Heart Murmur
A heart murmur is a sound made by blood flowing through the heart's chambers or valves. These sounds can be normal or abnormal and may vary in duration and intensity. While murmurs can be common and harmless, some may signal underlying heart conditions. It's essential to monitor any changes in heart sounds and overall health.
Cardiovascular- What exactly is happening with my heart valves?MedlinePlusMay 2026
Your heart has four valves with flaps that open and close to keep blood flowing in the right direction. A heart murmur means one or more of these valves isn't working perfectly—the flaps might not close tightly, or they might be thick and stiff, which affects how blood moves through your heart.
- How does a heart murmur affect blood flow in my body?MedlinePlusMay 2026
When a valve doesn't work right, blood can leak backwards or not flow smoothly through your heart to your body. This makes your heart work harder and can reduce the amount of oxygen-rich blood reaching your organs and muscles.
- Can you explain what regurgitation means for me?MedlinePlusMay 2026
Regurgitation means the valve flaps don't close tightly enough, so blood leaks backwards instead of moving forward. This is like a door that doesn't shut all the way—some of what should go through gets pushed back.
- Why do some people get heart valve problems and others don't?MedlinePlusMay 2026
Heart valve problems can happen from birth, infections, rheumatic fever, age-related wear, or other heart conditions. Some people are born with valve issues, while others develop them over time from illness or aging.
- Is there anything I can do to prevent my condition from getting worse?MedlinePlusMay 2026
Follow your doctor's treatment plan, take medications as prescribed, and attend all follow-up appointments. Avoiding strenuous activity if recommended and managing other health conditions like high blood pressure can also help prevent your condition from worsening.
