The long lasting medical heart condition in which normal arterial blood pressure is increased is called high blood pressure or hypertension. It’s antagonistic to hypotension and it is further classified into two classes which are primary hypertension and secondary hypertension. In a population about 905 cases are of primary hypertension in which there is no specific medical cause behind the occurrence of hypertension while 5-105 cases are of secondary hypertension in which the main cause of hypertension is disorders of kidneys, arteries, heart or endocrine system.
High blood pressure lasting for a long time can be a reason of stroke, myocardial infarction, heart failure, arterial aneurysm and even chronic kidney failure. Even moderate type of hypertension can reduce life expectancy in the patient and changes in diet and life style can help a lot in controlling the high blood pressure along with decrease in the risk of health problems but there are some patients in which high blood pressure can only be treated by using certain medications.
Classification:
High systolic or diastolic blood pressure then normal blood pressure is classified as high blood pressure or hypertension. There are different stages of hypertension which are as follow:
Hypertension stage l
Hypertension stage II
Isolated hypertension
The last stage represents the high systolic blood pressure and it is evident in elders mostly. These three stages of high blood pressure are made on the basis of ranges of blood pressure in the patient. In people more then 50 years of age the range of high blood pressure starts from 140 mmHg systolic and 90 mmHg diastolic blood pressure.
Exercise hypertension is the type of hypertension which is only experienced during exercise. The normal range of systolic blood pressure is 200 – 300 mmHg.
