Higher strength statins do not increase risk of kidney injury
- A higher strength of cholesterol-lowering drugs called statins did not increase the risk of kidney injury after heart attack.
- These findings may reassure doctors and patients of the safety of higher strength statins among heart attack survivors.
Statins have been shown to reduce the risk of a first or recurrent heart attack, but recent observational studies suggest that high doses may be linked to a higher incidence of kidney injury.
In this study, researchers analyzed data from two large clinical trials in which survivors were randomly assigned to receive either high- or low-dose statins. Higher strenght statins did not increase the risk of hospitalizations with kidney injury when compared to low-dose statins. In addition, concentrations of a blood protein, called creatinine, which reflects kidney function were comparable between the two groups during follow-up.
“These findings provide important reassurance to clinicians that the use of some high-potency statins will not increase the risk of kidney injury,” said Amy Sarma, M.D., M.H.S., the study’s lead author and a resident physician in internal medicine at Brigham and Women’s Hospital in Boston, Mass.
The study data were obtained from two trials with more than 4,000 participants each – the PROVE IT-TIMI 22, and the A-to-Z Trial.
