Arterial hypertension is the most important public health problem in Croatia, and its role as the main risk factor for cardiovascular, brain and kidney diseases is still not recognised enough. In order to increase awareness about the importance of this issue and to improve control in treated individuals with arterial hypertension, a program entitled “Mission 70/26” has been initiated with the goal of achieving target values in 70% of treated patients with arterial hypertension by 2026, which would significantly decrease the overall cardiovascular, cerebrovascular, and renal morbidity and mortality in Croatia. This mission is part of the permanent campaign of the Croatian Hypertension League called “The Hunt for the Silent Killer”.
