The American Heart Association (AHA) has devised new blood pressure guidelines.  In this iteration, the AHA tell us that any blood pressure over 120 is dangerous and must be treated, with pressures over 180 requiring immediate hospitalization.  There is no age cut off, and no accounting for individual variability. That the AHA is highly dependent on Big Pharma for its financial coffers, and has on its leadership many ex executives of Big Pharma, likely helped trigger there anti-scientific and dangerous recommendations.  In fact, only one flawed study supports their recommendations, while dozens of others refute them.  We will discuss this through the lens of science and common sense, and we'll demonstrate why guidelines are often worrisome, and how these recommendations demonstrate the power of Big Pharma over medical care.
