A person with pre-hypertension, systolic blood pressure between 120-139 mmHg and diastolic pressure between 80-89 mmHg, is more than three times likely to have a heart attack and 1.7 times more likely to have heart disease than a person whose blood pressure is lower than 120/80 mmHg.
SYSTOLIC BLOOD pressure is the pressure against the artery wall when the heart beats and diastolic blood pressure is the pressure when the heart is at rest between the heart beats. Normal blood pressure is lower than 120/80 mmHg and hypertension is a blood pressure more than 140/90 mmHg or higher.
Research has shown that if prehypertension is aggressively treated, 45% of all heart attacks can be prevented. Lifestyle modifications such as weight control, regular physical activity and changes in diet are recommended for people with pre–hypertension.
The importance of prehypertension has been listed as one of the top 10 recent advances in cardiology. Every effort should be made to lower the blood pressure below 120/80 mmHg.
