Heart Disease And Stroke

Overview

Heart disease and stroke are both conditions that affect the heart and blood vessels. In heart disease, the vessels that supply the heart muscle become narrow or blocked, so the heart may not get enough oxygen. A stroke happens when a blood vessel in the brain becomes blocked or bursts, which can damage brain cells. Both are part of a wider group called cardiovascular disease. Many of the same healthy habits can lower your risk of both.

Yes. Heart disease and stroke are very common. Around the world they are among the top causes of death and long-term disability, and they affect millions of people in the UK and many other countries each year.

Anyone can develop heart disease or stroke, but the risk rises with age. People with high blood pressure, high cholesterol, diabetes, people who smoke, and those with a family history are more likely to be affected. Men tend to develop heart disease at a younger age, while a woman's risk increases after menopause.

Symptoms

Common symptoms

• Chest pain, pressure, tightness, or discomfort that may spread to the arm, neck, jaw, or back.
• Shortness of breath, especially with activity or when lying flat.
• Feeling very tired, lightheaded, or having a fluttering or racing heartbeat.
• Sudden weakness or numbness of the face, arm, or leg, especially on one side of the body.
• Sudden confusion, trouble speaking, or trouble understanding speech.
• Sudden trouble seeing in one or both eyes, dizziness, loss of balance, or a sudden very bad headache.

Symptoms in children

• Heart disease and stroke are rare in children. When they happen, they are usually linked to a heart problem present at birth, a serious infection, or a genetic condition.
• In a child, warning signs may include poor feeding, breathing fast, blue lips or skin, or passing out. These need urgent medical attention.

Symptoms in older adults

• Older adults may have vague symptoms such as unusual tiredness, mild confusion, shortness of breath, or feeling generally unwell.
• Chest discomfort may feel more like indigestion or heaviness rather than sharp pain.
• Stroke signs in older adults can be missed because they may look like weakness or confusion from ageing, but sudden changes always need urgent care.

Causes

Main causes

• A build-up of fatty material called plaque inside the arteries, which narrows them and reduces blood flow.
• High blood pressure, which over time damages blood vessels and makes heart attacks and strokes more likely.
• A blood clot that blocks an artery in the heart, causing a heart attack, or in the brain, causing a stroke.
• A burst blood vessel in the brain, which can cause a stroke.
• Some irregular heart rhythms, which can allow a clot to form and travel to the brain.

Risk factors

• Smoking or using tobacco.
• High blood pressure.
• High cholesterol.
• Diabetes or pre-diabetes.
• Being overweight or obese.
• Not being physically active.
• Eating a diet high in saturated fat, salt, and processed foods.
• Drinking too much alcohol.
• A family history of heart disease or stroke.
• Older age.
• Long-term stress and poor sleep.

When to see a doctor

See a doctor urgently if:

• If you have any of the emergency symptoms listed above, call your local emergency number immediately.
• If you had a brief episode of stroke symptoms that went away, see a doctor the same day, even if you feel fine.
• If you have new or worsening chest discomfort, breathlessness, or fainting, get same-day medical advice.

Book a routine appointment if:

• If you are worried about your personal risk, ask your doctor or nurse about a heart health check.
• If you have a family history of heart disease or stroke, discuss screening and lifestyle changes.
• If you have high blood pressure, high cholesterol, or diabetes, keep regular appointments to monitor your condition.

Diagnosis

Doctors diagnose heart disease and stroke by listening to your symptoms, asking about your health and family history, and carrying out a physical exam. They may also order tests to look at how your heart and blood vessels are working. For a suspected stroke, brain imaging is usually done urgently.

Tests that may be done

• Blood pressure measurement, which is simple and very important.
• Blood tests to check cholesterol and blood sugar levels.
• Electrocardiogram, also called an ECG, which records the electrical activity of the heart.
• Echocardiogram, an ultrasound scan of the heart.
• CT or MRI scans of the brain if a stroke is suspected.
• Angiography, a test that uses dye and X-rays to look at blood vessels.
• A stress test, which checks how the heart responds to exercise.

