Key result
Low osmolal contrast agents are superior to high osmolal contrast agents, but high osmolal agents can be used safely and effectively for cardiac angiography in mild or moderate heart disease.
Why the study?
Does the use of low osmolal contrast agents compared to high osmolal contrast agents improve safety in patients undergoing cardiac angiography?
Does the use of low osmolal contrast agents compared to high osmolal contrast agents improve safety in patients undergoing cardiac angiography?
While low osmolal contrast agents may offer added safety in high-risk patients, high osmolal contrast agents that do not bind calcium are safe and effective for patients with mild to moderate heart disease, offering a cost-effective alternative.

Supports high-osmolal agents in mild-moderate disease; leaves open randomized confirmation of safety versus low-osmolal options.
Matthai et al. (1991) conducted a review in Mild or moderately severe heart disease requiring cardiac angiography. Low osmolal contrast agents (LOCA) vs. High osmolal contrast agents (HOCA) was evaluated. Low osmolal contrast agents are superior to high osmolal contrast agents, but high osmolal agents can be used safely and effectively for cardiac angiography in mild or moderate heart disease.
