Mitral stenosis primarily restricts the return blood volume to the left ventricle. If the stenosis is particularly severe, it can lead to a significant decrease in return blood volume, resulting in poorer pumping function. There are several main factors that affect return blood volume. The first is sufficient circulating blood volume, and the second is the degree of mitral stenosis. Therefore, after using vasodilators, a large amount of blood flows into the capacitance vessels. As a result, the return blood volume decreases, which can further reduce the return blood volume through the already narrowed mitral valve, leading to worsening breathing difficulties in patients, severe cases can cause fainting, or even sudden death.

Can you eat preserved eggs with mitral stenosis?

If the patient has a history of mitral stenosis, it is recommended that they follow a low-salt, low-fat, and low-sugar diet, eat small meals frequently, and especially avoid spicy and stimulating foods. Century eggs are permissible to eat but should be consumed in moderation, one is enough. At the same time, the diet should be diversified and balanced with an emphasis on enhancing nutrition, which is most important. It is also advisable for the patient to limit their sodium intake to help alleviate symptoms. Currently, treatment primarily focuses on symptomatic relief. It is also crucial to actively control the patient's blood pressure, heart rate, and pulse changes. If there is an increase in blood pressure or if the heart rate is too fast, these conditions need to be actively managed to control the heart rate and improve cardiac function.

Do young people have mitral valve regurgitation?

Mitral valve regurgitation is a type of congenital heart disease that tends to occur in children, adolescents, or the elderly. Young people can also develop mitral valve regurgitation. To diagnose this condition, an echocardiogram is necessary, as it allows for a more definitive diagnosis. In terms of treatment, symptomatic treatment is often primary, using cardiotonic diuretics to improve the patient's heart function. During this period, it is important to monitor changes in the patient's vital signs, especially heart rate, pulse, and blood pressure. If the heart rate is too fast, efforts should sometimes be made to actively control ventricular force, thereby reducing the load on the heart.

Is mild mitral regurgitation a disease?

Mild mitral regurgitation can be caused by diseases or it can also be seen in healthy individuals. In healthy people, as age increases, the valve may experience some aging, leading to mild regurgitation. This mild mitral regurgitation is not considered a pathological condition and does not require treatment. Of course, mild mitral regurgitation can also be seen in some organic heart diseases, most commonly due to heart enlargement caused by various diseases leading to relative mild mitral regurgitation. For mild mitral regurgitation caused by diseases, it is important to effectively treat the related diseases to maintain stability of the condition, to prevent the disease from worsening and causing the heart to enlarge further, leading to more severe mitral regurgitation.

Why does mitral stenosis cause enlargement of the left atrium?

Because mitral stenosis can lead to changes in the mitral valve, particularly causing excessive pressure in the left ventricle, this excessive pressure can lead to enlargement of the left atrium, which are complementary conditions. During this period, it is still important to actively manage the condition, using medication treatment. If the area of stenosis is relatively large, surgical treatment is needed, as balloon dilation can currently be used to alleviate this condition. Early treatment is best to relieve clinical symptoms. At the same time, it is also important to actively monitor changes in heart rate, blood pressure, and pulse, so as to control the heart rate and reduce myocardial oxygen consumption.

Mitral stenosis increases the load on which ventricle?

If a patient exhibits symptoms of mitral stenosis, it primarily leads to an increased load on the left atrium and left ventricle, resulting in palpitations, chest tightness, and difficulty breathing. The current treatment mainly involves symptomatic therapy, using cardiotonic and diuretic medications to improve the patient's condition. Currently, medications are used in treatment to control symptoms like palpitations and chest tightness. It is advised that the patient should undergo a cardiac echocardiography to further confirm the diagnosis. In treatment, it is still necessary to control blood pressure, heart rate, and pulse changes. If there is a rapid heart rate or increased blood pressure, these should also be actively managed to reduce the cardiac load. Dietarily, it is recommended that patients adopt a light diet, particularly eating smaller, more frequent meals and avoiding spicy and irritating foods. It’s important to keep warm and avoid catching cold.
