Coronary heart disease is a common cardiovascular disease, and its incidence is increasing with people's lifestyle changes. Coronary angiography is an important method for diagnosing coronary heart disease, which can help doctors accurately understand the patient's condition and provide an important basis for treatment. This article will introduce you to the whole process of coronary angiography to help you better understand this diagnostic method.
1. What is coronary angiography?
Coronary angiography is an interventional diagnostic method that uses X-ray imaging to observe the coronary arteries by injecting a contrast agent into the patient's coronary arteries to determine whether there is a cardiovascular disease such as coronary heart disease. Coronary angiography is a safe and effective diagnostic method, which can help doctors accurately understand the patient's condition and provide an important basis for treatment.
2. Indications for coronary angiography
Coronary angiography is an important diagnostic method that is indicated in the following situations:
1. Patients suspected of coronary heart disease: such as chest pain, palpitations, shortness of breath and other symptoms.
2. Patients after myocardial infarction: Coronary angiography can help doctors understand the patient's coronary artery condition and provide a basis for treatment.
3. Patients before cardiac surgery: Coronary angiography can help doctors understand the patient's coronary artery condition and provide a basis for surgery.
3. Procedures for coronary angiography
1. Preparation: Patients need to have blood tests, electrocardiograms, etc. in advance to ensure that they are in good physical condition and can undergo coronary angiography.
2. Anesthesia: Coronary angiography requires local anesthesia to reduce the pain sensation of the patient.
3. Intubation: The doctor will insert a catheter into the patient's arm or leg and inject a contrast agent into the patient's coronary artery through the catheter.
4. Angiography: The doctor will use X-ray photography technology to observe the patient's coronary arteries to determine whether there are cardiovascular diseases such as coronary heart disease.
5. End: After the coronary angiography, the doctor will remove the catheter, and the patient needs to observe and rest to ensure that the body is in good condition.
4. Precautions for coronary angiography
1. Coronary angiography is an interventional diagnostic method, which requires local anesthesia, and patients need to inform the doctor in advance of their allergy history and drug use.
2. Coronary angiography requires X-rays, and patients need to be careful to avoid overexposure to reduce the impact of radiation on the body.
3. After coronary angiography, the patient needs to be observed and rested to ensure that he or she is in good physical condition.
5. Summary
Coronary angiography is an important method for diagnosing coronary heart disease, which can help doctors accurately understand the patient's condition and provide an important basis for treatment. Before performing coronary angiography, patients need to make preparations, precautions, etc., to ensure the accuracy and safety of diagnosis. #头条创作挑战赛#
