How to diagnose angina pectoris

To confirm angina pectoris, medical history collection, physical examination, ECG examination, exercise stress test, cardiac ultrasound examination, coronary angiography and other examinations, such as radionuclide myocardial perfusion imaging, CT coronary angiography, etc. To confirm angina pectoris, the following examinations are required: 1. Medical history collection: The doctor will ask the patient's symptoms, frequency of attacks, incentives, etc. to understand the development of the disease. 2. Physical examination: including measurement of blood pressure, heart rate, rhythm, etc., auscultation of the heart, and observation of skin and mucous membranes. 3. ECG examination: This is one of the most common ways to diagnose angina pectoris. It records the electrical activity of the heart and helps doctors find signs of myocardial ischaemia.4. Exercise stress test: By putting the patient through exercise, increasing the stress on the heart and observing changes in the electrocardiogram, to assess heart function and the presence of myocardial ischaemia.5. Cardiac ultrasound examination: It can assess the structure and function of the heart, including systolic and diastolic function of the ventricles and movement of the myocardium. 6. Coronary angiography: This is an invasive examination method that uses a catheter inserted into the coronary artery and contrast medium injected to observe the degree of stenosis and blood flow in the coronary artery to help diagnose angina.7. Other examinations: Such as radionuclide myocardial perfusion imaging, CT coronary artery imaging, etc., can also be used to diagnose angina pectoris. The above examination methods can help doctors to clearly diagnose angina pectoris, and determine the severity of the disease, so as to formulate the corresponding treatment plan. It should be noted that for some atypical angina patients, a comprehensive evaluation of multiple examination methods may be needed to ensure the accuracy of diagnosis. At the same time, patients should inform their doctors about their medical history and medication before the examination, so that doctors can make correct diagnosis and treatment decisions.
