Facts about the heart

Some Facts about the heart

v  The heart beats approximately 100,000 times each day.

v  About 7000 liters of blood flows through the heart.

v  Like other parts of the body, the heart receives its food through a system of arteries, known as coronaries.

v  The chances of a smoker suffering from a heart attack are three times more as compared to a non-smoker. On quitting, the risk is out to half in about a year’s time. After 10 years your odds nearly return to normal.

Coronary Arteries

Normal coronary arteries are similar to clear pipes and possess smooth linings. Therefore, the flow of blood through these arteries is smooth and free. Risk factors like high cholesterol, smoking, diabetes and high blood pressure can damage the lining of the arteries.

Heart attack

Heart attack occurs when there is a total blockage of a coronary artery. Heart attack, unlike angina lasts longer. It is a pain of more intensity and is not relieved by rest or medication. Heart attack causes damage to the heart muscle, which is permanent.

Medication often relieves the symptoms of angina. Different types of drugs are available, but they all have one purpose- to reduce the contraction and rate of the heart. All medications have possible side effects, which if needed can be discussed with your doctor.
