Coronary Heart Disease
Coronary heart disease is a long-term condition that affects many people around the world.
This disease is a disorder of the heart muscle caused by problems with the coronary arteries. The arteries supply their heart with oxygen- and nutrient- rich blood. Often plaque builds up inside the coronary arteries, the consequence is that the vessels are narrowed and not enough oxygen-rich blood can be transported in the heart muscle. These phenomena are called atherosclerosis of coronary arteries.
After a while the minor supply of oxygen-rich blood causes damage of the heart muscle.
There are various symptoms of a coronary heart disease like ...view middle of the document...
With this method you can see if the patient has under normal life condition (work, leisure, sport, sleep) angina pectoris attacks or other abnormality in the ECG.
An angiogram is a roentgen graphic examination of blood vessels after injection of a radiopaque contrast medium. A long thin, plastic tube is inserted into a blood vessel in the groin area (femoral artery) or in the arm (brachial artery). On the radiographs it is possible to see if there are vessels narrowed. This test is absolutely necessary for the cardiologist to decide the later treatment like surgery or just medication.
Stress echocardiography is a test that uses ultrasound imaging to show how the heart muscle respond to stress. First the echocardiography will be done during rest, than the test will be done again after exercise or getting medication to reach the target heart rate. Now you can compare the movement of the ventricular walls during rest and stress. The ultrasound monitor will reveal any part of the heart that get not enough oxygen-rich blood caused by narrowed arteries.
Myocardial perfusion scintigraphy
A slightly radioactive substance (normally thallium) will be injected into a vein. A special camera can see the blood flow in the heart. Well- perfused areas in the heart muscle accumulate the radioactivity, poor circulation areas appearing pale. This test will be done also normally twice, without stress and under stress.
Positron emission tomography (PET)
The PET is a special technique that produces three-dimensional images. Thus you can use it for coronary heart disease to show, which areas of the heart muscle are still active and which is damaged because of minor oxygen-rich blood perfusion.
This test is very costly and only available in large medical centres.
Coronary Heart Disease Treatment
If you have coronary heart disease and donâ€™t want that it becomes worse, it is very important to take care of a healthy life style. This means lower the blood cholesterol with special diet, do regular exercise, no smoking, moderate consume of alcohol, control high blood pressure and diabetes.
If al these measures do not help and the disease progresses, other therapeutic ways must be seized.
Depending from the stage of the disease, different treatment methods are necessary. For easier stages of CAD, drug therapy is common. Various medication which are reducing the oxygen consumption are used to improve the heart work and as a consequence to reduce the frequency of seizures and attacks. These different drugs are used single or in combination.
One of the most known is Acetylsalicylic acid (ASA) that inhibits the thrombocytes, which are important for the blood clotting. Many people taking as prophylaxes against heart attack and stroke. With taking ASA long-term the risk of bleeding increases.
