The strength of this pushing is your blood pressure. If your blood pressure is too high, it puts extra strain on your arteries (and your heart) and this may lead to heart attacks and strokes. Systemic Arterial Pressure: The risk of cardiovascular disease increases progressively above 115/75 mmHg.[7] In practice blood pressure is considered too low only if noticeable symptoms are present.[4] Observational studies demonstrate that people who maintain arterial pressures at the low end of these pressure ranges have much better long term cardiovascular health. There is an ongoing medical debate over what is the optimal level of blood pressure to target when using drugs to lower blood pressure with hypertension, particularly in older people.[8] The table shows the classification of blood pressure adopted by the Amer...
