Recurrent vertigo is a predictor of stroke in a large cohort of hypertensive patients
Journal of Hypertension Apr 03, 2019
Courand PY, et al. - In a large cohort of hypertensive patients, researchers focused on the features and the clinical correlates of dizziness, as well as on its prognostic significance for all-cause, cardiovascular, and stroke mortality. Participants included 1716 individuals from the OLD-HTA Lyon's cohort of hypertensive patients. These subjects were divided based on the absence or the presence of dizziness. Further subdivision of the dizziness group into vertigo and other dizziness excluding vertigo was done. By multivariate Cox regression model, the risk for all-cause mortality, cardiovascular mortality, or stroke mortality was not influenced by the presence of dizziness. A prognostic effect was shown by only vertigo in an analysis of the different subgroups of dizziness. Overall, a high-risk profile at baseline was absent in hypertensive patients with dizziness, but higher stroke mortality observed in those with vertigo makes it necessary to carefully follow these subjects over the years.
