Heart Disease UK

A blockage in the heart's arteries may reduce or completely cut off the blood supply to a portion of the heart. This can cause a blood clot to form and totally stop blood flow in a coronary artery, resulting in a heart attack (also called an acute myocardial infarction).
Irreversible injury to the heart muscle usually occurs if medical help is not received promptly. Unfortunately, it is common for people to dismiss heart attack symptoms.
Many medical experts say the body likely will send one or more of these warning signals of a heart attack.
The actual diagnosis of a heart attack must be made by a doctor who has studied the results of several tests. The doctor may:
Review the patient's complete medical history.
Give a physical examination.
Use an electrocardiogram (or EKG) to discover any abnormalities caused by damage to the heart.
Use a blood test to detect abnormal levels of certain enzymes in the bloodstream.

Heart disease is the leading cause of death. There are many factors which may put you in a high-risk group for heart disease. If you have a family history of heart disease, have been diagnosed with high cholesterol, or have high blood pressure, you may be at risk to develop heart disease. A heart scan can reveal even minor problems, which could not be detected by physical examination, EKG, or stress test, giving you the foresight to take the necessary steps to maintain your health.
The heart scan, captures detailed, cross-sectional images of your heart, revealing the presence of coronary artery calcification, a key factor in determining your risk of heart disease. The overall condition of your heart health is based on this "calcium scoring."
Since most people have no warning of an impending heart attack, a heart scan can give you the foresight to take the necessary steps to maintain your good health.
