1, electrocardiogram: electrocardiogram is the earliest, most commonly used and most basic diagnostic method in the diagnosis of coronary heart disease, electrocardiogram is easy to use, inexpensive, easy to popularize, and when the patient’s condition changes, then it can be captured in a timely manner, and can be continuous dynamic observation and a variety of load test, in order to improve the diagnostic sensitivity. 2.Nuclide myocardial imaging: according to the history, ECG examination can not exclude angina pectoris can do this top examination. Nuclide myocardial imaging can show the ischemic area and clarify the location and extent of ischemia. Combined with exercise test and then imaging, the detection rate can be improved. 3.Coronary angiography: It is the “gold standard” for the diagnosis of coronary heart disease. It can clarify whether the coronary arteries are stenotic, the location, degree and extent of stenosis, etc., and can guide the measures to be taken for further treatment accordingly. At the same time, left ventriculography can evaluate the heart function. 4.Echocardiography:cardiac ultrasound can examine the heart morphology, ventricular wall motion and left ventricular function, and it is one of the most commonly used means of examination at present. 5.Cardiac enzymology examination: it is one of the important means for the diagnosis and differential diagnosis of acute myocardial infarction. Clinically, according to the sequence change of serum enzyme concentration and specific isoenzyme elevation and other positive enzymatic changes, acute myocardial infarction can be clearly diagnosed. In addition, blood lipids and blood glucose should be checked regularly, because coronary heart disease is generally caused by atherosclerosis, and atherosclerosis has a great relationship with hyperlipidemia and diabetes mellitus. These tests are widely used in clinical practice, there may be some patients who would like to know in advance what kind of test is suitable for their condition before consultation, you can consult with me by phone, according to your actual situation to give you the appropriate advice, applying for telephone counseling of patients with the appropriate test results are best uploaded to the Internet, I’ll look at it in advance, the call effect will also be better. The specific upload method can refer to “How to upload pictures”.
