Blood disorders affect one or more parts of the blood and prevent your blood from doing its job. They can be acute or chronic. Many blood disorders are inherited. Other causes include other diseases, side effects of medicines, and a lack of certain nutrients in your diet.
During the first eight months of 2012, statistics from the Norwegian Cardiovascular Disease Registry show that 10,500 people had an acute myocardial infarction and 9,000 had a stroke as the main diagnosis. This indicates the following annual statistics for heart attacks and strokes: • Heart disease: Approximately 15,000 people have an acute myocardial infarction each year. Half of these are under 74 years-old. In addition, there is an unknown number who have angina pectoris, heart failure or other forms of heart disease. • Stroke: Approximately 13,000 have a stroke every year. Half of these are under 76 years-old. A study from Nord-Trøndelag suggests that one in four strokes occurs in patients who have previously had a stroke (Ellekjær og Selmer, 2007). 4852 people died from ischaemic heart disease (including angina and myocardial infarction) in 2012. There were 3116 deaths due to stroke in the same year.
Depending on the disorder, treatment options can include growth factors to stimulate blood cell production, steroids or other drugs to suppress the immune system, and chemotherapy to destroy abnormal cells. Bleeding disorders like hemophilia may call for blood-component therapies, such as platelet transfusions or clotting factors; diseases that involve clotting might be treated with drugs that inhibit clot formation.
