What are the main and important symptoms of Keshan disease?
summary
Keshan disease, also known as endemic cardiomyopathy, was discovered in Keshan County, Heilongjiang Province in 1935, hence its name. According to the investigation, the acute Keshan disease disappeared in 1980. The main manifestations were acute and chronic cardiac insufficiency, cardiac enlargement, arrhythmia and embolism of brain, lung and kidney. Now let's talk about the main and important symptoms of Keshan disease.
What are the main and important symptoms of Keshan disease?
According to the state of cardiac function, Keshan disease can be divided into acute type, subacute type, slow type and latent type. The first three were decompensated cardiac function, and the latter were compensated. Acute type is characterized by acute cardiac insufficiency, often combined with cardiogenic shock and severe arrhythmia. Subacute type mainly occurs in children, with systemic edema and congestive heart failure. Chronic congestive heart failure (CHF) is the main manifestation of chronic CHF, which can occur gradually, and can also be transited from acute type or subacute type. The latent heart function is good, most of them have no self-conscious symptoms, occasionally have arrhythmia and ECG changes.
Acute type of this type of onset in winter, the onset of sudden, rapid changes, often in the cold, overwork, cold, mental stimulation, overeating or women's childbirth and other cardiac load aggravation inducement effect. The most common manifestation is cardiogenic shock, accounting for about 75% of acute severe Keshan disease. The main symptoms of the patients are nausea, severe vomiting and dizziness, and the main complaints are dizziness, epigastric discomfort, chest tightness, palpitation and dyspnea. Severe cases can die within hours. 67% - 82% of the patients had heart enlargement, galloping rhythm, pulmonary rales, hepatomegaly, edema and shock. This type is often complicated with severe arrhythmias, manifested as multiple ventricular premature contractions, ventricular tachycardia and various degrees of atrioventricular block. 20% of patients may have A-S syndrome. A few (< 5%) patients showed acute left ventricular dysfunction or pulmonary edema caused by pulmonary congestion. Cardiogenic shock, arrhythmia and pulmonary edema often coexist. If the signs of hepatomegaly and edema do not subside for more than 3 months, it is suggested that the acute type will change to the slow type.
The onset of the slow type is slow, it can be gradually from the asymptomatic stage, and it can also be transited from other types. The main clinical manifestations of chronic congestive heart failure include palpitation, dyspnea, edema, liver congestion, enlargement of heart boundary, weakening of the first heart sound, galloping horse rhythm and various arrhythmias, especially ventricular premature contraction and atrial fibrillation, relative murmur of mitral and tricuspid insufficiency, pleural effusion and arrhythmia Ascites and pericardial effusion, as well as the corresponding symptoms and signs. Complications of chronic cardiac insufficiency, such as pulmonary infarction, can also occur. In addition, as the thrombus attached to the wall of the heart falls off, embolism may occur in the brain, kidney, spleen, mesentery, etc.
matters needing attention
For Keshan disease, a very dangerous disease, active prevention is also very important, which requires people to develop a healthy sense of life, use their spare time to learn more medical knowledge, always pay attention to their physical changes, and regularly go to the hospital for physical examination. At ordinary times, we should keep a good attitude and get in touch with nature. At ordinary times, we should strengthen nutrition supplement, eat more fresh fruits and vegetables, such as tomatoes, pitaya, spinach, celery, Hami melon, etc., drink more water, eat less and have more meals, don't overeat, don't smoke and drink, and the staple food should be coarse grains, which are very important.
