What are the indications of Ambulatory Blood Pressure Monitoring? (ABPM)

• Suspected White coat hypertension 
• Drug resistant hypertension
• Drug induced hypertension
• Episodic/Paroxysmal hypertension
• Autonomic dysfunction

During sleep BP falls by 10-20%. If it doesnot fall by 10-20% during night, it suggests an increased risk of cardiovascular events

If 24 hrs BP exceeds 135/85 mmHg, the risk of CV events is twice as compared to those with 24hr BP < 135/85
