Chronotherapy for coronary heart disease
Insights
Coronary heart disease events cluster by time of day. Addressing this "when-to" problem by understanding biologic time, not clock time, offers new therapeutic strategies for cardiovascular events.
Area of Science:
- Cardiology
- Chronobiology
- Internal Medicine
Background:
- Traditional coronary heart disease (CHD) therapy focuses on treatment methods.
- Cardiovascular events exhibit significant temporal clustering, suggesting a role for biologic timing.
- Understanding the
- when-to
- aspect of CHD is crucial for timely intervention.
Purpose of the Study:
- To address the
- when-to
- problem in coronary heart disease by investigating circadian variabilities.
- To propose a concept of biologic zero hours for accurate assessment of circadian rhythms.
- To recommend daily healthcare practices and chronotherapy for managing coronary risk factors.
Main Methods:
- Discussion of circadian variabilities in biology based on proposed biologic zero hours.
- Recommendation of daily healthcare practices aligned with circadian order for preventing acute coronary risk factors.
- Exploration of chronotherapy for chronic risk factors like hypertension, emphasizing individualized treatment.
Main Results:
- Circadian variabilities in CHD are linked to biologic time, necessitating a shift from mechanical clock-based assessments.
- A concept of biologic zero hours is introduced to better evaluate biological rhythms.
- Chronotherapy for hypertension involves customizing anti-hypertensive treatment based on individual blood pressure circadian variability.
Conclusions:
- Shifting focus from
- how-to
- to
- when-to
- in CHD therapy is essential.
- Biologic time, assessed via biologic zero hours, is key to understanding and managing cardiovascular events.
- Personalized chronotherapy, considering individual circadian blood pressure patterns, is vital for effective hypertension management.
Abstract:
Traditionally the therapy for coronary heart disease has been focused on the "how-to" problem. However, the clustering of cardiovascular events around the specific time of the day has been clarified. To solve the problems of the clustering would give us the clue to treat the coronary heart disease timely and in time. Therefore, the research has been stressed to solve "when-to" problem. The circadian variabilities in coronary heart disease has been clarified to be the function of the biologic time. Therefore, three problems were discussed in this paper. 1) The circadian variabilities in biology should be assessed based on the biologic zero hour rather than the mid-night of the mechanical clock. Our concept of the biologic zero hours has been proposed to answer this problem. 2) Daily health care with circadian order and harmony for the prevention of the coronary risk factors should be recommended as the prevention of the acute coronary risk factors as the trigger mechanism of the cardiovascular events. 3) The chronotherapy to chronic coronary risk factors such as hypertension was discussed, In hypertension the anti-hypertensive therapy should be customized individually adjusting the circadian variability of blood pressure with the proper selection of agents and time of the administration.
