Background: Patients with acute ischemic stroke have higher aortic stiffness estimated by carotid-femoral pulse wave velocity (CF-PWV) and central augmentation index (cAIx) than control hypertensives. Whether CF-PWV and cAIx may distinguish patients with first-ever (FES) from those with recurrent ischemic stroke (RS) is unknown.
The aim of the study was to evaluate CF-PWV and cAIx in patients with the FES and RS as compared to control hypertensives, and to evaluate the relationship between these indexes and other clinical variables.
Methods: We studied 113 patients (82 males, 62.9±12.7yrs) with acute ischemic stroke, including 17 subjects with RS (13 males, 67.6±10.8yrs) and 71 controls (52 males, age 62.7±12.6yrs).CF-PWV, and cAIx were measured (SphygmoCor®) one week after stroke onset. Data were analysed with multivariate analysis.
Results: The mean CF-PWV was significantly higher in both RS and FES than in controls (12.5±3.5 vs. 8.6±1.3m/s, P<0.00001, and 10.2±2.8 vs. 8.6±1.3m/s, P=0.004 respectively). Moreover, the mean CF-PWV was significantly higher in RS compared to FES (12.5±3.5 vs. 10.0±2.8m/s, P=0.01). cAIx in RS (32.3±14.3mmHg) was similar to that in FES (28.5±11.7mmHg, P=0.49), but it was significantly higher compared to controls (25.2±10.3mmHg, P=0.02). In multivariate logistic regression analysis, higher CF-PWV remained significant after adjustment for age, SBP or HR, separately (Table).
Model | OR | 95% CI | P value |
---|---|---|---|
Model 1 (R2=0.02) | |||
Age | 1.01 | 0.96 – 1.07 | 0.65 |
CF-PWV | 1.23 | 1.01 – 1.50 | 0.04 |
Model 2 (R2=0.12) | |||
SBP | 0.97 | 0.93 – 1.01 | 0.1 |
CF-PWV | 1.45 | 1.12 – 1.89 | 0.005 |
Model 3 (R2=0.08) | |||
HR | 1.01 | 0.96 – 1.06 | 0.75 |
CF-PWV | 1.24 | 1.04 – 1.47 | 0.02 |
Conclusion: CF-PWV is higher in patients with recurrent stroke than in those with first-ever event independently of age and BP levels. These findings suggest that aortic stiffness might be implicated in progression of cerebrovascular disease in post-stroke patients.
