BACKGROUND: Considerable researches suggest that high level of homocysteine (Hcy) is associated with the risk of ischemic stroke. Ambulatory blood pressure monitoring (ABPM) parameters have also been confirmed associated with cardio-cerebrovascular events. However, the relationship between Hcy and ABPM parameters remains unclear in patients with acute ischemic stroke. In this study, we aim to investigate the association between Hcy level and ABPM parameters in patients with acute ischemic stroke.
METHODS: We enrolled 60 patients with acute ischemic stroke who received ABPM. We calculated ABPM parameters like morning blood pressure surge (MBPS), ambulatory arterial stiffness index, blood pressure variability, and night dipping patterns.
RESULTS: Multivariate logistic regression analysis indicated that patients in the top quartile of Hcy level tended to have a higher level of prewaking and sleep-trough MBPS compared with patients in the lower 3 quartiles after adjusted for age and gender (P = .028 and P = .030, respectively). When treating Hcy as a continuous variable, the linear regression showed the association between Hcy level and both MBPS parameters remained significant (prewaking MBPS, r = .356, P = .022; sleep-trough MBPS, r = .365, P = .017, respectively). However, there is no association between Hcy level and ambulatory arterial stiffness index, blood pressure variability or night dipping patterns (P = .635, P = .348 and P = .127 respectively).
CONCLUSIONS: There is a relationship between the 2 major cerebrovascular risk factors: MBPS and Hcy.
