What are the precautions for patients with mitral stenosis in rheumatic heart disease?

For asymptomatic patients with mitral stenosis of rheumatic heart disease, they generally still have the ability to work for a long time, and if there are no symptoms such as palpitation, shortness of breath, and chest tightness after general daily physical activities, they can get married and have children; For such patients, one is to prolong the asymptomatic period as much as possible, and the other is to choose the right time for surgery as the disease progresses. The former mainly includes the prevention and control of rheumatic activities, such as sore throat, joint pain, cold and fever and other symptoms to seek medical attention in time, in addition, you can exercise appropriately but do not feel tired to avoid overwork. Do not consume too much water or watery food, drinks, fruits, etc., so as not to increase the burden on the heart. The latter is to choose an appropriate time for surgery. It is safer to have surgery very early, but because the symptoms are not severe before the surgery, there is no improvement after the surgery. Moreover, if the mechanical valve is replaced, you need to take anticoagulants after surgery, and you need to take blood tests frequently to see if the anticoagulant dosage is appropriate, which feels very troublesome; If you change to a bioprosthetic, although you do not need to take anticoagulants, the life of the bioprosthetic valve is limited. The operation was too late and I was afraid of delaying the condition. So what to do? Now it is generally looked at two points: one is whether there is a manifestation of heart failure, and the other is to see whether there is atrial fibrillation. The most easily detectable manifestation of the so-called heart failure is that you can't sleep on a general pillow as usual when sleeping, but you need to put the pillow high or even half sit and lie down to fall asleep, otherwise you will feel breathless, and some people will wake up from sleep after falling asleep. The so-called atrial fibrillation is that the heartbeat is particularly uneven, some people have a feeling of repeated chuckling or sudden panic in their hearts, and their pulse is fast and slow, if they are not sure, they can find out whether there is atrial fibrillation when they go to the hospital to check the electrocardiogram. Atrial fibrillation itself is not much danger to people, but after atrial fibrillation, it is easy to grow blood clots in the heart, and the blood clots are easy to fall off. If there are two manifestations of heart failure and atrial fibrillation, don't wait any longer, it's time for surgery, the surgical effect is better at this time, the condition will not be delayed, and it will not be too early.
