Thiazolidinediones and heart failure

From the Science Daily article:

A class of oral drugs used to treat type 2 diabetes may make heart failure worse, according to an editorial published online in Heart Wednesday by two Wake Forest University School of Medicine faculty members.

"We strongly recommend restrictions in the use of thiazolidinediones (the class of drugs) and question the rationale for leaving rosiglitazone on the market," write Sonal Singh, M.D., M.P.H., assistant professor of internal medicine, and Curt D. Furberg, M.D., Ph.D., professor of public health sciences. Rosiglitazone and pioglitazone are the two major thiazolidinediones.

Singh said in an interview, "Safer, cheaper and more effective treatment alternatives are available that do not carry these negative cardiovascular risks in patients with diabetes. The rationale for the use of the thiazolidinediones is unclear."
