What is a heart murmur, and what should be done about it?
In general, a heart murmur refers to an abnormal sound produced by blood flow through the heart, which may be caused by conditions such as anemia, chronic hypertension, pericarditis, valvular stenosis or insufficiency, or congenital heart disease. Depending on the underlying cause, targeted treatment should be carried out under medical guidance. Specific analyses are as follows:
1. Anemia: In anemia, insufficient oxygen transport in the blood may cause the heart to pump harder, resulting in a murmur, accompanied by symptoms such as fatigue, dizziness, and pallor. Medications such as ferrous gluconate syrup, iron dextran granules, and vitamin B12 tablets may be used as directed by a physician.
2. Chronic Hypertension: Long-term high blood pressure can overburden the heart, leading to murmurs, along with symptoms like headache, blurred vision, and chest pain. Under medical supervision, drug therapy—such as nifedipine tablets, labetalol hydrochloride tablets, or captopril sustained-release tablets—may be prescribed.
3. Pericarditis: Pericarditis involves inflammation that increases the thickness of the pericardial sac, affecting heart movement and producing a friction rub, often accompanied by chest pain, fever, and palpitations. It is recommended to follow medical advice and use medications such as ibuprofen capsules, amphotericin B for injection, or prednisolone tablets to relieve symptoms.
4. Valvular Stenosis or Insufficiency: Heart valve stenosis or regurgitation can lead to blood backflow, creating turbulent flow that produces a murmur, along with symptoms such as palpitations, shortness of breath, and fatigue. Medical evaluation and possible valve repair surgery may be required.
5. Congenital Heart Disease: Congenital heart defects may cause blood to flow into narrowed areas during circulation, generating murmurs, and are often associated with rapid breathing and delayed growth and development. Patients are advised to seek care at a reputable hospital for interventional procedures or surgery, and to manage their cardiac condition to alleviate symptoms.
Patients are encouraged to seek timely medical attention. Doctors will determine the exact cause of the murmur through physical examination, electrocardiogram (ECG), echocardiography, and other tests, and develop an appropriate treatment plan accordingly.
