Plaque Formation : heart

Plaque Formation

Plaque is a fatty substance in the blood which often builds up in and around the smooth arterial muscles. Clot forming platelets can accumulate on this. Due to the formation of the plaque, blockage of the vessels starts, restricting the blood flow.

The atherosclerosis plaque can block a part or whole of the “affected” artery and “atherosclerosis” is the result. The partial blockage of oxygen rich blood to the heart often results in chest pain. When the blockage is total, it can result in a heart attack.

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.

Your Heart and its Arteries

The Heart

The heart lies in the center and more towards the left of the chest in an area called the mediastinum. As the heart is tilted slightly to the left you feel the beat of your heart on the left side at the apex. Here the beat is supposed to be the strongest.

The heart is about the size of a fist and weighs less than a pound. It is pinkish grey in color and is mainly made up of muscle called myocardium. It is hollow and divided into a left and a right side. Each side has two chambers, the one above is known as the atrium and the one below, ventricle.

                The heart pumps life-sustaining blood through the body. The right side of the heart supplies blood to the lungs, while the left, the stronger side, supplies blood to the rest of the body. Oxygen and glucose are supplied to the body. Carbon dioxide and waste gases collected in the blood are passed into the right atrium and via the right ventricle and pulmonary artery, are pumped out through the lungs. Blood from the lungs takes in oxygen which is breathed in by respiration. This blood goes to the left atrium and then to the left ventricle where it is pumped out from aorta to the rest of the body.
