Danish Survey Finds Clopidogrel Less Effective in Diabetics
Larry Husten, PHD
A large nationwide survey of MI survivors in Denmark provides new information about the efficacy of antiplatelet therapy with clopdiogrel in patients with diabetes.

As expected, diabetics had a worse outcome than nondiabetics: the composite […]

Novel Antiplatelet Agent Reduces CV Events But Increases Bleeding
Larry Husten, PHD
Vorapaxar, the novel antiplatelet agent from Merck, appears to effectively reduce cardiovascular death and ischemic events in patients with MI, ischemic stroke, or peripheral vascular disease, but its potential utility is clouded by bleeding complications, including intracranial hemorrhage. Results from the TRA 2P-TIMI 50 (Thrombin Receptor Antagonist in Secondary Prevention of Atherothrombotic Ischemic Events) trial were presented […]

However, the efficacy of antiplatelet therapy in CKD has not been examined, despite the fact that people with CKD are more likely to die from nonatherosclerotic conditions and are more likely to […]

Study Finds No Evidence for Clopidogrel-Omeprazole Interaction
Sanjay Kaul, MD and Larry Husten, PHD
A large clinical trial has found no evidence that omeprazole interferes with the cardiovascular efficacy of clopidogrel. COGENT (Clopidogrel and the Optimization of Gastrointestinal Events Trial) randomized 3873 patients eligible for dual antiplatelet therapy to receive aspirin, clopidogrel, and either omeprazole or placebo. The COGENT investigators had planned to enroll 5000 patients, but the trial […]
