In general, cardiovascular diseases are understood to be circulatory disorders of the arteries, i.e. the vessels that supply the body's organs with blood. Circulatory disorders of the heart (coronary heart disease, heart attack) and brain (stroke) are the most common causes of death in Germany. But it is not only the heart and brain that are affected by arteriosclerosis, but the entire vascular system, which is about 100,000 kilometers long. Particularly in the legs (shop window disease), the eyes or the kidneys, circulatory disorders cause serious illnesses with a severe reduction in quality of life.
