Background: Blood pressure can be monitored during regular activities like resting and light to moderate activity using ambulatory blood pressure monitoring (ABPM). The majority of the most current major hypertension guidelines suggest using it as a blood pressure measurement technique at home. Numerous studies now available demonstrate that when it comes to monitoring blood pressure and forecasting the risk and occurrence of cardiovascular (CV) events, ABPM is more accurate than office blood pressure disease. Many studies have shown that ambulatory blood pressure especially at night is a more reliable indicator of cardiovascular issues and overall mortality than office blood pressure. By cross-classifying patients according to their office and ambulatory blood pressure readings, it is possible to differentiate between those with white-coat hypertension and those with persistent hypertension, as well as between those with masked hypertension and normotension. White-coat hypertension was not associated with high CV risk, whereas concealed and chronic hypertension were. This review article's goal is to assess ambulatory blood pressure monitoring's utility. Conclusions: ABPM is acknowledged as a crucial component of excellent clinical practice in the field and plays a significant role in the diagnosis and treatment of hypertension. This is the only method of blood pressure monitoring available outside of an office that can give data on the 24-hour blood pressure profile, which includes nocturnal hypertension, morning blood pressure rise, and BPV. These factors are all significant indicators of TOD as well as cardiovascular and cerebrovascular risk.
