Resistant hypertension is an intractable problem to patients and physicians. In recent decades, a substantial amount of basic and epidemiological studies provide us a vast number of valuable evidence and information about this once elusive disease. Better understanding about this entity could help physicians improve diagnostic and therapeutic accuracy. In present review, therefore, we first will detail the definition and diagnosis of resistant hypertension between cardiology societies, and followed by the information of prevalence of resistant hypertension around the world, and then briefly discuss currently used different nomenclature of resistant hypertension, and finally present diagnostic and therapeutic strategies of resistant hypertension.
