How to detect heart failure

The diagnosis and evaluation of heart failure usually requires a combination of examination methods, including cardiac ultrasound, ECG, blood test, stress test, radionuclide ventriculography, cardiac magnetic resonance imaging, coronary angiography, etc. Doctors will develop personalized examination plans according to the patient's condition. Heart failure can be diagnosed and evaluated by various examination methods. The following are some common examinations: 1. Cardiac ultrasound: This is an important test to assess the structure and function of the heart. The ultrasound probe can measure the size of the heart, wall motion, valve function, etc., so as to determine whether the heart has systolic or diastolic dysfunction. 2. ECG: Record the electrical activity of the heart, which can detect arrhythmia, myocardial ischemia and other problems. 3. Blood test: include measurement of myocardial enzymes, BNP/NT-proBNP and other indicator. elevated myocardial enzymes indicate myocardial damage, BNP/NT-proBNP elevation is associated with that severity of heart failure. 4. stress test: such as exercise stress test or drug stress test, to assess cardiac functional reserve by increasing cardiac load. 5. radionuclide ventriculography: Cardiac magnetic resonance imaging (MRI): provides more detailed information about the structure and function of the heart and is helpful in diagnosing myocardial infarction, cardiomyopathy, etc. Coronary angiography: If heart failure is suspected to be caused by coronary artery disease, coronary angiography is required to evaluate the condition of the coronary arteries. It should be noted that the specific examination items will be selected according to the patient's symptoms, signs and other factors. The doctor will develop a personalized examination plan according to the patient's condition. In addition, for some special groups, such as elderly people, patients with other diseases or patients who are taking certain drugs, it is necessary to inform the doctor before the examination so that the doctor can evaluate whether certain examinations are appropriate or adjust the examination protocol. If you suspect that you or someone else has symptoms of heart failure, you should seek medical attention promptly. Your doctor will conduct a detailed examination and evaluation according to the specific situation, and formulate a corresponding treatment plan. Early diagnosis and treatment can help improve the prognosis of heart failure and improve the quality of life.
