Insights
Thoracic aorta calcification (TAC) strongly predicts mortality and cardiovascular events. This finding highlights TAC as a crucial indicator for assessing patient risk across diverse clinical scenarios.
Area of Science:
- Cardiology
- Radiology
- Public Health
Background:
- Thoracic aorta calcification (TAC) is increasingly recognized in cardiovascular risk assessment.
- Understanding TAC's prognostic value across different imaging modalities and clinical settings is essential.
Purpose of the Study:
- To systematically review and assess thoracic aorta calcification (TAC) as a predictor of all-cause mortality and cardiovascular (CV) morbidity/mortality.
- To evaluate the impact of different imaging modalities on TAC's predictive power.
Main Methods:
- Systematic literature search of medical databases up to mid-July 2025.
- Inclusion of 43 studies with 176,738 participants linking TAC to mortality and CV outcomes.
- Meta-analysis of hazard ratios (HR) for various outcomes.
Main Results:
- TAC significantly increases risks for all-cause mortality (HR=1.614), CV mortality (HR=2.130), coronary events (HR=1.423), major adverse cardiac events (HR=2.011), and stroke (HR=1.450).
- Computed tomography demonstrated the strongest associations (e.g., CV mortality HR=2.641).
- Elevated mortality risk was observed across all aortic segments.
Conclusions:
- Thoracic aorta calcification is a robust predictor of all-cause mortality, coronary events, and CV morbidity/mortality.
- TAC assessment aids in risk stratification across various clinical contexts.
- Imaging modality influences the strength of TAC's association with adverse outcomes.
Abstract:
This review aimed to assess thoracic aorta calcification (TAC) as a predictor of all-cause mortality, cardiovascular (CV) morbidity and mortality across various clinical settings using different imaging modalities. Medical databases were systematically searched up to mid-July 2025 for studies linking TAC with mortality and CV outcomes. A total of 43 studies involving 176,738 participants were included. TAC was associated with higher risks of all-cause mortality (hazard ratio [HR] = 1.614), CV mortality (HR = 2.130), coronary events (HR = 1.423), major adverse cardiac events (HR = 2.011) and stroke (HR = 1.450. Computed tomography showed the strongest associations (all-cause mortality HR = 1.810; CV mortality HR = 2.641), followed by chest radiography and echocardiography. Mortality risk was elevated across all aortic segments, including descending aorta (HR = 1.414), aortic arch (HR = 1.362), ascending aorta (HR = 1.350) and aortic root (HR = 1.240). TAC is a strong predictor of all-cause mortality, coronary events, CV mortality and morbidity.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
