The cardiovascular system is complex and, as with anything, problems can occur. These problems could take place anywhere from the electrical system of the heart to the large or small blood vessels. When a problem occurs within the cardiovascular system, it is known as a cardiovascular disease.
There are over 60 different types of cardiovascular disease, all of which somehow affect the heart ("cardio") or blood vessels ("vascular"). Some cardiovascular diseases are common, such as coronary heart disease or stroke, while others are rare. Some cardiovascular conditions (congenital heart disease) are present at birth, while other cardiovascular diseases develop over many years.
