While the heart pumps blood to the rest of the body, itself also needs blood. Two small arteries curve around and sit on the surface of the heart to bring blood back to the heart. Conditions which cause narrowing of the blood vessels such as high blood pressure (Hypertension) or high cholesterol (Hyper-cholesterolaemia) contribute to this condition.
This condition may be silent. The first symptom it produces may be your first heart attack. Therefore, regular screening is useful in picking this up.
In some people, the early symptoms may be angina. This is a feeling of tightness or pressure pain like a cramp over the front of the chest. This usually comes during some form of strenuous activities such as brisk walking, climbing up a flight of stairs or running. The feeling may radiate to the neck, jaw or down the arms. There may be accompanied by sweating or breathlessness.
If you have experienced any of these symptoms, there should not be any delay in seeing your doctor.
