What is grade 3 hypertension

When it comes to hypertension, everyone should be very familiar with it. There should be many patients with hypertension around us. Such a disease is not uncommon. Our daily living habits and eating habits can easily cause hypertension. Once hypertension occurs, it is difficult to cure. The important thing is to be able to do a good job of conditioning in daily life and prevent the condition from becoming more and more serious. If it develops into grade 3 hypertension, it will be very serious.

What is stage 3 hypertension?

Stage 1 blood pressure reaches the level of confirmed hypertension, with diastolic pressure fluctuating between 12.0 and 13.3 kPa (90 to 100 mmHg) most of the time and returning to normal after rest; stage 2 blood pressure reaches the level of confirmed hypertension, with diastolic pressure exceeding 13.3 kPa (100 mmHg) and failing to drop to normal after rest, and there are signs of left ventricular hypertrophy, general or local narrowing of the cranial basilar arteries, and slightly increased proteinuria; stage 3 blood pressure reaches the level of confirmed hypertension, with diastolic pressure exceeding 14.7 to 16.0 kPa (110 to 120 mmHg), and one of the following symptoms: cerebrovascular accident or hypertensive encephalopathy, left heart failure, renal failure, fundus hemorrhage or exudation, with or without papilledema.

Hypertension examination items

(A) Routine blood tests usually show no abnormalities in red blood cells and hemoglobin. However, in patients with acute hypertension, there may be microangiopathic hemolytic anemia with a negative Coombs test. Patients with abnormal red blood cells and high hemoglobin have increased blood viscosity and are prone to thrombotic complications (including cerebral infarction) and left ventricular hypertrophy.

(ii) Urinalysis: In the early stage, the patient's urine routine is normal. When the renal concentrating function is impaired, the urine specific gravity gradually decreases. There may be a small amount of urine protein, red blood cells, and occasional casts. As renal disease progresses, the amount of urine protein increases. In patients with benign nephrosclerosis, if the 24-hour urine protein is more than 1g, it indicates a poor prognosis. The number of red blood cells and casts may also increase, and the casts are mainly transparent and granular.

(III) Renal function is often estimated using blood urea nitrogen and creatinine. There are no abnormalities in the early examination of patients, but the level of renal plasma may begin to rise when the renal parenchyma is damaged to a certain extent. Creatinine levels >114.3 μmol/L in adults and >91.5 μmol/L in the elderly and pregnant women indicate renal damage. Phenol red excretion test, urea clearance rate, endogenous creatinine clearance rate, etc. may be lower than normal.

Everyone should have some understanding of stage 3 hypertension. Stage 3 hypertension is already very serious hypertension and is very harmful to patients. If it cannot receive scientific and timely treatment, the patient's life safety will be threatened. I hope everyone will pay attention to it.
