New clinical study conducted in the U.S. showed that lowering high blood pressure as low as possible may not have any significant impact on preventing heat attack as scientists thought it had.

The research included 4.480 participants and lasted for 21 years. Patients were followed during this period in order to discover whether these hypertension patents developed any type of heart condition or disease. The research was particularly focused on measuring systolic blood pressure of SBP, which is actually the higher number we get in standard blood pressure measuring.
Researchers in the study considered that SBP reading 140 or higher to be high, readings between 120 and 139 to be normal and below 120 to be low. What the study revealed was that in patients with hypertension, reducing of the SBP to below 120 had no particular impact on preventing heart failure, heart attack and stroke risks. What the study did show it that lowering blood pressure below 140 did have significant benefit.
These results are surely interesting and partially go against what we know about high blood pressure and high blood pressure treatment. The American Heart Association still sticks to the conventional information, that is, that lowering of the blood pressure below 120 is the best therapy providing the best results.
One of the researchers of the study, Dr. Rodriguez says that the study showed that the greatest clinical effects and benefits appear when lowering high blood pressure below 140. Since this was not a treatment studies, many additional studies will be needed to confirm or dispute the results of the study we looked at today.
