Recently, Aunt Chen has been suffering from chest pain in the past few days, and came to Hanshou County People's Hospital for examination, and the cardiovascular physician said to do coronary angiography, which is sad Aunt Chen, what is coronary angiography? I have never heard of it, is this the same as other examinations? Is it traumatic? Is it dangerous? What are the sequelae of coronary angiography? What should I pay attention to?......?
Next, experts from the Department of Cardiovascular Medicine of Hanshou County People's Hospital will solve your doubts!
1. What is coronary angiography?
Coronary angiography, also known as coronary angiography, is a common and effective diagnostic method for diagnosing coronary atherosclerotic heart disease (coronary heart disease) and is the "gold standard" for diagnosing coronary heart disease.
Coronary angiography is to percutaneously puncture the contrast catheter into the radial artery of the upper limb or the femoral artery of the lower limb of the patient under local anesthesia, send it to the root of the ascending aorta along the direction of the arterial blood vessels, and inject contrast agent to visualize the coronary arteries of the heart, so as to judge the location, degree and scope of coronary artery obstructive lesions, etc., and provide a basis for the diagnosis and treatment of coronary heart disease.
2. Is coronary angiography dangerous?
Coronary angiography is a hurdle that many patients with coronary heart disease cannot avoid, although it is invasive, there are still certain risks.
But don't be nervous, as long as the patient communicates with the doctor before and after the imaging examination, and follows the professional arrangements and suggestions of the medical staff, the coronary angiography examination will be completed smoothly. The examination usually takes only about 30 minutes.
3. Who needs a coronary angiography?
1. Patients with chest pain symptoms, electrocardiogram showing myocardial ischemia, or positive stress exercise test, and clinical suspicion of coronary heart disease;
2. Patients with unexplained arrhythmia, cardiac insufficiency, and cardiac enlargement;
3. Have been diagnosed with coronary heart disease, in order to further understand the situation of coronary artery disease;
4. Patients with acute myocardial infarction requiring emergency revascularization;
5. Follow-up after coronary angiography interventional treatment;
6. Congenital heart disease, valvular heart disease and other major surgeries need to be performed before coronary angiography;
7. Asymptomatic but suspected coronary heart disease, engaged in high-risk occupations such as pilots, firefighters, drivers, athletes, or medical insurance needs.
4. Who is not suitable for coronary angiography?
1. Patients with severe renal insufficiency. Patients with renal insufficiency may have impaired excretion of contrast, which can worsen renal failure;
2. Patients with severe cardiac insufficiency. A large amount of contrast medium enters the human body in a short period of time, which will increase the burden on the heart and even induce acute heart failure;
3. Those who are allergic to iodine or contrast media;
4. Those who are suffering from infectious diseases and fever;
5. Those who have not yet controlled hyperthyroidism. Iodine in contrast can worsen hyperthyroidism;
6. Those with high risk of bleeding. Coronary angiography is anticoagulated with heparin, which may be at risk of major bleeding if there is trauma, intracerebral hemorrhage, gastrointestinal bleeding, or other coagulation disorders;
7. Those who have mental illness and cannot cooperate with doctors.
5. What preparations do I need to make before coronary angiography?
1. Relevant examinations should be completed before surgery;
2. The doctor should be informed of all the drugs currently taking before surgery;
3. Before the operation, loose clothes should be changed and all jewelry should be removed, which is conducive to the surgical operation;
4. Rest well before surgery, no need to be overly nervous;
5. Fasting for 1 hour before surgery, drinking plenty of water, and intravenous infusion for hydration to reduce the occurrence of organ damage.
6. Do I need to put a stent after coronary angiography?
Unconsistent.
Coronary angiography is only a test to confirm the diagnosis of coronary heart disease, while coronary artery stenting and coronary drug balloon dilation are interventional treatments to solve vascular stenosis.
The original guidelines required that 75% of patients with coronary artery stenosis ≥ and symptomatic coronary artery disease should be recommended for active stent therapy, and now there is a new study that even with stable angina, stent therapy is recommended when coronary artery stenosis ≥ 90%, but this is a modeled theory, and the specific clinical operation requires multi-factor joint evaluation to decide whether to intervene in the treatment.
Therefore, it is not possible to generalize that blood vessel stenosis requires stents, but to analyze specific problems.
7. Precautions after coronary angiography
1. After the examination, it is necessary to compress and stop the bleeding, determine the immobilization time according to the puncture site, and pay attention to the puncture wound.
2. After coronary angiography, in order to excrete the contrast agent from the body as soon as possible, patients should be encouraged to drink more water.
3. If you have palpitation, chest tightness, difficulty breathing and other discomfort after surgery, please inform the doctor in time.
