Cold weather and chest tightness

Women are tall and thin, and are generally the favorite candidates for models; However, in the eyes of cardiologists, this is not the case. Tall, thin and sentimental women are often candidates for mitral valve prolapse. Especially in cold weather, patients will have chest tightness, palpitation, cold sweat, dizziness and other uncomfortable symptoms. Chinese medicine believes that mitral valve prolapse is mainly caused by deficiency of both qi and blood. In addition to acupuncture treatment, you can also eat Shengmai drink in moderation to replenish your vitality and adjust it according to your physique.

Possible symptoms of mitral valve prolapse: palpitation, panic, breathlessness, chest tightness, chest pain, etc.

The human heart has four valves, including aortic valve, mitral valve, tricuspid valve and pulmonary valve. The mitral valve is located between the left atrium and the left ventricle. It is also called mitral valve because it looks like a bishop's hat. It is mainly responsible for separating blood flow between two atria. When the left ventricle contracts, in order to ensure that blood can flow into the aorta smoothly, the mitral valve will close to prevent blood from flowing back to the left atrium. When the left ventricle relaxes, the anterior and posterior leaflets of the mitral valve will open again, allowing oxygenated blood to flow from the lungs into the left atrium through the pulmonary veins, thus entering the left ventricle.

There are more women with mitral valve prolapse than men, and the biggest feature is that they are tall and thin and have low blood pressure.

However, in the process of embryo growth, if the valve connective tissue changes mucus, the valve will become soft and too long, and it may prolapse in the future. Once mitral valve prolapse occurs, when the patient's left ventricle contracts, the mitral valve cannot be completely closed due to prolapse, which will cause partial blood backflow, which will not only produce systolic heart murmur, but also reduce the blood supply to the heart. Patients may feel a little chest tightness or wheezing only after strenuous exercise. However, some critically ill patients will feel flustered, panic, shortness of breath, chest tightness and chest pain in their daily activities, and even affect their daily life and work performance. This situation is particularly prone to occur when the temperature difference between autumn and winter is large and the weather is cold.

Mitral valve prolapse is one of the most common heart valve abnormalities. About 5% people suffer from this kind of prolapse, and the incidence of female patients is twice that of male patients. The biggest characteristics of this kind of patients are thin, tall, low blood pressure and even easy to be sentimental.

Once mitral valve prolapse occurs, when the patient's left ventricle contracts, the mitral valve cannot be completely closed due to prolapse, which will cause some blood backflow, which will not only produce systolic heart murmur, but also reduce the blood supply to the heart.
