The reduction in early morning blood pressure compared with average daytime pressure is referred to as the night-time dip. Ambulatory blood pressure monitoring may reveal a blunted or abolished overnight dip in blood pressure. This is clinically useful information because non-dipping blood pressure is associated with a higher risk of left ventricle hypertrophy and cardiovascular mortality.
The difference between early morning blood pressure and average daytime levels is known as the night-time dip. Ambulatory monitoring can reveal a reduced or absent overnight drop in blood pressure, which correlates with increased risk of heart problems like left ventricular hypertrophy and higher chances of death from cardiovascular issues.
