The usual common hazards of having a low blood pressure higher than 90 mmHg are the development of hypertensive complications in the heart, kidneys, eyes, and brain.
Hypertension is diagnosed by a low blood pressure ≥ 90 mmHg and/or a high blood pressure ≥ 140 mmHg, and is therefore diagnosed in people with a low blood pressure higher than 90 mmHg, regardless of what the high pressure is. Hypertension in general may not have obvious symptoms of self discomfort, but it can cause damage to the heart, kidneys, eyes, brain, and so on.
1. Heart damage: Long-term high blood pressure may cause cardiac diastolic dysfunction, resulting in hypertensive heart disease and myocardial hypertrophy, which in turn leads to myocardial ischemia. Patients may experience symptoms such as panic and palpitation after exertion, and in severe cases, pressure-like pain in the precordial region may occur, even leading to myocardial infarction, which is life-threatening.
2. Kidney damage: long-term high blood pressure will also have damage to the kidneys, resulting in decreased renal function, glomerulopathy, protein in the urine, shrinkage of the kidneys, abnormal renal function and even renal failure.
3. Eye damage: high blood pressure on the fundus arteriosus is also very big, can cause blurred vision, fundus hemorrhage and other hazards.
4. Brain damage: long-term high blood pressure can lead to cerebral arteriosclerosis, cerebral artery aneurysm, etc., which may lead to cerebral infarction, cerebral hemorrhage, etc., which is life-threatening.
Therefore, patients with high blood pressure must strictly comply with the doctor’s instructions to use medication, do not change the drug without authorization to stop, but also pay attention to low-salt and low-fat diet, appropriate exercise, regular review.
