Aortic aneurysm (AA) incidence peaks in the morning and colder months, mirroring other cardiovascular events. Understanding these chronobiological patterns is key for developing new prevention strategies.
Area of Science:
- Chronobiology
- Cardiovascular Pathophysiology
- Atherosclerosis
Background:
- Aortic aneurysm (AA) is a significant cause of mortality, often resulting from atherosclerosis or genetic disorders.
- AAs are frequently asymptomatic until rupture, which has a high fatality rate.
- AA incidence may follow chronobiological patterns, similar to other cardiovascular diseases.
Purpose of the Study:
- To evaluate the association between circadian rhythms, seasonal variations, and genetic factors in AA pathogenesis.
- To review the impact of chronobiology on aortic aneurysm development and incidence.
Main Methods:
- Comprehensive literature review.
- Analysis of existing studies on chronobiology and aortic aneurysms.
Main Results:
- AA incidence peaks in the early morning (6-11 a.m.) and during colder months.
- AA incidence troughs in the evening and warmer months.
- These patterns resemble those observed in myocardial infarcts and cerebrovascular strokes.
Conclusions:
- A clear link exists between chronobiology and the incidence/pathogenesis of ruptured AA.
- The association is more pronounced in individuals with Marfan syndrome or vitamin D deficiency.
- Further research into chronotherapeutics is needed for precision medicine approaches to AA prevention.