What to expect at your appointment

You may need a few different tests, sometimes over more than one appointment. The team will explain each step and share the results with you. For a stroke, you may be seen quickly in hospital because acting fast is important. You are welcome to ask questions at any point.

Treatment

Treatment aims to prevent further problems, relieve symptoms, and help you recover. It usually includes lifestyle changes, medicines to manage risk factors such as high blood pressure or high cholesterol, and sometimes procedures to improve blood flow. Your care team will tailor the plan to you.

Self-care at home

• If you smoke, seek help to stop. This is one of the most powerful steps you can take.
• Take any medicines exactly as prescribed and attend follow-up appointments.
• Aim for regular gentle activity, as advised by your doctor or rehabilitation team.
• Learn to recognise your own warning signs and have a plan for what to do.
• Manage stress with relaxation, talking to someone, or activities you enjoy.
• Limit alcohol and follow a heart-healthy eating pattern.

Medical treatments

Medical treatment may include medicines that lower blood pressure, reduce cholesterol, prevent blood clots, or help the heart pump more easily. Some people are offered procedures to open blocked arteries, such as placing a small tube called a stent, or surgery to bypass badly blocked vessels. For stroke, treatment may include clot-dissolving treatment given in hospital and rehabilitation such as physiotherapy, speech therapy, and occupational therapy. Always discuss the benefits and risks with your healthcare provider.

When is surgery considered?

Surgery may be considered when arteries are severely narrowed or blocked and medicine alone is not enough. Examples include opening a blocked artery or bypassing it. For some strokes, a procedure may be used to remove a clot. The need for surgery is decided by a specialist team based on your individual situation.

Living with this condition

Living well with heart disease or after a stroke means finding a new rhythm. You may need to build rest into your day, take medicines regularly, and adjust your routine to save energy. Many people benefit from cardiac rehabilitation or stroke rehabilitation, which helps you regain strength and confidence.

Lifestyle tips

• Keep active within your ability. Little and often can help.
• Follow a heart-healthy eating pattern with plenty of vegetables, fruits, whole grains, and healthy fats.
• Take medicines on time and keep a simple list of them.
• Stop smoking and avoid second-hand smoke.
• Keep appointments and ask for help when you need it.
• Pace yourself and plan tasks to avoid getting overtired.

Diet and exercise

Aim for a balanced diet that is low in added salt, sugar, and saturated fat. A Mediterranean-style way of eating, rich in vegetables, fruits, beans, nuts, fish, and olive oil, is often recommended. For exercise, walking, cycling, swimming, or gentle strength exercises are good options. If you have had a heart attack or stroke, start with guidance from your rehabilitation team and build up gradually.

Mental health and emotional wellbeing

A diagnosis of heart disease or stroke can affect your mood. It is common to feel anxious, low, or frustrated, and some people may lose confidence. These feelings matter. Talk to your doctor or nurse if you feel down, worried, or overwhelmed. Support is available and can make a real difference.

Prevention

Yes. While you cannot change your age or family history, many heart attacks and strokes can be prevented by taking care of the risk factors you can control. This means not smoking, staying active, eating well, keeping a healthy weight, limiting alcohol, and managing high blood pressure, high cholesterol, and diabetes. Regular health checks can catch problems early.

Screening programmes

In many areas, adults over a certain age are offered a heart health check that includes blood pressure, cholesterol, and blood sugar. Ask your GP practice or local health service whether you are due for a check.

Complications

If left untreated

• Heart attack, which is permanent damage to the heart muscle from a blocked artery.
• Stroke, which can cause long-term weakness, speech problems, or memory issues.
• Heart failure, where the heart becomes too weak to pump blood well.
• An irregular heart rhythm, which can increase the risk of another stroke.
• Reduced quality of life, anxiety, or depression.

Long-term outlook

The outlook depends on how quickly you get treatment and your overall health, but there is real reason for hope. Many people survive heart attacks and strokes and go on to live full, active lives. With good medical care, rehabilitation, and healthy changes, you can reduce the chance of further problems and feel better over time.
