Chronic Angina Program
The University of Chicago Medicine is offering innovative treatment options for people who suffer from chronic angina--a common, sometimes disabling, symptom of coronary artery disease. Angina is recurring chest pain or discomfort caused by reduced blood flow to the heart.
Traditionally, most people with severe angina find adequate relief with drug therapy, angioplasty, or coronary artery bypass graft surgery. However, a significant portion of people who undergo these FDA-approved and effective treatments still experience troubling chest pain. And, in some cases, people are not candidates for angioplasty, stents, or surgical intervention--leaving little hope for pain relief. Many people are told they have no further options to treat their ischemic heart disease. (Ischemic heart disease refers to heart problems caused by narrowed arteries that reduce the amount of oxygen-rich blood flow to heart muscle.)
University of Chicago physicians are challenging the "no option" notion, and advise that no person with severe coronary artery disease and chronic angina should be viewed as having exhausted all treatment options after consideration of traditional bypass and catheterization approaches. There are several investigational and FDA-approved treatments for people with angina. These options are especially beneficial for people who are not candidates for angioplasty or bypass surgery due to age, additional heart problems, or other health concerns.
Multidisciplinary Program Offers More Options
University of Chicago cardiologists have formed a unique, multidisciplinary program specifically designed to help people who have chronic angina that cannot be relieved by traditional treatment methods. The University of Chicago Chronic Angina Program brings together specialists from cardiology, anesthesiology (pain management), and cardiac surgery to provide focused and innovative ways to treat angina. These physician-scientists are also conducting research into new and better ways to treat chronic angina.
The University of Chicago Chronic Angina Program can offer a wide range of alternative methods to treat chronic ischemic heart disease. One option currently under investigation involves "angiogenesis," the formation of new blood-flow pathways. UChicago Medicine physicians are studying the use of gene therapy to trigger the creation or enlargement of blood vessels to the heart; thereby improving previously impaired blood flow. These substances are delivered directly into the arteries. If successful, this gene therapy treatment may either reduce or stop angina, and decrease the severity of heart disease.
Another method under study works to block the sensation of chest pain. This approach, called spinal stimulation, involves the implantation of a small device that sends low-voltage electrical stimulation to the spinal cord in interrupt pain fibers. Similar devices are currently used to treat patients with back and leg pain.
Transmyocardial Laser Revascularization
Cardiac Center heart surgeons are using lasers to reduce cardiac chest pain. Transmyocardial laser revascularization (TMR) is an FDA-approved surgical technique that uses lasers to create small holes in heart muscle. These laser "channels" may destroy nerve fibers that cause pain or they may stimulate new blood vessels to grow.
If left untreated, chronic angina can lead to an inactive lifestyle that may contribute to disease progression. New treatment techniques offer hope to patients who had little to no options for pain relief or treatment for their heart disease.
