As a common cardiovascular examination method, coronary angiography is widely used in the diagnosis of heart diseases. However, despite its importance in the medical field, there are certain risks associated with coronary angiography.
1. Coronary angiography may trigger allergic reactions
Contrast is an essential part of coronary angiography to improve the visibility of blood vessels and help doctors accurately diagnose cardiac lesions.
However, the iodine component of the contrast medium may trigger allergic reactions, especially in those who are allergic to iodine. Symptoms of an allergic reaction may include**itching, shortness of breath, facial swelling, etc., and in severe cases, it may even lead to shock.
2. Coronary angiography may cause damage to blood vessels
Coronary angiography is performed by inserting a catheter into the patient's blood vessels, a process that itself can cause some damage to the blood vessels.
Although doctors try to minimize damage during the procedure, there are still certain risks. Vascular damage can lead to complications such as bleeding, thrombosis, and in severe cases, it can even be life-threatening.
Therefore, coronary angiography needs to be performed with caution in patients with more severe vascular disease.
3. Coronary angiography may cause radiation damage
Coronary angiography requires the use of X-rays to look at blood vessels, which are inherently radioactive. Prolonged exposure to X-rays can cause damage to human tissues, especially for pregnant women and children, whose bodies are more sensitive. Therefore, coronary angiography requires special caution for pregnant women and children.
Fourth, the doctor also reminded that there are four types of people who need to be cautiousTry a coronary angiography
1. Older patients
They are relatively weak in their physical function and less tolerant of surgery.
2. Patients with severe renal impairment
Because coronary angiography requires the use of contrast agents, patients with renal insufficiency may not be able to effectively exclude contrast agents, thus increasing the burden on the kidneys.
3. Patients with severe heart failure
This is because coronary angiography requires a certain load on the patient, and patients with heart failure may not be able to withstand this load.
4. Patients with severe bleeding tendency
Because coronary angiography may cause vascular damage and bleeding, patients with bleeding tendencies may not be able to control bleeding effectively.
Summary: Although coronary angiography plays an important role in the diagnosis and development of heart disease, there are also certain risks and doctors remind that coronary angiography may cause allergic reactions, vascular damage and radiation damage, so there are four types of people who need to be cautious in trying.
