Surgical and Other Procedures for Coronary Artery Disease (CAD) and Angina
If you cannot control
Percutaneous Coronary Intervention (PCI)
A study compared PCI plus optimal medical therapy (intensive medications and lifestyle changes) to optimal medical therapy alone in stable heart patients. Researchers found that adding PCI to treatment did not reduce the risk of death, myocardial infarction, or other heart-related events.
Coronary Artery Bypass Graft (CABG)
During this operation, a blood vessel (vein) is taken from the leg or chest or wrist and grafted into a diseased artery, bypassing the blocked area. If more than one area is blocked, a bypass can be done for each area (leading to double, triple, or quadruple bypass). The blood can then go around the obstruction to supply the heart with enough blood carrying oxygen to relieve chest pain.
This surgery has typically been done with the patient on cardiopulmonary bypass (CPB), which immoblizes the heart and keeps it still. Newer methods utilize a "beating heart" procedure, whereby CPB is avoided and the surgery is performed with the heart still beating. While the results are encouraging, it is a relatively new procedure. Talk to your doctor about what options are available, and which one might be best for you.
An open CABG is considered major surgery, using
According to a review of 23 studies, patients who received CABG had more angina relief and less need for another, similar procedure than those who received percutaneous coronary intervention (PCI). PCI involves techniques using
Enhanced External Counterpulsation (EECP)
For patients who are not candidates for the revascularization procedures described above but with refractory chest pain, EECP can be utilized. This is a noninvasive procedure in which inflatable bags are wrapped around the legs (like a blood pressure cuff around the arm) and inflated and deflated in concert with the patient’s heart beat. The patient receives 35 one hour sessions over 7 weeks. This treatment has been shown to reduce the frequency of chest pain.
Studies are underway looking at gene therapy to help the heart grow new blood vessels. This is still an experimental procedure.
