Coronary heart disease patients, often listen to the doctor said to do a variety of tests, but because some of the tests on the expensive side, the patient due to economic and other reasons will not want to do, or doubt whether it is necessary to do this test? The following side to introduce some common sense things. Generally speaking, the routine tests for coronary heart disease include: electrocardiogram (general electrocardiogram, dynamic electrocardiogram), cardiac ultrasound, blood lipids, blood glucose, liver function, renal function; and if problems are detected, further tests include: coronary CT, coronary angiography. Since the latter two tests are more expensive, many patients are not willing to do them. However, I believe that if the condition requires it, it should be done. For example, if the condition is recurrent and there is high blood pressure or diabetes; if there is a family history of sudden death; or if the condition has been treated by many parties and the effect is not good. So what do coronary CT and coronary angiography have in common and what are the differences? Coronary CT: It is simple, convenient, fast, and costs little (around 1800 dollars in our hospital), and can be done on an outpatient basis. It can clearly show the shape of the coronary artery, with or without stenosis and plaque. Coronary angiography: requires hospitalization, costs more than 3,000 yuan, more intuitive and clearer image of the coronary artery, can be examined at the same time for treatment such as stenting, acute infarction can be intracoronary direct thrombolysis and so on. So according to different age, condition, different doctor will give you different suggestions. Whether you choose CT or imaging, it will be clear whether you have coronary heart disease or not. This way the treatment will be very smooth and not delayed. It actually works out to be a great deal more cost-effective than if you were to go around all day seeking medical attention and spending a fortune. The key is to ensure the safety of your life, invariably prolong life!
