Heart & Cardiology/Higher BP More Dangerous At Night

Question
CV Risk Ambulatory BP
CV Risk Ambulatory BP  
Hello Dr Ahmed,

Belated Happy New Year Greetings to you.

Does the attached graph indicate elevated BP at night is the most dangerous?  And that elevated BP in the clinic is the "safest"?

Does it mean that for a given elevated BP status, the odds of dying in one's sleep are higher than dying during the daytime?

The screenshot is taken from the 2005 paper in hypertension (Eamon Dolan et al "Superiority of Ambulatory Over Clinic Blood Pressure Measurement in Predicting Mortality - The Dublin Outcome Study"
Hypertension 2005;46:156-161), link below.

Thanks!

Best regards,

Answer
Hi,
The graph means that night time blood pressure is the most predictive of long term poor outcome. Compared to that clinic elevated blood pressure is better, but the bottom line is elevated clinic blood pressure is worse than no blood pressure at all. The paper did not collect data on timing of death so theres no way to tell of odds of dying in sleep.

Hope that was helpful.
