Early vascular aging in acute ischemic stroke: A systematic review and meta-analysis.

Background: While arterial stiffening is a known risk factor for cardiovascular diseases, it remains unclear whether there is an early vascular aging (EVA) in patients who have experienced acute ischemic stroke (AIS). This systematic review and meta-analysis aims to investigate whether patients with AIS exhibit EVA through pulse wave velocity (PWV) measurements shortly after the stroke onset, shedding light on the relationship between arterial stiffness, hypertension, and stroke.
Methods: Thirteen case-control studies were included, comparing PWV measurements between AIS patients and non-AIS individuals. A meta-analysis was performed to compare PWV levels, age, blood pressure, and the prevalence of different cardiovascular risk factors among 1711 AIS patients and 1551 controls.
Results: Despite AIS patients showing higher PWV compared to controls (mean difference: 1.72 m/s, 95 % CI: 1.05-2.38, p < 0.001; I ² = 88.3 %), their age did not significantly differ (95 % CI: -0.47-0.94, p = 0.519; I ^{2 =} 0 %), suggesting EVA in AIS patients. Moreover, AIS patients exhibited elevated systolic and diastolic blood pressure and had higher odds of smoking, hypertension, diabetes, and male gender compared to controls.
Conclusions: This study's findings underscore the presence of EVA in AIS patients, evident through increased PWV measurements shortly after stroke onset. Notably, smoking, hypertension, and diabetes mellitus emerge as substantial factors contributing to accelerated arterial stiffness within this population.
