Background: A significant but yet manageable risk factor for cardiovascular disease is hypertension. Increased mortality and morbidity are linked to it. Accurate blood pressure measurement is necessary for the early diagnosis of hypertension and the prevention of its consequences blood pressure (BP). The reading of blood pressure is typically identical in each arm. However, the term "inter-arm difference" refers to the natural occurrence of a reading disparity between the two arms Inter-arm blood pressure difference (IAD). Objective: Toevaluate the incidence of different blood pressure between the two arms and todetermine the connection between variations in interarm blood pressure and left ventricle (LV) systolic and diastolic parameters. Conclusion: Since monitoring BP is a straightforward but vital factor in identifying the population most at risk for future vascular events, particularly in HTN patients who appear to have control of their condition, learning It is crucial to know how common IAD is among adults.
