Which condition would NOT be indicated as a complication from contrast agents used in coronary arteriography?

In evaluating the use of contrast agents during coronary arteriography, it is essential to recognize the common complications that can arise from their administration. The condition that would not be indicated as a complication from contrast agents, specifically in the context of coronary arteriography, is lower gastrointestinal bleeding.

Contrast agents can lead to several adverse effects, primarily due to their impact on renal function and potential for allergic reactions. In particular, renal failure is a well-documented complication, especially in patients with pre-existing kidney issues or those who are dehydrated. Myocardial infarction can also occur, although it is less frequent, particularly in patients with pre-existing coronary artery disease. Pulmonary embolism can be a risk if thrombus formation is associated with the procedure, especially given the potential for turbulence and vascular injury during catheter manipulation.

Lower gastrointestinal bleeding, however, is rarely related to the use of contrast agents in coronary arteriography. It generally pertains to other conditions such as bowel ischemia or coagulopathy and is not a direct consequence of contrast agent use. Therefore, this condition stands out as the one not linked to complications arising from contrast exposure in this specific cardiovascular setting.
