heart lifestyle tips for patients

Overview

Your heart is a muscle that pumps blood around your body, carrying oxygen and nutrients to every part. Keeping your heart healthy means making daily choices that help it work well — such as eating well, staying active, managing stress, and avoiding smoking. These tips are important for everyone, especially if you already have a heart or circulation condition.

Yes, heart and circulation problems are very common. Conditions like high blood pressure, coronary heart disease, and heart failure affect millions of people around the world.

Heart problems can affect anyone, but they become more common as we age. Men are often affected at a younger age, and women’s risk rises after menopause. Family history, smoking, diabetes, and unhealthy lifestyle habits also increase your chance of developing heart conditions.

Symptoms

Common symptoms

• Chest pain or tightness (angina), especially during activity
• Shortness of breath, even when resting or with mild effort
• Palpitations — feeling like your heart is racing, fluttering, or skipping beats
• Unusual tiredness or fatigue that does not go away
• Swelling in the ankles, legs, or feet (oedema)
• Dizziness or light-headedness

Symptoms in children

• Children with heart problems may show poor feeding or slower growth in babies
• Tiring easily during play or exercise
• Bluish lips or skin (cyanosis) in some cases
• Rapid breathing or breathlessness

Symptoms in older adults

• Symptoms may be less typical, such as confusion or a sudden drop in energy
• Breathlessness with simple tasks like walking to the shops
• Swelling in the feet or lower legs
• Falls or weakness without a clear cause

Causes

Main causes

• Atherosclerosis — the buildup of fatty plaques inside the arteries, narrowing them and reducing blood flow
• High blood pressure, which puts extra strain on the heart and blood vessels
• High cholesterol, which contributes to artery plaques
• Diabetes, especially if blood sugar is not well controlled
• Smoking or exposure to tobacco smoke, which damages blood vessel walls

Risk factors

• Getting older
• Family history of heart disease or stroke
• Being physically inactive
• Eating a diet high in salt, unhealthy fats, and added sugars
• Carrying excess weight, especially around the waist
• Long-term stress or anxiety
• Drinking too much alcohol

When to see a doctor

See a doctor urgently if:

• If you have new or worsening symptoms such as chest pain, palpitations, or breathlessness, see a doctor the same day.
• If you have diabetes and develop symptoms of a heart problem, seek medical advice promptly.

Book a routine appointment if:

• Even if you feel well, it is worth having a heart health check — especially if you are over 40, have a family history of heart disease, or have high blood pressure, diabetes, or high cholesterol.
• If you have a known heart condition, attend your regular follow-up appointments.

Diagnosis

To find out how well your heart is working, your doctor will ask about your symptoms, medical history, and lifestyle. They will listen to your heart and might talk about your blood pressure, cholesterol, and blood sugar.

Tests that may be done

• Blood pressure measurement
• Blood tests to check cholesterol, blood sugar, and heart strain markers
• Electrocardiogram (ECG/EKG) — a simple test that records the electrical activity of your heart
• Echocardiogram — an ultrasound scan that shows your heart’s structure and pumping action
• Exercise stress test — to see how your heart responds to activity

What to expect at your appointment

These tests are usually painless and quick. You might be asked to expose your chest or wear sticky patches, but you will remain comfortable throughout. After the tests, your doctor will explain the results and discuss next steps — whether that is lifestyle advice, monitoring, or treatment.

Treatment

Heart treatment always starts with lifestyle changes — the same healthy habits that prevent heart disease also help manage it. Depending on your condition, your doctor may also recommend medicines to control blood pressure, cholesterol, heart rhythm, or blood sugar. In some cases, procedures or surgery are needed.

Self-care at home

• Follow a heart-healthy eating pattern, such as the Mediterranean-style diet
• Aim for at least 150 minutes of moderate activity per week, with your doctor's approval
• If you smoke, get help to quit — it is the single best thing you can do for your heart
• Limit alcohol to within recommended national guidelines
• Manage stress through breathing exercises, mindfulness, or talking to a counsellor
• Take medicines exactly as prescribed and track your blood pressure at home if advised

Medical treatments

Your doctor may prescribe medicines to reduce blood pressure, lower cholesterol, prevent blood clots, or control an irregular heartbeat. Always take them as told, and ask your pharmacist or doctor if you have side effects. Never change or stop a heart medicine without your doctor’s advice.

When is surgery considered?

If medicines and lifestyle changes are not enough, surgery may be suggested. This could include procedures to open blocked arteries (such as angioplasty or bypass surgery), repair a heart valve, or implant a pacemaker. Your cardiologist will explain the options and help you decide what is right for you.

Living with this condition

Living with a heart condition means being aware of your body and adjusting your pace. Listen to your energy levels, take breaks when needed, and keep regular appointments with your care team. Many people live full, active lives with a heart condition when they look after themselves.

Lifestyle tips

• Build daily movement into your routine — a walk after meals is a great start
• Keep a consistent sleep schedule and aim for 7–8 hours of restful sleep
• Weigh yourself regularly if you have heart failure — sudden weight gain can signal fluid buildup
• Plan ahead for physical activity, especially in very hot or cold weather
• Carry a list of your medicines and conditions in case of emergency

Diet and exercise

Aim for a balanced plate: vegetables, fruits, whole grains, lean protein (like fish or poultry), and healthy fats (like olive oil or nuts). Cut down on salty foods, sugary drinks, and processed meats. For exercise, choose activities you enjoy, such as walking, swimming, or cycling. Start slowly and build up, but always follow your doctor’s advice about what is safe for you.

Mental health and emotional wellbeing

A heart condition can bring worry, low mood, or anxiety. It is normal to feel this way after a diagnosis. Talking to friends, family, or a counsellor can help. Relaxation techniques, hobbies, and gentle movement also lift your spirits. If you feel overwhelmed, ask your doctor for support or your local mental health services.

Prevention

You can’t change some risk factors like age or family history, but many heart problems can be prevented or delayed. Eating well, staying active, not smoking, managing stress, and controlling blood pressure, cholesterol, and diabetes make a huge difference.

Vaccines

Some infections, like flu or COVID-19, can make heart conditions worse. It is a good idea to keep up to date with recommended vaccinations, such as the annual flu shot. Ask your pharmacist or doctor what is recommended for you.

Screening programmes

Regular health checks are a simple way to catch problems early. Ask your doctor about having your blood pressure and cholesterol checked, especially if you are over 40 or have a family history of heart disease.

Complications

If left untreated

• High blood pressure and cholesterol can lead to narrowed arteries, raising the risk of a heart attack or stroke
• Heart failure, where the heart becomes too weak to pump blood effectively
• Abnormal heart rhythms (arrhythmias) that can be life-threatening if not managed
• Peripheral artery disease, causing pain and poor circulation in the legs
• Kidney damage from reduced blood flow over time

Long-term outlook

The outlook for people with heart conditions is far better than it used to be. With modern treatment and a heart-healthy lifestyle, many people manage their condition well for decades. Every positive change you make helps your heart — even small steps add up.
