Introduction
Heart is that organ of the body that pumps blood to all other parts of the body, thus ensuring their apt functioning. So the function of heart is not merely beating; it is the life saving organ of human body. To perform its function, heart needs plentiful and nutritious supply of blood too. This blood comes through the coronary arteries located near aorta. If the arteries get blocked due to the deposition of cholesterol, it causes cardiovascular system diseases. The cholesterol hampers the flow of blood and when the clot formed gets ruptured, it causes cardiovascular system diseases like heart attack. But these diseases are not only restricted to the heart. It also covers the entire blood vessel system of the body and any malfunctioning results in these diseases as well.

Cardiovascular system diseases are those which occur due to the disruption of blood vessels and malfunctioning of heart. The most common among these is the high blood pressure rate that engulfs millions of people today. This often leads to increase in heart beat and head aches. Heart diseases are also very frequent among people aged between 20 and 40. These diseases are due to the presence of cholesterol in the arteries of heart and the blockage of the smooth flow of blood through them. This causes the heart to put in extra effort to pump blood to all organs of the body. This reduced blood flow results in strokes and heart attacks. Another very common illness is the arthrosclerosis that occur when the arteries of the body get hardened. The pain of Angina has also long been causing trouble to a number of people and is thus classified as a major disease. When it comes to fatality, congestive heart failure is considered very common. It is one of the most dominant causes of death in many countries.
