One-Year Disability Trajectories and Long-Term Cardiovascular Events, Recurrent Stroke, and Mortality After Ischemic Stroke

How a stroke survivor’s disability evolves over the first year turns out to forecast their longer-term fate. This cohort study mapped those trajectories and linked them to hard outcomes.

Following 3,533 ischemic stroke patients, the investigators identified four distinct one-year disability paths. Those with persistent severe disability faced dramatically elevated risks — sixfold higher all-cause mortality and roughly 2.5-fold higher cardiovascular events and recurrent stroke — compared with patients who stayed minimally disabled. Notably, even patients who improved from severe to moderate disability remained at elevated cardiovascular risk, suggesting the early severe phase leaves a lasting mark.

The practical value is prognostic: a patient’s disability trajectory in the first year is a readily observable signal of who needs the most intensive secondary prevention and monitoring.

We rate the evidence moderate-to-strong. It is a large, well-followed cohort, though observational and outside this library’s central focus on coronary disease; it identifies a useful risk marker without establishing that altering the trajectory changes the downstream outcomes.
