Key result
Stroke patients in Poland show ~3-fold higher case fatality rates compared to US patients.
Observational
Yes
Case fatality rates for stroke were ascertained prospectively in two regional catchment hospitals in Poland and 36 teaching hospitals in the US University Hospital Consortium. Case fatality rates in Poland (23.9%) were higher than in the United States (7.5%). Angina, atrial fibrillation, and congestive heart failure were more frequent in Polish stroke patients (40%, 26%, and 25%, respectively) than in US patients (17%, 12%, and 10%). Stroke severity as indicated by higher frequencies of hemiplegia, disordered consciousness, dysphagia, and aphasia was greater in Poland (19%, 39%, 28%, and 42%, respectively) than the United States (11%, 13%, 14%, and 26%).

Ryglewicz et al. (2000) conducted an observational in Ischemic stroke. Hospitalization in Poland vs. Hospitalization in the United States was evaluated on Case fatality rates for stroke. Stroke patients in Poland experienced substantially higher case fatality rates (23.9% vs 7.5%) and greater clinical severity at presentation compared to patients in the United States.
