The obstruction of blood ejection from the left ventricle indicates resistance to the ejection function of the left ventricle. Normally, in a normal person blood is circulated by ejecting blood from the left ventricle, which then travels to the aorta and will reach the heart after passing through the circulation. The left ventricle ejects blood impedance most likely because the aortic valve pressure is too high or too narrow, the left ventricle in the delivery of blood to the blood vessels of the whole body, because the blood vessels are too narrow, so that the flow of blood is not subject to greater resistance, should promptly go to the hospital to do the relevant examination to find the cause of the disease, and then for symptomatic treatment. The daily diet should be light, and should be small and frequent, do not overeat, do more sports to enhance physical fitness, control the weight within a reasonable range, and control blood pressure, blood lipids and blood sugar.
