Key result
Carotid circumferential strain (1.46% vs 2.75%; P=0.002) and strain rate were significantly lower in elderly individuals with a history of ischemic stroke compared to those without.
Why the study?
Is carotid arterial stiffness measured by speckle tracking echocardiography associated with previous ischemic stroke in the elderly?

Reduced carotid strain was associated with prior ischemic stroke; hypothesis-generating and should not yet change practice.

Is carotid arterial stiffness measured by speckle tracking echocardiography associated with previous ischemic stroke in the elderly?
Absolute Event Rate: 1.46% vs 2.75%
p-value: p=0.002
Carotid wall deformation indices (circumferential strain and strain rate) measured by speckle tracking are independently associated with previous ischemic stroke in the elderly.
Tsai et al. (2013) conducted a cross-sectional in Ischemic stroke (n=89). History of ischemic stroke vs. No history of ischemic stroke was evaluated on Carotid circumferential strain (CS) (p=0.002). Carotid circumferential strain (1.46% vs 2.75%; P=0.002) and strain rate were significantly lower in elderly individuals with a history of ischemic stroke compared to those without.
