Long-term low blood pressure, blood pressure 80/50mmHg, generally divided into physiological and pathological reasons, physiological belongs to the normal, generally no need to deal with; myocarditis, cardiomyopathy, hypothyroidism, etc. can cause long-term low blood pressure, and long-term low blood pressure state is easy to cause myocardial ischemia, cerebral ischemia, renal damage.
1. Physiological long-term hypotension: some old people and thin women, the blood pressure can be slightly lower than 90/60mmHg, but the body is healthy, there is no other disease, generally will not lead to poor prognosis, no special treatment, strengthen nutrition can be.
2. Pathological long-term low blood pressure: myocarditis, cardiomyopathy, hypothyroidism, etc. can cause long-term low blood pressure, and this state usually leads to myocardial ischemia, cerebral ischemia, and kidney damage.
(1) Myocardial ischemia: long-term low blood pressure, blood stasis leads to insufficient perfusion of the heart, myocardial ischemia can be manifested as angina pectoris, myocardial infarction, etc. Patients experience pressure pain in the precordial region, cold sweating, panic and other discomforts, which can be clarified by coronary artery CTA or angiography and other tests.
(2) Cerebral ischemia: long-term low blood pressure leads to insufficient cerebral perfusion, which can lead to cerebral ischemia, cerebral infarction, transient ischemic attack, and patients show dizziness, unfavorable speech, and reduced muscle power of lateral limbs, etc., which can be clarified by cranial CT or nuclear magnetic examination.
(3) Kidney damage: long-term hypotension can cause kidney ischemia, which leads to kidney damage such as reduced glomerular filtration rate and tubular damage, and patients can show oliguria and proteinuria, which can be clarified by kidney function or ultrasound and other tests.
If the patient has long-term low blood pressure, blood pressure 80/50mmHg, it is recommended to go to the hospital and follow the doctor’s instructions for treatment.
