Cardiovascular Diseases

The cardiovascular diseases are those diseases which are caused by disorders of heart and blood vessels. Coronary heart disease, cerebrovascular disease, hypertension, artery disease, rheumatic heart disease, congenital heart disease and failure of heart came under the category of cardiovascular diseases.

Most of the western countries face the high and increasing rate of cardiovascular diseases. More people are killed by this disease every year as compare to cancer. A survey concludes that diseases of the heart alone caused 30% of all deaths, with other diseases of the cardiovascular system causing substantial further death and disability. Every 2 out of 3 cardiac deaths occur without any diagnosis of cardiovascular disease.

After a survey it was conclude that this is the prime cause of death and disability in the United States and most European countries. A large histological study (PDAY) showed vascular injury accumulates from adolescence and makes primary prevention efforts necessary from childhood. An estimated concludes that17.5 million people died from cardiovascular disease in 2005 and this is about the 30 % of all global deaths. 7.6 million out of these were died due to heart attacks and 5.7 million were due to stroke.

Around 80% of these deaths occurred in developing or under developed countries as they have low and middle income. If not step is taken against it then according to an estimate, by 2015, 20 million people will die from cardiovascular disease every year and most of them will be from heart attacks and strokes.

Causes- The cause of cardiovascular disease is a blockage that prevents blood to go to the heart or to the brain. The most important and main cause of cardiovascular disease is build up of fatty deposits in the inner wall of blood vessels. In this particular condition, blood vessels become narrower and less broad and heart doesn’t receive the blood. In that case it results to failure of heart.
