Hypertension is a common disease in clinical practice in many countries worldwide. There are currently about 1 billion people with hypertension, and it is estimated that by 2025, this number will reach 1.5 billion 1 . Hypertension is a deteriorative illness owing to its complications that damage target organs such as the heart, eyes, brain, and kidney, in which cardiovascular events are of particular concern. Many evidence show that arterial stiffness is an independent prognostic factor for predict-ting adverse cardiovascular outcomes in hypertensive patients 2 . The gold standard for determining arterial stiffness is to measure pulse wave velocity. Still, this method requires high-technology equipment, making it unavailable to be performed in some medical facilities, especially in the primary health care systems. Another method that correlates with the standard measurement is to evaluate by 24-hour ambulatory blood pressure monitoring. Although it is not a new method, it has adequacy of accessible opportunity, non-invasive feature, and does not require high-technical equipment. As a result, this
