Most patients stay in the hospital for about four to seven days following transmyocardial revascularization (TMR) surgery. This includes several days under observation in the cardiac care unit and the remainder in a less critical care room. Even after discharge, minimal activity is recommended for several weeks during the healing process. A physician will work with individuals to assess their progress and to determine a safe range of activity.

The main goal of the procedure is to reduce the symptoms associated with coronary artery disease and increase patients’ ability to exercise. Other potential benefits from a TMR include:

The American Heart Association estimates that 80 to 90 percent of patients show significant improvement after a TMR. However, it may take time for these benefits to be fully enjoyed. Recognizable improvement after a TMR may not appear for three months or more, and maximum effectiveness may not be realized until as much as one year following the procedure. Research has shown that after one year TMR typically results in a higher quality of life for the patient. It has a very low rate of mortality or serious complication that requires hospitalization.

TMR is not a cure for coronary artery disease but simply a procedure that helps to relieve a major symptom – angina. Ongoing high-risk activities such as smoking will continue to worsen existing heart problems and reverse the benefits afforded by this surgery. Therefore, individuals who have undergone a TMR are strongly urged to follow a strict preventive program of diet and exercise, and smokers are strongly urged to quit smoking.
