Rosiglitazone, pioglitazone increase risk of congestive heart failure but not cardiovascular death

A meta-analysis of seven clinical trials found that rosiglitazone and pioglitazone increased the risk of congestive heart failure in patients with type 2 diabetes or prediabetes. However, these drugs did not increase the risk of cardiovascular death. The authors recommend caution when prescribing TZDs to patients with cardiovascular di...
