Introduction:
Coronary artery is a medical examination method used to observe and assess the coronary artery of the heart. The coronary artery is the blood vessels that supply the heart and is responsible for the transport of oxygen and nutrients to the heart muscles. When the coronary artery is constricted or clogged, it causes heart failure and may cause serious diseases such as cardiac pain and myocardial infarction. Coronary artery can assist doctors in determining the condition of the coronary artery and provide important information for the treatment and prevention of heart disease.
I. The rationale and process of coronary photography
1. Rationale:
Coronary artery is a test method for the observation of coronary artery by injection of a film. Shadowing is a special substance that enhances the visibility of X-rays and allows the coronary artery to be visible on X-rays. By observing the distribution of the film-making agent in the coronary artery, doctors are able to understand the narrowness of the vessels, their pathological position and their properties.
2. Process:
Coronary artery is usually performed in the heart catheters of the hospital. The following are the basic steps of coronary cystography:
– Patients receive local anesthesia in order to alleviate the discomfort of the puncture.
– The doctor will establish an vascular route by piercing an artery (in the wrist) or a femoral artery (in the root of the thigh).
– Delivery of specially designed catheters along the artery to the aorta root, where the opening of the left or right coronary artery is found.
– Delivery of the catheter to the coronary artery on the surface of the heart and injection of the filming agent.
– The use of X-ray machines to photograph the heart and coronary artery and to observe the distribution of film-making agents.
II. Adaptive symptoms and importance of coronary cystography
Adaptation:
Coronary artery is applied to the following population groups:
– Patients suspected of coronary heart disease, such as frequent chest pains and cardiac pains.
– Persons diagnosed with coronary heart disease for further information.
– The condition of the coronary artery must be assessed for cases of heart infarction.
– A typical ischaemic hysteria, an EKG, a motor test, etc.
– Periodic review after coronary dysentery intervention or coronary artery bridging.
Importance:
Coronary artery is important for the diagnosis and treatment of heart disease:
– Determination of the narrowness and pathological position of the coronary artery to provide the basis for treatment.
– Assessing the extent and risks of coronary heart disease and guiding clinical decision-making.
– Detection of trends in coronary arterytic pathologies and prediction of the risk of heart events.
– Directing coronary artery intervention or coronary artery bridging.
III. SAFETY AND RISK OF CORPORATION
Security:
The coronary artery is a relatively safe test, but there are some risks.
(1) Complications associated with a film-making agent: Allergies of the film-making agent and possible rapid or late allergies. The kidney disease of the film maker was manifested in an increase of more than 25 per cent in blood acetic anhydride within 72 hours of injection. Shading agent cerebral disease, manifested in mental behavioral abnormalities, cognitive disorders, epilepsy, central nervous system symptoms, etc.
(2) Complications of the heart or blood vessels, such as cardiac arrest, vascular fracture, etc., may occur during coronary cystography, but less likely to occur.
(3) Operation-related complications:
– Damage to perforated areas and adjacent tissues, such as haematoma, arterythalamus, pseudoacoustic aneurysm, anthovenic fistula, postperitoneal haematoma, etc.
– The case of ischaemic haemorrhage, which may be the result of operations such as the production of a photocopying agent, a fuse, catheter propulsion, etc.
– Brain hemorrhage, brain infarction, heart infarction, heart disorder, epilepsy, etc.
– Bleeding has caused infarction in other areas.
– A puncture point infection.
– The film-making agent reverses the diarrhea to form a blood clot.
2. Risk evaluation:
The doctor conducts a risk assessment based on the patient ‘ s particular circumstances, and prior to the examination, the examination and evaluation to ensure that the patient ‘ s physical condition is suitable for coronary artery.
IV. Alternatives to coronary artery
CTA coronary artery:
The CTA coronary artery is a non-conceptive inspection method to observe the condition of the coronary artery through the use of multilayer spiral CT scans and photographic agents. The coronary artery CTA has some accuracy in assessing the narrowness and pathological position of the coronary artery, but it is not possible to provide detailed hemodynamic information and is not used to guide intervention or coronary artery bridging.
EKG and motion test:
The electrocardiograms and motor experiments are a non-involved check-up method that assesses the electrical activity of the heart and its reaction to motion, indirectly reflecting the condition of the coronary artery. However, there are limitations to these screening methods, which do not provide direct coronary artery images and which have limitations on the diagnosis and assessment of coronary heart disease.
Conclusions
Coronary artery is an important medical examination method that helps doctors to observe and assess the coronary artery of the heart. Through coronary pictography, doctors can determine the narrowness of the coronary artery, the location and nature of the disease and provide important information for the treatment and prevention of heart disease. Although there are certain risks associated with coronal artery, doctors conduct risk assessments based on the patient ‘ s circumstances and take appropriate precautions to ensure the safety of the examination. The coronary artery is an important diagnostic tool for people suspected of coronary heart disease or for people at risk of heart disease.
