Key result
Pathological CAVI (>9.0) was present in 45.4% of post-stroke patients and was associated with higher rates of diabetes, peripheral atherosclerosis, heart failure, and atrial fibrillation.
Why the study?
Does the cardio-ankle vascular index (CAVI) correlate with clinical risk factors and cardiovascular comorbidities in post-stroke patients?
Observational (n=374)
Does the cardio-ankle vascular index (CAVI) correlate with clinical risk factors and cardiovascular comorbidities in post-stroke patients?
Assessment of CAVI and ASI in ischemic stroke patients helps identify those with increased vascular rigidity and peripheral atherosclerosis, highlighting a higher burden of cardiovascular comorbidities.
CAVI assessment in stroke survivors is hypothesis-generating; prospective studies needed before any clinical adoption.
AIM: To study the clinical significance of the cardio-ankle vascular index (CAVI) in patients with stroke. MATERIAL AND METHODS: The study included 374 post-stroke patients. The state of peripheral arteries was assessed using CAVI and the ankle-shoulder index (ASI). RESULTS AND CONCLUSION: The pathological CAVI (>9.0) was identified in 45.4% patients, the reduced ASI (<0.9) in 19.8% patients. Stressful factors of daily life, hypodynamia, lack of work, low education were characteristic of the patients with pathological CAVI and ASI compared to those with normal CAVI. The frequency of diabetes mellitus, clinical signs of peripheral atherosclerosis, chronic heart failure and atrial fibrillation was higher in these patients as well. Ischemic stroke was more frequent in patients with peripheral atherosclerosis and higher vascular wall rigidity. Assessments of CAVI and ASI are necessary in patients with ischemic stroke to identify those with higher vascular wall rigidity and peripheral atherosclerosis and to undertake targeted preventive measures.

Сумин et al. (2016) conducted an observational in Stroke (n=374). Cardio-ankle vascular index (CAVI) vs. Normal CAVI was evaluated on Pathological CAVI (>9.0). Pathological CAVI (>9.0) was present in 45.4% of post-stroke patients and was associated with higher rates of diabetes, peripheral atherosclerosis, heart failure, and atrial fibrillation.
