Hypertension is divided into three degrees of severity, depending on the parameters of blood pressure.
Grade I: 140-159/90-99 mmHg Grade II: 160-179/100-109 mm Hg Grade III: 180/110 mm Hg
Recall that the normal values of blood pressure is 120-129/80-84 mmHg pregipertenziya characterized by BP levels 130-139/85-89 mmHg
Hypertension in the elderly is a more significant risk factor for complications than at a young age. Note that when I hypertension severity in people aged 25-35 years the risk of complications in the cardiovascular system is less than 11% within 10 years. The risk in people of older age (55-74 years), it exceeds 30%.
In addition, a positive correlation between the level of blood pressure and total mortality: the lower the systolic or diastolic blood pressure (regardless of a person's age), the lower the mortality rate, and vice versa. When the blood pressure values for each 10 mmHg also increases the risk of complications in the cardiovascular system, approximately 10%.
