Circadian rhythms in cardiovascular (dys)function: approaches for future therapeutics

Area of Science:

• Cardiovascular Physiology
• Chronobiology
• Internal Medicine

Background:

• The circadian clock regulates 24-hour physiological processes, including cardiovascular parameters like blood pressure and heart rate.
• Disruptions to circadian rhythms are linked to cardiovascular diseases such as hypertension and myocardial infarction.
• Key cardiovascular disease risk factors like obesity, sleep disorders, and aging can impact circadian clock function.

Purpose of the Study:

• To review the impact of circadian rhythms on human cardiovascular health.
• To examine how circadian clock disruption contributes to adverse cardiac events.
• To discuss the interplay between cardiovascular disease risk factors and circadian rhythms.

Main Methods:

• Literature review of studies on circadian rhythms and cardiovascular health.
• Analysis of research linking circadian disruption to cardiac events.
• Exploration of chronotherapy and clock-targeting strategies.

Main Results:

• Circadian rhythmicity is integral to cardiovascular function.
• Chronic disruption of diurnal rhythms elevates the risk of hypertension, arrhythmias, and myocardial infarction.
• Cardiovascular disease risk factors can negatively affect the circadian clock.

Conclusions:

• Circadian clock disruption poses a significant threat to cardiovascular health.
• Targeting the circadian clock and implementing chronotherapy are promising clinical strategies.
• Translating circadian science into clinical practice can improve cardiovascular disease prevention and treatment.
