Question: What other drugs may be used to treat heart failure?
Answer: Right now, we do not have any new approved medication to treat patients with heart failure. We do have some new drugs coming [down] the pipeline. There are some hormone therapy to stimulate red blood cells, because we learned that patients with heart failure are usually found to have anemia and these patients need some help. But this is not yet proven, it is still under research development. For acute patients, patients that have the compensated heart failure, there are a number of initiatives, but still we are looking for the best medication to treat those patients. One of the areas that has been looked at are ranolazine -- a medication that's also been used for treating patients with coronary artery disease.
