What is the harm of high blood pressure: three hazards

summary

Hypertension is the primary risk factor of cardiovascular and cerebrovascular diseases. If not treated in time, hypertension will lead to cerebral hemorrhage, arteriosclerosis, myocardial infarction, renal failure and blindness. The harm of hypertension is very great, we must attach great importance to it. So what are the hazards of hypertension?

What is the harm of high blood pressure: three hazards

First, the main direct complication of hypertension is cerebrovascular disease, especially cerebral hemorrhage. A group of 312 hospitalized patients with essential hypertension were followed up for 15-18 years. 97 cases died of cardiac, cerebral and renal complications, accounting for 74.6% of the total causes of death. In the prospective 27 month follow-up study of 596 elderly patients with hypertension, the cumulative incidence of cardiovascular and cerebrovascular diseases was 68.79%, and the cumulative incidence of cerebrovascular diseases was 36.91%. Studies have shown that the higher the blood pressure, the higher the incidence of complications. The study on the relationship between blood pressure and stroke in 5456 people over 15 years old in Baoshan District of Shanghai showed that the incidence of cerebrovascular disease in patients with hypertension accounted for about 70% of the total number of cerebrovascular disease in the population during the 9-year follow-up period. The relative risk of cerebrovascular disease in patients with hypertension was 32 times higher than that in those with normal blood pressure, and the borderline hypertension was also as high as 9 times.

Second: cause kidney disease, long-term hypertension can lead to renal arteriosclerosis. When renal function is decreased, it can cause nocturia, polyuria, proteinuria, casts and red blood cells. Low concentration of urine, phenol red excretion and urea clearance. Azotemia and uremia occurred.

Third: cause sudden death, sudden death is the most urgent state in clinic. It is manifested as sudden respiratory, cardiac arrest, loss of consciousness, and often within an hour of death. Hypertension is a high risk factor of sudden death because of the increase of left ventricular load, which leads to left ventricular hypertrophy, arrhythmia and coronary heart disease. Sudden death of coronary heart disease accounts for about 90% of all sudden death of cardiovascular disease.

matters needing attention

Hypertension can also lead to heart, brain, kidney and vascular diseases, left ventricular hypertrophy, congestive heart failure, aortic dissection, chronic renal failure and other serious life-threatening complications.
