People with obstructive HCM may be at increased risk for infective endocarditis, a potentially life-threatening condition. Ask your doctor if you need to take endocarditis precautions, which include:
Telling all your doctors and dentist you have HCM. They should prescribe antibiotics to prevent an infection before performing any procedures on you that may cause bleeding (dental, respiratory, and gastrointestinal procedures).
Calling your doctor if you have symptoms of an infection.
