American Heart Association and the American College of Cardiology have introduced new rules and therefore are responsible for the change in definition of high blood pressure and hypertension. Precursory rules that have been utilized for innumerable years defined high blood pressure as 140/90 millimeters of mercury or greater. But according to the new rules, high blood pressure is 130/80 or greater.
The premiere number is called the systolic pressure, narrating the constraint on blood vessels when the heart takes a beat, and the secondary is called as the diastolic pressure when the heart unwinds. This indicates to the fact that now tens of millions more Americans will now be communicated when they get their blood pressure checked that they have hypertension. It will be approximated that with this alteration the number of men under the age of 45 will have high blood pressure will triple and number of women under age 45 will double.
The earlier revisions made as far as hypertension is concerned was in 2003. The criteria for changing the norm was increasing proof that blood pressure much lesser that had been contemplated vastly minimizes the probability of heart attack and stroke as well as risk of death.
A massive federal study called SPRINT showcased that lessening blood pressure standards from 140/90 to 130/80 could enhance the battle against cardiovascular disease assisting to lessen the risk of death. The present number of Americans possessing high blood pressure is 72 million. But with alteration in the guidelines this number is going to rise to 103 million.
