What Are the Different Types of Heart Murmur Treatment?

Heart murmur (cardiac murmur) refers to the abnormal sounds produced by the vibration of the walls, valves, or blood vessels caused by turbulence in the heart or blood vessels when the heart contracts or relaxes, in addition to heart sounds and extra heart sounds. Noise with different intensity and longer duration. Heart murmurs can be seen in healthy people and more often in patients with cardiovascular disease. Some murmurs are the main basis for diagnosing heart disease. For example, mitral stenosis can be diagnosed if there is a progressive rumbling murmur in the middle apex with pre-systolic systole.

Cardiac murmur

General inspection
If you have cyanosis, clubbing fingers (toes), or asthma, consider congenital cardiovascular malformations. The left margin of the sternum is mainly found in congenital heart disease or chronic rheumatic heart valve disease, and can also be caused by a large amount of pericardial exudate during childhood. There is a bulge or systolic impulse at or near the second intercostal space of the right margin of the sternum, which is mostly a sign of aortic arch aneurysm. Emphysema, pericardial effusion or left pleural effusion, pneumothorax signs can often mask or weaken the original heart murmur.
2. Heart auscultation
The patient should take a sitting or supine position, and if necessary, can ask the patient to change position. For example, the mitral valve murmur is often heard clearly in the left lying position; the murmur of aortic valve insufficiency is more clear in the sitting or standing position. During auscultation, you should also pay attention to the time of the murmur in the cardiac cycle (systole or diastole), the loudest part, the pitch level, the loudness, the sound quality (air blow, rumbling, machine sound, music sound), whether conduction, conduction Direction, exercise, breathing, body position, etc. to determine its clinical significance.
3. Other
If necessary, a chest radiograph, electrocardiogram, and echocardiography are performed to make a precise assessment of the condition.

Differential diagnosis of cardiac murmur

Pericardial fricative
The pericardial friction sound is high-pitched, similar to the sound produced by leather friction, and is often louder in the 3 to 4 intercostal space on the left edge of the sternum. It can occur during systole, diastole or second phase, and is communicative, which can cover heart sounds. Generally in the seated position, with the upper body leaning forward slightly (easy to hear when holding your breath, the sound is enhanced when the stethoscope chest piece is pressurized. When the friction sound is bright and rough, it is similar to the systolic murmur, but it has a short duration, only a few hours to a few days This is different from murmurs. The pericardial friction sounds auscultate like pleural friction sounds, but the pleural friction sounds disappear when you stop breathing, while the pericardial friction sounds still appear with the heart beat.
2. Cardiopulmonary murmur
When the heart beats, it is caused by squeezing the lungs near the heart to cause air movement in the lungs, which mostly occurs during systole. The murmur is limited to the middle phase of contraction, with a high pitch, and is easy to hear on the right apex and along the left edge of the heart. Clearer when inhaling. Can suddenly disappear. Seen when the pleura and mediastinum are widely adhered, also seen in normal people.
3. Peripheral vascular noise
When the artery is locally dilated (such as an aneurysm) or narrowed (such as atherosclerosis, constrictive arteritis tip), it is not necessary to pressurize at the lesion site, which is equivalent to the systole of the heart to hear murmur. Arteriovenous fistula can hear continuous murmur, aortic valve insufficiency, with a stethoscope chest piece gently press the brachial artery or femoral artery and other aorta, you can smell two murmurs, called Dirozier's double murmur. Aortic stenosis systolic heart murmur can be heard along the bloodstream and heard at the right subclavian or carotid artery. Continuous murmurs can also be heard at the varicose veins.
4. Pleural fricative
Pleuritis, incomplete inflammatory adhesions of the pleura, pleural tumor nodules, when the pleura is highly dry (such as cholera), the pleura becomes dry, and the two layers rub against each other and emit a dry, intermittent sound during breathing. At the end of exhalation, it is clearest at the beginning of inhalation. Hold your breath and stop it. Breathe deeply and pressurize with the chest piece of the stethoscope to strengthen it. When the pleural friction sounds occur near the heart, each heartbeat will cause friction sounds--pleural pericardial friction sounds .

Cardiac murmur treatment principles

1. If there is a noise in the heart, you should go to the hospital regularly to check the nature of the noise. If it's physiological, don't worry about it.
2. If the murmur is suspected to be pathological, it is necessary to determine whether there is an organic heart disease and timely treatment for the cause.
3. Anyone with pathological murmur caused by congenital heart disease or rheumatic heart disease should limit physical activity to prevent heart failure and severe arrhythmia. Doctors need to be checked to determine whether there are indications for surgical repair or valve replacement .
4. It is suggested that patients with congenital heart disease, rheumatic heart disease or mitral valve prolapse should be given antibacterial drugs prophylactically before tooth extraction.
