Living with heart

Overview

Heart disease is a general term for conditions that affect your heart and blood vessels. It includes problems like coronary artery disease (narrowed arteries), heart failure (weakened pumping), and arrhythmias (irregular heartbeats). Living with heart disease means managing these conditions over time to stay as healthy as possible.

Yes, heart disease is very common. It affects millions of people globally and is a leading cause of illness, but with modern treatment many people manage it successfully for years.

Heart disease can affect anyone, including children and adults. Your risk increases as you get older, and it is more common if you have high blood pressure, diabetes, smoke, or have a family history of heart problems.

Symptoms

Common symptoms

• Chest pain or discomfort (angina)
• Shortness of breath during activity or at rest
• Fatigue or feeling very tired
• Palpitations (feeling like your heart is racing or skipping beats)
• Swelling in the legs, ankles, or feet

Symptoms in children

• Difficulty feeding or poor weight gain
• Rapid breathing or trouble breathing
• Blue tint to the skin or lips
• Excessive sleepiness or irritability

Symptoms in older adults

• Shortness of breath even with mild activity
• Dizziness or confusion
• Swelling in the lower body
• Weakness or reduced ability to do daily tasks

Causes

Main causes

• Build-up of fatty plaque in the arteries (atherosclerosis)
• High blood pressure damaging the arteries over time
• Heart muscle weakness from past heart attack or infection
• Problems with the heart's electrical system leading to arrhythmias

Risk factors

• Smoking or exposure to second-hand smoke
• High cholesterol levels
• Diabetes or pre-diabetes
• Being overweight or obese
• Lack of physical activity
• Unhealthy diet high in salt, sugar, and unhealthy fats
• Family history of early heart disease
• Chronic stress or depression

When to see a doctor

See a doctor urgently if:

• If you have any of the emergency symptoms listed above, call emergency services immediately.
• If you have new chest pain, palpitations, or shortness of breath that does not improve with rest, seek urgent medical care.

Book a routine appointment if:

• If you have risk factors like high blood pressure, diabetes, or a strong family history, see your doctor for a heart health check even if you feel fine.
• If you have been diagnosed with heart disease, attend all your follow-up appointments and tests as scheduled.

Diagnosis

Your doctor will start by asking about your symptoms, medical history, and family history. They will listen to your heart and lungs, check your pulse and blood pressure, and feel for any swelling.

Tests that may be done

• Blood tests (check cholesterol, sugar, and heart enzymes)
• Electrocardiogram (ECG or EKG) – records the heart's electrical activity
• Echocardiogram (ultrasound of the heart) – shows heart structure and function
• Stress test – monitors your heart while you exercise or take medicine
• Holter monitor – a portable device that records your heart rhythm for 24–48 hours

What to expect at your appointment

Your doctor will explain the results of each test in plain language. They will discuss what your condition means for your daily life and work with you to create a treatment plan. You may need to see a heart specialist (cardiologist) for further care.

Treatment

Treatment for heart disease usually involves a combination of lifestyle changes, medications, and sometimes procedures or surgery. The goal is to control symptoms, prevent the condition from getting worse, and reduce the risk of complications.

Self-care at home

• Quit smoking and avoid second-hand smoke
• Eat a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins
• Get regular physical activity as advised by your doctor (like walking, swimming, or cycling)
• Manage stress with relaxation techniques, mindfulness, or hobbies
• Limit alcohol intake
• Monitor your weight and blood pressure at home if recommended

Medical treatments

Your doctor may prescribe medications to control blood pressure, lower cholesterol, prevent blood clots, reduce fluid buildup, or manage heart rhythm. Some people also take medications to help the heart pump more effectively. It is important to take all medications exactly as prescribed and discuss any side effects with your doctor.

When is surgery considered?

Sometimes surgery or procedures are needed, such as angioplasty (widening a narrowed artery with a balloon and stent) or bypass surgery (creating new routes for blood to flow around blockages). Pacemakers or implantable defibrillators may be used for rhythm problems. Your doctor will explain if any of these are right for you.

Living with this condition

Living with heart disease means taking care of yourself every day. Take your medications as prescribed, keep regular doctor appointments, and watch for changes in your symptoms. Learn to pace yourself – rest when you need to and stay active when you can. Keep a healthy routine and avoid things that make your condition worse, like smoking or too much salt.

Lifestyle tips

• Get enough sleep – aim for 7–9 hours per night
• Find healthy ways to cope with stress – talk to friends, practice deep breathing, or try gentle yoga
• Stay connected with family and friends – social support is very important
• Follow your care plan – attend cardiac rehabilitation if offered, as it provides structured exercise and education

Diet and exercise

A heart-healthy diet means eating plenty of vegetables, fruits, whole grains, and lean proteins like fish and poultry. Limit salt, sugar, and saturated fats (found in butter, fatty meats, and fried foods). Ask your doctor or a dietitian for a plan that works for you. For exercise, aim for at least 150 minutes of moderate activity per week, such as brisk walking. Start slowly and build up. Always check with your doctor before starting a new exercise routine.

Mental health and emotional wellbeing

Many people with heart disease feel anxious, depressed, or stressed about their health. This is normal and important to address. Talk to your doctor if you feel down or worried – they can offer support, counseling, or connect you with a mental health professional. Taking care of your emotional health is part of taking care of your heart.

Prevention

You can reduce your risk of developing heart disease or prevent it from getting worse. The key steps are: not smoking, eating a balanced diet, staying active, maintaining a healthy weight, managing blood pressure and cholesterol, controlling diabetes, and limiting alcohol. While some risk factors like family history cannot be changed, lifestyle makes a big difference.

Vaccines

People with heart disease should get the annual flu vaccine and the pneumococcal vaccine (to protect against pneumonia). Ask your doctor which vaccines are recommended for you.

Screening programmes

Regular health checks that measure blood pressure, cholesterol, and blood sugar can catch problems early. If you have risk factors, your doctor may recommend screening tests like an ECG or heart scan. Talk to your doctor about how often you should be screened.

Complications

If left untreated

• Heart attack (damage to the heart muscle)
• Stroke (damage to the brain from lack of blood flow)
• Heart failure (when the heart cannot pump enough blood)
• Arrhythmias that can cause fainting or sudden cardiac arrest

Long-term outlook

With proper care, most people with heart disease lead full, active lives. Treatments today are very effective, and many people manage their condition for decades. Listening to your body, following your treatment plan, and staying connected with your healthcare team are the best ways to stay well. You are not alone, and there is always hope.
