In order to maintain the vital signs of the human body, the heart must have a fixed cardiac output to ensure the blood supply and nourishment of the body, therefore the cardiac output is definite as per the body's needs. When there is severe mitral valve regurgitation, it causes a decrease in the stroke volume. As a compensation, while the stroke volume decreases, in order to ensure the body's blood supply and nourishment, the heart accelerates its beating to maintain the supply of output. Therefore, patients with mitral valve regurgitation often experience symptoms of tightness in the chest, difficulty breathing, and palpitations after exercising. This means that our heart rate after exercise will be faster than in people without mitral valve regurgitation, thus mitral valve regurgitation affects the heart rate.

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.

Will mild mitral valve insufficiency become more severe?

If the patient has a history of mitral valve insufficiency, and if it is not treated timely, the condition will worsen. If the patient develops heart failure, sometimes it is necessary to actively correct the heart failure, because the most serious complication of this disease is heart failure, which is quite severe. Once the patient's heart function changes, especially if the ejection fraction decreases, it can lead to ischemic and hypoxic changes in the patient. In terms of treatment, it is also important to monitor the patient's blood pressure, heart rate, and pulse changes, while actively controlling the heart rate.

Will mild mitral valve regurgitation worsen?

Because mitral valve insufficiency is a type of heart valve disease and also a form of rheumatic heart disease, mild mitral valve insufficiency can be actively managed with internal medicine, thereby alleviating the patient's symptoms. However, this disease can potentially worsen, especially in cases of mild insufficiency. When cardiac function becomes impaired, it can lead to severe insufficiency. In such cases, surgical treatment is sometimes recommended for the patient. If the patient's cardiac function is actively managed, infections controlled, and regular hospital check-ups are maintained, improvement can be achieved.

Can mitral valve insufficiency run?

Patients with mitral valve stenosis and insufficiency are advised not to run, as running is an aerobic exercise that increases heart rate. This can lead to symptoms like palpitations, chest tightness, and difficulty breathing, which are indicative of the heart needing more oxygen supply. Moreover, running increases the heart rate, which in turn increases the myocardial oxygen consumption and is detrimental to health. Particularly, running with mitral valve insufficiency is very dangerous. It is recommended to rest primarily and avoid participating in sports, especially running, for the health of the patient.

Is mild to moderate mitral valve regurgitation serious?

If the patient has a history of mitral valve insufficiency, especially in moderate cases, it is considered quite severe. The current treatment mainly focuses on symptomatic treatment to improve the patient's cardiopulmonary function. If the patient experiences palpitations, chest tightness, or difficulty breathing, sometimes intravenous therapy is required to alleviate the current condition. Because for congenital heart disease or rheumatic heart disease, the treatment primarily involves strengthening the heart, diuresis, vasodilation, symptomatic treatment, and management. If not treated and managed promptly, the disease could worsen, and the patient may also develop swelling in both lower limbs.
