For the common man, cardiovascular diseases and heart disease are same. However, medically, these two are slightly different involving different parts of the organ. While heart diseases implies diseases relating to the blood vessels and heart within the system, cardiovascular disease implies diseases of blood vessels such as capillaries, arteries and veins that are part of an individual’s entire body that even includes brain, legs and lungs.
The term cardiovascular system has been derived from two words -- cardio that means the heart, and vascular that means the blood vessels.
Heart diseases are again categorized into various types that involve the heart, such as angina, arrhythmia, valvular heart disease, and CAD or coronary heart disease. Heart disease can also be sometimes referred to as cardiac disease, but not as cardiovascular disease.
Heart is the main organ in our body that performs the function of pumping blood through the entire circulatory system of the body. The circulatory system is a network of various tubes in the form of arteries, veins and capillaries. There are two major organs which form the part of circulatory system -- the lungs and the heart. There are network of arteries and capillaries which carries oxygen rich blood from the heart and lungs to all parts of the body and there is a network of veins and capillaries whose function is to carry the oxygen deficient blood from all parts of the body back to the heart and lungs.
An illness of heart does not occur suddenly. The arteries that bring blood to the heart and brain can get blocked due to the development of fat cells all around the tubes which restrict the movement of blood. The build up of these fat cells are nothing but cholesterol. Due to deficient blood supply to heart and then subsequently to brain, blood clots occur and result in strokes.
