Diagnosis
Doctors use your medical history, a physical exam, and simple checks to estimate your risk of heart disease.
Tests that may be done
- Blood pressure measurement
- Blood tests for cholesterol and blood sugar
- Electrocardiogram (ECG)
- Risk score calculators
What to expect at your appointment
A doctor or nurse may ask about your diet, activity, smoking history, and family background. It usually takes place in a clinic and is painless.
Treatment
Treatment for heart disease depends on the underlying causes. The first step is usually lifestyle change, and medicines may be added if needed.
Self-care at home
- Eat a balanced diet with plenty of vegetables and whole grains
- Move more: aim for at least 150 minutes of moderate activity a week
- Quit smoking and avoid secondhand smoke
- Limit alcohol
- Manage stress with relaxation or talking therapy
Medical treatments
Depending on your condition, a doctor may prescribe medicines to lower blood pressure, reduce cholesterol, prevent blood clots, or help the heart pump more easily. These are always chosen in consultation with your healthcare team.
When is surgery considered?
In some cases, procedures such as angioplasty (opening a narrowed artery) or bypass surgery may be needed. Your specialist will explain the options clearly.
Living with this condition
Living well with heart concerns means taking your medicines as prescribed, keeping appointments, and making healthy choices one day at a time.
Lifestyle tips
- Take a short walk after meals
- Sit less throughout the day
- Get enough sleep
- Follow your doctor's advice about checking blood pressure at home
Diet and exercise
A heart-healthy diet is rich in fruits, vegetables, lean protein, and whole grains, and low in salt, saturated fat, and added sugar. Exercise can be broken into 10-minute chunks — every minute counts.
Mental health and emotional wellbeing
Heart problems can cause worry and low mood. It’s normal to feel anxious at times, but you don’t have to cope alone. Speak to your care team about how you’re feeling.
Prevention
Most heart disease is preventable. Up to 80% of early heart attacks and strokes can be avoided with healthy habits and good medical care.
Vaccines
Flu and pneumonia vaccines can help prevent infections that put extra strain on existing heart conditions. Ask your doctor if they are recommended for you.
Screening programmes
Regular blood pressure checks are the single most important screening test. Many pharmacies offer them free. You may also be eligible for a full heart risk check starting at age 40.
Complications
If left untreated
- Heart attack
- Stroke
- Heart failure
- Irregular heart rhythms
- Peripheral artery disease
Long-term outlook
With early action, many people live long, full lives. Even after a diagnosis, treatment and lifestyle changes can dramatically improve your health and quality of life.
