Are Anti-Depressants Killing Heart Patients?

At a conference over the weekend, researchers announced that a study at Duke University of patients with coronary artery disease had a 55 percent higher risk of death than patients who took no anti-depressants. Researchers are at a loss to explain the finding--and hell I don't even have a guess--especially since it flies in the face of earlier studies showing that anti-depressants helped the same type of patients. In light of this finding, I wonder how many cardiologists are itching to make sure their patients take Prozac and how many law firms are lining up lawsuits.
