Anesthesia can still be used if you have heart problems, but your team watches your heart and blood pressure very closely and chooses the plan based on your situation. Inhaled anesthetics can lower blood pressure in a dose-dependent way, mainly by lowering blood vessel resistance, and they can also reduce cardiac output, which is the amount of blood the heart pumps. Some agents, like sevoflurane, tend to have less effect on the heart and blood pressure than others.

For heart surgery, the anesthesiologist is part of your care before, during, and after the operation. They review your history and tests, explain the plan, and tell you which medicines to stop or continue in the days before surgery. During surgery, they use monitors for heart rhythm, blood pressure, oxygen, and sometimes ultrasound of the heart. They may also use special lines in a vein or artery to watch you more closely.

The exact anesthetic can be general anesthesia, regional anesthesia, or a mix, depending on the surgery and your heart condition. There is no single best approach for everyone. The goal is to keep your heart rate controlled, avoid fluid overload, maintain blood pressure, and preserve cardiac output. Verify the exact plan with your surgical or anesthesia team in case they want something different for you.
