Factors related to degree of peripheral arterial occlusive disease in acute stroke patients (by toe-brachial index)

Background
A low ankle-brachial index (ABI) is associated with an increased risk of peripheral artery disease, cardiovascular disease and stroke. Recently, the toe-brachial index (TBI) has been receiving attention for non-invasive method for measurement of atherosclerosis which is generally regarded as a risk factor for stroke. Limited data exist regarding the relation between a low TBI and stroke. In this study, we investigated the relation between a low TBI and stroke.

Method
We reviewed Ilsan Hospital stroke database of recent 3 years. Total 50 acute cerebral infarction patients with completed stroke database and TBI study was included. The relationship with TBI, TOAST classification, risk factors of stroke and degree of cerebral artery stenosis was investigated.

Results
According to degree of TBI, peripheral arterial occlusive disease (PAOD) was classified as normal (TBI > 0.9), moderate (0.6 < TBI < 0.9) and severe (TBI < 0.6). Moderate and severe PAOD was more common in large artery atherosclerosis (LAA) patients than small vessel occlusion (SVO) and cardioembolism (CE) patients between subgroups by TOAST classification. PAOD was not significantly correlated with the number of stenotic vessels by the transcranial Doppler study(TCD).

Conclusion
Toe brachial index can be a useful marker which reflect the degree of peripheral atherosclerosis in stroke patients. PAOD was more common and severe in large artery atherosclerosis patients among cerebral infarction patients.
