Heart Diseases and there Symptoms

Heart diseases known as cardiovascular diseases are common in older people having problems in the main organ (heart) or the blood vessels. In America only, there are about 61 million people that have developed a form of it. There are varieties of diseases associated with heart attack like high blood pressure, hardening of arteries, pain in the chest and strokes.

At the centre of the body, the most important job is done by the heart that is the pumping of the blood in the vessels. The blood is the carrier of the oxygenated and deoxygenated blood. The cardiovascular diseases occur when the heart and the associated vessels do not work in the way they ought to be.
Arteriosclerosis is the hardening of the blood arteries which decreases its flexibility. Atherosclerosis occurs when there is a blockage due to the accumulation of cholesterol that makes the arteries thin and less blood flows across them. This blockage is also known as Plaque. Angina is the pain in the chest when the heart is unable to get the enough blood.

Heart attack is due to the blockages that cuts the flow of the blood to any part of the heart. When there is a clot in the blood vessel or it bursts and part of the brain is unable to get the adequate blood supply, this is a condition of stroke.

Heart diseases are not contagious and not something like the catching of the cold or flu. There are certain risk factors that increase the chances of heart diseases in the patients. Some of these are the age and the heart problems in the family, a person can't control them. But there are few risk factors which are controllable like smoking, blood pressure, over weight problems and lack of exercising that increases the chances of heart attack.
