Since 2012, doctors encountered a tsunami of new guidelines in the field of hypertension. >8 guidelines have been published by different societies or groups, causing confusion not only among general practitioners, but also among experts. However, if we look into the literature, no new drugs for the treatment of blood pressure (BP) have been released and only a few randomized clinical trials have taken place, which leads to the conclusion that all the data being used in these guidelines are coming from these randomized clinical trials, post-hoc analyses of large outcome trials, registries, as well as meta-analyses clinical trials.
