Low, not zero risk. When performed by an experienced operator in an experienced laboratory, cardiac catheterization and coronary angiography can be done with very low risk in most patients. The risks go up for very sick patients and for emergency procedures.
Yes. Not having coronary angiography when necessary is also dangerous. Every procedure has associated risks and benefits. Not doing a procedure has risks and benefits as well. Create a 2x2 square with risks / benefits at top and procedure / no procedure on the side. This will help you and your doctor identify and evaluate the options.
I am 45 years old. CT coronary angiography reveals short segment stenosis in mid circumflex. No stenosis in the rest of the coronary arteries with LVEF of 51%.how dangerous is this n how can this be treated. Kindly help?
Degree of stenosis? Is the stenosis in the mid circumflex of mild, moderate, or severe degree? Would you happen to know the TIMI score of that lesion? (It's a rather technical question, so you Cardiologist will know perhaps but you may not). If it is TIMI score of more than 3, causing symptoms or EKG changes, then it can be "reopened" using angioplasty or a stent. Talk to a Cardiologist about it. The EF is little low.
Evaluate your artery. The reason for angiography is to best evaluate the anatomy of your coronary arteries. The reasons that you may need to evaluate the anatomy of your arteries is to know why you have chest pain, why you have heart failure or irregular heart rhythm, or why you have an abnormal stress test. There are multiple reasons why an angiogram could be ordered. This should be discussed with your doctor.
Coronary angiography. When it is necessary to know the state of the coronary anatomy to make the appropriate therapeutic decision for a patient, the patient needs a coronary angiogram. If that information is not needed or is superfluous then the patient doesn't need the test.
CAD. Coronary artery disease (blockages in the coronary arteries).
Artery blockages. Usually, angiography is done to look for problems in blood supply to the heart. Blockage in the coronary arteries could lead to a heart attack. If a blockage is found, treatment such as angioplasty, stent placement, or even surgery for coronary artery bypass could be recommended. Symptoms such as chest pain (angina) on exertion usually call for a stress test, and maybe angiography.
Disease detection. This is a techniques of dye introduction, usually through a catheter, into the major heart vessels to detect pathology. Your life can be changed by early intervention to prevent serious cardiac events and the introduction of protective measures such as stents as well as lifestyle modification if pathology is starting or is present.
There are different. There are different dyes most are iodine based.
Angiography. We do angiography when it is important to see the patient's arteries. If it is important to visualize a patient's coronary arteries we do coronary angiography. The clinical situation usually dictates whether the need is present.
