At what stage should we treat high blood pressure? The studies on the subject diverge. The results of an analysis, published in the Journal of the American Medical Association, indicate that treat arterial pressures systolic greater than 140 mm Hg can significantly reduce the risk of death and cardiovascular diseases.

The levels of blood pressure less than 140/80, the treatment brings no benefit in terms of prevention, but would protect him may be people with coronary artery disease. This work puts into question the objectives commonly accepted as well as the latest recommendations of the united states.

Very broad-based analysis

More than 300,000 people and 74 studies were taken into account in the analysis published in JAMA. The results show that for a systolic blood pressure of 160 mm Hg or more, treatment reduced the risk of death and cardiovascular disease. Between 140 and 159 mm Hg, the risk of death is reduced in the same proportion, but the reduction of cardiovascular events is less important. When the systolic blood pressure under 140 mm Hg, the treatment has no effect, neither on the decrease of mortality, nor on the decrease of cardiovascular events.

In the United States, a decrease objectives

Paradoxically, the United States, the thresholds were still lowered in the latest recommendations. The objective is increased from 140/90mm Hg to 130/80mm Hg, in agreement with the results of the study SPRINT. This increases the number of people considered to be in hypertension (+ 31.1 million people).

High blood pressure is the leading risk factor for death from cardiovascular disease.
