Studies have shown that people with high blood pressure (140/90) or high normal blood pressure (130-139/85-89) are 2-3 times more at risk of developing heart disease as compared to those with optimal (120/80) or normal blood pressure (120-129/80-84). In fact, they are more likely to have a heart attack, heart failure or a stroke (lack of oxygen in brain leading to paralysis) in the next 10 years!
The studies also found that the incidence of developing heart complaints was more in women as compared to men.
Hence, it is very important for people with high normal blood pressure to maintain their blood pressure at optimal levels. It still needs to be known whether these people require any aggressive therapy such as medications. However, current guidelines suggest that blood pressure can be controlled at optimal levels by certain modifications in diet and lifestyle. One may also consider consulting a doctor for drawing out a regular exercise regimen.
