To solve the problem of low differential pressure, we must first identify the causes of low differential pressure, there is no quick fix, we need to actively treat the cause of the problem, the treatment mainly includes the treatment of the cause of the problem and adjust the lifestyle. Differential pressure can be caused by pericardial effusion, severe mitral valve stenosis, severe heart failure and other reasons that reduce the pumping ability of the heart, resulting in a decrease in systolic blood pressure, causing a decrease in differential pressure, or due to blood stasis, increased cardiac preload, resulting in an increase in diastolic blood pressure, causing a decrease in differential pressure. Depending on the cause of the disease, the treatment methods are also different. 1. Treatment for the cause: Individualized comprehensive treatment should be carried out for the cause of the decreased pressure difference, such as pericardial effusion should be pericardiocentesis; for mitral stenosis, valve replacement can be performed; for severe heart failure, anti-heart failure treatment should be carried out, including cardiotonic, diuretic, vasodilator, etc. 2. Adjustment of daily routine: for patients with reduced differential pressure, due to insufficient pumping of the heart, reduced systemic blood volume, poor blood supply to the tissues, there will often be tissue hypoxia, generalized weakness, fainting and other manifestations, at this time, you can appropriate exercise, a healthy diet, to avoid aggravating the burden on the body, so as to avoid accidents. Differential pressure should be timely and active treatment, the patient should go to the hospital for further examination to clarify the cause of the disease, follow the doctor’s instructions, so as not to delay treatment.
