There are many causes for the development of Ischaemic heart disease. Among them we can count: diabetes, cholesterol level, smoking, obesity, hypertension (high blood pressure), emotional stress, high-fat diet, lack of exercise, abnormal heart valve function, abnormal heart rhythm, genetic & hereditary factors (Ischaemic heart disease runs in the family). Some heart diseases such as congenital heart disease are present at birth.
For example people with a high blood level of cholesterol are inclined to develop ischemia. Males are more exposed to ischaemic heart disease, but women after the menopause are as exposed as men are.
The main cause of the ischaemic heart disease is the narrowing or the blockage of the coronary arteries that have a very important function that is to supply blood & oxygen to the heart muscle. Healthy arteries are clean, slick & smooth. Their wall is flexible & it can become larger when a bigger quantity of blood is required to pass through. When this wall is injured a disease called atherosclerosis occurs. There is more. This causes the deposit of fat,calcium & cholesterol from your blood in the arteries walls. There is more. The arteries become narrow & harden or, even worse, they can block resulting in deficient oxygenation & nutrient supply to the heart muscle.
Ussualy atherosclerosis is a disease that develops in time. It might start in the childhood & progress with age, but it is also possible to develop very rapidly on people with risk factors like smoking, diabetes, high blood pressure, high cholesterol level, obesity.
Recent studies suggest that a bacterium called Chlamydia pneumoniae might be also a cause for the narrowing of the coronary arteries but this is yet to be demonstrated.
If you’re aware that you have one of the risk factors above, you should seek medical help. The doctor will perform a test for coronary artery disease or other cardiovascular issues. Cardiovascular is a term that refers to the circulatory system ? heart, veins & arteries.
It’s advisable that your doctor checks your risk for heart disease at least once a year by checking your cholesterol & blood pressure levels & asking whether you smoke or have a family history of heart disease. Also he can check your urine for protein, because this represents another risk factor for heart disease.
