HYPERTENSION

04 Jul 2020 | 3 mins

When there is an increase in systolic or diastolic blood pressure or both, we call it hypertension. Usually, normal blood pressure is 120/80 or below. Conventionally a blood pressure of 140/90 is the upper limit of normal BP. 

ACC – AHA (American College of Cardiology – American Heart Association) classification of hypertension is as follows.

Normal: Systolic <120, Diastolic <80 mm Hg
Elevated: Systolic 120 - 129, Diastolic 80 mm Hg
Hypertension:

Stage I Systolic: 130 – 139, Diastolic 80 – 89 mm Hg
Stage II Systolic: >140, Diastolic >90 mm Hg

Hypertension is a risk factor for stroke, accelerated coronary and systemic atherosclerosis, heart failure, chronic kidney diseases, and death from cardiovascular causes.

How to take blood pressure?
At least 2 BP measurements with the use of a standardized measurement technique with a cuff of the correct size. Measurements should be made with the back supported, legs uncrossed, feet on the floor and the measuring arm supported on a table at heart level after the patient has sat quietly for 5 minutes.

1. Lifestyle modifications
2. Restrict salt (sodium) below 1500 mg/ day
3. If overweight or obese, reduce weight

6. Avoid smoking
7. Reduce alcohol use

Drugs
