PREVENTION AND CONTROL OF HIGH BLOOD PRESSURE

Definition of hypertensin.

Hypertension or high blood pressure means raised arterial blood pressure above normal. It is a symptom and not a disease. It is one of the variety of disorders like kidney failure, lead poisoning, toxaemia of pregnancy, rough of aorta, etc. but in the most of the cases, causes is not known.

Varieties of hypertension.

Hypertension or hypertensive disease when accompanied with clinical manifestations of blood pressure, the condition is said as hypertention or hypertensive disease. Hypertensive heart disease means if the cardiac function is disturbed or myocardiu is involved. If the blood pressure is due to renal disease or any other condition is known as secondary hypertension, or other wise any other condition of blood pressure raises,it known as primary or esential hypertension. Primary hypertensive disease progress soon to heart enlagement and failure and also towards a fatal end, it is called malignant hypertension.It will vary above 180/120 mm of hg and patient should be admitted to hospital for reducing blood pressure to avoid damage of organs like kidney, heart,liver, etc.PAH means pulmonary arterial hypertension.  which can be diagnosed through ecko cardiogram. To find out the gradation of conditions are give below.
1. Ascertain BP at variuos times during day, while resting in bed and when uder treatment with antihypertensive medicines. Find any primary cause like kidney dieases, diabetes, pregnancy or albumen in blood. Finding out any change in heart functions, pulse rate, electro-cardiographic changes, etc. And also ascertain secondary hypertensive complaints such as blood in urine, albumen, and disturbed kidney functions.
2. Hypertension is a socio-medical problem due to its high incidence with hypertensive heart diseases. It is increasing in the world with modern living conditions such as industrailisation, etc, high morbidity and mortality involving disability and economic loss.Next to heart disease and cerebral disease, it has the highest mortality rate.out of over the one fifth of all deaths over the age of 50. Above 30 percentage of population over 50 years of age may be suffering from it. Malignant forms of this disease are less common in eastern than western countries.
3. When hypertension is found out to a specific primary condition, some of the following factors believed to be responsible in the causation of high blood presure,is known as hypertensive risk factor like overweight and obesity,smoking,genetic factors,etc. Salt restriction brings down high blood presure levels,but if an excessive salt intake raises normal blood presure or not and if so whether it is one of the causes of persistant hypertension,is not known.

Preventive and control measures of hypertension.

Detection and treatment of early cases is an important measure due to even established hypertension may remain uncompliated for long time. Early,mild and uncomplicated high blood pressure with a view of arresting further progression of the disease and to increase long life under the category of secondary prevention of essential primary hypertension.By the care of certain factors like mode of life, habits, diet and body weight and treatment of antihypertensive medicines and psychotherapy,it is possible to obtain partial or complete cure in such cases towards longer and healthier lives so that the passive attitude based on high blood pressure is incurable. Certain secondary hypertensions are primarily preventable.Corrective surgery  in early childwood for coarctation, early intensive treatment of urinary infections,prevention and early treatment for throat infections in children, quick detection and removal of adrenal tumour, efficient antenatal or prenatal care for detection and treatment of the toxaemia arrest for the development of secondary hypertension. The object of prevention and control of hypertension should be to get rid of, arrest, undo or impede the progress of
the primary and secodary hypertensive disease in its early and late stages with complications. Other measures are the treatment of advanced cases and rehabilitation of the affected persons and health education of public,etc.The preventive approach to hypertension was grasped and professed long back in 1876 Handfield Jones when he said 'If I were bold enough to be a prophet, I should point to the time when the elder folks,instead of waiting till they had a stroke of apoplexy or a touch of paralysis....and then hurriedly summoning a physician to do impossibilities, will seek his advice, asking him to supervise their vital functions, regulate their mode of life and teach them to stay the morbid changes which they know may be silently progressing'
