[Relationship between Circadian Rhythm Disorder of Blood Pressure and Ischemic Stroke]

Area of Science:

• Cardiovascular Science
• Neurology
• Sleep Medicine

Background:

• Hypertension is a known risk factor for stroke.
• The link between hypertension and stroke is primarily understood at the overall blood pressure level.
• Disruptions in the body's natural daily blood pressure patterns (circadian rhythm) are increasingly recognized as significant.

Purpose of the Study:

• To review the concept of blood pressure circadian rhythm.
• To classify different types of blood pressure circadian rhythm disorders.
• To examine the association between these disorders and ischemic stroke.

Main Methods:

• Literature review of existing research on blood pressure circadian rhythms and stroke.
• Analysis of studies classifying circadian rhythm disorders.
• Synthesis of evidence linking rhythm abnormalities to ischemic stroke pathogenesis.

Main Results:

• The review defines blood pressure circadian rhythm and its normal patterns.
• It categorizes common circadian rhythm disorders, such as non-dipping and reverse-dipping.
• Evidence suggests a correlation between disrupted blood pressure rhythms and increased risk of ischemic stroke.

Conclusions:

• Circadian rhythm of blood pressure is crucial in stroke development.
• Blood pressure circadian rhythm disorders represent a significant, underappreciated factor in ischemic stroke.
• Further research into managing these rhythm disturbances may offer new stroke prevention strategies.
