The significance of ambulatory blood pressure monitoring for evaluating circadian blood pressure variations affected by alcohol consumption.

Possible diurnal blood pressure variation change due to alcohol consumption. • Normally, blood pressure declines by around 10-20% at night compared to daytime (nocturnal decline, orange line). • In the acute phase of alcohol consumption, blood pressure declines from the original blue line due to vasodilation caused by alcohol and then increases (orange arrow, and brown line). • However, with long-term alcohol consumption, there is a sustained rise in blood pressure (red arrow), and eventually, blood pressure at night is also higher than that in non-drinkers (red line).
