The manifestation of rheumatic heart disease is not specific, in the early stage of rheumatic heart disease with mild lesions, there may be no manifestation. Within a certain period of time, through compensatory function, the heart can still maintain its normal functional state; if the compensatory function is dysfunctional, regardless of stenosis or incomplete closure, it can cause a series of clinical manifestations of heart failure, shortness of breath with cough on exertion is the earliest symptom; but when the heart valve damage is serious and affects the heart function, it can produce various symptoms. In severe cases, heart failure may occur, including dyspnea, seated breathing, inability to lie down at night, swelling, abdominal distension, ascites, enlargement of liver and spleen, etc. Depending on the heart valve damage, examination may reveal signs such as enlarged heart, systolic and/or diastolic murmur on auscultation, or arrhythmia, liver enlargement, and ascites. If the lesion is mild and attention is usually paid to it, there may be no obvious conscious symptoms and it will not affect life and work, and it can live normally into old age. However, if left unattended or improperly treated, adverse or even serious consequences may occur, such as recurrence of rheumatic fever, infective endocarditis, atrial fibrillation, heart failure and cerebral embolism, all of which are serious complications of rheumatic heart disease. These are serious complications of rheumatic heart disease. If you do not seek medical attention in time or if you do not seek medical attention properly, you will suffer from lifelong disability or even death. Therefore, once rheumatic heart disease is diagnosed, it should be actively treated and prevented from complications, which can seriously affect the patient’s quality of life. How to diagnose rheumatic heart disease? What is the treatment method? The diagnosis of rheumatic heart disease mainly relies on medical history, symptomatic manifestations and detailed physical examination, electrocardiogram, echocardiogram, X-ray, etc., which are very helpful for the diagnosis of rheumatic heart disease. In some patients, cardiac catheterization and cardiography are also performed when necessary to confirm the diagnosis. If there are no conscious symptoms, it is usually not necessary to take medication every day. Take proper rest, avoid overwork (mental and physical), eat a light diet, eat nutritious, vitamin-rich and easily digestible food, and prevent the recurrence of colds and rheumatic fever so as not to aggravate the burden on the heart and aggravate the disease. If you have any self-conscious symptoms, you should go to the hospital for consultation and treatment. In the past ten years or so, the development of heart surgery has brought hope to some patients with critical rheumatic heart disease. Many patients have improved their heart function, saved their lives and partially or completely recovered their labor force through surgical treatment. For those who are suitable for surgery, it is necessary to make a decision at once, and the patients themselves, their families and doctors will work together to cure the disease. For those who are not suitable for surgery or temporarily not suitable for surgery, through reasonable medication, injection and other medical treatment, we can also achieve results, improve the patient’s heart function and create opportunities for future surgery.
