In another thread here, I mentioned the use of EECP, or Enhanced External Counterpulsation. This was recently mentioned at a Dr.'s appt. that I had recently re my angina. This is a procedure that can help people with continous angina, and I was told that I may be a candidate, unless the current medications help me.
There are a large, increasing number of patients who have persistent anginal symptoms, who have exhausted the standard treatments for revascularization and remain severely restricted. Enhanced External Counterpulsation (EECP) may stimulate the openings or formation of collaterals (small branches of blood vessels) to create a natural bypass around narrowed or blocked arteries.
To see more explanation of this procedure, please see the following...Teri
