What is the ISCHEMIA Study? 

  • An international comparative effectiveness study
  • The purpose of ISCHEMIA is to determine the best way to manage stable ischemic heart disease
  • Patients with moderate or severe ischemia on stress test imaging may be eligible for participation

If you are a physician and would like more information, please visit the For Physicians section. If you are a patient and would like to learn more about the ISCHEMIA study, please e-mail ischemia@nyumc.org 

Why is the ISCHEMIA Study Important?

Ischemic heart disease (IHD) is the leading cause of death and disability worldwide and affects 17,600,000 Americans, resulting in about 450,000 deaths in the United States annually. Globally, 7.2 million deaths are caused by IHD each year.

Medical therapy (medication and lifestyle changes) should always be used to treat IHD. Many doctors routinely use an invasive approach in addition to medical therapy to treat IHD; however, it is not known if this approach is better than medical therapy alone as the initial treatment of patients with stable ischemic heart disease (SIHD). ISCHEMIA is designed to find the answer. Click here to learn more about the ISCHEMIA study.
