“Several population-based studies have demonstrated that SBP levels currently considered normal (<130 mmHg) are not safe, and in fact, there is a graded increase in CVD risk as SBP increases beyond 90 mmHg.4–7 Whelton et al .6 found that the amount of coronary artery calcium and the risk of incident atherosclerotic CVD increase with increasing SBP levels, even in individuals with SBP 90–120 mmHg. In fact, mounting evidence has made it abundantly clear that so-called high normal BP levels (120–129 mmHg) are associated with a significant increase in incident CVD compared with SBP levels of 90–100 mmHg. This connection may be much more pronounced in yet to be identified subgroups. This means that CVD risk starts even when SBP is a long way below 130/80 mmHg, which is the current threshold used to diagnose and define hypertension.8 Therefore, the guideline-based definition of normal BP does not provide freedom from CVD risk. Without a doubt, SBP of 120–130 mmHg is a harbinger of significant chronic disease burden and portends a poor prognosis. Overall, CVD risk appears to be independently associated with SBP levels, starting at 90 mmHg.“
