Insights
Small vessel disease (SVD) and large artery atherosclerosis (LAA) frequently coexist in stroke patients with aortic plaques. This highlights the link between macro- and microvascular disease, especially with significant atherosclerosis risk factors.
Area of Science:
- Neurology
- Cardiovascular Medicine
- Radiology
Background:
- Large artery atherosclerosis (LAA) and small vessel disease (SVD) are common contributors to stroke.
- These conditions share underlying risk factors, suggesting a potential link.
Purpose of the Study:
- To investigate the association between SVD and cerebral LAA.
- To examine the relationship between SVD and aortic atherosclerosis in stroke patients.
Main Methods:
- A study of 71 ischemic stroke patients with undetermined cause.
- ECG-triggered CT angiography was used for atherosclerotic plaque detection in the aorta.
Main Results:
- Aortic atherosclerotic plaques were found in 76.1% of patients.
- SVD presence significantly correlated with aortic plaques (p < 0.001) and LAA (p < 0.001).
- SVD also correlated with hypertension (p = 0.032) and diabetes mellitus (p = 0.017).
Conclusions:
- Aortic plaques are prevalent in stroke patients of undetermined origin.
- SVD and LAA often coexist, indicating a link between micro- and macroangiopathy.
- This association is particularly evident in patients with severe atherosclerosis risk factors.
Background And Purpose:
Large artery atherosclerosis (LAA) and small vessel disease (SVD) share common risk factors for stroke. We aimed at investigating the association of SVD with cerebral LAA as well as with atherosclerosis in patients with stroke likely to originate from aortic plaques.
Methods:
We investigated 71 consecutive patients (48 men, mean age 64.2 ± 13 years) with ischemic stroke of undetermined cause according to the ASCO classification, who received ECG-triggered CT angiography for best available atherosclerotic plaque detection in the aorta.
Results:
Aortic atherosclerotic plaques were detected in 54 patients (76.1%). The presence of SVD significantly correlated with the presence of aortic plaques (p < 0.001), as well as LAA (p < 0.001) and risk factors such as arterial hypertension (p = 0.032) and diabetes mellitus (p = 0.017).
Conclusions:
Aortic plaques are common in patients with stroke of undetermined cause. If so, SVD and LAA are often coexisting, which demonstrates the close link of macro- and microangiopathy, at least in cases of severe risk factors of atherosclerosis.

Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and narrowing...
