If the patient’s low pressure is 46 mmHg, this is a more severe form of hypotension and is relatively dangerous, but it should also be combined with what the patient’s current systolic blood pressure is approximately, which will help gauge whether the current risk is greater. Because some patients may simply have low diastolic blood pressure, which is what maintains the perfusion of various organs, so if the diastolic blood pressure is low it may induce myocardial ischemia, cerebral ischemia, renal ischemia, resulting in renal failure, heart failure and angina pectoris, which is said to be relatively dangerous. It is recommended that patients with low diastolic blood pressure should pay attention to adjusting the drug use program, for some drugs that affect blood pressure, try to eat less or not, but also appropriate oral pulse drink such drugs to raise the patient’s blood pressure.
