Mitral valve regurgitation can cause backflow, as it is a type of rheumatic heart disease. Currently, treatment primarily focuses on symptomatic relief and improving the patient’s cardiopulmonary function. During this period, it is still important to actively monitor the patient’s heart rate, blood pressure, and pulse changes. If there is a rapid heart rate or increased blood pressure, these conditions need active intervention to alleviate the patient’s state of ischemia and hypoxia. If there is significant regurgitation, it may lead to a state of hypoxia. During this period, it is still important to actively monitor the patient’s heart rate, blood pressure, and pulse. Regular follow-up with cardiac echocardiography is adequate, and it is also necessary to actively prevent upper respiratory infections.

Why does mitral valve regurgitation cause left ventricular hypertrophy?

Mitral valve insufficiency leads to left ventricular hypertrophy. This occurs because when the mitral valve does not close fully, the contraction of the ventricles often causes the blood in the left ventricle to flow back into the left atrium, resulting in a significant increase in the blood volume of the left atrium. When the ventricles relax the next time, the left ventricle receives a large amount of blood from the left atrium, as well as the remaining original blood. This causes a significant increase in the capacity and load of the left ventricle, and over time leads to enlargement and hypertrophy of the left ventricle. This condition eventually leads to the appearance of symptoms of heart failure, causing the patient to repeatedly experience difficulty in breathing.

What to do about chronic cough due to mitral valve insufficiency?

If the patient exhibits mitral regurgitation, this condition falls under cardiac valvular diseases. If the patient frequently experiences coughing and expectorating phlegm, it indicates a certain level of inflammatory infection. It is recommended for the patient to undergo a chest CT scan for an effective confirmation of the cause, which will then determine the treatment plan. For simple mitral stenosis, symptomatic treatment is currently the primary approach, using medications to address heart failure or ischemia and hypoxia. Early treatment is advised to alleviate the current state of ischemia and hypoxia. Persistent coughing and expectorating phlegm indicate inflammation, necessitating the use of antibiotics.

Can you drink alcohol with mitral valve insufficiency?

If the patient has a history of mitral stenosis or mitral regurgitation, they should avoid alcohol as it can lead to a series of side effects, especially symptoms such as chest tightness, palpitations, and difficulty breathing. If drinking alcohol results in elevated blood pressure, it requires proactive management, especially for those with heart valve diseases. It is advised that patients focus on a diet rich in high-quality protein and low in salt, fat, and sodium. Regular echocardiographic check-ups are also essential. If the patient has no special complications, active treatment is needed, which usually involves using medications to improve cardiac function.

Why does the pulse pressure increase with mitral valve insufficiency?

Mitral valve regurgitation leading to an increased pulse pressure difference is a very common phenomenon, which is related to the condition of mitral valve regurgitation itself. This is because when the left ventricle is in systole, the incomplete closure of the mitral valve causes the blood in the left ventricle to flow back into the left atrium, significantly increasing the volume of blood in the left atrium. When the ventricle is in the diastolic filling phase, a large amount of blood from the left atrium enters the left ventricle. At the same time, the left ventricle receives blood from the left atrium as well as the blood remaining from the systolic phase of the ventricle, resulting in a significant increase in the volume of blood the ventricle pumps. This leads to a notable rise in systolic pressure, thereby increasing the pulse pressure difference.

Is mitral valve regurgitation due to incomplete closure congenital?

If the patient has a history of mitral valve insufficiency accompanied by regurgitation, it may indicate congenital heart disease, but it does not rule out rheumatic heart disease caused by other illnesses. Because of this, it may indeed be a type of congenital heart disease, and some surgical treatments can be used, which are relatively safe. During this period, it is still necessary to actively monitor changes in the patient's blood pressure, pulse, and heart rate. If there is an increase in blood pressure or an overly rapid heart rate, it needs to be actively managed. Early intervention and treatment can alleviate the current condition of the patient. Based on this situation, it is recommended to just perform a cardiac echocardiogram.
