The efficacy of coronary angiography

Coronary angiography is a key diagnostic tool for coronary heart disease, which can visually display the stenosis or obstruction of coronary arteries and provide accurate basis for treatment. It injects contrast agent into the coronary arteries and uses X-ray imaging technology to clearly present the vascular morphology, helping doctors determine the degree and location of lesions. The main efficacy of coronary angiography lies in its diagnostic accuracy. It can directly observe the stenosis, obstruction, or malformation of coronary arteries and is currently the "gold standard" for diagnosing coronary heart disease. For patients suspected of having angina pectoris, myocardial infarction, or unexplained chest pain, imaging examination can clarify the cause and exclude other possibilities. At the same time, it can also evaluate cardiac function and provide important references for subsequent treatment. Coronary angiography plays an important role in treatment planning. Based on the examination results, doctors can decide whether intervention therapy is needed, such as stent implantation or coronary artery bypass surgery. For patients diagnosed with coronary heart disease, angiography can evaluate the progression of the disease, guide drug adjustments or optimize surgical plans. It can also help assess the recovery of blood vessels after myocardial infarction and evaluate treatment effectiveness.

3. Coronary angiography has high safety, but indications and contraindications still need to be noted. Before the examination, it is necessary to evaluate the patient's heart function, kidney function, and allergy history to avoid complications related to contrast agents. Transient arrhythmia or blood pressure fluctuations may occur during the examination process, but usually do not cause serious damage. Close observation of the puncture site is necessary after surgery to prevent bleeding or hematoma. Coronary angiography, as an important tool for the diagnosis and treatment of coronary heart disease, has irreplaceable value. For patients suspected or diagnosed with coronary heart disease, timely imaging examination can help clarify the condition and develop personalized treatment plans. At the same time, doctors should weigh the pros and cons of examinations based on the specific situation of patients to ensure medical safety. For high-risk populations, regular physical examinations and early screening are equally important in preventing disease progression and reducing the risk of cardiovascular events.
