjoy, such as walking, dancing, cycling, or gardening.
- Ask family or friends to join you, or join a local group.
- Keep appointments for checks and blood tests.
- Protect your sleep and make time to relax.
Diet and exercise
A heart-healthy way of eating is rich in vegetables, fruit, whole grains, beans, nuts, and fish. It is lower in salt, saturated fat, and added sugar. You do not need a perfect diet. Small swaps, like water instead of sugary drinks or whole grain bread instead of white, can help. For exercise, aim to move most days. Start where you are, even a few minutes at a time, and build up. If you have chest pain, severe breathlessness, or a health condition that limits activity, ask your clinician what is safe for you.
Mental health and emotional wellbeing
Heart health and mental health are linked. Worry, low mood, and stress can make it harder to keep up healthy habits. Feeling judged about weight or smoking can also hurt. These feelings are common, and support is available. If you feel in crisis or have thoughts of harming yourself, contact your local emergency number or a local crisis service right away. You deserve help.
Prevention
You cannot control every risk factor, such as age or family history. But many risk factors can be prevented or lowered. Even people with a strong family history can reduce their risk with healthy habits, regular checks, and treatment when needed.
Vaccines
Ask your clinician whether you are due for routine vaccines. Some vaccines, such as flu and pneumonia vaccines, are offered based on age or health conditions. Vaccines do not prevent heart disease, but they can prevent infections that are harder on the heart.
Screening programmes
Many health systems offer routine checks for blood pressure, cholesterol, and diabetes risk. In the UK, the NHS Health Check is offered to adults in certain age groups. Ask your clinician when you are due for a check. Screening can find risk factors early, when they are easier to manage.
Complications
If left untreated
- Heart attack
- Stroke
- Heart failure - when the heart cannot pump as well as it should
- Narrowed arteries in the legs, which can cause pain when walking
- Kidney damage
- Problems with heart rhythm
- Poor blood flow to the brain, which can affect memory and thinking
Long-term outlook
The outlook is hopeful. Many people lower their risk and live full lives by making steady changes and keeping up with checks. If you already have heart disease, treatment and support can help you live well for longer. Small steps taken today can still make a difference.
