A significant research published in the journal Heart Asia this month had warned that the European and North American blood pressure guidelines - issued last year at 140/90 mmHg being the new normal - may actually increase the stroke risk if adapted for Asian patients, particularly the elderly.

"High blood pressure is a key risk factor for stroke, but the link between the two is much stronger in Asians than it is in Europeans or North Americans," the authors wrote.

"I agree that there has been a shift in the trend because of high sodium intake, lack of exercise, workplace stress and high levels of stress, but 120/80 is what one should aim to achieve," says Dr Manoj Kumar, associate director (department of cardiology) at Max Hospital in the capital.

According to a recent World Health Statistics report, 23.10 percent men and 22.60 percent women above 25 years suffer from hypertension in India. When your heart beats, it contracts and pushes blood through the arteries to the rest of the body. This force creates pressure on the arteries and is called systolic blood pressure (top reading). A normal systolic BP reading is 120 or a bit less.

"We currently recommend the western guidelines, specially JNC8, where 140/90 is the cut off value for diagnosing and initiating treatment of hypertension," Dr Neeraj Bhalla, director and senior consultant (cardiology) at BLK Superspecialty Hospitals, told IANS. The Eighth Joint National Committee (JNC8) in the US recently released evidence-based recommendations for the management of hypertension in adults.

According to these, treatment should be initiated when blood pressure is 150/90 mmHg or higher in adults 60 years and older, or 140/90 mmHg or higher in adults younger than 60 years.
Doctors also advise dietary approach to stop hypertension.

Daily recommendation for sodium intake is around 2.3 gram, potassium around 4.7 gram, calcium 1.25 gram and magnesium 500 mg.

"We should take at least 30 grams of fibres daily and cholesterol intake should be less than 150 mg. Nearly 30-45 minutes of moderate intensity exercise for five days a week is a sure bonus," Dr Bhalla points out.
