Coronary Heart Disease
Coronary heart disease (CHD) is a major cause of death both in the UK and worldwide. CHD is sometimes called ischaemic heart disease.
Symptoms of CHD
The main symptoms of CHD are:
angina (chest pain)
However, not everyone has the same symptoms and some people may not have any before CHD is diagnosed.
Causes of coronary heart disease
Coronary heart disease is the term that describes what happens when your heart's blood supply is blocked or interrupted by a build-up of fatty substances in the coronary arteries.
Over time, the walls of your arteries can become furred up with fatty deposits. This process is known as atherosclerosis and the fatty deposits are called atheroma.
Atherosclerosis can be caused by lifestyle factors and other conditions, such as:
high blood pressure (hypertension)
Diagnosing coronary heart disease
If your doctor feels you're at risk of CHD, they may carry out a risk assessment. This involves asking about your medical and family history, your lifestyle and taking a blood test.
Further tests may be needed to confirm a diagnosis of CHD, including:
a treadmill test
a radionuclide scan
a CT scan
an MRI scan
a coronary angiography
Treating coronary heart disease
Coronary heart disease can't be cured but treatment can help manage the symptoms and reduce the chances of problems such as heart attacks.
Treatment can include:
lifestyle changes, such as regular exercise and stopping smoking
angioplasty - using balloons and stents to treat narrow heart arteries
the effects of CHD
If you have a heart attack or have had angioplasty or heart surgery, it's possible to eventually resume a normal life.
Advice and support is available to help you deal with aspects of your life that may have been affected by CHD.
You can reduce your risk of getting CHD by making some simple lifestyle changes. These include:
eating a healthy, balanced diet
being physically active
giving up smoking
controlling blood cholesterol and sugar levels
Keeping your heart healthy will also have other health benefits, such as helping reduce your risk of stroke and dementia.
