The study also showed that the medication was safe for patients with the condition.
A study found that older adults taking rosiglitazone had a 15% higher rate of death and 13% greater risk of heart failure compared to those taking pioglitazone. The authors highlight the need to consider all-cause mortality risk in elderly patients, as rosiglitazone's cardiovascular effects may be more pronounced.
Adults with severe heart failure see an average of 23 providers annually, while those with mild and moderate heart failure see 15.9 and 18.6 providers respectively.
