Diagnosis
Your doctor will ask about your symptoms and medical history, and do a physical exam. They may recommend tests to check your heart health.
Tests that may be done
- Blood pressure check
- Blood tests for cholesterol and blood sugar
- Electrocardiogram (ECG) – records your heart's electrical activity
- Echocardiogram – ultrasound of your heart
- Stress test – checks how your heart works during exercise
What to expect at your appointment
These tests are usually painless and done in a doctor's office or clinic. Your doctor will explain the results and what they mean for you.
Treatment
Treatment for heart problems depends on the specific condition. It often includes lifestyle changes and sometimes medications. Your doctor will create a plan that's right for you.
Self-care at home
- Eat a heart-healthy diet low in saturated fat, salt, and sugar.
- Get at least 150 minutes of moderate activity each week.
- Quit smoking and avoid secondhand smoke.
- Limit alcohol to recommended amounts.
- Manage stress with relaxation techniques like deep breathing.
- Take any prescribed medications exactly as directed.
Medical treatments
Depending on your condition, your doctor may prescribe medications to lower blood pressure, reduce cholesterol, prevent blood clots, or control heart rhythm. Surgery, such as angioplasty or bypass, may be needed for blocked arteries.
When is surgery considered?
Surgery might be recommended if lifestyle changes and medications are not enough, or if you have severe blockages in your arteries.
Living with this condition
Living with heart disease means making heart-healthy choices every day. It's important to follow your treatment plan, monitor your symptoms, and stay connected with your healthcare team.

- Stay physically active within your limits.
- Get enough sleep and manage stress.
Diet and exercise
A heart-healthy diet includes plenty of fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit processed foods, salt, and sugary drinks. Exercise, like walking or swimming, can strengthen your heart and improve circulation. Always check with your doctor before starting a new exercise routine.
Mental health and emotional wellbeing
Living with a heart condition can be stressful and may cause anxiety or depression. It's important to talk about your feelings with your doctor or a counselor. Support from family and friends can also help.
Prevention
Many heart problems can be prevented or delayed by adopting a healthy lifestyle. Even small changes can make a big difference.
Vaccines
Getting vaccinated against flu and pneumonia can help prevent infections that could strain your heart.
Screening programmes
Regular check-ups that include blood pressure and cholesterol checks can catch problems early. Talk to your doctor about when you should be screened based on your age and risk factors.
