Medicines:

You may need any of the following:

• Blood thinners help prevent blood clots. Clots can cause strokes, heart attacks, and death. Many types of blood thinners are available. Your healthcare provider will give you specific instructions for the type you are given. The following are general safety guidelines to follow while you are taking a blood thinner:
  • Watch for bleeding and bruising. Watch for bleeding from your gums or nose. Watch for blood in your urine and bowel movements. Use a soft washcloth on your skin, and a soft toothbrush to brush your teeth. This can keep your skin and gums from bleeding. If you shave, use an electric shaver. Do not play contact sports.
  • Tell your dentist and other healthcare providers that you take a blood thinner. Wear a bracelet or necklace that says you take this medicine.
  • Do not start or stop any other medicines or supplements unless your healthcare provider tells you to. Many medicines and supplements cannot be used with blood thinners.
  • Take your blood thinner exactly as prescribed by your healthcare provider. Do not skip a dose or take less than prescribed. Tell your provider right away if you forget to take your blood thinner, or if you take too much.
• Heart medicine is given to strengthen or regulate your heartbeat.
• Diuretics help get rid of extra fluid that collects in a part of your body, such as your legs. Diuretics can also remove fluid from around your heart or lungs and lower your blood pressure. You may urinate more often when you take this medicine.
• Blood pressure medicine is given to lower your blood pressure. Take your blood pressure medicine exactly as directed.
• Prescription pain medicine may be given. Ask your healthcare provider how to take this medicine safely. Some prescription pain medicines contain acetaminophen. Do not take other medicines that contain acetaminophen without talking to your healthcare provider. Too much acetaminophen may cause liver damage. Prescription pain medicine may cause constipation. Ask your healthcare provider how to prevent or treat constipation.
• Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Drugs used to treat this and similar conditions

Activity and rest:

• You may feel like resting more after this procedure. Slowly start to do more each day. Rest when you feel you need to.
• Ask when you can return to your daily activities. You may need to wait 4 to 6 weeks after the procedure. Your healthcare provider will tell you which activities you should avoid. These may include driving while you are taking pain medicines. You may also be told not to lift objects that are over a certain weight.
• Ask about exercises that are safe for you. Walking is a good way to improve your overall health and help you recover. Walking also helps keep your blood flowing and reduces the risk of blood clots. Other types of exercise can also be an important part of your recovery. Your healthcare provider can tell you the exercises that are right for you.

Wound care:

Your healthcare provider will tell you when it is okay to bathe or shower. You may need to wash the incisions with soap and water. Pat the area dry. Then put on new, clean bandages as directed. Change your bandages when they get wet or dirty.

Do not drink alcohol:

Alcohol may worsen your heart condition or interact with your heart medicine. Tell your healthcare provider if you drink alcohol and you need help to stop.

Do not smoke:

Nicotine and other chemicals in cigarettes and cigars can cause heart and lung damage. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.

Lower your risk for arrhythmia:

High blood pressure, sleep apnea (pauses in breathing while asleep), and obesity increase your risk of arrhythmia. Talk to your healthcare provider about ways to prevent or manage these risk factors.

Follow up with your doctor or cardiologist as directed:

Write down your questions so you remember to ask them during your visits.
