Distribution of risk factors in relation to the presence of cerebral angiographic lesions in TIA and minor stroke patients.
In a series of patients with TIA or minor stroke we have investigated the possibility of a different distribution of risk factors according to the presence or absence of angiographic lesions of the cerebral arterial circulation. The differences observed, though not statistically significant, argue for a more severe and widespread atherosclerotic process in patients with positive angiography. A significant proportion of these patients present associated insufficiency of the coronary circulation, demonstrated indirectly by exercise testing. The exercise test presents a positive predictive power of 41% for cerebral angiographic lesions.
