In this case, make sure your surgeon has a low complication rate for people without symptoms. It should be less than three percent, and preferably much lower. You can find more information at www.consumerreports.org/ health/doctors-hospitals/hospital-ratings.htm.
The tests aren't needed before surgery.
A variety of imaging tests may be used to examine the heart. Echocardiography uses sound waves to take pictures of the heart. Nuclear cardiology tests use a small amount of radioactive material to show the blood flow to the heart. And a cardiac CT scan uses x-rays to look at the blood vessels and structure of the heart.
These tests can show if you're at risk of having a heart attack or another serious problem during surgery. The tests may show that you need special care during or after surgery. Or you may need to delay surgery until the problem is treated, or have a different kind of surgery.
But if you have minor surgery, the risk of heart problems is very low. Minor surgeries include any "same-day" surgery, such as breast biopsy, eye, or skin surgery. There isn't much more doctors can do to lower the risk. And having a heart-imaging test is not likely to lower your risk.
In fact, even major surgery is safe for most healthy people who feel well, are moderately physically active and do not have symptoms of heart disease. In this case, usually all you need before surgery is a careful medical history and physical exam.
Heart imaging tests have risks.
The tests are usually safe, and some can be done with little or no radiation. But if your risk of having a heart problem is low, the tests can produce false-positive results. This can cause anxiety and lead to more tests and delay of your surgery. For example, you might have a follow-up coronary angiography, which exposes you to more risks and radiation. The risks are low, but exposure to radiation adds up over your lifetime, so it's best to avoid x-rays whenever you can.
Imaging tests can cost a lot.
An imaging stress tests costs $500 to $2,000. A cardiac CT scan costs $500 to $600. A follow-up coronary angiography costs about $5,000. So the tests should only be used when the results would change the way your surgery is done.
