The extreme dipping pattern,a common diurnal blood pressure variation,has been observed in both general and hypertensive populations.However,there is a relatively limited and inconclusive academic focus on this blood pressure pattern.The reported prevalence of the extreme dipping pattern varies significantly,correlating with diagnostic criteria and participant characteristics.While the majority of studies have not firmly established the relationship between the extreme dipping pattern and target organ damage,it shows correlation with major adverse cardiovascular events.This paper aims to provide a comprehensive review of the academic understanding and research advancements regarding the extreme dipping pattern in blood pressure.
