controversy about what works to prevent contrast-induced nephropathy

There's still a lot of controversy about what works to prevent contrast-induced nephropathy.

This nephropathy can be associated with longer hospital stays and increased mortality. In addition, about 1 in 3 patients who have it will have persistent worsening kidney function.

Continue to use preventive measures, especially for those with risk factors...older age, kidney disease, diabetes, heart failure, or hypertension.
