The harm caused by high impedance of left ventricular jet is mainly manifested in the head, heart, kidneys and other locations. High impedance of left ventricular ejection tends to cause aortic stenosis and infarction, resulting in insufficient blood supply to the periphery of the heart, leading to a decrease in peripheral blood supply, and also leading to an increase in the pressure of the heart causing myocardial hypertrophy, which ultimately leads to heart failure, palpitations (accelerated heartbeat, often accompanied by panic), shortness of breath, and tightness in the chest and other symptoms. 1. Head: manifested in the head, the patient will show dizziness, fainting and even loss of consciousness. 2. 2. Heart: manifested in the heart, it may cause insufficient blood supply to the coronary arteries of the heart, resulting in angina pectoris or even myocardial infarction. 3. Kidney: manifested in the kidneys, it will lead to the reduction of renal perfusion, and with the development of the disease will also cause the gradual decline of renal function. When patients have high impedance of left ventricular jet, they should go to the hospital in time to do the relevant examination to find the cause of the disease, and under the guidance of professional doctors, they should carry out symptomatic treatment in combination with their personal situation. In daily life, the patient’s diet should be light, eat small meals to avoid overeating, appropriate sports exercise, for the disease has a more positive effect on the relief of the improvement.
