If the low pressure is at 45mmHg for a long period of time is more dangerous, it will cause insufficient blood supply to important organs of the body such as the heart, brain, kidney, etc., and in serious cases, it will lead to the failure of various organs, which is life threatening.
Clinically, a systolic blood pressure of less than 90mmHg and a diastolic blood pressure of less than 60mmHg is called hypotension. Low blood pressure will lead to insufficient blood supply to the heart, brain, kidneys and other important organs. Long-term low blood pressure will lead to impaired function and even failure of various organs, resulting in death.
1. Heart: low blood pressure will lead to insufficient blood supply and perfusion to the heart from the coronary artery, resulting in panic, chest tightness, angina symptoms, and in severe cases, myocardial ischemia, heart attack and heart failure;
2. Cerebrovascular: low blood pressure will cause insufficient cerebral perfusion, mental inattention, fatigue, profuse sweating, dizziness, fainting and other symptoms, which can cause watershed cerebral infarction in serious cases;
3. Kidney: prolonged low blood pressure will lead to decreased renal perfusion, symptoms of oliguria and anuria, and in serious cases, cause renal insufficiency and even renal failure.
Therefore, blood pressure should be measured regularly, and if abnormal blood pressure is found, timely consultation should be made, and appropriate treatment should be given for different reasons to avoid causing damage to the function of various organs and danger.
