To prevent heart valve disease caused by rheumatic fever, see your doctor if you have signs of a strep infection. These signs include a painful sore throat, fever, and white spots on your tonsils. If you do have a strep infection, be sure to take all medicines prescribed to treat it. Prompt treatment of strep infections can prevent rheumatic fever, which damages the heart valves.
It’s possible that exercise, a heart-healthy diet, and medicines that lower cholesterol might prevent aortic stenosis (thickening and stiffening of the aortic valve). Researchers continue to study this possibility.
Heart-healthy eating, physical activity, other heart-healthy lifestyle changes, and medicines aimed at preventing a heart attack, high blood pressure, or heart failure also may help prevent heart valve disease.
